Improved Cancer Pain Treatment Using Combined Fentanyl-TTS and Tramadol

PAIN PRACTICE, Issue 4 2007
Franco Marinangeli MD
,,Abstract: The aim of the study was to facilitate dose escalation of strong opioids. In this randomized open-label study the influence of tramadol on dose adjustment of transdermal fentanyl in advanced cancer pain control was prospectively evaluated. Seventy patients affected by intractable cancer disease with visual analog scale (VAS) score >3 were enrolled. Thirty-five patients were treated conventionally with increasing transdermal fentanyl dosage as required (group F) and 35 patients received oral tramadol added to their transdermal fentanyl before each increment of the transdermal opioid dosage (group T). Pain control was equally satisfactory in the two groups. VAS scores at baseline (T: 4.36 ± 1.53; F: 4.51 ± 1.36; n.s.) and at the end of the study (T: 1.8 ± 1.6; F: 1.6 ± 1.5; n.s.) did not differ. However, in the tramadol group this level of pain control was achieved with much slower dose escalation of fentanyl. The mean application time of the fentanyl-Transdermal Therapeutic System patch for each dosage (25, 50, 75 ,g/hour) was significantly greater in patients receiving tramadol. No patient in group T escalated to the 100 ,g/hour patch, while in 12 patients of group F the 100 ,g/hour patch was applied after a 75 ,g/hour patch mean application period of 18.6 ± 4.7 days. The number of fentanyl-TTS dosage changes was significantly lower in group T (1.2 ± 0.4 vs. 2.3 ± 0.5; P < 0.05). The mean total duration of treatment in group T, was 37.1 ± 11.6 days. The amount of fentanyl used at study end was 56.6 ± 11.2 ,g/hour plus 141.1 ± 151.9 mg tramadol per day (median: 200 mg/day) in group T patients compared with 84.1 ± 12.2 ,g/hour in group F patients (P < 0.05). The combination of a strong opioid with a weak opioid to treat severe cancer pain allowed a more gradual increase of analgesic delivery than was possible using fentanyl-TTS alone, minimizing periods of under- and overdosing. In addition, it considerably slowed the pace of fentanyl dose escalation. In conclusion, this TTS fentanyl-tramadol analgesic protocol provides a useful alternative to the usual treatment of cancer pain with fentanyl-TTS alone, especially in case of quick progression of disease and pain.,, [source]


Neurophatic Pain Treatment: The Challenge

PAIN PRACTICE, Issue 1 2003
Jose De Andrés
Abstract: Neuropathic pain covers a heterogeneous group of pain conditions characterized by a primary lesion or dysfunction of the sensory nervous system. Its pathophysiology is not yet clear, but neuronal hyperexcitability in those neurons that have lost their normal patterned input seems to be a common denominator for neuropathic pain. A mechanism-based approach is being developed, but still the clinical workup is being based on the anatomical location and the determination of an underlying cause. In addition, clinicians are presented with a challenge because neuropathic pain does not respond well to traditional pain therapies and there are greater individual variations in pain responsiveness. A number of drug classes have been evaluated in the treatment of neuropathic pain syndromes; these are mainly drugs developed for other nervous system diseases, although their precise action and whether their action is central or peripheral remains unknown for the majority of them. First-line agents used in the treatment of neuropathic pain conditions are tricyclic antidepressants and anticonvulsants, especially carbamazepine and gabapentin. Novel therapies are currently being developed for neuropathic pain that are based in experimental models and theoretical frameworks on the pathosphysiological events that initiate this type of pain.

Pain Treatment and Recovery After Endoscopic Sinus Surgery

THE LARYNGOSCOPE, Issue 8 2007
Tatu P Kemppainen MD
Abstract Objectives/Hypothesis: Early recovery and pain management after endoscopic sinus surgery (ESS) are largely unexplored regardless of the large number of ESSs performed by otorhinolaryngologists. In the present study, we evaluated whether scheduled administration of acetaminophen (paracetamol) for pain management after ESS would allow faster recovery to normal daily activities compared with acetaminophen administered on an as needed basis. Study Design: Open, prospective, randomized, controlled clinical trial with two parallel groups. Methods: There were 78 patients who were undergoing ESS and were randomized into two groups. The "scheduled" group (n = 38) was instructed to take two acetaminophen 665 mg modified-release tablets three times a day during the first five postoperative days, whereas the "as needed" group (n = 40) was given instructions to use acetaminophen 665 mg tablets only on an as needed basis. Patients filled in a questionnaire at the follow-up visits on the 7th and 30th postoperative days. The main outcome measures were return to normal daily activities (primary endpoint) and pain during the first week after surgery and patients' satisfaction with pain management (secondary endpoints). Results: Patients returned to their normal daily activities in 8.8 (SD 4.8) days in the "scheduled" group versus in 10.3 (SD 7.0) days in the "as needed" group (mean difference 1.5; 95% CI of the difference ,1.3 to 4.2; P = .29). In the "scheduled" group, the mean of worst pain was 3.4 (2.9) compared with 5.2 (3.0) in the "as needed" group on an 11-point scale (mean difference 1.7; 95% CI of the difference 0.4,5.2; P = .019). The patients in both groups were equally satisfied with pain management. Conclusions: The present study suggests that patients recover in 9 to 10 days after ESS when provided with appropriate pain management. Our data indicate that by prescribing scheduled acetaminophen, postoperative pain after ESS can be controlled effectively without the need for opioid analgesics. [source]


EFNS guidelines on pharmacological treatment of neuropathic pain

EUROPEAN JOURNAL OF NEUROLOGY, Issue 11 2006
N. Attal
Neuropathic pain treatment remains unsatisfactory despite a substantial increase in the number of trials. This EFNS Task Force aimed at evaluating the existing evidence about the pharmacological treatment of neuropathic pain. Studies were identified using first the Cochrane Database then Medline. Trials were classified according to the aetiological condition. All class I and II controlled trials (according to EFNS classification of evidence) were assessed, but lower-class studies were considered in conditions that had no top level studies. Only treatments feasible in an outpatient setting were evaluated. Effects on pain symptoms/signs, quality of life and comorbidities were particularly searched for. Most of the randomized controlled trials included patients with postherpetic neuralgia (PHN) and painful polyneuropathies (PPN) mainly caused by diabetes. These trials provide level A evidence for the efficacy of tricyclic antidepressants, gabapentin, pregabalin and opioids, with a large number of class I trials, followed by topical lidocaine (in PHN) and the newer antidepressants venlafaxine and duloxetine (in PPN). A small number of controlled trials were performed in central pain, trigeminal neuralgia, other peripheral neuropathic pain states and multiple-aetiology neuropathic pains. The main peripheral pain conditions respond similarly well to tricyclic antidepressants, gabapentin, and pregabalin, but some conditions, such as HIV-associated polyneuropathy, are more refractory. There are too few studies on central pain, combination therapy, and head-to-head comparison. For future trials, we recommend to assess quality of life and pain symptoms or signs with standardized tools. [source]

The role of methadone in cancer pain treatment , a review

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 7 2009
W. Leppert
Summary Background:, Methadone is an opioid analgesic of step 3 of the World Health Organization (WHO) analgesic ladder. Aim and Methods:, To outline pharmacodynamics, pharmacokinetics, drug interactions, equianalgesic dose ratio with other opioids, dosing rules, adverse effects and methadone clinical studies in patients with cancer pain. A review of relevant literature on methadone use in cancer pain was conducted. Results:, Methadone is used in opioid rotation and administered to patients with cancer pain not responsive to morphine or other strong opioids when intractable opioid adverse effects appear. Methadone is considered as the first strong opioid analgesic and in patients with renal impairment. Methadone possesses different pharmacodynamics and pharmacokinetics in comparison to other opioids. The advantages of methadone include multimode analgesic activity, high oral and rectal bioavailability, long lasting analgesia, lack of active metabolites, excretion mainly with faeces, low cost and a weak immunosuppressive effect. The disadvantages include long and changeable plasma half-life, high bound to serum proteins, metabolism through P450 system, numerous drug interactions, lack of clear equianalgesic dose ratio to other opioids, QT interval prolongation, local reactions when administered subcutaneously. Conclusions:, Methadone is an important opioid analgesic at step 3 of the WHO analgesic ladder. Future controlled studies may focus on establishment of methadone equianalgesic dose ratio with other opioids and its role as the first strong opioid in comparative studies with analgesia, adverse effects and quality of life taken into consideration.

Daily Variations in Objective Nighttime Sleep and Subjective Morning Pain in Older Adults with Insomnia: Evidence of Covariation over Time

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2010
Joseph M. Dzierzewski MS
OBJECTIVES: To examine the relationship between objectively measured nocturnal sleep and subjective report of morning pain in older adults with insomnia; to examine not only the difference between persons in the association between sleep and pain (mean level over 14 days), but also the within-person, day-to-day association. DESIGN: Cross-sectional. SETTING: North-central Florida. PARTICIPANTS: Fifty community-dwelling older adults (mean age±standard deviation 69.1±7.0, range 60,90) with insomnia. MEASUREMENTS: Daily home-based assessment using nightly actigraphic measurement of sleep and daily self-report of pain over 14 consecutive days. RESULTS: Between persons, average sleep over 14 days was not associated with average levels of rated pain, but after a night in which an older adult with insomnia experienced above-average total sleep time he or she subsequently reported below-average pain ratings. The model explained approximately 24% of the within-person and 8% of the between-person variance in pain ratings. CONCLUSIONS: Sleep and pain show day-to-day associations (i.e., covary over time) in older adults with insomnia. Such associations may suggest that common physiological systems underlie the experience of insomnia and pain. Future research should examine the crossover effects of sleep treatment on pain and of pain treatment on sleep. [source]


Impact of the CYP2D6 genotype on post-operative intravenous oxycodone analgesia

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2010
S. T. ZWISLER
Background: Oxycodone is a semi-synthetic opioid with a ,-receptor agonist-mediated effect in several pain conditions, including post-operative pain. Oxycodone is metabolized to its active metabolite oxymorphone by O -demethylation via the polymorphic CYP2D6. The aim of this study was to investigate whether CYP2D6 poor metabolizers (PMs) yield the same analgesia post-operatively from intravenous oxycodone as extensive metabolizers (EMs). Methods: Two hundred and seventy patients undergoing primarily thyroid surgery or hysterectomy were included and followed for 24 h post-operatively. The CYP2D6 genotype was blinded until study procedures had been completed for all patients. All patients received intravenous oxycodone as pain treatment for 24 h post-operatively and morphine 5 mg was used as escape medication. A responder was characterized as a patient without the need for escape medication and a positive evaluation in a questionnaire 24 h post-operatively. Results: Twenty-four patients were PM (8.9%) and 246 were EM (91.1%). One PM (4.17%, CI=0.1,21.1) was a non-responder and 42 EM (17.07%, CI=12.6,22.4) were non-responders. The non-responder rate did not differ between the two genotypes (P=0.14). There was no difference in the total consumption of oxycodone between the two genotypes (EM=14.7 mg, CI=13.0,16.4 and PM=13.0 mg, CI=8.9,17.0, P=0.42). The mean oxymorphone/oxycodone ratios were 0.0031 and 0.00081 in the EMs and PMs, respectively (P<0.0001). Conclusion: This study showed for the first time in patients that the oxymorphone formation depends on CYP2D6, but we found no difference in the post-operative analgesic effect of intravenous oxycodone between the two CYP2D6 genotypes.

Endocannabinoids, a novel target in pain treatment

JOURNAL OF NEUROCHEMISTRY, Issue 2003
S. C. Azad
Cannabinoids display a variety of central effects including analgesia, control of spasticity and influence of emotional states. Activation of the brain-type cannabinoid receptor CB1 inhibits the adenylyl cyclase-protein kinase A-pathway and modulates calcium and potassium conductances. CB1 is widely distributed throughout the central nervous system. Among other brain regions, CB1 is highly expressed in the amygdala, which is important for the control of emotional behavior including anxiety and pain perception. In a recent investigation using auditory fear-conditioning tests, we showed that the endogenous cannabinoid system in the amygdala is crucially involved in the extinction of aversive memories. Using electrophysiological techniques, we also found that endogenous and exogenously applied cannabinoids play a major role in the modulation of both, synaptic transmission and plasticity in this brain region. Our behavioral and electrophysiological results indicate that the endogenous cannabinoid system may represent a novel target in the treatment of chronic pain. [source]


Pregabalin and dexamethasone in combination with paracetamol for postoperative pain control after abdominal hysterectomy.

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2009
A randomized clinical trial
Background: Multimodal analgesia may be important for optimal postoperative pain treatment and facilitation of early mobilization and recovery. We investigated the analgesic effect of pregabalin and dexamethasone in combination with paracetamol after abdominal hysterectomy. Methods: One hundred and sixteen patients were randomly assigned to either group A (paracetamol+placebo × 2), group B (paracetamol+pregabalin+placebo) or group C (paracetamol+pregabalin+dexamethasone). According to randomization and preoperatively, patients received paracetamol 1000 mg, pregabalin 300 mg, dexamethasone 8 mg or placebo. General anaesthesia was performed. Postoperative pain treatment was paracetamol 1000 mg × 4 and patient-controlled intravenous morphine, 2.5 mg bolus. Nausea was treated with ondansetron. Morphine consumption, pain score (visual analogue scale) at rest and during mobilization, nausea, sedation, dizziness, number of vomits and consumption of ondansetron were recorded 2, 4 and 24 h after the operation. P<0.05 was considered statistically significant. Results: The 24-h morphine consumption and pain score, both at rest and during mobilization, were not significantly different between treatment groups. The mean nausea score (P=0.002) was reduced in group C vs. A. The number of vomits was significantly reduced in both group B (P=0.041) and C (P=0.001) vs. A. Consumption of ondansetron was reduced in group C vs. A and B (P<0.001). Other side effects were not different between groups. Conclusion: Combinations of paracetamol and pregabalin, or paracetamol, pregabalin and dexamethasone did not reduce morphine consumption and pain score compared with paracetamol alone for patients undergoing abdominal hysterectomy. Dexamethasone reduced nausea, vomiting and use of ondansetron. [source]


Primary microparticles and agglomerates of morphine for nasal insufflation

JOURNAL OF PHARMACEUTICAL SCIENCES, Issue 12 2006
Paola Russo
Abstract The aim of this work was to study the characteristics of powders of morphine HCl suitable for nasal administration to be employed for pain treatment as alternative to injection. Primary microparticles of morphine were prepared by spray drying of aqueous drug solutions using sugars or sugar derivatives as drying protectors and particle shapers. The spray drying procedure modified morphine crystallinity making the substance amorphous and affecting its stability in dependence on the excipient employed. A tendency of the spray-dried powders to turn to varying degrees of yellow was observed. Tumbling the powder in a rotating pan allowed the agglomeration of the primary microparticles. Agglomerates were also obtained by tumbling a mixture of morphine crystals and spray-dried microparticles of excipients, with advantages for the stability of the preparation. A nasal device quantitatively insufflated all the morphine agglomerates. The in vitro transport of morphine through rabbit nasal mucosa was faster using nasal powders than with the saturated solution of morphine. Lactose was the most effective excipient for agglomerate manufacturing and delivery of spray-dried morphine. The agglomerates of morphine crystals mixed with mannitol/lecithin microparticles showed superior stability. However, the drug permeation through rabbit mucosa was slower than with spray-dried morphine microparticle agglomerates. © 2006 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 95:2553,2561, 2006 [source]


Sickle Cell Disease: Health Promotion and Maintenance and the Role of Primary Care Nurse Practitioners

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 9 2003
APRN-BC, FNP-C, Ruth A. Tanyi BSJ
Purpose To discuss the role of nurse practitioners (NPs) with regard to early identification of affected individuals, effective monitoring and screening, effective pain management and prophylaxis, and health education for patients with sickle cell disease (SCD). Data Sources Electronic database searches were performed using Medline, Cinahl, and PsycINFO. Data were obtained from medical textbooks, research, and review articles. Conclusions SCD is a chronic inherited disease belonging to a group of conditions called hemo-globinopathies. Individuals with SCD often require close medical care from specialists. Nonetheless, NPs are in ideal positions to facilitate the health promotion and health maintenance necessary to decrease the high rate of morbidity and mortality associated with this disease. Implications for Practice NPs must understand the importance of early identification of affected individuals, effective monitoring and screening, effective pain treatment, and prophylaxis. The unpredictable trajectory of SCD can lead to frustration, fear, helplessness, hopelessness, and emotional distress. Ineffective pain management is a major problem for people with SCD. NPs can overcome this problem by initiating effective and prompt pain management in a nonjudgmental manner. [source]


Breakthrough pain in opioid-treated chronic non-malignant pain patients referred to a multidisciplinary pain centre: a preliminary study

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 10 2006
J. Hřjsted
Background:, Breakthrough pain (BTP) has not formerly been discussed as such in chronic non-malignant pain patients referred to pain centres and clinics. The purpose of the study was to investigate the prevalence, characteristics and mechanisms of BTP in opioid-treated chronic non-malignant pain patients referred to a pain centre and to assess the short-term effects of pain treatment. Methods:, Patients were assessed at referral (T0) and after a treatment period of 3 months (T3) using the visual analogue scale (VAS) of the brief pain inventory (BPI) within somatic nociceptive, neuropathic and/or visceral pain conditions, the mini mental state examination (MMSE) and the hospital anxiety and depression scale (HADS). The main treatment intervention from T0 to T3 was to convert short-acting oral opioids to long-acting oral opioids and to discontinue on demand and parenteral use of opioids. Results:, Thirty-three patients were assessed at T0 and 27 at T3. The prevalence of BTP declined significantly from T0 (90%) to T3 (70.4%). Worst, least, average and current pain intensities as well as duration of BTP were significantly reduced from T0 to T3. The majority of BTPs were exacerbation of background pain assumed to be of the same pain mechanisms. High average pain intensity (BPI) was significantly associated with high scores for both anxiety and depression (HADS). Conclusion:, BTP in chronic non-malignant pain patients seems to be surprisingly frequent and severe. Stabilizing the opioid regimen seems to reduce pain intensity in general as well as the intensity and duration of BTP. Average pain intensity was associated with anxiety and depression. [source]


,Protective premedication': an option with gabapentin and related drugs?

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2004
A review of gabapentin, pregabalin in the treatment of post-operative pain
Substantial progress has been made during the last decades in our understanding of acute pain mechanisms, and this knowledge has encouraged the search for novel treatments. Of particular interest has been the observation that tissue injury initiates a number of modulations of both the peripheral and the central pain pathways, which convert the system from a ,physiological' to a ,pathological' mode of processing afferent information. Gabapentin, which binds to the ,2, subunit of the voltage-dependent calcium channel, is active in animal models of ,pathological' but not in models of ,physiological' pain. Consequently, attention has so far been focused on neuropathic pain as a target for the clinical use of gabapentin and analogues. Recently, several reports have indicated that gabapentin may have a place in the treatment of post-operative pain. This article presents a brief summary of the potential mechanisms of post-operative pain, and a systematic review of the available data of gabapentin and pregabalin for post-operative analgesia. It is concluded that the results with gabapentin and pregabalin in post-operative pain treatment published so far are promising. It is suggested that future studies should explore the effects of ,protective premedication' with combinations of various antihyperalgesic and analgesic drugs for post-operative analgesia. [source]


Transcutaneous Electrical Nerve Stimulation as Prehospital Emergency Interventional Care: Treating Acute Pelvic Pain in Young Women

NEUROMODULATION, Issue 2 2006
Renate Barker MD
Abstract Objectives., In Europe, patients with acute pelvic pain are transported to the hospital in an ambulance without an emergency physician. We hypothesized that transcutaneous electrical nerve stimulation (TENS) would be an effective noninvasive procedure for pain treatment. Methods., We conducted a prospective, randomized, blinded study where 100 women were randomly assigned into a real- or a sham-TENS group. TENS began before the transport to the ambulance and was left in place until the arrival at the hospital. Each patient rated her pain on paper using a visual analog scale. Results., Compared to sham TENS, patients with active TENS felt that their pain was reduced by half after treatment (p < 0.01), anxiety scores significantly decreased (p < 0.01), heart rate and arteriolar vasoconstriction decreased significantly (p < 0.01), and nausea (p < 0.01) was lessened. Overall satisfaction with the received care was significantly higher (p < 0.01). Conclusion., TENS is a safe, rapid, and effective analgesic treatment for acute pelvic pain. [source]


Do Pain Patients at High Risk for Substance Misuse Experience More Pain?: A Longitudinal Outcomes Study

PAIN MEDICINE, Issue 6 2009
Robert N. Jamison PhD
ABSTRACT Objectives., The Screener and Opioid Assessment of Pain Patients (SOAPP v.1) has been shown to be a reliable measure of risk potential for substance misuse and to correlate with a history of substance abuse, legal problems, craving, smoking, and mood disorders among chronic pain patients. The aim of this study was to examine differences over time on a number of measures among chronic pain patients who were classified as high or low risk for opioid misuse based on scores on the SOAPP. Methods., From an initial sample of one hundred thirty-four participants (N = 134), one hundred and ten (N = 110) completed the SOAPP and were grouped as high or low risk for misuse of medication based on SOAPP scores of ,7. All subjects were asked to complete baseline measures and in-clinic monthly diaries of their pain, mood, activity interference, medication, and side effects over a 10-month study period. Results., The results showed that although those who were classified as high-risk for opioid misuse reported significantly higher levels of pain intensity, activity interference, pain catastrophizing, disability, and depressed mood at baseline (P < 0.05), only pain intensity ratings were found to differentiate groups over time (P < 0.01). These results were unrelated to perceived helpfulness of pain treatment. Conclusions., Differences in subjective pain intensity were found between those who are high risk for opioid misuse compared with those at low risk for medication misuse, implying that higher-risk patients may experience more subjective pain. Consequently, these patients may be more challenging to treat. [source]


Assessment and Treatment of Pain Associated with Combat-Related Polytrauma

PAIN MEDICINE, Issue 3 2009
Michael E. Clark PhD
ABSTRACT Due to the high rates of blast injuries sustained during operations in Iraq and Afghanistan, the number of soldiers returning with massive and multiple wounds is unprecedented. While casualty survival rates have improved dramatically, the extent and impact of these wounds on soldiers' functioning pose unique challenges for their rehabilitation. Pain is highly prevalent in these individuals with polytrauma injuries and is a source of suffering, as well as an impediment to rehabilitation. However, there are a number of obstacles to effective pain treatment in this group of war-injured, including their multiple and severe injuries, the high prevalence of brain injuries, cognitive impairments and emotional distress, the prolonged and intensive rehabilitation process, and the frequent need for repeated follow-up surgeries. As a result, we believe that a comprehensive, interdisciplinary approach to pain treatment is required. In this article we describe the model of pain care that has evolved at the Tampa Polytrauma Rehabilitation Center, which incorporates medical, rehabilitative, cognitive,behavioral, and interventional treatments targeting pain intensity as well as pain-related impairments and coping. We include a case study illustrating some key aspects of our approach. [source]


Prevalence and Characteristics of Chronic Pain in Patients Admitted to an Outpatient Drug and Alcohol Treatment Program

PAIN MEDICINE, Issue 7 2008
Robert Sheu MD
ABSTRACT Objectives., To evaluate the prevalence, characteristics, and correlates of chronic pain in a population of predominantly employed, alcoholic patients attending an outpatient drug and alcohol treatment program. Methods., A pain survey was administered to 79 patients attending an outpatient drug and alcohol treatment program situated in a suburban community outside of New York City. Chronic severe pain was defined as pain that 1) had persisted for at least 6 months; and 2) was either moderate to severe in intensity or significantly interfered with daily activities. Results., Seventy-six percent of patients experienced pain during the past week. Chronic severe pain was experienced by 29.1% of patients. High levels of pain interference with physical and psychosocial functioning were reported by 26.1%. Patients with chronic severe pain were more likely to have significant comorbidity, to cite physical pain as the impetus for alcohol or drug abuse, to have abused a prescription drug or used an illicit drug to treat pain during the prior 3 months, and to have used illicitly obtained opioids. Only 13% of patients with chronic severe pain were currently receiving pain treatment and 72% expressed interest in receiving treatment. Discussion., Chronic severe pain was prevalent in this predominantly employed, alcoholic population attending an outpatient drug and alcohol treatment program. Pain was associated with significant functional impairment, medical and psychiatric comorbidities, and abuse behaviors. Few patients accessed adequate pain treatment. Efforts should be made to better address the pain problems in this patient population. [source]


Veterans Affairs Primary Care Clinicians' Attitudes toward Chronic Pain and Correlates of Opioid Prescribing Rates

PAIN MEDICINE, Issue 5 2008
Steven K. Dobscha MD
ABSTRACT Objectives., The primary objective of this study was to identify veterans affairs (VA) primary care clinicians' attitudes regarding chronic pain treatment. A secondary objective was to explore relationships between clinician and practice characteristics and an objective measure of opioid prescribing rates. Design., Cross-sectional study of clinician survey and pharmacy data. Participants., Forty-five VA clinicians from five primary care clinics of one VA medical center. Measures., Survey of pain-related attitudes and behaviors, satisfaction with treatment resources, and job satisfaction; percentage of patients in clinicians' panels prescribed opioids (PCPO). Results., Seventy-one percent of clinicians felt moderately or strongly confident in their ability to treat chronic pain, and 77% moderately or strongly agreed that skilled pain management is a high priority. However, 73% moderately or strongly agreed that patients with chronic pain are a major source of frustration and 38% reported moderate or greater dissatisfaction with their ability to provide optimal pain treatment. Fifty-two percent moderately or strongly agreed that their management is influenced by previous experiences with patients addicted to drugs. The mean PCPO was 16.5% (SD = 6.7). In bivariate comparisons, clinician panel size, job and resource satisfaction, and professional training were associated with opioid prescribing rates. Conclusion., High clinician confidence and interest in treating chronic pain concurrent with low satisfaction with ability to provide optimal treatment suggests a need for more system support. VA primary care clinicians are frequently influenced by fears of contributing to dependence or addiction. The relationships among panel size, job satisfaction, and opioid prescribing rates merit additional investigation. [source]


Disparity vs Inequity: Toward Reconceptualization of Pain Treatment Disparities

PAIN MEDICINE, Issue 5 2008
CRNP, Salimah H. Meghani PhD
ABSTRACT Context., "Disparity" and "inequity" are two interdependent, yet distinct concepts that inform our discourse on ethics and morals in pain medicine practice and in health policy. Disparity implies a difference of some kind, whereas inequity implies unfairness and injustice. An overwhelming body of literature documents racial/ethnic disparities in health. The debate on health disparities is generally formulated using the principle of "horizontal equity," which requires that individuals having the same needs be treated equally. While some types of health treatments are amenable to the principle of horizontal equity, others may not be appropriately studied in this way. The existing research surrounding racial/ethnic disparities in pain treatment presents a conceptual predicament when placed within the framework of horizontal equity. Objective., Using pain treatment as a prototype, we advance the conceptual debate about racial/ethnic disparities in health. More specifically, we ask three questions: (1) When may disparities be considered inequities? (2) When may disparities not be considered inequities? (3) What are the uncertainties in the disparity,inequity discourse? Discussion., Significant policy implications may result from the manner in which health disparities are conceptualized. Increasingly, researchers and policy makers use the term disparity interchangeably with inequity. This usage confuses the meaning and application of these distinct concepts. In a given health care setting, different types of disparities may operate simultaneously, each requiring serious scrutiny to avoid categorical interpretation leading to misguided practice and policy. While the science of pain treatment disparities is still emerging, the authors present one perspective toward the conceptualization of racial/ethnic disparities in pain treatment. [source]


Phenol Neurolysis for Severe Chronic Nonmalignant Pain: Is the Old also Obsolete?

PAIN MEDICINE, Issue 4 2007
Natan Weksler MD
ABSTRACT Objective., Our purpose was to reassess the effectiveness of phenol 4% in aqueous solution for neurolysis in patients with severe chronic nonmalignant pain syndromes who did not achieve adequate pain control (visual analog scale [VAS] ,3) with conventional pain treatment. Design., Forty-two patients with severe nonmalignant pain persisting for 6 months or longer were followed for more than 6 months after phenol neurolysis in this prospective observational study. All patients had previously received narcotic drugs, with or without nonsteroidal anti-inflammatory agents or adjuvants, without adequate pain relief. An aqueous solution of phenol 4% was used for chemical neurolysis. A fluoroscopically guided technique was used for chemical lumbar sympathectomy, medial branch destruction, and sacroiliac injections. Anatomic-landmarks technique was used for intercostal neurolysis, greater occipital nerve destruction, genitofemoral neuroablation, and paracoccygeal infiltration. Results., Good pain relief (VAS ,3) was achieved in 35 patients after neurolysis with phenol, and the mean VAS decreased from 8.74 ± 1.08 (range 7,10) before treatment to 1.93 ± 2.41 after treatment (P < 0.0001). The mean VAS for assessment of the quality of pain relief after phenol neurolysis was 8.4 ± 2.39, ranging from 0 (no relief at all) to 10 (complete relief ). No major complications were seen. Conclusion., The use of phenol 4% in aqueous solution is an effective and safe technique for neurolysis. Because of the potential risk of flaccid paralysis, this technique should be used in selected cases, far removed from motor nerves and the spinal cord. [source]


The Unequal Burden of Pain: Confronting Racial and Ethnic Disparities in Pain

PAIN MEDICINE, Issue 3 2003
Carmen R. Green MD
ABSTRACT context. Pain has significant socioeconomic, health, and quality-of-life implications. Racial- and ethnic-based differences in the pain care experience have been described. Racial and ethnic minorities tend to be undertreated for pain when compared with non-Hispanic Whites. objectives. To provide health care providers, researchers, health care policy analysts, government officials, patients, and the general public with pertinent evidence regarding differences in pain perception, assessment, and treatment for racial and ethnic minorities. Evidence is provided for racial- and ethnic-based differences in pain care across different types of pain (i.e., experimental pain, acute postoperative pain, cancer pain, chronic non-malignant pain) and settings (i.e., emergency department). Pertinent literature on patient, health care provider, and health care system factors that contribute to racial and ethnic disparities in pain treatment are provided. evidence. A selective literature review was performed by experts in pain. The experts developed abstracts with relevant citations on racial and ethnic disparities within their specific areas of expertise. Scientific evidence was given precedence over anecdotal experience. The abstracts were compiled for this manuscript. The draft manuscript was made available to the experts for comment and review prior to submission for publication. conclusions. Consistent with the Institute of Medicine's report on health care disparities, racial and ethnic disparities in pain perception, assessment, and treatment were found in all settings (i.e., postoperative, emergency room) and across all types of pain (i.e., acute, cancer, chronic nonmalignant, and experimental). The literature suggests that the sources of pain disparities among racial and ethnic minorities are complex, involving patient (e.g., patient/health care provider communication, attitudes), health care provider (e.g., decision making), and health care system (e.g., access to pain medication) factors. There is a need for improved training for health care providers and educational interventions for patients. A comprehensive pain research agenda is necessary to address pain disparities among racial and ethnic minorities. [source]


(229) Serum Cortisol Concentrations and Adrenal Reserve May Be Altered by Severe Chronic Pain

PAIN MEDICINE, Issue 3 2001
Forest Tennant
It has been postulated that chronic pain over-stimulates the hypothalamus-pituitary-adrenal axis to produce an extended stress response. If this assumption is true, patients with severe, chronic pain should demonstrate abnormalities of the pituitary-adrenal axis. To evaluate this premise, we screened 40 adult, chronic pain patients in the first week of treatment with serum cortisol concentrations taken between 8:00 and 10:00 AM. Criteria for inclusion in this study required that pain be present for at least one year and be constant, incurable, interfere with sleep, and cause the patient to be bed or house-bound without opioid treatment. Sixteen (16) of the subjects were challenged with cosyntropin, 0.25mg, given intramuscularly immediately after blood was drawn for determination of baseline serum cortisol concentration. Normal serum cortisol concentrations was considered to range from 5.0 to 25.0 ug/dl at baseline, and normal cortisol reserve was considered to be at least a doubling of the baseline concentration determined one hour after cosyntropin administration. Ten (25%) of the patients had evaluated serum cortisol concentrations above 25ug/dl with the highest being 54.4 ug/dl. Nine (20%) demonstrated low serum cortisol concentrations under 5 ug/dl, and 5 of 16 (31.25%) given cosyntropin challenge demonstrated inadequate adrenal reserve by failing to double their baseline cortisol concentration. All patients with high or low serum cortisol concentration demonstrated a normal cortisol concentration following pain control with a long-acting opioid including methadone, extended-length morphine or oxycodone, or transdermal fentanyl. This study suggests that severe, chronic pain may produce profound abnormalities of serum cortisol and cortisol reserve, and normalization of these alterations may require pain treatment with long-acting opioids.

Identifying Patients at Risk for Loss to Follow-up After Pain Center Treatment

PAIN MEDICINE, Issue 1 2001
Robert B. Cutler PhD
Objective., This study was designed to identify, at admission to a pain treatment facility, characteristics of patients who will be lost to follow-up after treatment completion. Method., Patients were divided into 3 groups depending on how they responded to the 12-month follow-up. The analysis was a between-subjects design using prospective data collected at a comprehensive pain treatment facility. Low back pain patients (n = 168) received 4 weeks of multidisciplinary pain treatment. The main outcome measure was response/nonresponse to follow-up questionnaires. Results. showed that patients who were later lost to follow-up, or who were reluctant to answer follow-ups, could be predicted at treatment admission by measures of pain and functioning. The prediction equation was validated by a second group of patients, treatment noncompleters (n = 55). Conclusion., Chronic pain patients who are more likely to be lost to follow-up can be identified upon admission to a pain facility. Procedures that should decrease follow-up attrition could be implemented at program admission. [source]


Opioids and the Management of Chronic Severe Pain in the Elderly: Consensus Statement of an International Expert Panel with Focus on the Six Clinically Most Often Used World Health Organization step III Opioids (Buprenorphine, Fentanyl, Hydromorphone, Methadone, Morphine, Oxycodone)

PAIN PRACTICE, Issue 4 2008
Joseph Pergolizzi MD
,,Abstract Summary of consensus: 1.,The use of opioids in cancer pain:, The criteria for selecting analgesics for pain treatment in the elderly include, but are not limited to, overall efficacy, overall side-effect profile, onset of action, drug interactions, abuse potential, and practical issues, such as cost and availability of the drug, as well as the severity and type of pain (nociceptive, acute/chronic, etc.). At any given time, the order of choice in the decision-making process can change. This consensus is based on evidence-based literature (extended data are not included and chronic, extended-release opioids are not covered). There are various driving factors relating to prescribing medication, including availability of the compound and cost, which may, at times, be the main driving factor. The transdermal formulation of buprenorphine is available in most European countries, particularly those with high opioid usage, with the exception of France; however, the availability of the sublingual formulation of buprenorphine in Europe is limited, as it is marketed in only a few countries, including Germany and Belgium. The opioid patch is experimental at present in U.S.A. and the sublingual formulation has dispensing restrictions, therefore, its use is limited. It is evident that the population pyramid is upturned. Globally, there is going to be an older population that needs to be cared for in the future. This older population has expectations in life, in that a retiree is no longer an individual who decreases their lifestyle activities. The "baby-boomers" in their 60s and 70s are "baby zoomers"; they want to have a functional active lifestyle. They are willing to make trade-offs regarding treatment choices and understand that they may experience pain, providing that can have increased quality of life and functionality. Therefore, comorbidities,including cancer and noncancer pain, osteoarthritis, rheumatoid arthritis, and postherpetic neuralgia,and patient functional status need to be taken carefully into account when addressing pain in the elderly. World Health Organization step III opioids are the mainstay of pain treatment for cancer patients and morphine has been the most commonly used for decades. In general, high level evidence data (Ib or IIb) exist, although many studies have included only few patients. Based on these studies, all opioids are considered effective in cancer pain management (although parts of cancer pain are not or only partially opioid sensitive), but no well-designed specific studies in the elderly cancer patient are available. Of the 2 opioids that are available in transdermal formulation,fentanyl and buprenorphine,fentanyl is the most investigated, but based on the published data both seem to be effective, with low toxicity and good tolerability profiles, especially at low doses. 2.,The use of opioids in noncancer-related pain:, Evidence is growing that opioids are efficacious in noncancer pain (treatment data mostly level Ib or IIb), but need individual dose titration and consideration of the respective tolerability profiles. Again no specific studies in the elderly have been performed, but it can be concluded that opioids have shown efficacy in noncancer pain, which is often due to diseases typical for an elderly population. When it is not clear which drugs and which regimes are superior in terms of maintaining analgesic efficacy, the appropriate drug should be chosen based on safety and tolerability considerations. Evidence-based medicine, which has been incorporated into best clinical practice guidelines, should serve as a foundation for the decision-making processes in patient care; however, in practice, the art of medicine is realized when we individualize care to the patient. This strikes a balance between the evidence-based medicine and anecdotal experience. Factual recommendations and expert opinion both have a value when applying guidelines in clinical practice. 3.,The use of opioids in neuropathic pain:, The role of opioids in neuropathic pain has been under debate in the past but is nowadays more and more accepted; however, higher opioid doses are often needed for neuropathic pain than for nociceptive pain. Most of the treatment data are level II or III, and suggest that incorporation of opioids earlier on might be beneficial. Buprenorphine shows a distinct benefit in improving neuropathic pain symptoms, which is considered a result of its specific pharmacological profile. 4.,The use of opioids in elderly patients with impaired hepatic and renal function:, Functional impairment of excretory organs is common in the elderly, especially with respect to renal function. For all opioids except buprenorphine, half-life of the active drug and metabolites is increased in the elderly and in patients with renal dysfunction. It is, therefore, recommended that,except for buprenorphine,doses be reduced, a longer time interval be used between doses, and creatinine clearance be monitored. Thus, buprenorphine appears to be the top-line choice for opioid treatment in the elderly. 5.,Opioids and respiratory depression:, Respiratory depression is a significant threat for opioid-treated patients with underlying pulmonary condition or receiving concomitant central nervous system (CNS) drugs associated with hypoventilation. Not all opioids show equal effects on respiratory depression: buprenorphine is the only opioid demonstrating a ceiling for respiratory depression when used without other CNS depressants. The different features of opioids regarding respiratory effects should be considered when treating patients at risk for respiratory problems, therefore careful dosing must be maintained. 6.,Opioids and immunosuppression:, Age is related to a gradual decline in the immune system: immunosenescence, which is associated with increased morbidity and mortality from infectious diseases, autoimmune diseases, and cancer, and decreased efficacy of immunotherapy, such as vaccination. The clinical relevance of the immunosuppressant effects of opioids in the elderly is not fully understood, and pain itself may also cause immunosuppression. Providing adequate analgesia can be achieved without significant adverse events, opioids with minimal immunosuppressive characteristics should be used in the elderly. The immunosuppressive effects of most opioids are poorly described and this is one of the problems in assessing true effect of the opioid spectrum, but there is some indication that higher doses of opioids correlate with increased immunosuppressant effects. Taking into consideration all the very limited available evidence from preclinical and clinical work, buprenorphine can be recommended, while morphine and fentanyl cannot. 7.,Safety and tolerability profile of opioids:, The adverse event profile varies greatly between opioids. As the consequences of adverse events in the elderly can be serious, agents should be used that have a good tolerability profile (especially regarding CNS and gastrointestinal effects) and that are as safe as possible in overdose especially regarding effects on respiration. Slow dose titration helps to reduce the incidence of typical initial adverse events such as nausea and vomiting. Sustained release preparations, including transdermal formulations, increase patient compliance.,, [source]


Anesthesia in HIV-infected children

PEDIATRIC ANESTHESIA, Issue 6 2007
RUENREONG LEELANUKROM
Summary In 2005, it was estimated that 2.3 million children below15 years of age were living with human immunodeficiency virus (HIV)/AIDS and 570 000 children below 15 years died. Maternal-infant or vertical transmission is the most common mode of HIV infection in children. As transplacental passage of maternal anti-HIV antibodies, diagnosis of HIV infection in young infants relies on virologic assays. Infants older than 18 months of age can be diagnosed by serology alone. Pediatric HIV infections are classified according to Center for Disease Control and Prevention 1994 revised classification system. The understanding of viral pathogenesis, the development of highly active antiretroviral therapy, and the ability to quantitate viral burden have led to significant reduction in disease progression and morbidity in HIV-infected children. As survival improves, these children will require anesthesia care and pain treatment during the course of their illness. Considerations for the anesthesiologist include: possible involvement of multiple organ systems, adverse reactions and drug interactions of antiretroviral agents and adequate infection control to prevent HIV transmission in hospital and other infections to the immunocompromized patients. Finally, care should be taken not to violate confidentiality. [source]


Postoperative continuous intrathecal pain treatment in children after selective dorsal rhizotomy with bupivacaine and two different morphine doses

PEDIATRIC ANESTHESIA, Issue 4 2006
KARIN HESSELGARD RN
Summary Background:, Children undergoing selective dorsal rhizotomy (SDR) experience severe pain postoperatively; a pain related to both the extensive surgical exposure with multilevel laminectomy and nerve root manipulation. We sought to define an optimal dose of continuous intrathecal (IT) morphine and bupivacaine to treat this severe pain. The aim of this study was to compare two different concentrations of morphine in a fixed dose of bupivacaine with regard to the analgesic effect and survey if they differed in side effects. Methods:, Twenty-six children, aged 2.7,7.4 years undergoing SDR were included in this study. Postoperatively 11 children received a continuous infusion of morphine 0.4 ,g.kg,1.h,1 and bupivacaine 40 ,g.kg,1.h,1 (low-dose group) and 15, a continuous infusion of morphine 0.6 ,g.kg,1.h,1 and bupivacaine 40 ,g.kg,1.h,1 (high-dose group). The Behavioral Observational Pain Scale (BOPS) was used to evaluate pain. Results:, Better pain relief was obtained in the high-dose group seen in lower BOPS score compared with the low-dose group [P = 0.03, Fisher's permutation test and P = 0.06 Wilcoxon,Mann,Whitney (WMW) test]. The low-dose group received seven times as much ketobemidone 0.43 ± 0.54 mg.kg,1 48 h,1 compared with 0.06 ± 0.09 mg.kg,1 48 h,1 in the high-dose group (P = 0.0005 Fisher's permutation test, P = 0.0017 WMW test). There was no statistical difference in pruritus and postoperative nausea and vomiting between the groups. Respiratory and hemodynamic depression was not found. Conclusion:, This study shows that, compared with low-dose, the higher dose of continuous IT morphine combined with bupivacaine, significantly reduce pain score and postoperative intravenous analgesic requirements without increasing adverse effects.

The feasibility of pain treatment at home after adenoidectomy with ketoprofen tablets in small children

PEDIATRIC ANESTHESIA, Issue 5 2000
Hannu Kokki MD
In this study, we investigated the feasibility of pain treatment using ketoprofen 25 mg tablets (5 mg·kg,1·day,1) at home in children after daycase adenoidectomy. We also determined the adverse events and the incidence of postoperative bleeding during the first week after surgery. Initially, we studied 611 children aged 1,9 years. The study design was prospective, longitudinal, and open. The final data consisted of 555 (91%) children, and 522 children who received ketoprofen at home. The parents administered four (1,10, median with 10th and 90th percentiles) ketoprofen tablets to their children during the first week. A total of 20% of the parents experienced problems in administering tablets, and problems were three times more common in children under 48 months compared to older children. The main problems were swallowing difficulties and the unpleasant taste of the tablet. Neither serious adverse events, nor clinically significant bleeding occurred. Ketoprofen at the dose of 5 mg·kg,1·day,1 proved to be a safe analgesic in children for short-term use after adenoidectomy. [source]
