Gender Disparity in Analgesic Treatment of Emergency Department Patients with Acute Abdominal Pain

ACADEMIC EMERGENCY MEDICINE, Issue 5 2008
Esther H. Chen MD
Abstract Objectives:, Oligoanalgesia for acute abdominal pain historically has been attributed to the provider's fear of masking serious underlying pathology. The authors assessed whether a gender disparity exists in the administration of analgesia for acute abdominal pain. Methods:, This was a prospective cohort study of consecutive nonpregnant adults with acute nontraumatic abdominal pain of less than 72 hours' duration who presented to an urban emergency department (ED) from April 5, 2004, to January 4, 2005. The main outcome measures were analgesia administration and time to analgesic treatment. Standard comparative statistics were used. Results:, Of the 981 patients enrolled (mean age ± standard deviation [SD] 41 ± 17 years; 65% female), 62% received any analgesic treatment. Men and women had similar mean pain scores, but women were less likely to receive any analgesia (60% vs. 67%, difference 7%, 95% confidence interval [CI] = 1.1% to 13.6%) and less likely to receive opiates (45% vs. 56%, difference 11%, 95% CI = 4.1% to 17.1%). These differences persisted when gender-specific diagnoses were excluded (47% vs. 56%, difference 9%, 95% CI = 2.5% to 16.2%). After controlling for age, race, triage class, and pain score, women were still 13% to 25% less likely than men to receive opioid analgesia. There was no gender difference in the receipt of nonopioid analgesia. Women waited longer to receive their analgesia (median time 65 minutes vs. 49 minutes, difference 16 minutes, 95% CI = 3.5 to 33 minutes). Conclusions:, Gender bias is a possible explanation for oligoanalgesia in women who present to the ED with acute abdominal pain. Standardized protocols for analgesic administration may ameliorate this discrepancy. [source]


Use of web-based data collection to evaluate analgesic administration and the decision for surgery in horses with colic

EQUINE VETERINARY JOURNAL, Issue 4 2005
N. A. WHITE
Summary Reasons for performing study: There is no current veterinary information with regard to data entry on a website. We therefore completed a prospective study on use of analgesics in relation to the need for abdominal surgery using a web-based survey instrument. Objectives: To establish an internet-based data entry system that could be used to record prospective data on horses with colic. Hypothesis: Failure of horses to respond to the initial administration of an analgesic is an indicator of the need for abdominal surgery. Methods: A survey was developed to determine if the response to administration of an analgesic during a veterinarian's first examination of a horse with colic was related to the need for surgery. Veterinarians were contacted via AAEP and ECN listservs requesting submission of cases using a log-in system at a data entry website. The survey was completed by submission of a data entry page. Results: Twenty-seven veterinarians submitted details of 119 cases of colic, 28 of which required surgery. The need for surgery was significantly associated with moderate or severe pain observed during the first examination compared to mild or no pain, and with constant pain or return of pain after administration of one or more analgesics and the need to administer a second analgesic treatment. Abnormal findings on rectal examination were not associated with the need for surgery, whereas total absence or decrease of intestinal sounds was significantly related to the odds that surgery was needed. The web-based data collection was successful in collecting all data points on the survey for each case. Conclusions: This study reinforced veterinarians' use of response to therapy as a way to determine the need for abdominal surgery. Potential relevance: When a specific diagnosis has not been made, lack of response or resumption of colic after analgesic administration should be considered as an indicator of the need for surgery. Web-based collection of data allows veterinary practitioners to participate in clinical research by providing prospective data. [source]


Prediction of post-operative pain by an electrical pain stimulus

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2007
P. R. Nielsen
Background:, Treatment of post-operative pain is still a significant problem. Recently, interest has focused on pre-operative identification of patients who may experience severe post-operative pain in order to offer a more aggressive analgesic treatment. The nociceptive stimulation methods have included heat injury and pressure algometry. A simple method, Pain Matcher® (PM), using electrical stimulation, is validated for pain assessment, but has not been evaluated as a tool for prediction of post-operative pain. Our aim was to assess the predictive value of pre-caesarean section pain threshold on intensity of post-caesarean section pain using the PM. Patients and methods:, Thirty-nine healthy women scheduled for elective caesarean section were studied. The anaesthetic/analgesic procedures included spinal anaesthesia, paracetamol, diclofenac, controlled-release (CR) oxycodone and morphine on request. Pre-operatively, the sensory and pain thresholds were measured using the PM. Post-operatively, a midwife, blinded for pre-caesarean pain threshold assessments, assessed the pain at rest and during mobilization every 12 h for 2 days. Consumption of analgesics was also recorded. Results:, Pre-operative pain threshold correlated significantly with post-caesarean pain score (VAS) at rest and mobilization: [Spearman's rho =,0.65 (,0.30 to ,0.75), P < 0.01] and [Spearman's rho =,0.52 (,0.23 to ,0.72), P < 0.01], respectively. There was no significant correlation between pre-operative PM assessment of sensory threshold and post-operative pain. Conclusion:, Electrical pain threshold before caesarean section seems to predict the intensity of post-operative pain. This method may be used as a screening tool to identify patients at high risk of post-operative pain. [source]


Epidural Catheter Analgesia in Dogs and Cats: Technique and Review of 182 Cases (1991,1999)

JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 2 2001
Bernie D. Hansen DVM, DACVECC
Abstract Objective: To characterize the indications and techniques for catheterization of the epidural space to treat pain in dogs and cats in a veterinary teaching hospital intensive care unit, and describe the analgesic regimens used in those patients. To provide a detailed description of the technique of epidural catheterization in companion animals. Design: Retrospective case series and clinical practice review. Setting: The Veterinary Teaching Hospital at the North Carolina State University College of Veterinary Medicine. Animals: Records from 160 dogs and 22 cats that had epidural catheters placed were identified. Interventions: Epidural catheterization for the purpose of providing analgesia for a variety of surgical and medical disorders was performed on both awake and anesthetized patients. Measurements and main results: The most frequently used analgesic agents were preservative-free morphine and bupivacaine. 2The range of duration of catheter dwell time was 1.3,332 hours, with a mean duration of 50 hours and a median of 39 hours. Suspicion of catheter malpositioning prompted radiographic imaging of the catheter in 44 patients, and malpositioning was confirmed in 6 of those. Catheter tip positioning was recorded in 46 patients. The tip was located at L3-L6 in 16, and T5-L3 in 30. Twenty-seven of those 30 patients were catheterized to treat pain associated with thoracotomy, forelimb amputation, pancreatitis, or peritonitis. Fifty-one (28%) patients received no analgesics beyond those provided by the epidural catheter. Conclusions: Epidural administration of analgesia appeared to provide significant pain relief and was adequate as a sole analgesic treatment in some patients. Serious complications in these critically ill animals appeared to be uncommon. (J Vet Emerg Crit Care 2001; 11(2): 95,103) [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]


Reduced Cold Pain Tolerance in Chronic Pain Patients Following Opioid Detoxification

PAIN MEDICINE, Issue 8 2008
Jarred Younger PhD
ABSTRACT Objective., One potential consequence of chronic opioid analgesic administration is a paradoxical increase of pain sensitivity over time. Little scientific attention has been given to how cessation of opioid medication affects the hyperalgesic state. In this study, we examined the effects of opioid tapering on pain sensitivity in chronic pain patients. Design., Twelve chronic pain patients on long-term opioid analgesic treatment were observed in a 7- to 14-day inpatient pain rehabilitation program, with cold pain tolerance assessed at admission and discharge. The majority of participants were completely withdrawn from their opioids during their stay. Outcome Measures., We hypothesized that those patients with the greatest reduction in daily opioid use would show the greatest increases in pain tolerance, as assessed by a cold pressor task. Results., A linear regression revealed that the amount of opioid medication withdrawn was a significant predictor of pain tolerance changes, but not in the direction hypothesized. Greater opioid reduction was associated with decreased pain tolerance. This reduction of pain tolerance was not associated with opioid withdrawal symptoms or changes in general pain. Conclusions., These findings suggest that the withdrawal of opioids in a chronic pain sample leads to an acute increase in pain sensitivity. [source]


Large-scale stopping and switching treatment with COX-2 inhibitors after the rofecoxib withdrawal,

PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 1 2008
Myrthe P. P. Sukel MSc
Abstract Purpose To compare treatment changes after the rofecoxib withdrawal with changes occurring normally and to re-assess 12 months afterwards. Methods The PHARMO database comprised medication and hospital discharge records of over 3 million inhabitants in the Netherlands. The Study cohort included chronic coxib users with a coxib prescription on 30th September 2004; the Reference cohort others with a coxib prescription on 1st June 2004. Initial treatment changes were based on first new prescription since cohort entry. Twelve-month changes were studied within the Study cohort only. Results The Study cohort (n,=,6974) and Reference cohort (n,=,5393) had similar demographics, stratified on type of coxib. In the Study cohort, 3341 (48%) initially stopped coxibs, of whom 1121 (16%) stopped all analgesic, versus 13 and 5% in the Reference cohort (p,<,0.001). Among ,other coxib' users 32% stopped coxibs, and 15% stopped all analgesics, versus 14% and 4%, p,<,0.001 in the Reference cohort. Among those who stopped coxibs, 34% switched to non-selective non-steroidal anti-inflammatory drug (nsNSAID) without PPI, 21% to nsNSAID with PPI, and 45% stopped NSAID treatment (Reference cohort: 35, 20, and 44%, respectively). These rates for ,other coxib users' were: switching to nsNSAID without PPI 23% (Study Cohort) versus 35% (Reference Cohort), 13 versus 28%, and 64 versus 37% respectively (p,<,0.001). Twelve months later, stopping NSAID increased to 43%, stopping all analgesics to 32%. Rheumatologists continued coxibs more frequently than other caregivers (87, 65, 54%, respectively). Conclusions The rofecoxib withdrawal resulted in a large proportion of patients who discontinued analgesic treatment altogether regardless of original coxib therapy.

The Association between Emergency Department Crowding and Analgesia Administration in Acute Abdominal Pain Patients

ACADEMIC EMERGENCY MEDICINE, Issue 7 2009
Angela M. Mills MD
Abstract Objectives:, The authors assessed the effect of emergency department (ED) crowding on the nontreatment and delay in treatment for analgesia in patients who had acute abdominal pain. Methods:, This was a secondary analysis of prospectively enrolled nonpregnant adult patients presenting to an urban teaching ED with abdominal pain during a 9-month period. Each patient had four validated crowding measures assigned at triage. Main outcomes were the administration of and delays in time to analgesia. A delay was defined as waiting more than 1 hour for analgesia. Relative risk (RR) regression was used to test the effects of crowding on outcomes. Results:, A total of 976 abdominal pain patients (mean [±standard deviation] age = 41 [±16.6] years; 65% female, 62% black) were enrolled, of whom 649 (67%) received any analgesia. Of those treated, 457 (70%) experienced a delay in analgesia from triage, and 320 (49%) experienced a delay in analgesia after room placement. After adjusting for possible confounders of the ED administration of analgesia (age, sex, race, triage class, severe pain, final diagnosis of either abdominal pain not otherwise specified or gastroenteritis), increasing delays in time to analgesia from triage were independently associated with all four crowding measures, comparing the lowest to the highest quartile of crowding (total patient-care hours RR = 1.54, 95% confidence interval [CI] = 1.32 to 1.80; occupancy rate RR = 1.64, 95% CI = 1.42 to 1.91; inpatient number RR = 1.57, 95% CI = 1.36 to 1.81; and waiting room number RR = 1.53, 95% CI = 1.31 to 1.77). Crowding measures were not associated with the failure to treat with analgesia. Conclusions:, Emergency department crowding is associated with delays in analgesic treatment from the time of triage in patients presenting with acute abdominal pain. [source]


Emergency Department Sickle Cell Assessment of Needs and Strengths (ED-SCANS), a Focus Group and Decision Support Tool Development Project

ACADEMIC EMERGENCY MEDICINE, Issue 8 2010
Paula Tanabe PhD
ACADEMIC EMERGENCY MEDICINE 2010; 17:848,858 © 2010 by the Society for Academic Emergency Medicine Abstract Objectives:, A decision support tool may guide emergency clinicians in recognizing assessment, analgesic and overall management, and health service delivery needs for patients with sickle cell disease (SCD) in the emergency department (ED). We aimed to identify data and process elements important in making decisions regarding evaluation and management of adult patients in the ED with painful episodes of SCD. Methods:, Qualitative methods using a series of focus groups and grounded theory were used. Eligible participants included adult clients with SCD and emergency physicians and nurses with a minimum of 1 year of experience providing care to patients with SCD in the ED. Patients were recruited in conjunction with annual SCD meetings, and providers included clinicians who were and were not affiliated with sickle cell centers. Groups were conducted until saturation was reached and included a total of two patient groups, three physician groups, and two nurse groups. Focus groups were held in New York, Durham, Chicago, New Orleans, and Denver. Clinician participants were asked the following three questions to guide the discussion: 1) what information would be important to know about patients with SCD in the ED setting to effectively care for them and help you identify patient analgesic, treatment, and referral needs? 2) What treatment decisions would you make with this information? and 3) What characteristics would a decision support tool need to have to make it meaningful and useful? Client participants were asked the same questions with rewording to reflect what they believed providers should know to provide the best care and what they should do with the information. All focus groups were audiotaped and transcribed. The constant comparative method was used to analyze the data. Two coders independently coded participant responses and identified focal themes based on the key questions. An investigator and assistant independently reviewed the transcripts and met until the final coding structure was determined. Results:, Forty-seven individuals participated (14 persons with SCD, 16 physicians, and 17 nurses) in a total of seven different groups. Two major themes emerged: acute management and health care utilization. Major subthemes included the following: physiologic findings, diagnostics, assessment and treatment of acute painful episodes, and disposition. The most common minor subthemes that emerged included past medical history, presence of a medical home (physician or clinic), individualized analgesic treatment plan for treatment of painful episodes, history of present illness, medical home follow-up available, patient-reported analgesic treatment that works, and availability of analgesic prescription at discharge. Additional important elements in treatment of acute pain episodes included the use of a standard analgesic protocol, need for fluids and nonpharmacologic interventions, and the assessment of typicality of pain presentation. The patients' interpretation of the need for hospital admission also ranked high. Conclusions:, Participants identified several areas that are important in the assessment, management, and disposition decisions that may help guide best practices for SCD patients in the ED setting.

Emerging strategies for exploiting cannabinoid receptor agonists as medicines

BRITISH JOURNAL OF PHARMACOLOGY, Issue 3 2009
Roger G Pertwee
Mandarin translation of abstract Medicines that activate cannabinoid CB1 and CB2 receptor are already in the clinic. These are Cesamet® (nabilone), Marinol® (dronabinol; ,9 -tetrahydrocannabinol) and Sativex® (,9 -tetrahydrocannabinol with cannabidiol). The first two of these medicines can be prescribed to reduce chemotherapy-induced nausea and vomiting. Marinol® can also be prescribed to stimulate appetite, while Sativex® is prescribed for the symptomatic relief of neuropathic pain in adults with multiple sclerosis and as an adjunctive analgesic treatment for adult patients with advanced cancer. One challenge now is to identify additional therapeutic targets for cannabinoid receptor agonists, and a number of potential clinical applications for such agonists are mentioned in this review. A second challenge is to develop strategies that will improve the efficacy and/or the benefit-to-risk ratio of a cannabinoid receptor agonist. This review focuses on five strategies that have the potential to meet either or both of these objectives. These are strategies that involve: (i) targeting cannabinoid receptors located outside the blood-brain barrier; (ii) targeting cannabinoid receptors expressed by a particular tissue; (iii) targeting up-regulated cannabinoid receptors; (iv) targeting cannabinoid CB2 receptors; or (v) ,multi-targeting'. Preclinical data that justify additional research directed at evaluating the clinical importance of each of these strategies are also discussed. Mandarin translation of abstract [source]

Standardized protocols for analgesic administration may ameliorate this discrepancy. [source]


The National Trend in Quality of Emergency Department Pain Management for Long Bone Fractures

ACADEMIC EMERGENCY MEDICINE, Issue 2 2007
PA-C, Tamara S. Ritsema MPH
Background Despite national attention, there is little evidence that the quality of emergency department (ED) pain management is improving. Objectives To compare the quality of ED pain management before and after implementation of the Joint Commission on the Accreditation of Healthcare Organizations' standards in 2001. Methods The authors performed a retrospective cohort study by using the National Hospital Ambulatory Medical Care Survey from 1998,2003. Patients who presented to the ED with a long bone fracture (femur, humerus, tibia, fibula, radius, or ulna) were compared. The authors extracted data on patient, visit, and hospital characteristics. The primary outcomes were the proportion of patients who received assessment of pain severity and who received analgesic treatment. Results There were 2,064 patients with a qualifying fracture in the study period, 834 from 1998,2000 and 1,230 from 2001,2003. Compared with the early period, a higher proportion of patients in the late period had their pain assessed (74% vs. 57%), received opiates (56% vs. 50%), and received any analgesic (76% vs. 56%). Patients in the late period had higher odds of receiving any analgesia (adjusted odds ratio [OR], 1.43) and opioid analgesia (adjusted OR, 1.27) compared with the early period. Patients in the middle age group (adjusted OR, 2.28) or those seen by physician assistants (adjusted OR, 2.05) were more likely, whereas those with Medicaid (adjusted OR, 0.58) and those in the Northeast were less likely, to receive opiates. Conclusions Although the quality of ED pain management for acute fractures appears to be improving, there is still room for further improvement. [source]


Review article: new receptor targets for medical therapy in irritable bowel syndrome

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 1 2010
M. CAMILLERI
Summary Background, Despite setbacks to the approval of new medications for the treatment of irritable bowel syndrome, interim guidelines on endpoints for irritable bowel syndrome (IBS) trials have enhanced interest as new targets for medical therapy are proposed based on novel mechanisms or chemical entities. Aims, To review the approved lubiprostone, two targets that are not meeting expectations (tachykinins and corticotrophin-releasing hormone), the efficacy and safety of new 5-HT4 agonists, intestinal secretagogues (chloride channel activators, and guanylate cyclase-C agonists), bile acid modulation, anti-inflammatory agents and visceral analgesics. Methods, Review of selected articles based on PubMed search and clinically relevant information on mechanism of action, safety, pharmacodynamics and efficacy. Results, The spectrum of peripheral targets of medical therapy addresses chiefly the bowel dysfunction of IBS and these effects are associated with pain relief. The pivotal mechanisms responsible for the abdominal pain or visceral sensation in IBS are unknown. The new 5-HT4 agonists are more specific than older agents and show cardiovascular safety to date. Secretory agents have high specificity, low bioavailability and high efficacy. The potential risks of agents ,borrowed' from other indications (such as hyperlipidaemia, inflammatory bowel disease or somatic pain) deserve further study. Conclusions, There is reason for optimism in medical treatment of IBS with a spectrum of agents to treat bowel dysfunction. However, visceral analgesic treatments are still suboptimal. [source]
