    Postoperative analgesic requirements , total laparoscopic hysterectomy versus vaginal hysterectomy

    AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 2 2005
    Marcelo Carraro NASCIMENTO
    Abstract Background:, There is limited information available on the requirement for postoperative analgesic drugs in patients submitted to total laparoscopic hysterectomy (TLH) compared with patients undergoing vaginal hysterectomy (VH). Aim:, To compare the postoperative analgesic requirements in patients who underwent a TLH with patients who had a VH. Methods:, Chart review of 53 patients who had TLH and 47 who had VH and were seen postoperatively by an acute pain management service in order to assess postoperative analgesic requirements. Patient controlled analgesia (PCA) was part of the standard protocol for postoperative pain management. Analgesic requirement was recorded as the mean doses of morphine and number of days that patients used non-steroidal anti-inflammatory drugs (NSAIDs), oxycodone and tramadol. Results:, The requirement for total morphine was approximately half the dose in patients who had a TLH (10.8 ± 12.6 mg) compared with patients who had a VH (19.4 ± 21.9 mg) (P 0.017). The length of use of NSAIDs was significantly reduced in patients who had undergone a TLH (2.0 ± 0.95 days) as compared with patients who had a VH (2.85 ± 1.1 days) (P < 0.0001). Conclusions:, Patients submitted to TLH require less postoperative analgesic drugs when compared with patients who had VH. Prospective randomised trials are warranted to compare analgesic requirements between patients submitted to TLH and VH. [source]

    Comparison of transperitoneal and retroperitoneal laparoscopic nephrectomy for renal cell carcinoma: A single-center experience of 100 cases

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 11 2008
    Takatsugu Okegawa
    Objectives: To report our experience with the retroperitoneal and transperitoneal approaches of laparoscopic nephrectomy for renal cell carcinoma (RCC). Methods: Between July 2001 and December 2007, 100 patients with RCC underwent laparoscopic radical nephrectomy at our institution for clinically localized RCC. Fifty-three patients received a retroperitoneal procedure and 47 received a transperitoneal procedure. The perioperative and oncological outcomes of these groups were reviewed retrospectively. Results: Mean follow up was 34 months. No statistically significant difference was found between the two approaches in terms of pathological stage, operative time, need for additional procedures such as adrenalectomy and/or lymph node sampling, estimated blood loss, need for blood transfusions, analgesic requirement, length of hospital stay, or the incidence of minor or major complications. The 5-year disease-free survival rate was 90% for both the retroperitoneal and transperitoneal procedures. The 5-year overall survival rates were 98% and 96%, respectively. Therefore, no significant difference was observed in the long-term oncological outcome between the two groups. Conclusions: Tumor control and surgical morbidity in laparoscopic radical nephrectomy seem not to be significantly influenced by the approach. [source]

    Retroperitoneoscopic pre-transplant native kidney nephrectomy

    INTERNATIONAL JOURNAL OF UROLOGY, Issue 4 2006
    RAJIV GOEL
    Aims:, Laparoscopic nephrectomy has become a standardized procedure for removal of benign non-functioning kidneys. We present our experience of retroperitoneoscopic pre-transplant native kidneys nephrectomy. Methods:, Comparison of 40 patients who underwent retroperitoneoscopy with 40 open simple pre-transplant nephrectomy patients was done. Results:, Forty retroperitoneoscopic nephrectomies were done between June 2003 and April 2005. The mean operative time was similar in the two groups; however, the mean blood loss, postoperative analgesic requirement, complication rate, hospital stay and convalescence period were significantly less in the retroperitoneoscopic group. Conclusion:, Retroperitoneoscopic nephrectomy should be offered as the primary treatment modality to patients requiring pre-transplant native kidney nephrectomy, except in patients where it is contraindicated.

    Unilateral paravertebral block: an alternative to conventional spinal anaesthesia for inguinal hernia repair

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2010
    P. BHATTACHARYA
    Background: Inguinal herniorrhaphy can be successfully performed using general, regional or local anaesthesia. Paravertebral block (PVB) has been used for unilateral procedures such as thoracotomy, breast surgery, chest wall trauma, hernia repair or renal surgery. Methods: We compared unilateral lumbar PVB with conventional spinal anaesthesia (SA) in 60 consenting ASA I and II males aged 18,65 years, scheduled for unilateral inguinal hernia repair. Patients were randomly assigned into two groups, P (n=30) or S (n=30) to receive either PVB or SA, respectively. Two patients (7%) in group P had to be converted to general anaesthesia due to block failure. During surgery, patients of both groups received intravenous infusion of propofol titrated to light sedation. Results: The time to first post-operative analgesic requirement (primary outcome measure) as 342 ± 73 min in group P and 222 ± 22 min in group S (P<0.0001). Time to ambulation was 234 ± 111 min in group P and 361 ± 32 min in group S (P<0.0001). Urinary retention requiring catheterization were found in zero (0%) patients in group P compared with five (16%) in group S (P=0.024). Conclusion: It can be concluded that unilateral PVB is more efficacious than conventional SA in terms of prolonging post-operative analgesia and reducing morbidities in patients undergoing elective unilateral inguinal hernia repair.

    Continuous incisional infusion of local anesthetic in pediatric patients following open heart surgery

    PEDIATRIC ANESTHESIA, Issue 6 2009
    CHRISTOPHER F. TIROTTA MD MBA
    Summary Aim:, To determine the efficacy and safety of a continuous subcutaneous local anesthetic (LA) infusion in pediatric patients following open heart surgery. Background:, The use of a continuous LA infusion has been shown to be beneficial following adult cardiac surgery. To date there are no studies in the pediatric population. Methods/Materials:, Using a prospective, randomized, and double blind design, we compared LA, either 0.25% levobupivacaine or bupivacaine (Treatment Group) to saline (Placebo Group) delivered subcutaneously via a continuous infusion for 72 h after open heart surgery in 72 patients. Requirements for postoperative analgesics and pain scores were recorded for 72 h and plasma levels of local anesthetic were measured. Secondary outcomes measures included time to first oral intake, time to first bowel movement, time to urinary catheter removal, length of stay, requirements for antiemetics and additional sedation. Results:, Total morphine requirements over the first 24 h were less in the Treatment Group than the Placebo Group (0.05 mg·kg,1 vs 0.2 mg·kg,1, P = 0.007); this was true for all patient groups except those patients weighing less than 6.3 kg. The number of patients requiring no morphine was greater in the Treatment Group (7/35 vs 1/37, P = 0.02). The Treatment Group also received less midazolam, lorazepam, and ketorolac than the Placebo Group over 72 h due to the reduced clinical need for these agents in patients weighing less than 31 kg. There were no differences in secondary outcomes. Conclusions:, A continuous incisional infusion of LA reduced postoperative analgesic requirement and sedative use in pediatric patients undergoing a median sternotomy incision. Dosed at a maximum rate of 0.4 mg·kg,1·h,1, a continuous incisional infusion of LA is effective and safe for up to 72 h, with plasma levels of local anesthetic well below the toxic threshold.

    The efficacy of intravenous or peritonsillar infiltration of ketamine for postoperative pain relief in children following adenotonsillectomy,

    PEDIATRIC ANESTHESIA, Issue 3 2007
    DIDEM DAL MD
    Summary Background :,A few previous studies have suggested the efficacy of i.v. ketamine for postoperative pain relief in children after adenotonsillectomy, but none has investigated the efficacy of peritonsillar infiltration of ketamine in these children. Methods :,This randomized, placebo-controlled study evaluated the effects of peritonsillar infiltration of ketamine in children undergoing adenotonsillectomy. Ninety ASA I-II children were randomized three groups of 30 each. Group I received: 2 ml i.v. saline, group II received i.v. ketamine (0.5 mg·kg,1) and group III received a local peritonsillar infiltration of ketamine (0.5 mg·kg,1). All medications were 2 ml in volume which was applied 1 ml per tonsil 3 min prior to tonsillectomy. Modified Hannallah pain scale [observational pain scores (OPS)], nausea, vomiting, bleeding, rescue analgesia, sedation and Aldrete scores were recorded at first, 15th, 30th and 60th min postoperatively. Patients were interviewed on the day after surgery to assess the postoperative pain, nightmares, hallucinations, vomiting and bleeding. Results :,Group I had higher OPS scores than group II and group III. Group II and group III had comparable scores, which were not statistically significant (P > 0.05). Group II had higher sedation score at 15th min (P = 0.015). Thirty-two children, 19 of whom were in group I had rescue analgesia in postanesthesia care unit (P < 0.05) and the time to first analgesic requirement was significantly shorter in group I than the other groups (P = 0.006). Group II and group III also had less pain than group I at home (P = 0.023). Conclusions :,Low dose ketamine given i.v. or by peritonsillar infiltration perioperatively provides efficient pain relief without side-effects in children undergoing adenotonsillectomy. [source]

    Randomized clinical trial of laparoscopic versus open fundoplication for gastro-oesophageal reflux disease,

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2004
    R. Ackroyd
    Background: The aim of this study was to compare laparoscopic and open Nissen fundoplication for gastro-oesophageal reflux disease in a randomized clinical trial. Methods: Ninety-nine patients were randomized to either laparoscopic (52) or open (47) Nissen fundoplication. Patients with oesophageal dysmotility, those requiring a concurrent abdominal procedure and those who had undergone previous antireflux surgery were excluded. Independent assessment of dysphagia, heartburn and patients' satisfaction 1, 3, 6 and 12 months after surgery was performed using multiple standardized clinical grading systems. Objective measurement of oesophageal acid exposure and lower oesophageal sphincter pressure before and after surgery, and endoscopic assessment of postoperative anatomy, were performed. Results: Operating time was longer in the laparoscopic group (median 82 versus 46 min). Postoperative pain, analgesic requirement, time to solid food intake, hospital stay and recovery time were reduced in the laparoscopic group. Perioperative outcomes, postoperative dysphagia, relief of heartburn and overall satisfaction were equally good at all follow-up intervals. Reduction in oesophageal acid exposure, increase in lower oesophageal sphincter tone and improvement in endoscopic appearances were the same for the two groups. Conclusion: The laparoscopic approach to Nissen fundoplication improved early postoperative recovery, with an equally good outcome up to 12 months.

    Superficial selective cervical plexus block following total thyroidectomy: A randomized trial

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2010
    Isaak Kesisoglou MD
    Abstract Background. Pain after thyroid surgery is of moderate intensity and short duration. Bilaterally superficial cervical plexus block (BSCPB) may reduce analgesic requirements. However, its effectiveness in decreasing pain after thyroidectomy is debated. Methods. This double-blind, randomized placebo-controlled study in 100 patients undergoing total thyroidectomy evaluates the effects of BSCPB done with 20 mL of 0.75% ropivacaine. Additional parecoxib was administrated immediately postoperatively and 12 hours later. Results. Postoperative pain was assessed by visual analogue rating scale. All parameters were recorded at 0, 3, 6, 9, 12, and 24 hours after surgery. The control group had higher values than the ropivacaine group at all moments (p < .05) except H12 (p = .76). Additional analgesia was needed for 7 patients (14%) in the control group and for 8 patients (16%) in the group with ropivacaine (p = .96). Conclusion. Two-point bilateral BSCPB has a major analgesic effect on patients after total thyroidectomy, with a statistically significant reduction in postoperative pain scores. However, no significant difference was noted in the proportion of patients that required additional analgesics. © 2009 Wiley Periodicals, Inc. Head Neck, 2010 [source]

    Lidocaine vs. magnesium: effect on analgesia after a laparoscopic cholecystectomy

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 5 2010
    I. M. SAADAWY
    Background: This double-blinded study aimed at evaluating and comparing the effects of magnesium and lidocaine on pain, analgesic requirements, bowel function, and quality of sleep in patients undergoing a laparoscopic cholecystectomy (LC). Methods: Patients were randomized into three groups (n=40 each). Group M received magnesium sulfate 50 mg/kg intravenously (i.v.), followed by 25 mg/kg/h i.v., group L received lidocaine 2 mg/kg i.v., followed by 2 mg/kg/h i.v., and group P received saline i.v. Bolus doses were given over 15 min before induction of anesthesia, followed by an i.v. infusion through the end of surgery. Intraoperative fentanyl consumption and averaged end-tidal sevoflurane concentration were recorded. Abdominal and shoulder pain were evaluated up to 24 h using a visual analog scale (VAS). Morphine consumption was recorded at 2 and 24 h, together with quality of sleep and time of first flatus. Results: Lidocaine or magnesium reduced anesthetic requirements (P<0.01), pain scores (P<0.05), and morphine consumption (P<0.001) relative to the control group. Lidocaine resulted in lower morphine consumption at 2 h [4.9 ± 2.3 vs. 6.8 ± 2.8 (P<0.05)] and lower abdominal VAS scores compared with magnesium (1.8 ± 0.8 vs. 3.2 ± 0.9, 2.2 ± 1 vs. 3.6 ± 1.6, and 2.1 ± 1.4 vs. 3.3 ± 1.9) at 2, 6, and 12 h, respectively (P<0.05). Lidocaine was associated with earlier return of bowel function and magnesium was associated with better sleep quality (P<0.05). Conclusion: I.v. lidocaine and magnesium improved post-operative analgesia and reduced intraoperative and post-operative opioid requirements in patients undergoing LC. The improvement of quality of recovery might facilitate rapid hospital discharge. [source]

    Wound infiltration with magnesium sulphate and ropivacaine mixture reduces postoperative tramadol requirements after radical prostatectomy

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2009
    P. TAUZIN-FIN
    Purpose: This prospective, randomized, double-dummy study was undertaken to compare the effects of magnesium sulphate (MgSO4) administered by the intravenous vs. the infiltration route on postoperative pain and analgesic requirements. Methods: Forty ASA I or II men scheduled for radical retropubic prostatectomy under general anaesthesia were randomized into two groups (n=20 each). Two medication sets A and B were prepared at the pharmacy. Each set contained a minibag of 50 ml solution for IV infusion and a syringe of 45 ml for wound infiltration. Group MgSO4.IV patients received set A with 50 mg/kg MgSO4 in the minibag and 190 mg of ropivacaine in the syringe. Group MgSO4/L received set B with isotonic saline in the minibag and 190 mg of ropivacaine +750 mg of MgSO4 in the syringe. The IV infusion was performed over 30 min at induction of anaesthesia and the surgical wound infiltration was performed during closure. Pain was assessed every 4 h, using a 100-point visual analogue scale (VAS). Postoperative analgesia was standardized using IV paracetamol (1 g/6 h) and tramadol was administered via a patient-controlled analgesia system. The follow-up period was 24 h. Results: The total cumulative tramadol consumption was 221 ± 64.1 mg in group MgSO4.IV and 134 ± 74.9 mg in group MgSO4.L (P<0.01). VAS pain scores were equivalent in the two groups throughout the study. No side-effects, due to systemic or local MgSO4 administration, were observed. Conclusion: Co-administration of MgSO4 with ropivacaine for postoperative infiltration analgesia after radical retropubic prostatectomy produces a significant reduction in tramadol requirements.

    Intrathecal neostigmine with bupivacaine for infants undergoing lower abdominal and urogenital procedures: dose response

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2009
    Y. K. BATRA
    Background: Intrathecal (IT) neostigmine produces dose-dependent analgesia in adults. However, the dose of spinal neostigmine has not been investigated in infants. The purpose of this study was to assess spinal anesthesia (SA) duration provided by four doses of spinal neostigmine added to bupivacaine for lower abdominal and urogenital procedures in infants. Methods: Seventy-five infants were randomized into five groups. The control group B received IT plain 0.5% hyperbaric bupivacaine. Groups BN.25, BN.50, BN.75, and BN1.0 received bupivacaine with 0.25, 0.5, 0.75, and 1 ,g/kg of neostigmine, respectively. The primary variable was the duration of anesthesia assessed by recovery of hip flexion. Postoperative pain with facial expression, leg activity, arm activity, crying and consolability scale score,and rescue analgesic requirements were the secondary variables measured, and the side effects were noted. Results: Seventy-three infants completed the study. There was a significant linear increase in SA duration with IT neostigmine to 65.2 (4.3) min with 0.5 ,g/kg (P<0.01), 88.2 (5.1) with 0.75 ,g/kg (P<0.001) and 92 (4.3) with 1 ,g/kg (P<0.001) from 52.4 (4.3) min with bupivacaine alone. SA duration showed no significant difference between plain bupivacaine and BN.25 (P=0.100) or between groups BN.75 and BN1.0 (P=0.451). Groups BN.75 and BN1.0 had significantly reduced pain scores, and the median duration before the first dose rescue analgesic was requested prolonged significantly (P<0.001) compared with the other three groups. Conclusions: IT neostigmine at a dose of 0.75 ,g/kg added to bupivacaine significantly prolonged SA duration with reduced postoperative pain scores and rescue analgesic requirements in infants undergoing lower abdominal and urogenital procedures. No additional benefits were provided on increasing it to 1 ,g/kg. [source]

    Comparison of the effect of ketamine added to bupivacaine and ropivacaine, on stress hormone levels and the duration of caudal analgesia

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 10 2005
    M. Akbas
    Background:, The aim of this study was to compare bupivacaine 0.25% and ropivacaine 0.2%, singly and in combination with ketamine, for caudal administration in children. Duration of analgesia, the need for other analgesics and the stress response were measured. Methods:, Eighty children were ramdomized into four groups of twenty. The bupivacaine group received bupivacaine 0.25% and the ketamine/bupivacaine group received bupivacaine 0.25% plus 0.5 mg/kg ketamine. The ropivacaine group received ropivacaine 0.2%, and the ketamine/ropivacaine group received ropivacaine 0.2% plus 0.5 mg/kg ketamine. The duration of analgesia and analgesic requirements were recorded for each group, as were peri-operative and post-operative concentrations of the stress hormones insulin, glucose and cortisol. Results:, Ketamine, added to either bupivacaine or ropivacaine for caudal analgesia, gave a longer duration of analgesia (P < 0.05) than bupivacaine or ropivacaine alone. In all groups, blood insulin concentration was increased, and cortisol concentration reduced. Glucose concentration was significantly increased in all groups (P < 0.05). Conclusions:, Ketamine can safely be added to ropivacaine 0.2% or bupivacaine 0.25% for caudal anesthesia in order to prolong duration of analgesia and reduce the need for additional analgesics. Stress hormone levels are partially attenuated. [source]

    Preoperative ropivacaine infiltration in breast surgery

    ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2000
    A. Johansson
    Purpose: The aim of the study was to investigate whether preoperative infiltration with ropivacaine in conjunction with breast surgery improves postoperative pain management and attenuates postoperative nausea and vomiting. Method: Prospective, randomised, double-blind study, including 60 healthy women (ASA 1,2) allocated to one of two groups. Thirty patients were given 0.3 ml/kg saline in the operating field before surgery. Another 30 patients received a similar volume of ropivacaine 3.75 mg/ml. A visual analogue scale (0,100 mm) was used for evaluation of postoperative pain, nausea and vomiting. If the score was more than 30 mm at rest, the patients were given ketobemidone i.v. as treatment for postoperative pain, and dixyrazine i.v. against nausea and vomiting. The intra- and postoperative analgesic requirements and postoperative nausea and vomiting were registered. Results: The intraoperative fentanyl consumption was similar in the saline group 81±22 ,g vs 76±28 ,g; (ns) in the ropivacaine group. The postoperative 24-h ketobemidone consumption was also similar to those treated with ropivacaine (4.2±2.6 mg vs 4.2±4.3 mg; ns). Postoperative nausea and vomiting (PONV) occurred with similar frequencies in both groups. The 24-h dixyrazine consumption was the same in the two groups (2.1±2.7 mg in the saline group compared to 2.4±2.8 mg in the ropivacaine group; ns). After 6 h recovery, 41% of all patients had experienced nausea and 20% vomiting. Conclusion: We found no differences in postoperative pain management between 3.75 mg/ml ropivacaine and saline wound infiltration before breast surgery. The data show similar postoperative needs of analgesics and antiemetics with a similar frequency of PONV. [source]

    The Effect of Preemptive Analgesia in Postoperative Pain Relief,A Prospective Double-Blind Randomized Study

    PAIN MEDICINE, Issue 1 2009
    Seetharaman Hariharan MD
    ABSTRACT Objective., To analyze the effect of infiltration of local anesthetics on postoperative pain relief. Design., Prospective randomized double-blind trial. Setting., University Teaching Hospital in Barbados, West Indies. Patients., Patients undergoing total abdominal hysterectomy. Interventions., Patients were randomly allocated into one of four groups according to the wound infiltration: 1) preoperative and postoperative 0.9% saline; 2) preoperative saline and postoperative local anesthetic mixture (10 mL 2% lidocaine added to 10 mL 0.5% bupivacaine); 3) preoperative local anesthetic mixture and postoperative saline; and 4) preoperative and postoperative local anesthetic mixture. Both patients and investigators were blinded to the group allocation. All patients received pre-incision tenoxicam and morphine, standardized anesthesia, and postoperative morphine by patient-controlled analgesia. Outcome measures., The amount of morphine used and the intensity of pain as measured by visual analog pain scale were recorded at 1, 2, 3, 4, 8, 12, 24, and 48 hours postoperatively. Results., Eighty patients were studied with 20 in each group. Total dose of morphine used by patients who received preoperative and postoperative local anesthetic infiltration was lesser compared to other groups, although there was no statistically significant difference. Similarly, there was no difference in the intensity of pain between any groups. Conclusions., Local anesthetic infiltration before and/or after abdominal hysterectomy does not reduce the intensity of postoperative pain and analgesic requirements. [source]

    Efficacy of bupivacaine-neostigmine and bupivacaine-tramadol in caudal block in pediatric inguinal herniorrhaphy

    PEDIATRIC ANESTHESIA, Issue 9 2010
    REZA TAHERI MD
    Summary Background:, Limited duration of analgesia is among the limitations of single caudal injection with local anesthetics. Therefore, the purpose of this study was to evaluate the effectiveness and safety of bupivacaine in combination with either neostigmine or tramadol for caudal block in children undergoing inguinal herniorrhaphy. Methods:, In a double-blinded randomized trial, sixty children undergoing inguinal herniorrhaphy were enrolled to receive a caudal block with either 0.25% bupivacaine (1 ml·kg,1) with neostigmine (2 ,g·kg,1) (group BN) or tramadol (1 mg·kg,1) (group BT). Hemodynamic variables, pain and sedation scores, additional analgesic requirements, and side effects were compared between two groups. Results:, Duration of analgesia was longer in group BT (17.30 ± 8.24 h) compared with group BN (13.98 ± 10.03 h) (P = 0.03). Total consumption of rescue analgesic was significantly lower in group BT compared with group BN (P = 0.04). There were no significant differences in heart rate, mean arterial pressure, and oxygen saturation between groups. Adverse effects excluding the vomiting were not observed in any patients. Conclusion:, In conclusion, tramadol (1 mg·kg,1) compared with neostigmine (2 ,g·kg,1) might provide both prolonged duration of analgesia and extended time to first analgesic in caudal block.

    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.

    Tramadol for pain relief in children undergoing tonsillectomy: a comparison with morphine

    PEDIATRIC ANESTHESIA, Issue 3 2003
    Thomas Engelhardt MD
    SummaryBackground: Pain control for paediatric patients undergoing tonsillectomy remains problematic. Tramadol is reported to be an effective analgesic and to have a side-effect profile similar to morphine, but is currently not licensed for paediatric use in the UK. Methods: We conducted a prospective, double-blind, randomized controlled trial in children who were scheduled for elective tonsillectomy or adenotonsillectomy at the Royal Aberdeen Children Hospital. Following local ethics committee approval and after obtaining a drug exemption certificate from the Medicines Licensing Agency for an unlicensed drug, we recruited 20 patients each into morphine (0.1 mg·kg,1), tramadol (1 mg·kg,1) and tramadol (2 mg·kg,1) groups. These drugs were given as a single injection following induction of anaesthesia. In addition, all patients received diclofenac (1 mg·kg,1) rectally. The postoperative pain scores, analgesic requirements, sedation scores, signs of respiratory depression and nausea and vomiting, as well as antiemetic requirements, were noted at 4-h intervals until discharge. Results: There were no statistically significant differences in age, weight, type of operation or induction of anaesthesia, 4-h sedation and pain scores and further analgesic requirements. There were no episodes of respiratory depression. Morphine was associated with a significantly higher incidence of vomiting following discharge to the wards (75% versus 40%, P=0.03) compared with both tramadol groups. Conclusions: Tramadol has similar analgesic properties, when compared with morphine. The various pharmaceutical presentations and the availability as a noncontrolled substance may make it a useful addition to paediatric anaesthesia if it becomes licensed for paediatric anaesthesia in the UK.

    Analgesia for paediatric tonsillectomy and adenoidectomy with intramuscular clonidine

    PEDIATRIC ANESTHESIA, Issue 7 2002
    Katherine O. Freeman MD
    SummaryBackground: After undergoing tonsillectomy and adenoidectomy (T&A), children may experience significant pain. Clonidine, an ,2 agonist, exhibits significant analgesic properties. The current investigation sought to determine whether intramuscular (I.M.) clonidine would decrease pain in paediatric patients undergoing T&A. Methods: Thirty-nine children undergoing elective T&A were studied. Following inhalational anaesthetic induction, fentanyl (2 ,g·kg,1) was given intravenously, acetaminophen (paracetamol) (30 mg·kg,1) was given rectally and the children then randomly received an i.m. injection of either normal saline or clonidine (2,g·kg,1). Perioperative analgesic requirements in the postanaesthesia care unit and at home following hospital discharge were evaluated. Results: There were no significant demographic, analgesic consumption, haemodynamic or pain score differences between the groups. Conclusions: We do not recommend adding i.m. clonidine (2 ,g·kg,1) to the analgesic regimen of children undergoing tonsillectomy and adenoidectomy. [source]

    Analgesia for circumcision in a paediatric population: comparison of caudal bupivacaine alone with bupivacaine plus two doses of clonidine

    PEDIATRIC ANESTHESIA, Issue 6 2001

    Background:,Clonidine is often used to improve the duration and quality of analgesia produced by caudal epidural blockade, although the optimum dose of clonidine with bupivacaine remains uncertain. Methods:,We compared the effect of clonidine, 1 and 2 ,g·kg,1, added to bupivacaine (1.25 mg·kg,1) with that of bupivacaine alone in 75 male children undergoing elective circumcision. Results:,There was a trend towards increasing duration of analgesia with increasing dose of clonidine [group B (bupivacaine) 280.7 (171.6) min, C1 (bupivacaine + clonidine 1 ,g·kg,1) 327.8 (188.3) min and C2 (bupivacaine + clonidine 2 ,g·kg,1) 382.0 (200.6) min], although this difference was not statistically significant. Mean time to arousal from anaesthesia was significantly prolonged with clonidine 2 ,g kg,1 (group C2 21.3 (13,36) min, group C1 14.0 (6,25) min and group B 14.4 (2,32) min. Supplementary analgesic requirements and incidence of adverse effects were low, with no differences between the groups. Conclusions:,For paediatric circumcision, under general anaesthesia, the addition of clonidine 2 ,g·kg,1 to low volume (0.5 ml·kg,1) caudal anaesthetics has a limited clinical benefit for children undergoing circumcision.

    Abstract Introduction: Laparoscopic adrenalectomy is recognized as a safe and feasible surgical procedure for removing adrenal masses, though some reports have questioned its use because of an increased risk of cardiovascular complications. This study aims to compare laparoscopic surgery and open surgery for pheochromocytoma. Methods: We analyzed 26 patients operated on for adrenal pheochromocytoma (laparoscopic surgery: 11 patients; open surgery: 15 patients) at Kyorin University Hospital from April 1995 to July 2009. Patient records were analyzed with regards to operative time, blood loss, complications, blood pressure during surgery, amount of analgesia required in patient-controlled analgesia, time to oral intake, length of hospital stay, and other factors. Results: Mean tumor size was greater in the open surgery patients. Blood loss was significantly less extensive in the laparoscopic surgery patients. Rates of intraoperative hypertension (defined as a sudden rise in systolic blood pressure of >200 mmHg) and hypotension (systolic blood pressure of <80 mmHg) immediately after clamping of the adrenal vein were significantly lower in the laparoscopic surgery patients. No significant differences were found between the two groups with respect to operative time, occurrence of complications, and analgesic requirements. Only one case (9.1%) required conversion from laparoscopic to open surgery because intraoperative complications, specifically uncontrollable hemorrhaging. Time to oral intake after surgery and hospital stay were significantly shorter in the laparoscopic surgery patients. During the follow-up period, there was no mortability or recurrence of endocrinopathy in the two groups. Conclusion: We consider the safety of laparoscopic adrenalectomy for pheochromocytoma to be similar to that of open surgery. [source]

    Aim:, The study aimed to compare the effect of intrauterine bupivacaine and levobupivacaine with placebo in reducing the post-procedure discomfort owing to pain caused by suction endometrial sampling. Methods:, This study was conducted on randomly selected 45 women with abnormal uterine bleeding and who had undergone outpatient hysteroscopy and endometrial biopsy under sedation with propofol 0.5 mg/kg. The study was performed using 5 mL of bupivacaine 0.5% (Group B, n = 15) or levobupivacaine 0.5% (Group L, n = 15) or placebo solution (Group C, n = 15) intrauterine via a catheter over a 5 min period after suction endometrial sampling. The number of patients with visual analogue scale >3, total postoperative analgesic requirements, satisfaction of patients and adverse events were measured. Nonparametric and parametric data were analysed using Kruskal,Wallis and one-way anova tests respectively. Results:, Women in Groups L and B had statistically significantly less pain than the women in Group C (P = 0.03). When compared with placebo, five ml of bupivacaine 0.5% and levobupivacaine 0.5% respectively were recorded to decrease the incidence of postoperative analgesic consumption from 41 to 35% (P = 0.01). The satisfaction score of the patients in Group L was significantly higher than that of the patients in Group C (P = 0.03). Conclusion:, Intrauterine levobupivacaine or bupivacaine is effective in decreasing the pain associated with the endometrial biopsy and curettage under propofol sedation. [source]

    Abstract Background:, There is limited information available on the requirement for postoperative analgesic drugs in patients submitted to total laparoscopic hysterectomy (TLH) compared with patients undergoing vaginal hysterectomy (VH). Aim:, To compare the postoperative analgesic requirements in patients who underwent a TLH with patients who had a VH. Methods:, Chart review of 53 patients who had TLH and 47 who had VH and were seen postoperatively by an acute pain management service in order to assess postoperative analgesic requirements. Patient controlled analgesia (PCA) was part of the standard protocol for postoperative pain management. Analgesic requirement was recorded as the mean doses of morphine and number of days that patients used non-steroidal anti-inflammatory drugs (NSAIDs), oxycodone and tramadol. Results:, The requirement for total morphine was approximately half the dose in patients who had a TLH (10.8 ± 12.6 mg) compared with patients who had a VH (19.4 ± 21.9 mg) (P 0.017). The length of use of NSAIDs was significantly reduced in patients who had undergone a TLH (2.0 ± 0.95 days) as compared with patients who had a VH (2.85 ± 1.1 days) (P < 0.0001). Conclusions:, Patients submitted to TLH require less postoperative analgesic drugs when compared with patients who had VH. Prospective randomised trials are warranted to compare analgesic requirements between patients submitted to TLH and VH. [source]

    Co-Administration of Dextromethorphan and Morphine: Reduction of Post-Operative Pain and Lack of Influence on Morphine Metabolism

    In a double-blind study, 60 patients with ASA physical status I,II were randomised into two groups. Group dextromethorphan (n = 30; age: 15.9 ± 2.4 years) was given oral dextromethorphan 30 or 45 mg 1 hr before surgery and 8, 20 and 32 hr after operation. Group placebo (n = 30; age: 16.5 ± 2.7 years) received placebo at identical times. Post-operative analgesic requirements were assessed using nurse-controlled analgesia system. Pain was assessed using numeric rating scale before first administration of morphine and at 2, 3, 4, 6, 24 and 48 hr after operation. Blood samples were taken 20 min. after the first use of morphine (within 1 hr after operation). The total use of analgesics during surgery was lower in the dextromethorphan group. The dose of morphine providing relief immediately after surgery, as well as total analgesic requirements in the first and second day after surgery did not differ between groups. Subjectively evaluated pain intensity score (numeric rating scale) was lower for the dextromethorphan patients in the first 4 hr, but not later after surgery. Plasma levels of morphine, morphine-6-glucuronide and morphine-3-glucuronide did not differ between groups. Dextromethorphan did not influence morphine glucuronidation, in terms of promotion of formation of any morphine glucuronides. In conclusion, in young patients subjected to spine surgery, addition of dextromethorphan to morphine reduced pain only in early post-operative period. In such patients, co-analgesic action of dextromethorphan was not associated with significant changes in plasma levels of morphine metabolites. [source]

    Laparoscopic live-donor nephrectomy: modifications for developing nations

    BJU INTERNATIONAL, Issue 9 2004

    Authors from Lucknow describe their experience with laparoscopic live-donor nephrectomy, and describe modifications they have used to make the procedure cost-effective for developing nations. As the urological world is increasingly realising, this approach to renal transplantation is increasing the number of live-donor kidneys being offered for the many patients with end-stage renal failure. In this considerable series, the authors are strongly of the opinion that this is the best approach to live donor nephrectomy, and that their modifications are helpful in its use in developing nations. OBJECTIVE To describe modifications to laparoscopic live-donor nephrectomy (LLDN) to make it more cost-effective for developing countries; LLDN was developed as a better alternative to conventional donor nephrectomy, with advantages of an earlier return to normal activities and smaller scars, but is not popular in developing countries because of high cost of disposable items. PATIENTS AND METHODS From January 2000 to January 2002, 148 LLDNs were performed, of which two used a hand-assisted technique, 17 the standard technique, 79 a modified laparoscopically assisted cost-saving approach and 50 by the modified technique. In the latter approach the kidney was delivered through a 6,8 cm anterior subcostal flank incision. In last 50 patients we further modified the technique, clipping the hilum using endoclips and delivering the kidney by holding the lateral pararenal fat through a 5 cm iliac fossa incision. RESULTS The mean age, operative duration, warm ischaemia time, blood loss, analgesic requirements, pain score and hospital stay were comparable among the various techniques used. Re-exploration was required in four patients (bleeding in two, trocar-induced bowel injury in two). Immediate complications after surgery occurred in 20% of patients. Using endoclips, the cost was considerably reduced, from $400 to $290. The iliac fossa incision was aesthetically pleasing and more acceptable to patients. CONCLUSION These modifications are relevant in the context of a developing nation, as they provide all the benefits of LLDN at reduced cost and with better cosmetic results. [source]

    Randomized clinical trial of single-incision laparoscopic cholecystectomy versus minilaparoscopic cholecystectomy

    Background: Transumbilical single-incision laparoscopic cholecystectomy (SILC) and minilaparoscopic cholecystectomy (MLC) are both increasingly being used to treat symptomatic gallstones. The present study compared SILC and MLC with respect to outcome in a prospective randomized trial. Methods: Seventy patients with symptomatic cholelithiasis were randomized to SILC or MLC (35 in each group). The primary outcome measure was postoperative pain. Secondary outcomes were duration of operation, complications, postoperative analgesic requirements, length of hospital stay, cosmetic result, wound length and time to return to work. Results: Surgical complications, postoperative pain scores, analgesic requirements and time to return to work were similar for both procedures. Statistically significant advantages of SILC were a shorter hospital stay, shorter total wound length and better cosmetic appearance. Duration of operation was significantly shorter for MLC. Conclusion: SILC is superior to MLC in terms of cosmetic outcome, but not in postoperative pain and requirement for analgesics. Copyright © 2010 British Journal of Surgery Society Ltd.

    Randomized clinical trial of haemorrhoidectomy under a mixture of local anaesthesia versus general anaesthesia

    BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2000
    K. S. Ho
    Background: Application of a topical anaesthetic agent may facilitate infiltration of local anaesthetic at haemorrhoidectomy. Methods: A randomized clinical trial of 53 consecutive patients requiring elective haemorrhoidectomy was carried out. One group underwent haemorrhoidectomy under general anaesthesia, while the second group had topical anaesthetic cream (containing lignocaine and prilocaine) applied followed by local anaesthetic infiltration for surgical anaesthesia. Results: There were no differences between the two groups in terms of operating time, postoperative pain, nausea or vomiting, pain-free interval after operation, analgesic requirements or patients' satisfaction with the method of anaesthesia. Postoperative oxygen saturation and pulse rate were similar in the two groups. Conclusion: Topical anaesthetic and local anaesthesia can be used effectively for haemorrhoidectomy and provide an alternative to general anaesthesia. © 2000 British Journal of Surgery Society Ltd [source]
