Randomized Controlled Trial Clinical Trial
Epidural fentanyl does not influence intravenous PCA requirements in the post-caesarean patient.
Forty ASA physical status I or II patients scheduled for elective Caesarean delivery were studied to determine the effect of epidural fentanyl on post-Caesarean delivery analgesic requirements as administered by intravenous patient-controlled analgesia (PCA). Following delivery of the infant, under epidural anaesthesia with lidocaine 2% with 1/200,000 epinephrine, patients were randomly assigned to receive either 10 ml of preservative-free normal saline via the epidural catheter or 100 micrograms of fentanyl with 8 ml preservative-free normal saline in a double-blinded fashion. ⋯ No differences were observed in any values between the groups. It is concluded that a single bolus of epidural fentanyl does not provide an advantage for postoperative pain relief in this patient population.

Randomized Controlled Trial Clinical Trial
Use of intrathecally administered morphine in the treatment of postoperative pain after lumbar spinal surgery: a prospective, double-blind, placebo-controlled study.
Improved control of postoperative pain is now known to reduce the incidence of morbidity. Although spinally administered narcotics have found a clear role in chest and abdominal surgery, their role in lumbar spinal surgery is debated. We conducted a prospective, double-blind, randomized, placebo-controlled trial of intrathecally administered morphine sulfate after lumbar spinal surgery in 56 patients. ⋯ Consumption of parenteral narcotics on the first postoperative day and over the total hospitalization period decreased in correlation with increasing doses of intrathecally administered morphine. Mean length of hospitalization was significantly decreased, as compared with the control group, in patients receiving 0.25 or 0.5 mg of intrathecally administered morphine. When proper precautions are observed, intrathecally administered morphine can improve the postoperative care of patients undergoing lumbar spinal surgery.

Randomized Controlled Trial Clinical Trial
Wound infiltration of local anaesthetic after lower segment caesarean section.
The analgesic efficacy of subcutaneous wound infiltration with 20 ml of 0.5% bupivacaine after elective lower segment section Caesarean section was studied in 28 patients in a double-blind randomised controlled manner using a patient-controlled analgesia system. The mean 24-hour morphine consumption of the placebo group and the bupivacaine group was similar (76 mg and 68 mg respectively). ⋯ However, on a weight-adjusted basis statistically significant differences in morphine consumption were demonstrated, although these may not be clinically important. Subjective experiences of pain, nausea and drowsiness assessed by linear analogue scoring were similar in both groups.

Comparative StudyAnalgesia after cesarean delivery: patient evaluations and costs of five opioid techniques.
The study was designed to compare five opioid analgesic regimens administered after cesarean delivery in a routine hospital setting with respect to patients' perceptions of their pain relief and the impact of analgesic technique on recovery and hospital costs. After cesarean delivery, 684 patients received one of the following: epidural morphine, alone (EM,n = 128), or with fentanyl (EM + F,n = 245); subarachnoid morphine (n = 48); intramuscular meperidine (n = 165), or patient-controlled analgesia using meperidine (PCA, n = 98). On the first three postoperative days (Days 1-3; day of operation is Day 1) patients were surveyed regarding their impressions of their analgesia, the incidence of side effects, times to resume normal activities and satisfaction with their technique. ⋯ Other aspects of recovery did not differ among the groups. Satisfaction parallelled pain relief and was better with intraspinal than with systemic opioids. Costs were greatest with PCA, although differences were small (less than 1%) relative to total hospital charges.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of intravenous ketoprofen with pethidine for postoperative pain relief following nasal surgery.
A controlled investigation was conducted to compare the efficacy of ketoprofen and pethidine in relief of postoperative pain after nasal surgery. Sixty patients were randomly allocated to receive intravenous ketoprofen 1.5 mg.ml-1 or pethidine 1 mg.kg-1 during induction of anaesthesia. Appearance, pain and headache were assessed 1, 2, and 4 h postoperatively, and the following morning. ⋯ Patients who received ketoprofen had significantly lower pain and headache scores (P less than 0.01 and P less than 0.001, respectively), and required significantly (P less than 0.05) less postoperative analgesia. No significant difference in incidence and severity of postoperative nausea or vomiting was found between the two groups at any time. A single intravenous dose of ketoprofen during anaesthesia may offer an advantage compared to pethidine in reducing postoperative pain following nasal surgery.
