Randomized Controlled Trial Clinical TrialEpidural morphine for postoperative analgesia: a double-blind study.
Postoperative analgesia and the side effects of epidurally injected morphine were investigated in a double-blind study. Following lumbar epidural anesthesia for orthopedic operations, 174 patients received, in a randomized, double-blind fashion, either 0.1 mg/kg of morphine epidurally, 0.1 mg/kg of morphine intramuscularly, or saline epidurally at the end of surgery. Following epidural morphine, postoperative pain was les frequent, less intense and of shorter duration, use of analgesics and sedative was less frequent; and the postoperative feeling of well-being rated better than after systemic morphine or epidural saline. ⋯ The results were age independent. Side effects following epidural morphine included pruritus and disturbances of micturition. Nausea, vomiting, fatigue, and headache were of comparable frequency in the three groups.

Clinical Trial Controlled Clinical TrialEpidurally administered morphine for postcesarean analgesia.
A double blind study was performed to evaluate analgesia from epidurally injected morphine sulfate in 30 mothers after cesarean section following similar regional anesthetics. When compared with a saline placebo and 2 milligrams of epidurally injected morphine, a 4.5 milligram epidurally administered morphine dose resulted in a highly significant reduction in the initial 24 hour parenterally administered narcotic requirement, p less than 0.001, and a significantly greater duration of analgesia after epidural injection, p less than 0.0003. ⋯ No significant side-effects were noted. Epidurally administered morphine appears promising as a potent analgesic approach of extended duration with potential advantages for early maternal mobilization, improved fetal maternal interaction and reduced fetal narcotic exposure in the breast fed infant.

Randomized Controlled Trial Comparative Study Clinical Trial
Controlled comparison of I.M. morphine and buprenorphine for analgesia after abdominal surgery.
In a double-blind randomized non-crossover trial 47 patients received either morphine or buprenorphine by regular i.m. injection for 24 h after abdominal surgery. The two drugs were equally effective as analgesics at the doses used. ⋯ The remainder of the buprenorphine group developed progressively slower respiration rates after 12 h. The results indicate that buprenorphine has a synergistic respiratory depressant effect with fentanyl and phenoperidine and may have a cumulative effect when given regularly on a 6-hourly regimen.

Clinical Trial Controlled Clinical Trial
[Peridural anesthesia and analgesia results in general surgery].
Anesthesia for major general surgery should involve the use of anesthetic techniques that might reduce the risk of intraoperative and postoperative complications. The combination of intraoperative epidural anesthesia with local anesthetics (EPA) and the use of epidural opiates for postoperative pain relief shows advantages over the application of pure general anesthesia and over postoperative systemic analgesia. Epidural opiates lead to better quality analgesia with a quicker onset and longer duration than systemical analgesics. ⋯ After epidural opiates no significant decrease could be seen. Intraoperative use of EPA has the advantages of better hemodynamic conditions and a blockade of the endocrine-metabolic response to surgery. Postoperative peridural opiates block the endocrine response as well: the serum levels of ADH and cortisol are lower than under systemic analgesia.

Randomized Controlled Trial Clinical TrialInfluence of epidural morphine on postoperative pain, endocrine-metabolic, and renal responses to surgery. A controlled study.
In order to assess the analgesic properties of epidural low-dose morphine and its possible influence on the adrenocortical, hyperglycemic, renal, electrolyte and leukocyte responses to surgery and nitrogen excretion, a double-blind randomized study was undertaken in 14 otherwise healthy patients admitted for hysterectomy under halothane, N2O/o2 anesthesia. Before induction of anesthesia, an epidural catheter was introduced into the lumbar epidural space. After induction of anesthesia, either morphine 4 mg in 10 ml saline or 10 ml saline was injected into the epidural space, according to the allocation. ⋯ Plasma concentration of cortisol and glucose, plasma-and urine electrolytes, 24-h creatinine and free-water clearances, diuresis, fluid balance, leukocyte count and nitrogen excretion differed insignificantly between groups. In conclusion, epidural low-dose morphine is a superior alternative to conventional postoperative pain treatment because of greater and longer lasting pain relief, without apparent side-effects. The measured endocrine-metabolic and renal response did not differ between groups, indicating that low-dose epidural morphine does not inhibit afferent neurogenic stimuli from the site of surgical trauma.
