Randomized Controlled Trial Clinical Trial[Continuous venous infusion of buprenorphine with autonomous elastomeric system in the control of postoperative pain].
We herein evaluated the analgesic effectiveness of low doses of buprenorphine with or without a primer and the practicality and usefulness of a constant flow disposable infusion set (Infusor Baxter 2 ml/h). Our series consists of 300 patients, seen between January 1992 and December 1993, randomly distributed in three groups of 100 patients each. All patients were informed before operation about the use of pain Visual Analogical Scale (VAS) and how the infusor works. ⋯ Group B and C patients showed blood pressure, heart rate and respiratory rate values significantly reduced compared to group A patients at T0 and T1. Such values however then stabilized. Side effects encountered were nausea and vomiting in different percentages in the three groups.(ABSTRACT TRUNCATED AT 250 WORDS)

[Effect of indomethacin as an adjunct to postoperative pain relief by continuous epidural infusion of bupivacaine and buprenorphine].
We examined the analgesic effects of indomethacin as an adjunct to postoperative epidural analgesia in 40 patients who underwent upper abdominal surgery. Twenty patients in control group were epidurally given 0.1 mg of buprenorphine in 8 ml of 0.25% bupivacaine immediately after surgery and subsequently infused 15 micrograms buprenorphine in 1 ml of 0.25% bupivacaine at a rate of 1 ml.h-1 for 48 h. ⋯ The patients who did not need additional narcotics in the control and indomethacin groups were 45% and 80%, respectively (P < 0.05). In upper abdominal surgery, postoperative pain relief by epidural buprenorphine and bupivacaine plus rectal indomethacin was more effective than that by epidural buprenorphine and bupivacaine.

Pain relief after caesarean section: comparison of different techniques of morphine administration.
We have studied postoperative pain relief after different techniques of morphine administration given in addition to bupivacaine 15 mg during spinal anaesthesia for caesarean section. In group A, morphine was given both intravenously (10 mg) and orally (30 mg slow release MST) at the end of surgery and continued orally at 8-hourly intervals for 24 h. ⋯ Pruritus was, on the other hand, observed in 48% of patients of group B compared to 7% of the patients of group A. This study suggests that adding 80 microg of morphine to the local anaesthetic used in spinal anaesthesia for caesarean section is a simple procedure that gives excellent results in term of reliability, duration of analgesia and safety.

Effect of preoperative skin infiltration with 0.5% bupivacaine on postoperative pain following cesarean section under spinal anesthesia.
Recent work suggests that preoperative skin infiltration with local anesthetic may lead to reduced postoperative pain. We have studied this in a randomised, prospective, double-blind trial of 40 women having cesarean section under spinal anesthesia. After establishment of the spinal block, the incision line was infiltrated in 20 women with 30 ml 0.5% bupivacaine and in 20 with 30 ml normal saline. There was no difference in pain scores between the 2 groups on any of the 3 postoperative days, perhaps due to the high quality analgesia provided by supplemental subarachnoid morphine.
