Randomized Controlled Trial Clinical TrialAddition of clonidine to epidural morphine enhances postoperative analgesia after cesarean delivery.
The randomized, double-blind, dose-response study was designed to evaluate the effects of the addition of clonidine to epidural morphine on postoperative analgesia and side effects in patients undergoing cesarean delivery. ⋯ A low dose of clonidine such as 75 micrograms doubled the duration of analgesia produced by 2 mg of morphine and a dose of 150 micrograms further increased the duration of postoperative complete analgesia without increasing the incidence of side effects. The morphine requirements during the postoperative period (36 hours) was greatly reduced by the addition of clonidine to the analgesic epidural mixture.

Epidural analgesia with local anesthetics and opioids is one of the most effective methods for postoperative pain control. In critical patients it seems to improve outcome as well as pain control. This technique works better when started in the intraoperative time. ⋯ Nursing staff cooperates with the Acute Pain Service doctors and nurses who are on call on a 24 hour basis. Many perspective and retrospective studies showed a very low incidence of major side effects with epidurals. So we can consider it safe and effective even if we consider its invasiveness.

Comparison of fentanyl with clonidine as adjuvants for epidural analgesia with 0.125% bupivacaine in the first stage of labor: a preliminary report.
48 primiparae received epidural analgesia in labor with 10 ml of 0.125% bupivacaine with epinephrine 1:800 000, and then were divided in 4 equal groups (n = 12) to receive one of the following: 5 ml saline (B); 100 mug of fentanyl (BF); 150 microg of clonidine (BC); 75 microg of clonidine and 50 microg of fentanyl (BCF). All the patients had satisfactory analgesia. Onset was similar in the 4 groups but the duration of analgesia was significantly prolonged by the addition of either 100 microg of fentanyl or 150 microg of clonidine (respectively 89.8 min and 92.5 min vs 62.5 min) (P < 0.0001). ⋯ Only patients receiving fentanyl had pruritus. Both fentanyl and clonidine produced sedation, but both incidence and severity were greater with the mixture. No differences in neonatal outcome assessed by Apgar scores and NACS, were observed.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesic effects of intra-articular bupivacaine and morphine after arthroscopic cruciate ligament surgery.
Intra-articular administration of local anaesthetics such as bupivacaine can produce short-term postoperative analgesia in patients undergoing diagnostic arthroscopy or arthroscopic meniscectomy. A peripheral anti-nociceptive effect may also be induced by the administration of intra-articular opiates interacting with local opioid receptors in inflamed peripheral tissue. In the present study we aimed to study the analgesic effects of intra-articularly given bupivacaine and morphine sulphate (as well as the combination of both drugs) on postoperative pain. ⋯ In the group that received a combination of both bupivacaine and morphine, the pain scores were significantly reduced throughout the whole postoperative observation period. No side-effects or complications from therapy were seen in any of the groups. The conclusion of this study is that intra-articular morphine is effective in the postoperative period after arthroscopic ACL reconstruction.(ABSTRACT TRUNCATED AT 250 WORDS)
