Randomized Controlled Trial Comparative Study Clinical Trial
A randomized double-blind comparison of epidural versus intravenous fentanyl infusion for analgesia after thoracotomy.
This study compared epidural and intravenous fentanyl infusions for pain relief for the first 20 h after thoracotomy, in order to examine whether an thoracic epidural fentanyl infusion offers clinical advantage over an intravenous infusion. Forty patients were assigned randomly to receive either fentanyl epidurally and saline intravenously or fentanyl intravenously and saline epidurally in a double-blind fashion. ⋯ Respiratory function was better preserved and the incidence of nausea and sedation was less in the epidural group than in the intravenous group. In conclusion there appears to be a clinical advantage to the epidural infusion over the intravenous infusion of fentanyl for analgesia after thoracotomy.

Efficacy of therapeutic suggestions for improved postoperative recovery presented during general anesthesia.
There have been claims that the postoperative course of patients may be improved by presentation during general anesthesia of therapeutic suggestions which predict a rapid and comfortable postoperative recovery. This study evaluated the effectiveness of such therapeutic suggestions under double-blind and randomized conditions. A tape recording predicting a smooth recovery during a short postoperative stay without pain, nausea, or vomiting was played during anesthesia to about half the patients (N = 109), while the remaining, control patients were played a blank tape instead (N = 100). ⋯ There were no meaningful, significant differences in postoperative recovery of patients receiving therapeutic suggestions and controls. These negative results were not likely to be due to insensitivity of the assessments of recovery, as they showed meaningful interrelations among themselves and numerous differences in recovery following different types of surgery. Widespread utilization of therapeutic suggestions as a routine operating room procedure seems premature in the absence of adequate replication of previously published positive studies.

Case ReportsContinuous intrathecal fentanyl infusion for postoperative analgesia.
Following inadvertent dural puncture during epidural catheter placement, a 20 gauge polyethylene catheter was placed in the intrathecal space, and continuous spinal anesthesia with hyperbaric bupivacaine was administered intraoperatively to supplement general anesthesia. Following surgery, a continuous intrathecal fentanyl infusion (0.2 mcg/kg/hr) was administered to provide postoperative analgesia. The child was awake and comfortable throughout this time and required no supplemental analgesic agents. Although epidural catheters are still our preferred method of analgesia, intrathecal fentanyl infusion is one alternative when inadvertent dural puncture occurs.

Comparative Study[Continuous epidural perfusion of morphine and bupivacaine for post-thoracotomy analgesia. Comparison between thoracic and lumbar epidural analgesia].
Relief of postoperative pain and the incidence of side effects occurring after continuous epidural infusion of morphine and bupivacaine were evaluated in patients undergoing a thoracotomy. We also studied the relevance of a close proximity of the epidural catheter to the metameric segment were the pain originated. The study involves 17 patients divided into two groups. ⋯ The epidural perfusion was interrupted in only one patient of TG due to the presence of arterial hypotension. The association of narcotics and local anesthetics in continuous epidural perfusion was an excellent method for achieving pain relief with minimum side effects. We conclude that both thoracic and lumbar epidural routes are advisable for post-thoracotomy pain relief.

Ketamine for caudal analgesia in children: comparison with caudal bupivacaine.
Fifty children undergoing inguinal herniotomy were allocated randomly to three groups to receive a caudal injection of either 0.25% bupivacaine 1 ml kg-1 with or without ketamine 0.5 mg kg-1 or ketamine 0.5 mg kg-1 with normal saline 1 ml kg-1. There was no significant difference in quality of pain relief, postoperative behaviour or analgesic requirements between the ketamine group and the two other groups. The bupivacaine-ketamine mixture provided better analgesia than the bupivacaine solution alone. Side effects such as motor weakness or urinary retention were not observed in the ketamine group.
