Randomized Controlled Trial Comparative Study Clinical TrialInhibition of epidural morphine-induced pruritus by intravenous droperidol. The effect of increasing the doses of morphine and of droperidol.
Because the mechanism of inhibition of epidural morphine-induced pruritus by droperidol is not clear, this study was undertaken to determine the effects of larger doses of droperidol or morphine, or both. ⋯ Pruritus caused by epidural use of 2 or 4 mg of morphine is inhibited by the intravenous use of 2.5 mg droperidol but not by a larger dose.

Randomized Controlled Trial Comparative Study Clinical TrialCombined general and epidural anesthesia versus general anesthesia for major abdominal surgery: postanesthesia recovery characteristics.
Outcome studies comparing general anesthesia combined with epidural anesthesia (GEN-EPI) to general anesthesia (GEN) for major abdominal surgery have been equivocal. However, many believe that patients anesthetized with GEN-EPI fair better than GEN. This study tests the hypothesis that there are favorable recovery characteristics associated with GEN-EPI as compared with GEN following abdominal surgery. ⋯ Transient quantifiable differences in recovery characteristics exist between patients receiving GEN-EPI and GEN.

Randomized Controlled Trial Comparative Study Clinical TrialPain relief after knee arthroscopy: intra-articular morphine, intra-articular bupivacaine, or subcutaneous morphine?
This investigation was undertaken to compare analgesic effects, side effects, and requirements for supplemental analgesic therapy after knee arthroscopy in patients given intra-articular (IA) or subcutaneous (SC) morphine, intra-articular bupivacaine, or placebo. ⋯ A single 10-mg dose of morphine given either IA or SC provides better and longer-lasting postoperative pain relief after knee arthroscopy than 20 mL IA bupivacaine 0.5% with epinephrine.

Clinical TrialFailed axillary brachial plexus block techniques result in high plasma concentrations of mepivacaine.
Unintentional extrasheath injection causes failed axillary brachial plexus block. We wanted to find out if extrasheath injections produce higher plasma concentrations of local anesthetics compared to intrasheath injections. We also studied the incidence of extrasheath injection with radiographs. ⋯ Failed extrasheath injection of 50 mL 1.5% plain mepivacaine produces higher arterial plasma concentration in axillary brachial plexus block.

Case ReportsRemoval of a torn Racz catheter from lumbar epidural space.
Epidural adhesiolysis, described by Racz et al. (1) utilizing a double-contrast injection technique, provides an epidurogram that clearly delineates the area of adhesions and furnishes a means to perform lesion-specific lysis of adhesions utilizing a flexible wire-embedded catheter. ⋯ This case report illustrates a difficult situation with a sheared and retained epidural catheter which could not be removed utilizing the standard techniques but was successfully removed without any residual problems using arthroscopy forceps.
