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.

Clinical TrialExtended unilateral anesthesia. New technique or paravertebral anesthesia?
The authors previously reported a case in which injection of local anesthetic posterior to the endothoracic fascia at the T11 vertebral level gave rise to extended analgesia in thoracic and lumbar dermatomes. They now report a study in which this type of anesthesia was used in patients undergoing herniorrhaphy. ⋯ Injection of local anesthetic posterior to the endothoracic fascia resulted in extended unilateral anesthesia that was adequate for herniorrhaphy in 9 of the 15 patients (60%) studied.
