[Effects of sevoflurane on mid-latency auditory evoked potentials and the 95% spectral frequency limit].

Objectives: To investigate the effects of sevoflurane on mid-latency auditory evoked potentials (MLAEP) and compare them to changes in the encephalographic 95% spectral edge frequency (SEF95).

Patients And Methods: The effect of sevoflurane on MLAEP and SEF95 was studied in 15 patients. Anesthetic induction was carried out with propofol, remifentanil, and cisatracurium.

Intraperitoneal application of bupivacaine plus morphine for pain relief after laparoscopic cholecystectomy.

Background And Objective: Intraperitoneal administration of a local anaesthetic in combination with an opioid, for the relief of postoperative pain, has already been reported except after laparoscopic cholecystectomy. This study was aimed at assessing the analgesic effect of the intraperitoneal administration of bupivacaine and morphine in patients undergoing laparoscopic cholecystectomy.

Methods: At the end of laparoscopic cholecystectomy, in a double-blind, randomized manner, one of the following injections was given intraperitoneally.
