Preincisional local infiltration of levobupivacaine vs ropivacaine for pain control after laparoscopic cholecystectomy.

Background: Postoperative pain is less intense after laparoscopic surgery than after open surgery. However, patients may gain additional benefit from a preincisional local infiltration of anesthetic. The aim of this study was to compare the analgesic efficacy of two local anesthetics, ropivacaine and levobupivacaine, for tissue infiltration as a means of improving postoperative pain control after laparoscopic cholecystectomy.

Preincisional intravenous low-dose ketamine and local infiltration with ropivacaine reduces postoperative pain after laparoscopic cholecystectomy.

Background: The preincisional use of ketamine combined with local tissue infiltration with Ropivacaine may reduce noxious input during surgery. The goal of this study was to examine whether this combination improves postoperative pain control after laparoscopic cholecystectomy.

Methods: A total of 55 patients were randomly assigned to one of three groups.
