Randomized Controlled Trial
Preoperative vs. postoperative bilateral paravertebral blocks for laparoscopic cholecystectomy: a prospective randomized clinical trial.
The aim of this clinical trial was to determine the potential analgesic effect of preoperative paravertebral blockade in patients undergoing laparoscopic cholecystectomy. ⋯ Bilateral paravertebral blockade performed prior to general anesthesia for laparoscopic cholecystectomy can provide early discharge and better postoperative pain management.
