Purpose:

The purpose if to find out if analgesia with bilateral ultrasound-guided Tranversus Abdominis Plane (TAP) block with Ropivacaine 0.5% is better than analgesia with local infiltration of trochar sites with Ropivacaine 0.5% in patients undergoing laparoscopic cholecystectomy. Our hypothesis is that in laparoscopic cholecystectomy, bilateral TAP blocks will reduce postoperative pain scores when compared to conventional postoperative pain control with local infiltration of trochar insertion sites.
