History of Changes

Purpose

Transversus abdominis plane (TAP) block has gained popularity for the control of postoperative pain in various surgeries. Three studies showed inconsistent result on pain control after TAP block in laparoscopic cholecystectomy. The TAP technique used in these studies was classic ultrasound guided TAP block. Besides periumbilical incision, sub-xiphoid incision is usually made during laparoscopic cholecystectomy. As typical posterior TAP rarely extend above T8, the investigators undergo subcostal TAP block for this type of surgery. The investigators are going to investigate the effect of subcostal TAP on early postoperative pain after laparoscopic cholecystectomy.

Estimated Enrollment:	50
Study Start Date:	July 2012
Estimated Study Completion Date:	March 2013
Estimated Primary Completion Date:	December 2012 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Placebo Comparator: Control Control group receiving saline instead of ropivacaine	Procedure: Placebo Ultrasound guided subcostal TAP block Under ultrasound guidance saline 10 ml will be injected between rectus abdominis and transverse abdominis and same study solution will be injected at subcostal transversus abdominis plane. This block will be done bilaterally.
Experimental: TAP TAP group receiving ropivacaine total of 150 mg at TAP under US	Procedure: Ultrasound guided subcostal TAP block Under ultrasound guidance0.375% ropivacaine 10 ml will be injected between rectus abdominis and transverse abdominis and same study solution will be injected at subcostal transversus abdominis plane. This block will be done bilaterally.
