Brief summary
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.
Interventions
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.
PROCEDUREPlacebo 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.
