Morbid Obesity, Laparoscopic Sleeve Gastrectomy, Transversus Abdominis Plane Block, Local Wound Infiltration, Bupivacine, Opioid Use
Conditions
Brief summary
The goal of this randomized controlled trial is to compare laparoscopic guided peri-wound Transversus Abdominis Plane Block and bupivacaine versus local wound infiltration effect on reducing post-op opioid use in Laparoscopic Sleeve gastrectomy. The main questions it aims to answer are: • Can laparoscopic guided peri-wound Transversus Abdominis Plane Block reduced post operative morphine usage when comparing with local wound port site infiltration. Participants will be randomize into 2 group * peri-wound Transversus Abdominis Plane Block * local wound port site infiltration
Interventions
PROCEDUREperi-wound Transversus Abdominis Plane Block
0.25% bupivacaine 20ml was injected using no24 needle into a plane between internal oblique muscle and transversus abdominis muscle around every wound 2 cm. from wound opening. The procedure was confirmed by laparoscopic vision and the injection was done before removal of laparoscopic port.
PROCEDURELocal wound infiltration
0.25% bupivacaine 20ml was injected using no24 needle into subcutaneous tissue after the abdominal sheet was sutured.
