Trial on TAP Block After Bariatric Surgery

Impact of Ultrasound-Guided Transversus Abdominis Plane Block on Postoperative Pain After Laparoscopic Bariatric Surgery: a Randomized Double Blind Controlled Trail

Summary

Patients undergoing bariatric surgery will be divided randomly into two groups: the first will have TAP block upon completion of surgery and the second groups will not have TAP block.

Detailed description

Upon completion of the laparoscopic bariatric procedure to be performed for every patient and just before recovery from general anesthesia, an ultrasound-guided TAP block will be conducted in the operative theater by the anesthetist for group I patients whereas group II will be recovered from anesthesia without having a TAP block. The ultrasound probe will be placed on the lateral abdominal wall in the mid-axillary line between the lower costal margin and iliac crest. Using ultrasound will allow accurate deposition of the local anesthetic in the correct neurovascular plane. A spinal needle will be advanced using in-plane technique between the aponeurosis of the internal oblique and transversus abdominis muscles. With intermittent aspiration, 20 mL of local anesthetic (0.25% bupivacaine) will be deposited in the TAP on each side and seen as a hypoechoic shadow pushing the two layers apart.
