Comparative Study of Ultrasound Guided Transversus Abdominis Plane Block Using Bupivacaine With and Without Hyaluronidase in Laparoscopic Bariatric Surgery

Abstract

Background: Transversus abdominis plane (TAP) block is atechnique of regional anesthesia, which reduces the pain derived from abdominal wall incisions, decreases general anesthesia requirements, and increases hemodynamic stability. Hyaluronidase is an enzyme considered as the "spreading factor", facilitating the spread of local anesthetic solutions. It has been shown to produce reliable blockade with better spread and therefore better quality of block when used with local anesthetics.
