Laparoscopic TAP Block for Sleeve Gastrectomy: Does Timing Matter
Sponsor: Arthur Carlin
Summary
The goal of this study is to investigate whether an early intraoperative transverse abdominis plane block (TAP block) will provide superior analgesia to a late intraoperative TAP block. A fixed amount of bupivacaine will be used for the TAP block and the primary outcomes will be measured by patient reported numerical assessment scores for pain.

Interventions
TAP block
An 18-gauge needle will be introduced externally at the center of the mid axillary line between the lower costal margin and the iliac crest until the surgeon feels a "pop," after which the surgeon will inject the first 2 mL of 0.25% bupivicaine to verify the correct position. Doyle's internal bulge sign (the bulge seen when the transversus abdominis muscle and peritoneum is pushed internally) will be visualized and the remainder of the 60 mL of 0.25% bupivacaine will be injected. The contralateral block will be performed according to the same technique but with only 30 ml of bupivicaine.
