Efficacy of Transversus Abdominis Plane (TAP) Block Techniques: A Comparison Between Intraoperative Surgeon Administration by Direct Visualization vs Image Guided Administration by Anesthesiologist, a Prospective Randomized Controlled Trial

Status: Completed

Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable

The transversus abdominis plane (TAP) block is a regional anesthesia technique where local anesthetic is injected into the neurovascular plane between the transversus abdominis and internal oblique muscles. The TAP block has been shown to provide postoperative analgesia following abdominal surgery.There are many methods to administer local anesthetic into the transversus abdominus plane to provide post-operative analgesia. The more prevalent method is for an anesthesia provider to inject local anesthetic into the plane using ultrasound guidance, before surgery or after the conclusion of surgery. Alternatively, a surgeon can administer the local anesthetic during the operation without additional time or expense using direct laparoscopic visualization. We propose to compare the two methods for non-inferiority, in the context of an established enhanced recovery after surgery (ERAS) program. Non-inferiority being established by no demonstrable difference in post-operative narcotic requirements and equivalent average pain scores.

Time Frame
Start Date: August 17, 2015
Completion Date: July 31, 2018
Target number of participants: 60
Active Comparator: TAP block administered by Surgery
transversus abdominis (TAP) plane block is performed by the surgeon at the conclusion of the surgery, still under general anesthesia, prior to removing the trocars a single dose 60 cc of 0.5%bupivicaine is delivered into the TAP under direct surgeon observed laparoscopic visualization. (Split dose 30cc/side)
Active Comparator: TAP block administered by Anesthesia
transversus abdominis (TAP) plane block is performed by the anesthesiologist at the conclusion of the surgery after incisions are closed and dressing are on, prior to emergence from general anesthesia, a single dose 60 cc of 0.5%bupivicaine is delivered into the TAP under by the anesthesiologist using ultrasound visualization. (Split dose 30cc/side)
