TAP Block With Liposomal Bupivacaine Versus Pre-incisional Wound Infiltration With Bupivacaine for Postoperative Pain

Phase 1

Conditions
Postoperative Pain
Interventions
Procedure: Pre-incisional wound infiltration
Procedure: Laparoscope to place TAP block with liposomal bupivacaine
Registration Number
NCT02400645
Lead Sponsor
University of Tennessee
Brief Summary

In this randomized, controlled, double-blinded trial we plan to evaluate post-operative pain relief after laparoscopic-assisted Transversus Abdominis Plane (TAP) block using liposomal bupivacaine plus bupivacaine versus pre-incisional would infiltration with bupivacaine in patients undergoing Total laparoscopic or robotic assisted laparoscopic hysterectomy.

Detailed Description

Patients undergoing laparoscopic or robotic assisted total hysterectomy at Erlanger Hospital will be randomized into one of two groups to receive either laparoscopic assisted TAP block with liposomal bupivacaine and bupivacaine (Group A) or pre-incisional bupivacaine (Group B). The remaining aspects of the perioperative care, including the general anesthesia care and postoperative care will be similar for all patients. Ideally, patients will be informed and consented for the study in the preoperative clinic setting. They will be randomized in the pre-anesthesia care unit.

Patients in Group A will receive laparoscopic-assisted bilateral TAP blocks using 10cc liposomal bupivacaine, 10cc Bupivacaine 0.25% and 10cc Normal Saline one each side. Patients in Group B will receive a total of 20cc pre-incisional Bupivacaine divided between each of the trocar sites. All patients will receive Ketorolac 30 mg, IV at the conclusion of surgery. All patients will be offered either oral pain medications or patient controlled anesthesia (PCA) opiate pain medication as indicated. Morphine equivalents will be calculated.

Postoperative pain control will be assessed using Visual Analog Pain Score (VAS). This will be done by recovery room personnel who will be blinded as to whether the patients received TAP block or pre-incisional anesthetic. VAS will be assessed at rest at 1 hour and 2 hours after arrival to PACU. Patients will be assessed with Overall Benefit of Anesthesia Score (OBAS) questionnaires at postoperative days 1, 2 and 7. OBAS questionnaires will be done by personnel blinded to anesthesia technique. Patients will also be blinded as to which group they were in. Total morphine equivalents of intraoperative and postoperative pain medications will be calculated through postoperative day 7.
