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

April 27, 2020 updated by: University of Tennessee

Comparison of Laparoscopically Assisted Transversus Abdominis Plane Block Using Liposomal Bupivacaine With Pre-incisional Bupivacaine for Post-operative Pain Control in Patients Undergoing Laparoscopic or Robotic Hysterectomy

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
