Transversus Abdominis Plane (TAP) Block Using Liposomal Bupivacaine in Metabolic and Bariatric Surgery Patients (TAP)

November 28, 2023 updated by: Wake Forest University Health Sciences

Single Blinded Randomized Trial of Transversus Abdominis Plane Block Using Liposomal Bupivacaine in Metabolic and Bariatric Surgery Patients

To investigate if laparoscopic Transversus Abdominis Plane (TAP) block using plain bupivacaine is equivalent to using liposomal bupivacaine in patients undergoing metabolic and bariatric surgery. The study will see if the plain bupivacaine group will be equivalent in terms of length of stay, Morphine Milligram Equivalents, Pain scores and patient satisfaction, but cost less.

Study Overview

Detailed Description

Compared to only Bupivacaine administered via TAP block, the study will investigate the analgesia effects to patients undergoing metabolic and bariatric surgery receiving TAP block with a Liposomal Bupivacaine mixture. To determine if patients undergoing metabolic and bariatric surgery receiving TAP block with a Liposomal Bupivacaine results in pain scores, as measured by visual analogic scale (VAS), that are equivalent compared to patients receiving TAP block with Bupivacaine only. Compared to TAP block with Bupivacaine only, the study will compare opioid consumption, and other effect differences to patients undergoing metabolic and bariatric surgery receiving TAP block with Liposomal Bupivacaine. The study will explore other effects, including pain score at 48 hours, and 72 hours after surgery, total opioid consumption required post op during their one-week post op visit as measured in morphine equivalences.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
24 Hour Visual Analogue Scale (VAS) Pain Score
Time Frame: Hour 24
Pain score at 24 hours post-operative, using visual analogue scale (VAS), ranging from 1 to 10. One indicates no pain, and 10 indicates the worst pain one could imagine.
Hour 24

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual Analogue Scale (VAS) Pain Scores
Time Frame: Hours,12, 48, and 72
Pain score at 12 hours, 48 hours, and 72 hours post-operative, using visual analogue scale (VAS), ranging from 1 to 10. One indicates no pain, and 10 indicates the worst pain one could imagine
Hours,12, 48, and 72
Morphine Equivalences - Immediate
Time Frame: Hour 24
Morphine milligram equivalences consumed during hospital stay
Hour 24
Morphine Equivalences - Week 1
Time Frame: Week 1
Morphine milligram equivalences prescribed and consumed as measured at one week follow up clinic visit
Week 1
Post-operative nausea and vomiting (PONV)
Time Frame: Week 1
Post-operative nausea and vomiting (PONV) measured by a numerical score (1: no nausea or vomiting, 2: some nausea no vomiting, 3: nausea and vomiting)
Week 1
Length of Hospital Stay
Time Frame: Day 3
Hospital length of stay in hours
Day 3
Patient Satisfaction Scores
Time Frame: Day 30
Patient Satisfaction score based on daily postop online surveys - These parameters will be scored via SeamlessMD on a phone application, as well as paper and pen on a standardized reporting form for patients less comfortable using technology - scored on a scale of 0-10, with 0 being "worst surgeon possible and 10 being "best surgeon possible."
Day 30
