Comparing Local Anesthetics for TAP Block During Abdominally-based Free Flap for Breast Reconstruction

24. desember 2021 oppdatert av: Galen Perdikis, Vanderbilt University Medical Center

Double-Blinded Randomized Control Trial Comparing Liposomal Bupivacaine and Bupivacaine Hydrochloride in Transversus Abdominis Plane Blocks Prior To DIEP Flap for Breast Reconstruction

This study will compare the efficiency of transversus abominus plane (TAP) block using liposomal bupivacaine versus plain bupivacaine that is administered in the operating room under ultrasound guidance prior to the in patients undergoing abdominally-based free flap breast reconstruction at Vanderbilt University Medical Center.

Studieoversikt

Detaljert beskrivelse

Transversus Abdominis Plane (TAP) blocks are commonly used as part of Enhanced Recovery After Surgery (ERAS) pathway. This prospective, double-blinded, randomized control trial compares post-operative pain and narcotic consumption after deep inferior epigastric artery perforator (DIEP) breast reconstruction with liposomal bupivacaine (LB) compared to bupivacaine hydrochloride (BHCl). Subjects undergoing DIEP flaps were randomly assigned LB or BHCl, performed using ultrasound-guided TAP block technique pre-procedurally. Primary outcomes were postoperative narcotic analgesia required in oral morphine equivalents (OME) from postoperative day (POD) 0 to 7. Secondary outcomes included POD 1-7 pain Numeric Rating Scale (NRS), non-narcotic pain medication consumption, time to first narcotic use, return of bowel function, and length of stay (LOS).

Intervensjon / Behandling
Eksperimentell: TAP block with liposomal bupivacaine
Local analgesia (TAP blocks) will be administered under ultrasound guidance in the operating room after the patient is intubated and under general anesthesia. Under sterile conditions and ultrasound guidance, the fascial plane between the internal oblique and transversus abdominis muscles (muscles of the abdominal wall) will be identified at the anterior axillary line, midway between the costal margin and iliac crest. The epidural needle will be inserted through the skin to the appropriate fascial plane, and the local anesthetic will be injected in that plane. 20mL of Exparel® 1.3% mixed with 20mL of 0.25% bupivacaine, for a total of 40mL of local anesthestic mixture, 20mL to be injected on each side.
