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. Liposomal bupivacaine: 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.

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 0.25% bupivacaine injected on each side. Regular bupivacaine: 20mL of 0.25% bupivacaine injected on each side.

Transversus Abdominis Plane (TAP) Block With Liposomal Bupivacaine
n=30 Participants
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. Liposomal bupivacaine: 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.
