Intraoperative Ultrasound-guided Transversus Abdominis Plane Block in Lower Abdominal Surgery

Abstract

Background: Ultrasound-guided transversus abdominis plane (TAP) block has been used for analgesia in lower abdominal surgery. In the literature, there are inconsistent reports regarding the efficacy of TAP block in different open abdominal procedures. Therefore, we conducted this prospective randomised doubleblind study to evaluate the pattern of perioperative analgesia and to validate the efficacy of TAP block in patients undergoing lower abdominal surgery.

The Analgesic Efficacy of Ultrasound-Guided Transversus Abdominis Plane Block in Adult Patients

“…43 Ultrasound-guided TAP block was performed before the surgery in 18 trials (58%). [2][3][4]7,42,43,[46][47][48]50,51,[53][54][55][56]58,59,61 The approach was subcostal in 2 trials (6%), 7,61 lateral in 18 trials (58%), 3,[42][43][44][45][47][48][49][50]52,58,59,[62][63][64][65][66]68 posterior in 8 trials (26%), 2,4,46,51,55,56,60,67 and was not specified in 3 trials (10%). 53,57,61 With the exception of 3 trials, 53,54,61 where it was not specified, the authors pe...…”

“…The trials were conducted on participants who underwent abdominal laparotomy (45%), 3,42-54 abdominal laparoscopy (32%), 2,4,7,55-61 and cesarean delivery (23%). [62][63][64][65][66][67][68] Attempts were made to contact 22 authors, 3,[42][43][44][45][46][47][48][49]51,[53][54][55]57,[60][61][62][63][64][65]67,68 and 11 authors provided the additional data requested. 3,45,48,53,54,57,61,[63][64][65]68 In 4 trials, data were approximated from median and range.…”

“…3,45,48,53,54,57,61,[63][64][65]68 In 4 trials, data were approximated from median and range. 43,44,55,56 Ultrasound-guided TAP block was combined with general anesthesia in 25 trials (80%), [2][3][4]7,[42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61]68 with spinal anesthesia and intrathecal long-acting opioid in 3 trials (10%), [64][65][66] or with spinal anesthesia and intrathecal short-acting opioid in 3 trials (10%). 62,63,67 The volume of local anesthetic used per side varied between 12 mL 47 and 30 mL 7 with a total dose of bupivacaine equivalent ranging from 60 mg 47 to 214 mg. 52 Three trials combined the local anesthetic with epinephrine, 7,48,57 whereas 1 trial adm...…”

Transversus abdominis plane block: The new horizon for postoperative analgesia following abdominal surgery

“…Khan et al studied USG guided TAP block in lower abdominal surgeries and found it efficient mode of analgesia in the intraoperative and immediate post operative period for patients undergoing lower abdominal surgeries (open appendectomy and inguinal hernia surgery) [40].…”
