Ultrasound-guided transversus abdominis plane block: description of a new technique and comparison with conventional systemic analgesia during laparoscopic cholecystectomy

Abstract

Ultrasonographic guidance enables exact placement of the local anaesthetic for TAP blocks. In patients undergoing laparoscopic cholecystectomy under standard general anaesthetic, ultrasound-guided TAP block substantially reduced the perioperative opioid consumption.

Observational Study to Evaluate Transversus Abdominis Plane (TAP) Block in Abdominal Surgery by Total Requirement of Diclofenac as a Post Operative Analgesia drug

“…The cumulative diclofenac consumption at 2, 4, 12, 18, 24 hours was also significantly less in study group compared to the control group. Our study results are comparable with Dawlatly et al [7] who showed 55% decrease in opioid requirement after USG guided TAP block in laparoscopic cholecystectomy. Niraj et al [8] showed 45% decrease in opioid requirement with USG guided TAP block in open appendicectomy.…”

“…POP technique described by Rafi, is associated with difficulties like anatomic variation of triangle of petit, difficulty in palpation of triangle in obese patients and complications like colonic puncture, liver injury [5], nerve injury or unpredictable spread of local anesthetic [7].…”

“…Recent studies by Hebbard et al [14,15] (posterior TAP block), T. M. Tran (cadaveric study), Dawlathy (Lap cholecystectomy) [7], Niraj et al (open appendicectomy) [8] , Belary et al (caesarean section delivery) [9] , D.J Sandeman (Lap appendicectomy) [11] have all proved that "In plane" USG guidance ensures the exact position of LA between the IOAM and TAM, resulting in improve safety and efficacy.…”

Comparison of analgesic efficacy of oblique subcostal and lateral transversus abdominis plane block after laparoscopic cholecystectomy

“…TAP blocks have been reported to reduce postoperative VAS, morphine consumption, and systemic analgesic requirements, and to reduce opioid-related side effects after abdominal surgeries, including laparoscopic surgery, as compared with placebo blocks [2,[14][15][16][17][18]. Previous reports have shown TAP blocks provide significant pain relief from within 2 hours of laparoscopic surgery, but not at 24 hours postoperatively [15,18].…”

Trans Abdominis Plan Block Reduce Postoperative Analgesic Requirement and Prolong Time to First Analgesic Request in Abdominal Surgery at University of Gondar Hospital: Prospective Observational Study

“…This discrepancy could be the result of poor pain management protocol, difference in intraoperative analgesic protocols and different types of surgery. Unlike the referenced study areas, patients in the current study were managed with small dose (commonly 25-50 mg) of tramadol after repetitive attempts made to kill pain with Non Steroidal Anti Inflammatory Drugs, though it is known that NSAIDs are not sufficient as the sole analgesic agent after major surgery [25,26]. Time for the first rescue tramadol request was significantly prolonged in favor of the TAP group (360 min vs 156 min).…”
