Comparison of posterior and subcostal approaches to ultrasound-guided transverse abdominis plane block for postoperative analgesia in laparoscopic cholecystectomy

Dermatomal spread following posterior transversus abdominis plane block in pediatric patients: our initial experience

“…The transversus abdominis plane (TAP) block was first described as an anatomic landmark-based technique in adults (1,2). Since then, several ultrasound-guided approaches to the TAP have been described in both adults and children for lower and upper abdominal surgeries, but reports on efficacy and cutaneous sensory changes remain inconsistent and conflicting (3)(4)(5)(6)(7)(8)(9)(10). In adults, the ultrasound-guided midaxillary TAP (3) has been shown to provide unreliable dermatomal sensory coverage (4), while landmark-based techniques and posterior TAP blocks have been shown to provide coverage up to a T6 dermatomal level (11)(12)(13)(14).…”

“…An oblique subcostal approach in the use of a single-injection TAP block was effective in the control of LC postoperative pain and decreased opioid consumption 33 . This block showed lower postoperative pain and opioid need scores in comparison to the posterior TAP block or no blockade 35 . When two groups undergoing epidural block were compared in a LC surgery, the associated use of clonidine with levobupivacaine resulted in less analgesic need in the treatment of shoulder pain compared with clonidine with ropivacaine, but both groups had a high decline in blood pressure, requiring vasopressors 34 .…”

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

“…Bhatia et al [23] reported subcostal TAP block was better than posterior TAP block for providing postoperative analgesia on incisions mainly involving the supra-umbilical region during laparoscopic cholecystectomy. In addition, they found the subcostal TAP group had significantly lower pain scores at 4 hours postoperatively and opioid consumptions at 24 hours postoperatively.…”
