Transversus abdominis plane block as a component of multimodal analgesia for laparoscopic cholecystectomy

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

“…In addition, postoperative VAS scores are positively correlated with total PCA consumption, and negatively correlated with total intraoperative consumption of remifentanil [27]. In addition,…”

“…Shin et al [28] also showed that the obli que subcostal TAP block decreased pain during rest and move ment at 4 hours after surgery significantly more than lateral TAP block, and significantly more at all times after surgery than no TAP block. intravenous PCA [27,29,30]. In a previous study, TAP blocks were found to have additional analgesic effects when used with intravenous tramadol-based PCA alone during the first 24 hours after surgery, and subcostal TAP block was associated with lower VAS scores than lateral TAP block in patients that underwent laparoscopic cholecystectomy [27].…”

“…intravenous PCA [27,29,30]. In a previous study, TAP blocks were found to have additional analgesic effects when used with intravenous tramadol-based PCA alone during the first 24 hours after surgery, and subcostal TAP block was associated with lower VAS scores than lateral TAP block in patients that underwent laparoscopic cholecystectomy [27]. However, Guardabassi et al [31] reported that a combination of TAP block and opioid-based PCA did not improve postoperative pain after laparoscopic hysterectomy.…”

“…A few papers compared lateral TAP block with posterior TAP block [25,26], and thus, differences between the efficacies of these blocks remain unclear, although it has been suggested posterior TAP block provides more effective postoperative pain control in patients after lapar oscopic gynecologic surgery [26]. However, oblique subco stal TAP block has been reported to decrease VAS scores sig ni ficantly more than lateral TAP block after laparoscopic chole cystectomy [27]. Shin et al [28] also showed that the obli que subcostal TAP block decreased pain during rest and move ment at 4 hours after surgery significantly more than lateral TAP block, and significantly more at all times after surgery than no TAP block.…”

Sensory Assessment and Regression Rate of Bilateral Oblique Subcostal Transversus Abdominis Plane Block in Volunteers

“…The area of cutaneous sensory block of the anterior abdomen regressed over the ensuing 22 hours in the following manner: 90%, 87%, 73%, 50%, 22%, 3%, and 0% at 0. 5,6,10,14,18,22, and 26 hours, respectively.…”
