AI Article Synopsis
- A study evaluated the effectiveness of the transversus abdominis plane (TAP) block in reducing pain and opiate use in hernia surgeries, since it's known to help with abdominal surgeries.
- The analysis included 8 randomized clinical trials with 791 patients, showing that those who received the TAP block used significantly less morphine and reported lower pain scores at 24 hours post-surgery.
- Additionally, patients with TAP block experienced less postoperative nausea and vomiting, along with fewer general complications compared to those without the block.
Article Abstract
Background: Transversus abdominis plane (TAP) block reduces opiate requirements and pain scores in abdominal surgery, but the effect has not been evaluated in hernia surgery. The aim of this study was to evaluate the efficacy of TAP block in hernia surgery.
Methods: A meta-analysis of randomized clinical trials (RCTs) evaluating the effect of TAP block in adults undergoing hernia surgery was performed. The primary outcomes were morphine requirements 24 hours after surgery and the number of rescue analgesia patients. Secondary outcomes were pain scores on rest and on movement at 24 hours after surgery, postoperative nausea and vomiting and general postoperative complications.
Results: The search strategy yielded 231 articles after duplicates have been removed, and finally 8 RCTs with a total of 791 patients were included. In patients who received a TAP block, the cumulative morphine utilization was significantly reduced at 24 hours (weighted mean difference [WMD] -11.40 mg, -22.41 to -0.39; P=0.04). The number of patients needing a rescue analgesia (relative risk: 0.35, 0.22 to 0.55; P<0.001), the pain scores on rest 24 hours after surgery (WMD: -0.29, -0.55 to -0.04; P=0.02) and the pain scores on movement or coughing 24 hours after surgery (WMD: -0.70, -1.33 to -0.06; P=0.03) were all lower in patients who received a TAP block. There was also significant reduction in the postoperative nausea and vomiting, and the general postoperative complications in TAP block group.
Conclusions: Within a heterogeneous group of RCTs, TAP block reduces postoperative morphine requirements and the severity of pain after hernia surgery.

Effects of combined transversus abdominis plane block under direct vision and acupoint injection on promoting rapid recovery after laparoscopic cholecystectomy.

Objective: To study the effect of transversus abdominis plane (TAP) block under direct vision with acupoint injection on the rapid recovery of patients after laparoscopic cholecystectomy.
Methods: Ninety-three patients undergoing laparoscopic cholecystectomy at Hangzhou Hospital of Traditional Chinese Medicine from January 2023 to December 2023 were selected and divided into control, TAP block under direct vision (TAP-DV), and TAP-DV with acupoint injection (TAP-DVA) groups using a random number table method. Postoperative VAS, Ramsay score, IL-6, CRP, and postoperative rehabilitation indices were compared among the three groups.

Purpose: Transversus abdominis plane (TAP) block is a promising technique for postoperative pain control. In this study, we aimed to evaluate the efficacy of the TAP block in managing postoperative pain after laparoscopic totally extraperitoneal (TEP) inguinal hernia repair.
Methods: In this retrospective study, medical records of patients who had received ultrasonography-guided TAP blocks after surgery from January 2019 to August 2023 were reviewed and compared with those of patients who had not received.
Pain control and analgesic requirements following laparoscopy-assisted transversus abdominus plane (TAP) block compared to port site infiltration post-paediatric laparoscopic appendicectomy. A Randomised controlled trial.

Background: Appendicectomy is a common procedure in children. Regional anaesthesia helps reduce requirements for opioids and hospital stay and enhances recovery. Laparoscopic-assisted Transversus Abdominus Plane block (L-TAP) was shown to be efficient and potentially superior to port site infiltration (PSI); however, this was not previously studied in paediatric appendicitis.

Purpose: While surgeons agree that perioperative field blocks should be performed for open inguinal hernia surgery, there lacks consensus in the minimally invasive context. Prior small-scale randomized trials study pain scores only up to 24 h postoperatively. Thus, we sought to investigate the analgesic benefits of a bupivacaine transversus abdominis plane (TAP) block in the first 4 postoperative days.

Background: Opioid crisis is a national issue with significant economic burden and marked increase in opioid-related deaths, particularly following surgical procedures. Reducing opioid requirements while maintaining effective analgesia is critically challenging, perioperatively. Multimodal drug regimens and guided regional anesthesia (RA) have been adopted to address this issue.
