ABSTRACT

Several methods are performed to control the pain after a laparoscopic cholecystectomy. Recently, the transverse abdominis plane block has been proposed to compensate for the problems developed by preexisting methods. This study was designed to evaluate the effect of the ultrasound-guided transverse abdominis plane block (US-TAP block) and compare efficacy according to the concentration of local analgesics in patients undergoing laparoscopic cholecystectomy.
Fifty-four patients undergoing laparoscopic cholecystectomy were randomized into three groups. The patients in Group Control did not receive the US-TAP block. The patients in Group B(0.25) and Group B(0.5) received the US-TAP block with 0.25% and 0.5% levobupivacaine 30 ml respectively. After the general anesthesia, a bilateral US-TAP block was performed using an in-plane technique with 15 ml levobupivacaine on each side. Intraoperative use of remifentanil and postoperative demand of rescue analgesics in PACU were recorded. The postoperative verbal numerical rating scale (VNRS) was evaluated at 20, 30, and 60 min, and 6, 12, and 24 hr. Postoperative complications, including pneumoperitoneum, bleeding, infection, and sleep disturbance, were also checked.
The intraoperative use of remifentanil, postoperative VNRS and the postoperative demand of rescue analgesics were lower in the groups receiving the US-TAP block (Group B(0.25) and Group B(0.5)) than Group Control. There were no statistically or clinically significant differences between Group B(0.25) and Group B(0.5). No complications related to the US-TAP block were observed.
The US-TAP block with 0.25% or 0.5% levobupivacaine 30 ml (15 ml on each side) significantly reduced postoperative pain in patients undergoing laparoscopic cholecystectomy.

    ABSTRACT: Background: Previous meta-analyses of the transversus abdominis plane (TAP) block have examined a maximum of 12 articles, including fewer than 650 participants, and have not examined the effect of ultrasound-guided techniques specifically. Recently, many trials that use ultrasound approaches to TAP block have been published, which report conflicting analgesic results. This meta-analysis aims to evaluate the analgesic efficacy of ultrasound-guided TAP blocks exclusively for all types of abdominal surgeries in adult patients. Methods: This meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. The primary outcome was cumulative IV morphine consumption at 6 hours postoperatively, analyzed according to the type of surgery, the type of surgical anesthesia, the timing of injection, the block approach adopted, and the presence of postoperative multimodal analgesia. Secondary outcomes included IV morphine consumption at 24 hours postoperatively; pain scores at rest and on movement at 6 and 24 hours postoperatively; and postoperative nausea and vomiting, pruritus, and rates of complications. Results: Thirty-one controlled trials including 1611 adult participants were identified. Independent of the type of surgery (abdominal laparotomy, abdominal laparoscopy, and cesarean delivery) but not independent of the type of surgical anesthesia (general anesthesia, spinal anesthesia with or without intrathecal long-acting opioid), ultrasound-guided TAP block reduced IV morphine consumption at 6 hours postoperatively by a mean difference of 6 mg (95% confidence interval [CI], -7 to -4 mg; I = 94%; P < 0.00001). The magnitude of the reduction in morphine consumption at 6 hours postoperatively was not influenced by the timing of injection (I = 0%; P = 0.72), the block approach adopted (I = 0%; P = 0.72), or the presence of postoperative multimodal analgesia (I = 73%; P = 0.05). This difference persisted at 24 hours postoperatively (mean difference, -11 mg; 95% CI, -14 to -8 mg; I = 99%; P < 0.00001). Pain scores at rest and on movement were reduced at 6 hours postoperatively (mean difference at rest, -10; 95% CI, -15 to -5; I = 92%; P = 0.0002; mean difference on movement, -9; 95% CI, -14 to -5; I = 58%; P < 0.00001). There were neither differences in the incidence of postoperative nausea and vomiting (I = 1%; P = 0.59) nor in the pruritus (I = 12%; P = 0.58) Two minor complications (1 bruise and 1 anaphylactoid reaction) were reported in 1028 patients. Conclusions: Ultrasound-guided TAP block provides marginal postoperative analgesic efficacy after abdominal laparotomy or laparoscopy and cesarean delivery. However, it does not provide additional analgesic effect in patients who also received spinal anesthesia containing a long-acting opioid. The minimal analgesic efficacy is independent of the timing of injection, the approach adopted, or the presence of postoperative multimodal analgesia. Because of heterogeneity of the results, these findings should be interpreted with caution.

    • "TAP block, first described in 2001 [4] is an effective adjunct to post-operative analgesia especially following lower abdominal incisions [5]. The technique has been used previously to provide analgesia following DCLC with mixed results [6] [7] [8] [9]. Reduced pain could potentially translate into low opiate requirements and hence reduced sedation and opiate induced nausea and vomiting. "

Similar findings were reported in a study by Ra et al.[15] in patients undergoing laparoscopic cholecystectomy where intraoperative remifentanil use was significantly lower in patients receiving either 0.5% or 0.25% bupivacaine in comparison to placebo.

    ABSTRACT: Background and Aims: Transversus abdominis plane (TAP) block has been shown to provide postoperative pain relief following various abdominal and inguinal surgeries, but few studies have evaluated its analgesic efficacy for intraoperative analgesia. We evaluated the efficacy of TAP block in providing effective perioperative analgesia in total abdominal hysterectomy in a randomized double-blind controlled clinical trial. Materials and Methods: A total of 90 adult female patients American Society of Anesthesiologists physical status I or II were randomized to Group B (n = 45) receiving TAP block with 0.25% bupivacaine and Group N (n = 45) with normal saline followed by general anesthesia. Hemodynamic responses to surgical incision and intraoperative fentanyl consumption were noted. Visual analog scale (VAS) scores were assessed on the emergence, at 1, 2, 3, 4, 5, 6 and 24 h. Time to first rescue analgesic (when VAS ≥4 cm or on demand), duration of postoperative analgesia, incidence of postoperative nausea-vomiting were also noted. Results: Pulse rate (95.9 ± 11.2 bpm vs. 102.9 ± 8.8 bpm, P = 0.001) systolic and diastolic BP were significantly higher in Group N. Median intraoperative fentanyl requirement was significantly higher in Group N (81 mcg vs. 114 mcg, P = 0.000). VAS scores on emergence at rest (median VAS 3 mm vs 27 mm), with activity (median 8 mm vs. 35 mm) were significantly lower in Group B. Median duration of analgesia was significantly higher in Group B (290 min vs. 16 min, P = 0.000). No complication or opioid related side effect attributed to TAP block were noted in any patient. Conclusion: Preincisional TAP block decreases intraoperative fentanyl requirements, prevents hemodynamic responses to surgical stimuli and provides effective postoperative analgesia.
