Introduction Transversus abdominis plane (TAP) block is a simple and effective technique of providing analgesia for lower abdominal surgeries with easily identifiable landmarks. This study investigated the postoperative analgesic efficacy of bilateral ultrasound-guided transversus abdominis plane blocks, in patients undergoing caesarean delivery at Paropakar Maternity and Women's Hospital, Kathmandu, Nepal. Methods Seventy-four patients undergoing caesarean section under spinal anesthesia were randomized to receive TAP block with bupivacaine (n =37) versus no TAP group (n =37), in addition to analgesia with intravenous paracetamol 1gram 6 hourly. At the end of the surgery, an ultrasound-guided TAP block was given bilaterally using 0.25% bupivacaine or no TAP block. Each patient was assessed postoperatively at regular intervals up to 24 hours for numerical pain rating scale and requirement of pethidine. SPSS version 20.0 software was used. Demographic data were analyzed using Student’s t-test and Mann–Whitney U-test. Results The TAP block with bupivacaine compared with no TAP group reduced the postoperative numerical pain rating scale. The time to first analgesic demand time was shorter in the control group (79.05±26.99) minutes compared to the bupivacaine group (416.75±87.29) minutes (P <0.05) which was statically significant. The 24 hours pethidine requirement was less in the bupivacaine group (P<0.05). There were no complications attributable to the TAP block. Conclusions Bilateral ultrasound-guided TAP block significantly reduced postoperative pethidine consumption in 24 hours after cesarean delivery.

Abstract Background Ultrasound-guided lateral transversus abdominis plane (TAP) block can provide definite analgesia to the anterior abdominal wall. However, whether this method is useful in renal surgery through the lateral abdominal wall pathway remains unknown. The study aimed to evaluate the analgesic efficacy of lateral TAP block for retroperitoneoscopic partial or radical nephrectomy. Method In this prospective, randomized, double-blind, placebo-controlled trial, eligible patients were randomized into two groups. After anaesthesia induction, ultrasound-guided lateral TAP block was performed with either 30 ml of 0.4% ropivacaine (Group T) or an equivalent volume of normal saline (Group C). The primary outcomes were opioid consumption during surgery and in the first 24 h after surgery. Secondary outcomes included postsurgical pain intensity immediately awakening from anaesthesia and at 0.5, 1, 2, 6, 12, and 24 h after surgery, as well as recovery variables including the incidence of postoperative nausea and vomiting (PONV), sleep quality, time to first ambulation, drainage and length of hospital stay. Results A total of 104 patients were enrolled and randomized (53 in Group T and 51 in Group C). Laparoscopic surgery was converted to open surgery in one patient of Group T; this patient was excluded from the outcome analysis. The opioid consumption during surgery (intravenous morphine equivalent dose: median 35.0 mg [interquartile range 18.0, 49.6] in Group C vs. 40.3 mg [20.9, 59.0] in Group T, P = 0.281) and in the first 24 h after surgery (10.8 mg [7.8, 21.7] in Group C vs. 13.2 mg [8.0, 26.6] in Group T, P = 0.311) did not differ significantly between groups. There were no significant differences between groups regarding the pain intensity at all time points after surgery and the recovery variables (all P > 0.05). Conclusions Our results showed that, in patients undergoing retroperitoneoscopic renal surgery, preoperative lateral TAP did not decrease intra- and postoperative opioid consumption, nor did it relieve pain intensity or promote postoperative recovery in the first 24 h after surgery. However, the trial might be underpowered. Trial registration This study was registered on November 4, 2017, in the Chinese Clinical Trail Registry with the identification number ChiCTR-INR-17013244.

Abstract Background Ultrasound-guided lateral transversus abdominis plane (TAP) block can provide definite analgesia to the anterior abdominal wall. However, whether this method is useful in renal surgery involving access through the lateral abdominal wall remains unknown. Therefore, the study aimed to evaluate the analgesic efficacy of lateral TAP block for retroperitoneoscopic partial or radical nephrectomy. Method In this prospective, randomized, double-blind, placebo-controlled trial, eligible patients were randomized into the intervention (T) or control (C) groups. After anaesthesia induction, ultrasound-guided lateral TAP block was performed preoperatively with 30 ml of 0.4% ropivacaine and an equivalent amount of normal saline in groups T and C, respectively. The primary outcomes were opioid consumption during surgery and in the first 24 h after surgery. Secondary outcomes were postsurgical pain intensity upon immediately awakening from anaesthesia and at 0.5, 1, 2, 6, 12, and 24 h after surgery as well as recovery quality variables including the incidence of postoperative nausea and vomiting (PONV), sleep quality, time to first ambulation, drainage and length of hospital stay. Results A total of 104 patients were enrolled and randomized: 53 and 51 in groups T and C, respectively. Laparoscopic surgery was converted to open surgery in one patient. Thus, he was excluded from the analysis. The median intraoperative and postoperative opioid consumption (oral morphine equivalent dose, o-MED) in the first 24 h after surgery were 105.0 and 32.5 mg in Group C, respectively, and the corresponding values in Group T were 121.0 and 39.7 mg, all of which were not significant (P = 0.284 and 0.311). Postsurgical pain intensity at all time points was comparable between the groups (all P > 0.05). Intergroup differences in the recovery quality variables were not significant (all P > 0.05). Conclusion Our findings demonstrated that preoperative lateral TAP could not decrease intraoperative or postoperative opioid consumption or pain intensity in the first 24 h after surgery, nor could it promote postoperative recovery in patients undergoing laparoscopic renal surgery through retroperitoneal access.

Background: This study aimed to determine whether ultrasound-guided transversus abdominis plane (TAP) block is more effective in reducing postoperative pain and analgesic consumption than local anesthetic infiltration (LAI) at the port site for elective laparoscopic gynecological surgeries.Methods: Eighty patients with the American Society of Anesthesiologists status I/II undergoing laparoscopic gynecology surgery were enrolled for this randomized control trial. After general anesthesia was administered, patients in group C received LAI at each port site, and patients in group T received bilateral ultrasound-guided TAP. Postoperative pain was assessed at time intervals of 1/2, 2, 4, 6, 8, and 24 h using the numeric pain scale (NPS). Clinical metrics such as postoperative analgesic diclofenac consumption, need for rescue fentanyl, nausea-vomiting scores, and antiemetic requirements were also recorded.Results: Seventy-four patients were included in the final analysis. Postoperatively, patients in group T had significantly lower NPS than those in group C (P < 0.05). The highest difference in the postoperative NPS was observed at 2 h (median [1Q, 3Q]; group C = 3 [2, 4]; group T = 1 [0, 2]; P < 0.001). A statistically significant difference was observed in the frequency of diclofenac (75 mg intravenous) requirement between the groups (P = 0.010). No significant difference was observed between the groups in need of rescue fentanyl or antiemetic and the nausea-vomiting scores.Conclusions: In patients undergoing laparoscopic gynecological surgery, ultrasound-guided TAP block provided greater postoperative analgesic benefits in terms of lower NPS and reduced analgesic requirements than port site LAI.
