Description
Summary:Background and Aims: Many patients experience moderate-to-severe pain after laparoscopic cholecystectomy. We aimed to compare the efficacy of ultrasound-guided bilateral subcostal transversus abdominis plane (TAP) block with port-site infiltration for post-operative analgesia after laparoscopic cholecystectomy. Methods: Patients undergoing elective laparoscopic cholecystectomy under general anaesthesia were divided into two groups of 40 each to receive ultrasound-guided bilateral subcostal TAP block (T) with 0.25% bupivacaine 20 ml each side or port-site infiltration with 0.5% bupivacaine 5 ml each at 4 ports (I) at the end of the surgery before extubation. All patients received paracetamol 1 g intravenous 8th hourly. Tramadol 1 mg/kg intravenous bolus and diclofenac 1 mg/kg intravenous infusion were used as the first- and second-line rescue analgesics when Numerical Rating Scale (NRS) ≥4, or when the patient complained of pain. NRS at 1, 2, 3, 6, 12 and 24 h after surgery, time to first analgesic request and total dose of analgesics in 24 h were recorded. Chi-square test and independent t-test were used to compare qualitative and quantitative data, respectively. Results: Time to first analgesic (mean±SD) in Group I and Group T was 292.7 ± 67.03 and 510.3 ± 154.55 min and mean tramadol required was141.8 ± 60.01 mg and 48.69 ± 36.14 mg, respectively (P = 0.001 for both). Mean NRS at 2, 3, 6, 12 and 24 h was significantly lower in Group T. Conclusion: Ultrasound-guided bilateral subcostal TAP block provides superior post-operative analgesia after laparoscopic cholecystectomy compared to port-site infiltration.
