Background And Aim:
Postoperative pain is an inevitable acute pain for which a multimodal analgesic approach is required. The aim of this study was to quantify and compare the efficacy of transverse abdominis plane (TAP) block as a postoperative analgesic for patients undergoing laparoscopic hysterectomies versus intravenous opioid analgesics.
Method:
Sixty female patients were enrolled and randomized into two groups following a computer-generated sequence of numbers. In group T (n=30) patients received an ultrasound-guided bilateral TAP block with 20 of 0.375% levobupivacaine on each side immediately after surgery. Patients in group O (opioid group, n = 30) received intravenous (i.v.) tramadol (100mg) immediately after surgery. Rescue analgesic (inj. tramadol 50mg) i.v. bolus given in both groups if visual analog scale (VAS) >4. In the postanesthesia care unit (PACU), the vital signs, episodes of nausea, vomiting, and VAS score of each patient were recorded every two hours for the first 24 hours.
Result:
Total consumption of rescue analgesic (inj. tramadol 50 mg i.v.) during the first 24 hours was significantly higher in group O (186.47+37.48mg) than in group T (107.28+26.34mg). No significant difference was observed in intraoperative vital parameters (HR, NIBP, SPO2). The VAS scores were significantly low in group T. Incidence of postoperative nausea and vomiting (PONV) was significantly higher in group O (13 out of 28 patients) than in group T (five out of 28 patients) with P value =0.043.
Conclusion:
Our study indicated bilateral ultrasound-guided TAP block is a good alternative to opioids for postoperative analgesia.
