Background and Aims: Addition of dexamethasone to levobupivacaine in the peripheral nerve block provides improved pain scores, prolonged pain relief, and reduced postoperative opioid requirement. However, the evidence regarding its efficacy in the transversus abdominis plane (TAP) block is limited. Therefore, we conducted this study to evaluate the potential benefits of combining dexamethasone with levobupivacaine in the subcostal TAP block during the first 24 h after laparoscopic cholecystectomy. Materials and Methods: Seventy-six patients were enrolled in the study and divided into two groups to receive 20 ml of 0.25% levobupivacaine with 1 ml NS bilaterally (Group LS) or 20 ml of 0.25% levobupivacaine with 4 mg dexamethasone bilaterally (Group LD). Each patient received a standard multimodal analgesic regimen. Pain scores were recorded at rest and during coughing at 0, 2, 4, 6, 12, and 24 h postoperatively. Total opioid consumption and associated complications were recorded during the first 24 h. Results: Pain scores were lower in the LD group as compared to the LS group at all time points. Reduction in Numeric Rating Scale values was statistically significant at 4, 6, and 12 h both at rest and during coughing. Estimated P values on coughing at these time points were 0.000, 0.001, and 0.017, respectively. Postoperative opioid requirement was also significantly reduced between 2 and 24 h (P = 0.007). We did not record any complications in our study population. Conclusion: The combination of dexamethasone and levobupivacaine in the subcostal TAP block significantly improves the efficacy of multimodal analgesic regimen during the first 24 h after laparoscopic cholecystectomy.
