Résumé
Background: Femoral 3-in-1 block is one of the most effective methods in cases of hip nailing surgery because of its ease, low cost, and fewer complications. This study aims to evaluate the effect of adding dexamethasone to peripheral nerve block solution.Methods: Forty-four ASA (I,II & III) patients aged between 50-80 years, scheduled for elective hip-nailing surgery who met inclusion and exclusion criteria were enrolled in this double blind randomized controlled trial. Patients were allocated into two groups randomly; at the end of the surgery, femoral 3-in-1 nerve block was performed with 40 ml of bupivacaine 0.25% solution with or without 8 mg dexamethasone. Pain score was measured for 24 hours.Results: We found no significant difference in pain intensity scores until hour 0.5 and the scores were below 1. Thereafter, the VAS scores increased, yet it remained below 3 in the first 12 postoperative hours. Morphine was administered during hours 12-24 in both groups, when VAS scores reached to about 4. The total amount of morphine consumption was a little lower in the case group, although the difference was not statistically significant. Conclusion: Adding dexamethasone to bupivacaine 0.25% for 3-in-1 block has no more benefit than bupivacaine 0.25% alone for acute postoperative pain management after elective hip nailing surgery
