Abstract

Digital nerve block is one of the multimodal analgesia methods used in finger trauma cases. According to some studies, dexamethasone needs further investigation before being used routinely. We therefore investigated dexamethasone's effect on the parameters of digital nerve block. In this double-blind clinical study, 60 patients were allocated to two groups: lidocaine alone and lidocaine + dexamethasone. Groups were compared for pain intensity, analgesia duration and demographic characteristics. Patients in the intervention group received 3 cc 2% lidocaine + 1 cc (equivalent to 4 mg) dexamethasone and patients in the control group received 3 cc lidocaine 2% + 1 cc normal saline. The two groups were comparable for age and gender. In the lidocaine + dexamethasone group, postoperative pain severity was significantly lower and the pain-free period was longer (P < 0.05). Dexamethasone as an adjuvant in digital nerve block after trauma reduced the severity of postoperative pain and increased the pain-free period. © 2021 SFCM
