Randomized Controlled Trial
Perineural and Systemic Dexamethasone and Ulnar Nerve Block Duration A Randomized, Blinded, Placebo-controlled Trial in Healthy Volunteers.
The authors hypothesized that both perineural and systemic dexamethasone as adjuncts to bupivacaine increase the duration of an ulnar nerve block compared with bupivacaine alone, and that systemic dexamethasone is noninferior to perineural dexamethasone. ⋯ Perineural dexamethasone as an adjunct to bupivacaine in healthy volunteers resulted in a greater duration of an ulnar nerve block when compared with placebo. Systemic dexamethasone resulted in a similar duration as placebo.
