Veneziano G, et al. - Researchers assessed the efficacy of perineural dexamethasone as an adjunct to femoral nerve block in children (aged 10–18 years) presenting for arthroscopic knee surgery and randomized to 1 of 3 groups: ropivacaine 0.5% and intramuscular saline (group R), ropivacaine 0.5% plus perineural dexamethasone 0.1 mg/kg (maximum 4 mg) and intramuscular saline (group D), and ropivacaine 0.5% and intramuscular dexamethasone 0.1 mg/kg (maximum 4 mg) (group M). In this patient population, no improved analgesia was provided by perineural or intramuscular dexamethasone when administered as an adjuvant to femoral nerve block.
