Changes in S100β (A) and NSE (B) plasma concentrations in patients receiving dexmedetomidine or saline intraoperatively (chemiluminescence immunoassay).
Data are expressed as the mean ± standard error of the mean and were analyzed by two-way analysis of variance. NS group (n = 52): Sevoflurane anesthesia with normal saline; DS group (n = 54): sevoflurane anesthesia with DEX. T0 (baseline): Before DEX infusion; T1: induction of anesthesia; T5: immediately after I-gel laryngeal mask airway removal. DEX: Dexmedetomidine; NSE: neuron-specific enolase.
