Title: Effect of intravenous lidocaine on postoperative pain of microvascular decompression
Abstract: Objective To study the analgesic effect of intravenous lidocaine on postoperative pain of microvascular decompression.Methods Eighty patients scheduled for microvascular decompression were randomized into two groups,who either received placebo or lidocaine 1.5 mg/kg bolus before the induction of anesthesia followed by 2 mg/(kg·h)continuous IV.The patients underwent general anesthesia and postoperative pain was freated with patient-controlled IV fentanyl analgesia.The visual analog scale scores for pain and side effects were recorded at 2,4,6,12,and 24 hours after surgery.Results The visual analog scale scores for pain at 2,4,6,12,and 24 hours were lower in the lidocaine group than those in the placebo group(P0.05).The total dose of fentanyl(0-24 h after surgery) was lower in the lidocaine group than that in the placebo group(P0.05).The incidence of nausea and vomiting was smaller in the lidocaine group than that in the placebo group(P0.05).Conclusions Ⅳ lidocaine in microvascular decompression can reduce the fentanyl consumption and incidence of nausea and vomiting,which is a useful multimodal analgesic method.
