Abstract: Objective To explore the effect of preoperative local blocking with compound lidocaine hydrochloride (CLH) on postoperative pain of patients undergoing craniotomy.Methods40 patients suffered from superatentorial occupying lesion and scheduled for craniotomy were randomly divided into the CLH group and control group with 20 cases in each group. In the CLH group, local blocking with CLH was performed just before craniotomy, while in control group local blocking with 0.5% procaine was performed preoperatively and all patients of two groups used patient-controlled intravenous analgesia (PCIA) with fentanyl postoperatively. Postoperative pain was assessed for 48 hours according to visual analogue scale (VAS), and the comparison of analgesia-related postoperative complications of the two groups was demonstrated.ResultsThere was no significant difference in VAS postoperatively and incidence rate of complications between two groups ( P>0.05).ConclusionCompound lidocaine hydrochloride local infiltration may provide a safe and effective analgesia for postoperative pain in patients after craniotomy.
