Background And ObjectivesThe major determinant of variable operating room costs is surgical time. A number of factors contribute to surgical time. This study was designed to determine whether regional anesthesia decreases surgical time when compared with general anesthesia over several surgical procedures.MethodsA search was conducted for clinical trials that reported surgical times and which compared outcomes from regional versus general anesthesia. A meta-analysis of these trials was completed to determine whether, on average, among many surgeons and surgical procedures, the use of regional anesthesia affects surgical time. Confidence intervals were calculated and random effects meta-analysis was used to pool results.ResultsTwenty-six studies (with 1,874 patients) were used in the meta-analysis. Regional anesthesia does not significantly decrease surgical time versus general anesthesia (mean general minus regional difference was 1.7 minutes, 95% confidence interval -0.5 to 3.9 minutes).ConclusionsOverall, the use of regional anesthesia does not significantly decrease surgical time.
