When compared to general anesthesia (GA), MAC with regional anesthesia has been associated with reduced systemic adverse effects and shorter recovery times, although regional anesthesia carries additional costs and potential complications of its own. A new technique involving the infiltration of high-volume, low-concentration (VL) local anesthetic was therefore developed. When used in conjunction with MAC, we refer to this technique as MAC-VL.

All patients received a standardized injection of local anesthetic around the proposed operative sites before the procedure; anesthesia type was MAC (n = 48) or GA (n = 111). The primary outcome was time to discharge, defined as the interval from incision closed to hospital discharge.
