Discharge times for knee arthroscopy in spinal vs. general anesthesia

Background Spinal anesthesia (SPA) and general anesthesia (GA) are both safe techniques for knee arthroscopy. In this prospective, single-centre, randomised, clinical trial we compared the discharge times of SPA using 50mg hyperbaric prilocaine 2% and GA with propofol and sufentanil in patients undergoing ambulatory knee arthroscopy.
