Abstract

Purpose: We compared the recovery profiles, postoperative complications, perioperative OR utilization times, and times to discharge of patients undergoing ambulatory knee arthroscopy under spinal anesthesia (SA) or general anesthesia (GA). Methods: In this randomized, prospective study, 84 ASA I-II patients were randomized to receive either SA with 50 mg of 1% lidocaine, or a standardized GA. Postoperative pain, nausea and vomiting, sedation, OR utilization, postanesthesia care unit (PACU), and ambulatory surgical unit (ASU) recovery were compared. Results: Patients in the GA group had more pain in the PACU than the SA group (61% vs 15%, P <0.01), and a higher incidence of PACU analgesic use (59% vs 7.5%, P <0.01). Patients in the SA group were able to drink and eat sooner than the GA group (83 ± 23 vs 95 ± 22 min, P <0.05 and 88 ± 27 vs 105 ± 29 min, P <0.01, respectively). The times to sit, walk, and void were similar. The length of PACU and ASU stay between the GA and SA groups were similar (67 ± 17 vs 60 ± 19 min, P >0.05 and 122 ± 27 vs 127.9 ± 31 min, P >0.05, respectively). The incidence of backache was higher in the SA group (35 vs 13.6%, P <0.05) than the GA group. However, the incidence of sore throat was higher in the GA compared to the SA group (25% vs 2.5%, P <0.01). Conclusions: SA with 50 mg of 1% lidocaine provides an improved recovery profile for ambulatory knee arthroscopy. Discharge times were similar, and with the exception of backache and sore throat, the incidence of complications was similar.
