Beneficial impact of epidural anesthesia on recovery after outpatient arthroscopy.

The ideal outpatient anesthetic provides analgesia, is readily reversible, has minimal complications, and allows for a prompt hospital discharge. Iatrogenic side effects, such as nausea/vomiting and pain, however, may hamper patient recovery and delay discharge. The influence of anesthesia [general (G) versus epidural (E)] was assessed in 260 patients (G = 181, E = 79) undergoing ambulatory knee arthroscopic surgery. Patients were studied before discharge and on follow-up (24 h) to evaluate the effect of the anesthetic technique. Discharge times were shorter in the E group (159 +/- 6 min SEM E, compared with 208 +/- 8 min SEM G), as was the incidence of pain (24.1% versus 49.7%), and nausea/vomiting (8.9% versus 32%) before discharge. Patient satisfaction was equal in the two groups. Our study shows that in select patients, epidural anesthesia is a viable alternative to general anesthesia for knee arthroscopy, offering the advantages of fewer side effects and earlier discharge times.
