Regional anesthesia and ambulatory surgery

Advances in surgery and anesthesia have allowed for more surgeries to be done on an outpatient basis. A recent important advance entails availability of suitable recovery criteria to capitalize on the benefits of regional anesthesia for ambulatory surgery. With ever-escalating healthcare costs and expectations for faster recovery, anesthesiologists are now challenged to design anesthesia plans focused on Phase I postanesthesia care unit bypass and early facility discharge. Satisfying the recently published WAKE Score criteria upon operating room exit is associated with hospital cost reductions. This review highlights regional anesthesia techniques with focus on outpatient orthopedics. We also discuss 'multimodalities' addressing postoperative nausea and vomiting prophylaxis, perioperative analgesia (including perineural analgesia), and sedation-hypnosis, which are all central to timely recovery using now-available suitable recovery criteria.

Ultrasound-guided regional anesthesia has increased the comfort level for many anesthesiologists performing blocks. Other advances include better monitoring of anesthetic depth for titration of sedatives, en route to avoiding emetogenic and hyperalgesic volatile anesthetics.

Routine regional anesthesia use, multimodal postoperative nausea and vomiting prophylaxis, multimodal sedation-hypnosis, and multimodal analgesia, along with avoiding volatile agents and short-duration opioids, can lead to both routine Phase 1 postanesthesia care unit bypass and expedited same-day discharge, when using suitable recovery criteria.
