RESUMO
OBJECTIVES: 1. To introduce use of the postanesthesia recovery score (assessing consciousness, mobility, ventilation, hemodynamics and blood analysis) as a good method for evaluating and classifying recovery from anesthesia in the postoperative care unit. 2. To determine overall patient progress and assess the influence of various patient, anesthetic and surgical factors. PATIENTS AND METHODS: This was a multicenter study of 1,227 patients. We excluded all patients who were to be transferred to intensive care units after surgery. A score of 10 or more, with no single item score equal to 0, was considered optimal for discharge from the postanesthesia care unit. RESULTS: The lowest score upon admission to the unit was among patients who had undergone high abdominal surgery (16.4%). Scores over 9 belonged to patients who had undergone lower abdominal and perineal surgery (87.5 and 95.3%, respectively). Scores were < or = 9 in patients who received inhaled anesthetics (42%). Intravenous anesthesia patients (84.4%) had scores over 9. The local-regional anesthetic procedures with the best scores were axilar blocks and local infiltrations. Patients staying longer in the recovery unit were those classified as ASA III, those whose procedures lasted longer than 120 minutes, those undergoing surgery on the upper abdomen or on extremities, those receiving isoflurane and pancuronium, and those suffering adverse events during and after the procedure. Factors influencing perioperative events were age, duration of procedure and history of intraoperative events.
