Abstract

The purpose of the study was to evaluate recovery from general anesthesia in a day-care surgery unit. A group of forty-three patients underwent surgery under general anesthesia with enflurane (N = 14), isoflurane (N = 10), or halothane (N = 19). Anesthesia lasted 20-95 min (average, 45.3 min). Heterophoria was measured with the Maddox Wing; results are expressed in prism diopters. Patients were measured before anesthesia (condition 1) 1.5, 2.5, and 3.5 h after the end of anesthesia (conditions 2, 3, and 4).
