Abstract
Abstract The cardiopulmonary and anesthetic effects of isoflurane and propofol were determined in 10 healthy, adult Hispaniolan Amazon parrots (Amazona ventralis). Anesthesia was induced and maintained with isoflurane in oxygen for 30 minutes. Cardiopulmonary parameters including heart rate, respiratory rate, relative arterial oxygen hemoglobin saturation (SpO2), and esophageal temperature were recorded at 1, 2, 3, 4, 5, 10, 15, 20, 25, and 30 minutes. End-tidal CO2 (EtCO2) concentrations and inspired and expired end-tidal isoflurane concentrations were recorded continuously. Before the study continued, birds were allowed to recover from isoflurane anesthesia for at least 2 hours. In a second trial, anesthesia was induced by intravenous administration of propofol (5 mg/kg) and maintained for 30 minutes by constant rate infusion of propofol (1 mg/kg per min IV). No supplemental oxygen was provided. Cardiopulmonary parameters and EtCO2 concentrations were recorded as in the isoflurane trial. Induction times...
