ObjectiveTo evaluate induced hypothermia and rewarming times in Hispaniolan Amazon parrots (HAP) anesthetized using isoflurane, sevoflurane, or desflurane, and to describe selected cardiovascular and respiratory effects. Study designRandomized, balanced, crossover experimental study AnimalsTwelve adult HAP (Amazona ventralis) MethodsParrots were premedicated with intramuscular butorphanol (0.5 mg kg–1) and anesthetized with the three inhalants with a 7 day washout period between events. Anesthesia was induced using isoflurane at 4 vol%, sevoflurane at 6 vol% or desflurane 12 vol% carried in oxygen, delivered via face mask. Following orotracheal intubation, anesthesia maintenance was with end-tidal concentrations of 1.4–2% (FE´Iso), 2.4–3% (FE´Sevo) and 8.5–9.2% (FE´Des). Hypothermia was defined as an esophageal temperature (BT) below 37.8 ºC. External heat support was provided when BT dropped to 37.5 ºC. Time for temperature decrease from 38.9 ºC to 37.5 ºC (T1), time to first increase in BT above 37.5 ºC (T2), and time from external heat support to achieving 38.9 ºC (T3) were recorded and compared via Friedman tests with post hoc Dunn’s test. Heart rate, respiratory rate, end-tidal carbon dioxide, amongst other variables, were evaluated. ResultsAll inhalants caused hypothermia (T1): isoflurane; 12 (2–37) minutes [median (range)], sevoflurane; 12 (4–18) minutes, desflurane; 11.5 (6–24) minutes, with no significant differences between treatments (p > 0.05). T2 was significantly (p = 0.042) longer for sevoflurane compared to desflurane, but not isoflurane. Transient apnea was observed with all inhalants, including 25% of birds anesthetized with sevoflurane. Second-degree atrioventricular block and ventricular escape beats occurred with all inhalants with hypothermia potentially exacerbating cardiac arrhythmias. Conclusion and clinical relevanceHypothermia rapidly developed in butorphanol-sedated Hispaniolan Amazon parrots anesthetized using isoflurane, sevoflurane or desflurane. Sevoflurane prolonged warming time. Hypothermia may be associated with an increased likelihood of bradyarrhythmia in parrots anesthetized with inhalants.
