Abstract
Active warming of birds under general anesthesia is required to prevent hypothermia and its life-threatening consequences. The ability of a forced-air warming system to provide thermal homeostasis during isoflurane anesthesia of 10 Hispaniolan Amazon parrots (Amazona ventralis) was compared to a circulating-water blanket and an infrared heat emitter. Each bird was anesthetized once weekly for a 60-minute trial of each of 5 methods: no thermal support (control), surgical drape only, towel-covered circulating-water blanket and drape, infrared heat emitter and drape, and forced-air warmer and drape. An esophageal thermometer was used to measure the bird's core body temperature during each trial, and the temperature of the surgical area immediately adjacent to the bird as well as the ambient room temperature were also recorded. Time zero was 5 minutes after intubation. None of the warming methods prevented a significant decrease in core body temperature measured during the 60-minute trial period. A significant decrease in core body temperature was observed within 15 minutes with all warming methods except the forced-air warmer, which prevented a significant decrease in temperature before 30 minutes. Even though the forced-air warmer did not prevent a drop in core body temperature during the last 30 minutes of the trial, the temperature remained within the clinically acceptable range of 38.3–40.6°C. A significant increase occurred in the temperature of the surgical area immediately adjacent to each bird from 15 to 60 minutes for all warming methods, but the magnitude of the increase was not different among modalities. The forced-air warming system proved superior to traditional heating methods in restricting heat loss and is an effective modality for the prevention of hypothermia during isoflurane anesthesia of Hispaniolan Amazon parrots in clinical practice or a research setting.
