Evaluation of a protocol for the prevention of hypothermia during general anesthesia in domestic dogs undergoing dental prophylaxis

Abstract

Justification.- Incorrect thermal management of the canine patient undergoing general anesthesia can generate recovery complications and even present the risk of death. Objective - to evaluate a normothermic protocol in healthy canine patients sometimes general anesthesia. Materials and methods.- 10 patients were recruited for a controlled clinical trial crossed type for intention to treat, the patients underwent two anesthetic procedures, the first without any means of maintenance of normothermia, and the second procedure accompanied by a protocol consisting of preheating for 30 minutes at 28 ° C, Survival Blanket ® reflective blanket + radiant light (250W infrared focus) to minimize the loss of temperature of the patients. Results - Rectal temperatures (peripheral temperature) were evaluated throughout the perioperative period (60 minutes), obtaining in the 10 patients in both cases, these data being analyzed by means of a statistical test (T-Test) found significant differences between applying and not applying said protocol. The statistically significant differences that were found were: at the end of the premedication (p value = 0.039), at the beginning of the induction (p value = 0.041), and throughout the maintenance (p value = 0.008 – 0.013 – 0.012 – 0.005 – 0.008 – 0.005 – 0.005). Conclusions - It was observed and demonstrated that combining active and passive methods help to minimize the loss of temperature of the patient
