Risco anestésico de cães e gatos anestesiados em um hospital-escola: estudo retrospectivo de 267 casos

Abstract

Veterinary medicine has undergone great advances over time, causing the life expectancy of dogs and cats to increase considerably, also resulting in a greater probability of these animals, at some point in their lives, to be submitted to surgical and anesthetic procedures that , however simple they may be, always offer a certain degree of risk. The performance of an appropriate preoperative evaluation allows better knowledge of the animal and the determination of anesthetic risk through the ASA classification, created by the American Association of Anesthesiologists to categorize patients according to their physical condition. Based on this classification and the aid of complementary exams that are routine in veterinary practice, the anesthesiologist can perform a better stabilization of the patient and employ more appropriate drugs. This work brings a retrospective study of anesthetic procedures performed on dogs and cats attended at a teaching hospital from July to December 2019, classifying them according to ASA risk. Of the total of 267 procedures, 12 were classified as ASA I (4.5%), 190 as ASA II (71.2%), 52 as ASA III (19.4%), 12 as ASA IV (4.5%) and only 1 as ASA V (0.4%). It is concluded that most animals that perform anesthetic / surgical procedures in the teaching hospital in question have low to intermediate anesthetic risk.
