Anesthetic classification of the physical status and surgical-anesthetic mortality in dogs

<p></p><p>ABSTRACT The classification ASA (American Society of Anesthesiologists) is an important tool for assessing a patient's pre anesthetic. Thus, it is used in many studies because it has close relation with anesthetic morbidity and mortality. This classification was performed on 243 canine patients undergoing surgical procedures at the Veterinary Teaching Hospital. The results obtained were as follows: ASA I (38, 15.64%), ASA II (53; 21.81%), ASA II Emergency (E) (2; 0.82%), ASA III (78; 32.10%), ASA III E (23; 9.46%), ASA IV (11; 4.53 %), ASA IV E (36; 14.81%), and ASA V (2; 0.82%). Most patients were ASA III (moderate systemic disease), demonstrating that in the analyzed service the most operated animals are carriers of disease. The mortality rate was 2.46%, with most deaths occurring postoperatively and in patients with an emergency. The greatest risks are related to patients with more severe categories of the classification ASA, in emergency surgery, and especially in the postoperative period.</p><p>
