Protocolo anestésico para orquiectomia em canino com Bav grau II : Relato de caso

Abstract

Atrioventricular block (AVB) in dogs is a condition that affects electrical communication between the atria and ventricles of the heart, and is classified into three degrees and also diagnosed by electrocardiogram. Thus, in this case report, a male canine, of approximately three years of age, was submitted to pre-anesthetic evaluation for an orchiectomy. During the physical examination, a discrepancy between the animal's heart rate and behavior was identified, leading to the suspicion of a second-degree atrioventricular block (AVB), later confirmed by electrocardiogram. After returning for atropine administration to adjust the anesthetic protocol, the orchiectomy was successfully performed, highlighting the importance of early diagnosis and appropriate treatment of cardiac conditions to ensure patient safety during surgical procedures. Thus, the situation illustrates the challenges and the importance, mainly, of a thorough cardiac evaluation, especially in animals that will be exposed to anesthesia, since dogs of any breed and age can be affected.
