Anestesia para lobectomia de lobo pulmonar caudal em cão por toracotomia intercostal – relato de caso

Abstract

Primary lung neoplasms are very rare in dogs. When they occur, they usually affect an entire lung lobe, and in these cases, total pulmonary lobectomy is the most indicated treatment, followed by chemotherapy as an adjuvant. In veterinary medicine, the mortality and morbidity rates associated with this type of surgery are still very high. Open chest surgeries are a challenge for the anesthesiologist, as they result in changes in respiratory and circulatory dynamics, and a challenge in mechanical ventilation, gas exchange and pulmonary perfusion, with emphasis on hypoxic pulmonary vasoconstriction. There are several studies that aim to study the best anesthetic method for this type of surgery, however, there is still no consensus. In this context, this monograph seeks to report the anesthesia for pulmonary lobectomy in the caudal lobe in a mixed breed dog, and the physiological changes caused by the surgical technique, as well as the postoperative management of the case, and a review on hypoxic pulmonary vasoconstriction, a condition common in this surgical approach to the chest.
