Multimodal anesthesia for pulmonary lobectomy as treatment of spontaneous pneumothorax in a dog
Keywords:
Dog, surgery, pulmonary bleb, anesthetic protocol, lungAbstract
Lung bullae are air-filled cavitary lesions that occur in the lung parenchyma and surgical resection of the lung lobe is indicated. Essentially, the anesthesia of these patients requires ventilatory support, an individualized anesthetic protocol, and constant monitoring. The anesthetic protocol established in the present report was through pre-anesthetic medication with acepromazine, ketamine, and methadone. Anesthetic induction was performed with propofol and anesthetic maintenance through total intravenous anesthesia, using propofol, remifentanil, lidocaine, and ketamine, all in continuous infusion. As complementary analgesic therapy, a local block of the intercostal nerves was performed with bupivacaine. Transanesthetic monitoring was carried out with the aid of an electrocardiogram for cardiac assessment, pulse oximetry for oxygen saturation, capnograph for expired carbon dioxide fraction, non-invasive blood pressure, and invasive blood pressure. During the surgical procedure, the reported patient demonstrated few changes in parameters, with satisfactory results in the analgesic and anesthetic therapies instituted. There was a need for ventilatory support, which was provided through manual ventilation. Therefore, this work aimed to report the multimodal anesthesia of a patient diagnosed with pulmonary bleb who underwent the surgical procedure of pulmonary lobectomy, considering the anesthetic-surgical risks and addressing the clinical, diagnostic, and therapeutic aspects.
