The thoracoscopic sympathectomy procedure requires several anesthetic considerations that include an anesthesiologist and operating room staff familiar with thoracic endoscopy. Double-lumen endotracheal tube placement is needed for ventilation of the contralateral lung and active deflation of the ipsilateral lung. Care must be taken to ensure adequate inflation of the lung on the operated side before proceeding to the contralateral side because there have been both published and anecdotal reports of adverse cardiac and cerebral intraoperative events secondary to hypoxia from presumed hypoventilation.
The choice whether to use carbon dioxide insufflation versus ambient pressure coupled with lung deflation and a fan refractor is surgeon specific. There are case reports of intraoperative cardiac arrest requiring resuscitation when carbon dioxide insufflation was used, with speculation that an increased mediastinal or intrathoracic pressure resulted in a decreased stroke volume and subsequent arrhytmia.
