A2 - Grichnik, Katherine Y1 - 2012 N1 - T2 - Thoracic Anesthesia AB - The patient with an anterior mediastinal mass who undergoes general anesthesia is at risk of developing severe perioperative complications, including complete airway obstruction, severe hypoxemia, profound hypotension, and cardiac arrest.Predictors of perioperative complications in these patients include significant respiratory symptomatology at baseline, greater than 50% tracheal narrowing on CT scan, pericardial effusion, and SVC syndrome.The basic tenets of anesthesia for these patients include preservation of spontaneous breathing, securing the airway beyond the point of obstruction, the ability to rapidly change the patient's position, and preparation of options for managing emergencies, including rigid bronchoscopy, helium-oxygen gas mixture and CPB.
