Abstract: A patient is presented in whom endotracheal intubation was impossible secondary to an obstructing substernal goiter and laryngeal spasm. Cardiopulmonary bypass was utilized to provide safe induction of anesthesia and intubation so that the substernal goiter could be removed. Other alternative methods in anesthetic management are discussed.
The impossible intubation--what next?
