Large mediastinal tumor in a neonate: an anesthetic challenge.

Mediastinal tumors pose a grave risk of cardiopulmonary complications during the perioperative course, particularly in neonates and small children. These tumors can cause displacement and compression of vital thoracic structures such as the tracheobronchial tree, the heart, and the great vessels. Catastrophic complications often occur during induction of anesthesia, use of muscle relaxants, positioning, and at the time of extubation. We present our experience of anesthetic management of a neonate with a mediastinal mass who had features of both airway and vascular obstruction.
