Anesthetic Management for Concomitant Correction of Congenital Cardiac Defects and Long "O" Ring Tracheal Stenosis: A Role for Heliox?: Report of 2 Cases.

ABSTRACT

We present 2 infants with the rare association of long congenital tracheal stenosis, ventricular septal defect, and pulmonary hypertension. We describe a step-by-step assessment of the patients and the necessary procedures for a successful concomitant repair of both cardiac and tracheal malformations. The use of a helium-oxygen mixture (heliox) for the induction of anesthesia and pre-cardiopulmonary bypass is discussed.
