Altered anesthetic requirements and carbon dioxide setpoint in chronic airway obstruction

Abstract

Accidental ingestion of a foreign body into either tracheobronchial tree or esophagus is not an uncommon occurrence. However, there is limited literature available on sequelae of post foreign body ingestion—carbon dioxide set point and apneic threshold due to chronic respiratory acidosis. We report a case of chronic airway obstruction in a 14-month-old boy with prior history of battery ingestion and share our experience in the management.
