Innovative Use of Pulmonary Artery (PA) Catheter for Lung Isolation in a Pediatric Patient: A Case Report

Lung isolation is essential for optimal surgical exposure and prevents contamination of normal lung. It is challenging in pediatric patients due to the anatomical and physiological differences. The most common methods of achieving lung isolation include the use of double-lumen endotracheal tubes (DLTs) or bronchial blockers (BBs). However, in pediatric patients, the size of the airways often restricts the use of DLTs, and in some cases, specific BBs may not be available or feasible due to the anatomy. Here, we report a case of right lower lobectomy in a two-and-half-year-old child using a pulmonary artery (PA) catheter to isolate the lung.
