摘要

The need for one-lung ventilation has been increasing even in pediatric patients. However, the trachea is so narrow in pediatric patients that ordinary double-lumen tubes can not be used and there have been many reports on devices or measures to block one lung. We report our experience with a female infant weighing 2 kg who had severe chronic lung disease under mechanical ventilation, and underwent left lung lower lobectomy with one-lung ventilation technique. We chose a balloon wedge pressure catheter to block the left main bronchus, because it has a central lumen through which a guide wire can be passed and sucking is available. The infant was in need of continuous ventilation and the catheter was too soft to be inserted directly. We first inserted an 18G catheter of a needle-catheter assemble outside the tracheal tube through which a guide wire was inserted into the left main bronchus with the aid of direct vision of a 2-mm fiberoptic bronchoscope through the tracheal tube, and then inserted the balloon wedge pressure catheter placing it in an appropriate position. One-lung ventilation was successfully achieved and the operative and postoperative course was uneventful.
