[Anesthetic management of a 1.7-kg premature infant undergoing thoracoscopic thoracic duct ligation].
We report successful anesthetic management of a 1.7-kg premature infant who underwent thoracoscopic thoracic duct ligation under general anesthesia. She was born at 30 weeks gestation with birth weight of 1,546 g and was suffering from respiratory distress due to persistent right chylothorax for two months after birth. Chest tube drainage, fasting and intrapleural fibrin glue did not reduce her right chylothorax. Thoracoscopic thoracic duct ligation was scheduled on her day 64 under general anesthesia. The tracheal tube end was placed in the midtrachea and carbon dioxide was insufflated into the operative side of the thorax. During thoracoscopy her left lung was ventilated with the right lung pressed with spatulaes, but her respiratory status did not deteriorate so much despite of unilateral ventilation. We speculate that, due to massive right chylothorax, her pulmonary blood flow had already shifted to the left lung, therefore intraoperative substantial left unilateral lung ventilation exerted minimal effect on her respiratory status. The operation was successful and she was weaned from the ventilator on the following day.
