[Anesthetic managements of premature triplets for PDA ligation through median sternatomy].

Extreme premature triplets were scheduled for PDA ligation through median sternatomy. Anesthesia was maintained with fentanyl, ketamine, pancuronium and sevoflurane or isoflurane with N2O, oxygen and air. During operation, steady ventilation with low oxygen concentration was maintained. Monitoring size and contraction of hearts in the face, 5% albumine solution could be administered safely for hypotension after PDA ligation. PDA ligation through median sternatomy might be a less invasive surgical procedure.
