Gastrointestinal hemorrhage induced by percussive ventilator in an infant with chronic lung disease complicated after surgery for corrected transposition of the great arteries

: A newborn patient (birth weight 2,332 g) with corrected transposition of the great arteries developed chronic lung disease due to a severe heart failure and post operative several complications. We applied intrapulmonary percussive ventilation (IPV) to the patient. IPV improved oxygenation concomitant with the improvement of respiratory condition and chest X-ray finding. However, the patient suffered from upper gastrointestinal bleeding 15 days after initiation of IPV therapy. The bleeding was healed several days after temporal termination of IPV, but recurred with resuming IPV therapy. The patient was irritable throughout the IPV therapy, and thus gastrointestinal bleeding of the patient could be due to stress induced by IPV therapy. IPV may be useful for the management of respiratory disturbance, often observed in low birth weight patients with congenital heart defects. However, gastrointestinal bleeding may occur and should be considered as a possible complication associated with IPV therapy.
