Inhaled nitric oxide (NO) as a complementary treatment was studied in 10 neonates during extracorporeal membrane oxygenation (ECMO) therapy of various persistent pulmonary hypertension of the newborn (PPHN)-associated diseases. At individually different levels of inhaled NO (20-80 ppm), the mean PaO-2 increased by 59.7% in 6 responders, but it remained unchanged in 4 nonresponders. Adverse side effects of the NO inhalation were tolerable. It was associated with a reversible decrease of the mean arterial blood pressure in 1 patient. During prolonged NO inhalation, the methemoglobin (met-Hb) level increased to 0.9-4.6% in 6 patients. Based on these preliminary results, we conclude that inhaled NO during ECMO can improve oxygenation in some PPHN patients. Further studies with control groups are needed to determine whether inhaled NO can shorten ECMO treatment or improve the rate of survival among PPHN patients.
