Inhaled nitric oxide for a severe respiratory syncytial virus infection in an infant with bronchopulmonary dysplasia
Abstract
Objective: To report the first case of ARDS in children treated with nitric oxide (NO) inhalation.
Methods: A 13-months infant presented with BPD and severe hypoxemia related to RSV infection and ARDS. Inhaled NO was delivered in the ventilatory circuit of a continuous flow ventilator (Babylog 8000, Dräger) in a concentration of 20-80 ppm for 7 days. NO and NO2 were continuously monitored (Polyton Draeger). Respiratory mechanics were evaluated by using the method of passive inflation by the ventilator.
Results: NO inhalation improved oxygenation (tcSaO2) and reduced respiratory system resistance without affecting arterial pressure. NO2 level remained below 5 ppm, and methaemoglobin level below 1%. The child survived without neurologic sequela.
Conclusions: Two mechanisms to explain oxygenation improvement can be suggested: selective improvement in perfusion of ventilated regions and bronchodilation.
