Nitric oxide administration using an oxygen hood: a pilot trial.

ABSTRACT:

Background

We have shown earlier that inhaled nitric oxide (iNO) administered by oxygen hood reduces pulmonary hypertension in an animal model (J Perinatol 2002; 22:50-6). Our objective in this study was to determine feasibility of iNO by oxygen hood in neonates with elevated alveolar-arterial oxygen gradients (A-aDO(2)).

Methods/principal findings

Masked randomized controlled pilot trial. Inclusion criteria were: gestation>or=34 weeks, age<7 days, with post-ductal arterial line, and A-aDO(2) 400-600. Infants were randomized to study gas (iNO 20 ppm or equivalent O(2) flow) for 1 hr which was then weaned over the next 4 hours. Primary outcome was PaO(2) one hour post-randomization. Four infants each were randomized to iNO or O(2) (controls). Two of the four infants given iNO
