Summary

Inhaled nitric oxide (iNO) improves oxygenation in term infants with respiratory failure. However, iNO has been primarily used in infants receiving mechanical ventilation. This study is a pilot study to determine if iNO given into an oxygen hood is effective in improving oxygenation in term and near-term infants who have poor oxygenation but who are not yet mechanically ventilated.

Conditions

Interventions

DRUG

inhaled Nitric Oxide

iNO started at 20 ppm for 1 hour, then weaned hourly over the next 4 hours (20 ppm to 10 to 5 to 2.5 to 1 to off). If \>5% drop in oxygen saturation was observed during weaning, study gas was increased to the previous concentration and weaning done 2 hourly. If \> 5% drop in oxygen saturation or \>5% Methemoglobin was observed during initial administration, the study gas would be weaned over 30 minutes and the infant would exit. The iNO was introduced into an oxygen hood (Oxydome ™ disposable hood from Maxtex ® Inc.) using an INOvent (Datex-Ohmeda). The INOvent ® was connected to the oxyhood by placing the injector module inline on the dry side of the humidifier chamber. Monitoring of O2, NO2, NO was done by placing the end of the sample line inside the oxyhood. A "Masking Shield" covered the Display/Control Panel and Cylinder Gauges, in order to maintain masking of the intervention. Only the respiratory therapist and research coordinator was aware of the allocation assignment.

DRUG

Oxygen (>90% by hood) - standard therapy

Oxygen (\>90% by hood, standard therapy for PPHN prior to intubation) was introduced into an oxygen hood (Oxydome ™ disposable hood from Maxtex ® Inc.) using an INOvent (Datex-Ohmeda). The INOvent ® was connected to the oxyhood by placing the injector module inline on the dry side of the humidifier chamber. If the baby was randomized to the control group and did not receive NO, the INOmax® cylinder was opened and used only to pressurize the system, which prevented the "Low NO Pressure" alarm. A "Masking Shield" covered the Display/Control Panel and Cylinder Gauges, in order to maintain masking of the intervention. Only the respiratory therapist and research coordinator was aware of the allocation assignment.
