  Purpose
This research project is an open-label, randomized study for the use of Nitric Oxide in pediatric patients with acute respiratory distress syndrome (ARDS). The study examines whether nitric oxide (NO) treatment impacts the the P:F ratio (arterial partial pressure of oxygen (PaO2) divided by fraction of inspired oxygen (FiO2) in patients with ARDS. The goal of the study is to evaluate whether the order of NO therapy will have any effect on response, and evaluate the characteristics of patients who respond to NO compared to those who do not.

Primary Outcome Measures:
  • Mean PaO2/FiO2 Ratio [ Time Frame: 8 hours ]
    Arterial blood gas measurements with cooximetry to evaluate arterial partial pressure of oxygen (PaO2) and fraction of inspired oxygen (FiO2) ratio. The mean PaO2/FiO2 ratio for each group after completion 8 hour of study participation was compared

Arms Assigned Interventions
Active Comparator: Nitric oxide first
Subjects will be randomized to receive Nitric Oxide (NO) immediately after study entry, given at 10 parts per million (ppm) for the first 4 hours of study participation. Blood gases will be monitored once an hour for 4 hours. After the first 4 hours of study participation, the nitric oxide (NO) will be turned off and subjects will receive no intervention (no nitric oxide) for the next 4 hours of study participation. During this time, all subjects will receive standard clinical are. Blood gases will be monitored once an hour for 4 hours.
Drug: Nitric Oxide
Subjects will receive inhaled Nitric Oxide at a dose of 10 parts per million (ppm) for a 4 hour study period. Blood gases will be collected once an hour.
Other Name: Inhaled Nitric Oxide
Other: No Intervention
Subjects will receive no intervention (i.e., no nitric oxide treatment) for a 4 hour study period. Blood gases will be collected once an hour. During this time, all subjects will receive standard clinical care.
Active Comparator: Delayed nitric oxide
Subjects will be randomized to receive no intervention (no nitric oxide) for he first 4 hours of study participation. During this time, all subjects will receive standard clinical care. Blood gases will be monitored once an hour for 4 hours. After the first 4 hours of study participation, the nitric oxide will be turned on and subjects will receive 10 ppm of nitric oxide for the next 4 hours of study participation. Blood gases will be monitored once an hour for 4 hours.
Drug: Nitric Oxide
Subjects will receive inhaled Nitric Oxide at a dose of 10 parts per million (ppm) for a 4 hour study period. Blood gases will be collected once an hour.
Other Name: Inhaled Nitric Oxide
Other: No Intervention
Subjects will receive no intervention (i.e., no nitric oxide treatment) for a 4 hour study period. Blood gases will be collected once an hour. During this time, all subjects will receive standard clinical care.

Detailed Description:

At low concentrations, nitric oxide(NO) functions as a cellular messenger and regulator of microcirculation. NO may have an important role in the pathogenesis of ARDS as well as its treatment. NO may be primarily useful in improving matching of ventilation and perfusion in the lung. The aims of the study are to attempt to show that NO will improve oxygenation as evidenced by improvement in PaO2/FiO2. Secondary aims are to see if the improvement in oxygenation allows there to be decreased time on FiO2>0.60, evaluate whether the order of NO therapy will have any effect on response, and evaluate the characteristics of patients who respond to NO compared to those who do not.

Subjects will be randomized to receive either nitric oxide first (nitric oxide for the first 4 hours, then no intervention/no nitric oxide for the next 4 hours) or delayed treatment with nitric oxide (no intervention/no nitric oxide for the first 4 hours, then nitric oxide for the next 4 hours)..

Blood gases were monitored once an hour during study participation (total of 8 hours). Final PaO2/FiO2 levels will be compared after 8 hours of study treatment in each group.
