Summary
Objective:
To compare the effect of inhaled nitric oxide (iNO) combined with conventional mechanical ventilation (CMV) or high-frequency oscillatory ventilation (HFOV) on oxygenation and ventilation parameters, complications rates and mortality in newborns with acute hypoxic respiratory failure (AHRF).
Design:
A prospective observational study.
Setting:
The Paediatric Anaesthesia and Intensive Care Clinic, University Hospital Brno, and The Paediatric and Adolescent Medicine Clinic, General University Hospital, Prague.
Materials and methods:
We enrolled in the study newborns with persistent pulmonary hypertension (PPHN) or acute respiratory distress syndrome (ARDS) without congenital heart disease in whom CMV or HFOV had failed. The newborns were divided in the CMV or HFOV groups according to the type of ventilation during iNO therapy. We recorded the following characteristics: the demographic data, duration of hospitalization, mechanical ventilation and iNO therapy, ARDS origin, diagnosis, outcome, iNO concentration; oxygenation, ventilation and acid-base parameters, ventilator settings and complications due to iNO.
Results:
We enrolled 25 newborns. We recorded a temporary improvement in oxygenation in both the groups and in particular in the HFOV group. We did not record any improvement in the ventilation and acid-base parameters. We did not observe an effect on the ventilator settings except for a comparable decrease of FiO2 in both the groups. We did not record any adverse effects. Total mortality was 4%.
Conclusion:
Both the therapeutic combinations improve oxygenation in the newborns with AHRF. HFOV has an additive effect on oxygenation. Either combination did not influence the ventilation or acid-base parameters. Both the methods provided for a similar reduction of FiO2 with no effect on the other ventilator settings. We observed the same low probability of adverse effects of administering iNO up to 20 ppm in both combinations. Either combination did not influence the mortality in neonates with AHRF.
