High Frequency Oscillatory Ventilation (HFOV) and Inhaled Nitric Oxide (iNO) Use During Neonatal Emergency Transport – Feasibility and Efficacy in India

A retrospective study of 24 neonates to evaluate the feasibility and efficacy of high frequency oscillatory ventilation (HFOV) and inhaled nitric oxide (iNO) for transferring critically ill neonates to tertiary neonatal intensive care, who were transported by road ambulance was done. Efficacy was measured by clinical improvement, patient safety was assessed by comparing cardiorespiratory indicators before and after transport, and adverse events during transport. Significant oxygenation improvement was observed in neonates transported with HFOV ± iNO compared to earlier ventilator settings. Pre- and post-transport vital signs were stable, and no transport-related deaths occurred. A substantial rise in median SpO₂ was seen after transfer [86 (81, 91) vs. 93 (89, 97) before transport, p <0.001]. Twelve of twenty-one newborns who received nitric oxide demonstrated significant improvement in oxygenation index (a 10% decrease from prior value). Overall survival was 70.8%, however non-transfer or inadequate respiratory treatment may have exacerbated mortality.
