Neonatal high-frequency jet ventilation: four years' experience.

S J Boros, M C Mammel, J M Coleman

    Summary

    High-frequency jet ventilation (HFJV) improved outcomes for neonates with severe pulmonary air leaks and congenital diaphragmatic hernias. However, prolonged HFJV use was linked to tracheal injury, necessitating further research on risks and benefits.

    Area of Science:

    • Neonatal Medicine
    • Pediatric Critical Care
    • Respiratory Physiology

    Background:

    • Severe respiratory distress in neonates, including pulmonary air leaks and congenital diaphragmatic hernias, presents significant management challenges.
    • High-frequency jet ventilation (HFJV) is an advanced respiratory support technique used in critical neonatal cases.

    Purpose of the Study:

    • To evaluate the efficacy and safety of high-frequency jet ventilation (HFJV) in neonates with severe pulmonary air leaks, congenital diaphragmatic hernias, and end-stage respiratory failure.
    • To compare the performance of two different HFJV systems in these patient populations.

    Main Methods:

    • A retrospective analysis of 34 neonates treated with two different HFJV systems over a 4-year period.
    • Assessment of patient outcomes including arterial blood gas values, survival rates, and tracheal histopathology.

    Main Results:

    • HFJV improved arterial blood gas values in 82% of patients, with an overall survival rate of 32%.
    • In neonates with pulmonary air leaks, 74% improved and 39% survived.
    • Prolonged HFJV (≥8 hours) in deceased patients was associated with significant tracheal histopathology, including necrotizing tracheobronchitis.

    Conclusions:

    • HFJV demonstrates utility in managing severe neonatal pulmonary air leaks and potentially congenital diaphragmatic hernias.
    • HFJV is associated with inflammatory tracheal injuries, particularly with prolonged use.
    • Further clinical and laboratory investigations are required to fully elucidate the risk-benefit profile of HFJV in neonates.
