    Summary

    High-frequency jet ventilation (HFJV) successfully treated neonates with severe respiratory failure due to air leaks. However, prolonged HFJV use in newborns may risk airway obstruction.

    Area of Science:

    • Neonatal Medicine
    • Pediatric Pulmonology
    • Critical Care

    Background:

    • Intractable respiratory failure in neonates often stems from pulmonary air leaks.
    • Conditions like bronchopleural fistulas and pulmonary interstitial emphysema pose significant challenges.

    Purpose of the Study:

    • To evaluate the efficacy and safety of high-frequency jet ventilation (HFJV) in neonates with intractable respiratory failure.
    • To assess HFJV's impact on pulmonary air leaks and gas exchange.

    Main Methods:

    • Ten neonates with intractable respiratory failure were treated using HFJV.
    • Pulmonary air leaks, oxygenation (PaO2/FIO2), and carbon dioxide levels (PaCO2) were monitored.
    • Duration of HFJV and incidence of airway complications were recorded.

    Main Results:

    • HFJV reduced pulmonary air leaks in 7 of 9 neonates.
    • Oxygenation (PaO2/FIO2) improved in 80% of patients (P < .05).
    • Carbon dioxide levels (PaCO2) decreased in 90% of patients (P < .01).
    • Five neonates survived the treatment.
    • Three of six patients receiving HFJV >20 hours developed tracheal obstruction.

    Conclusions:

    • HFJV can be an effective ventilation strategy for neonates with respiratory failure caused by pulmonary air leaks.
    • Long-term HFJV use in neonates carries a risk of airway obstruction and damage.
