    Summary

    Controlled supplemental oxygenation effectively prevents hypoxia during tracheobronchial hygiene in premature infants. This method, without manual ventilation, also reduces recovery time from hypoxemia, improving patient outcomes.

    Area of Science:

    • Neonatal Medicine
    • Respiratory Physiology

    Background:

    • Tracheobronchial hygiene is crucial for mechanically ventilated infants.
    • Hypoxemia can occur during these procedures, necessitating careful management.

    Purpose of the Study:

    • To evaluate the efficacy of controlled supplemental oxygenation without bag ventilation during tracheobronchial hygiene.
    • To compare oxygenation levels and recovery times between supplemental oxygenation and no oxygenation.

    Main Methods:

    • A randomized crossover study involving 16 premature infants on mechanical ventilation.
    • Transcutaneous partial pressure of oxygen (TcPO2) was monitored during two procedures: no oxygen (A) and controlled supplemental oxygen (B).
    • In Procedure B, FiO2 was adjusted to maintain TcPO2 between 90-100 torr.

    Main Results:

    • Both procedures showed a decrease in TcPO2 during chest vibration and suctioning.
    • Procedure B (supplemental oxygen) maintained significantly higher TcPO2 levels compared to Procedure A (no oxygen).
    • Mean recovery time from hypoxemia was significantly shorter in Procedure B (2.1 min) than in Procedure A (4.9 min).

    Conclusions:

    • Controlled supplemental oxygenation without manual bag ventilation is sufficient to prevent hypoxia during tracheobronchial hygiene in most infants.
    • This approach also accelerates recovery from hypoxemia, enhancing patient safety.
