Transporting premature neonates in prone or prone-free positions may improve oxygenation by 8% compared to the supine position. However, this study found no statistically significant difference in arterial oxygen tension among these positions during air transport.

Area of Science:

  • Neonatal intensive care
  • Transport medicine
  • Respiratory physiology

Background:

  • Critically ill premature neonates often require specialized transport.
  • Maintaining adequate oxygenation during transport is crucial for patient outcomes.
  • The impact of patient positioning on oxygenation during air transport is not well-established.

Purpose of the Study:

  • To evaluate the effect of body positioning on arterial oxygen tension in premature neonates during air transport.
  • To compare oxygenation levels in supine, prone, and prone-free positions.
  • To determine if positioning changes significantly impact oxygenation in this vulnerable population.

Main Methods:

  • A study involving 24 critically ill, premature neonates undergoing air transport.

  • Participants had endotracheal tubes and umbilical artery catheters, and evidence of hyaline membrane disease.
  • Arterial oxygen tension was measured in supine, prone, and prone-free positions during transport.

    • Main Results:

    • An average 8% increase in oxygenation was observed in the prone and prone-free positions versus the supine position.
    • This observed increase, while potentially clinically relevant, did not reach statistical significance.
    • No statistically significant difference in arterial oxygen tension was found among the three tested positions.

    Conclusions:

    • While prone positioning may offer a trend towards improved oxygenation in premature neonates during transport, it did not yield statistically significant results in this study.
    • Further research with larger sample sizes may be needed to confirm clinical significance.
    • Positioning strategies during neonatal air transport warrant continued investigation.
