The Physiological Impact of Neonatal Air Transport: A Review of The Literature

Abstract

Objective

This review aims to enhance our understanding around whether neonatal air transport has an adverse physiological impact on patients.

Methods

A literature search included articles describing both ground and air transport. Eligible studies had to include patient outcome and/or response to the journey in such a way that the physiological impact of neonatal transport could be compared between the 2 groups.

Results

The search produced 13 eligible studies. Six were prospective observational cohort studies, and the remainder were retrospective. When assessing outcome, studies used a physiological stability score, the rate and severity of intraventricular hemorrhage, the type and frequency of clinical interventions during the journey, or a specific clinical parameter. Three of the studies sought to understand the physiological impact of transport by investigating the variation in the physical forces experienced.

Conclusion

The current published evidence does not suggest one mode of transport is preferable to another when considering patient stability and outcome. Neonatal fixed wing or helicopter transport has not been shown to be more physiologically challenging for the patient than road transport, even by teams who are regularly flying patients in the highest-risk groups (extremely preterm, in the first hours of life).
