Preterm birth is common, and population mobility has resulted in infants born prematurely away from home or being cared for in regional centers servicing more remote populations. Therefore many ex-preterm infants require transfer by air back home or to a step-down facility when tertiary medical services are no longer required. Consequently, air transfer of expreterm infants is routine. This is the first study to examine the effects in ex-preterm infants of low fraction of inspired oxygen (Fio2) during flight. Our results indicate that significant numbers (35%) of these infants require supplemental oxygen and have clinical signs and symptoms (15%). The decision to use supplemental oxygen based on Sp02 < 85% and the nursing responses to the clinical status of the infants in-flight were consistent with current practice guidelines for the general care of preterm infants in hospital.
Preterm infants are particularly vulnerable to hypoxia through mechanisms that include immature respiratory control and increased pulmonary vascular reactivity. Predicting which infants are most at risk for in-flight hypoxia is an important consideration when deciding whether an infant can safely fly or requires supplemental oxygen. Current guidelines- suggest the HCT as a means to determine safety to fly. We therefore compared results obtained using a standardized HCT with the observations made during the commercial flights taken by ex-premature infants. We observed that the 20-min HCT is not accurate for predicting in-flight oxygen needs in such infants. While the high false-failure rate might have logistic and financial implications, the greater concern was the high false-pass rate: 12 of 16 infants (75%) who had Sp02 < 85% and required oxygen during the flight had passed the HCT. Clearly, the HCT was not able to predict clinically significant oxygen desaturation in flight, and reliance on the HCT puts this population of infants at risk.
