In-flight deaths of babies are rare but researchers say they've found that lap infants may be at greater risk of death on commercial flights than other babies.
The study analyzed pediatric medical emergencies on flights worldwide between January 2010 and June 2013 and found 90 percent of deaths occurred in children under the age of 2.
"The pattern we identified in our analysis is intriguing and could indicate lap infants are at greater risk of death related to in-flight environmental factors such as sleeping arrangements," says Alexandre Rotta, MD, Chief, Division of Pediatric Critical Care Medicine at

Could have gone unnoticed
The pattern would have gone unnoticed through single case analysis of these relatively rare events, Rotta said. Rotta was the lead investigator on the study, which was conducted at University Hospitals Rainbow Babies & Children's Hospital in Cleveland.
The study was conducted in partnership with MedAire to characterize the rare event of an in-flight pediatric fatality onboard commercial airline flights worldwide. Through a detailed analysis of more than 7,000 reported medical emergencies involving children (newborn to age 18) over a three-year period, researchers found death most commonly occurred in previously healthy children under the age of 2, and in children with a preexisting medical condition.
The fatalities were identified by searching records of all in-flight medical emergencies for child passengers that were reported to MedAire, which provides ground-based medical support to commercial airlines worldwide.
Of the 7,573 reported emergencies, 10 resulted in death, and six had no previous medical history. Four passengers had preflight medical conditions, including two children traveling for the purpose of accessing advanced medical care.
Rotta speculates these infants were at increased risk from exposure to a hypoxic cabin environment, or by sharing a seat with an adult and co-sleeping during a long flight, but there could also be another yet unknown factor.
The majority of pediatric in-flight emergencies are related to infections, neurological conditions, and respiratory issues such as asthma, seldom require alteration of flight route and do not pose significant risk to life. Because an in-flight pediatric death is such a rare event, large datasets were necessary to capture a meaningful number of observations.
"I hope our findings lead to further research on this important subject," Rotta said. "It is my belief the pattern we discovered should promote the development of preventative strategies and travel policies to protect the health of all pediatric airplane passengers, especially infants."
The study was published in the Pediatric Critical Care Medicine Journal.
