Infant Transition From Car Bed to Car Safety Seat
Infant Transition From Car Bed to Car Safety Seat
This research study has been developed to obtain preliminary information about safe timing of
 the transition of infants from car beds to car seats, and to find out if initial failure of
 the car seat challenge is associated with small jaw size or increased respiratory illness.
Studies show that car seats can directly reduce injury in motor vehicle accidents.
 Unfortunately, some premature and term infants have trouble breathing from the semi-upright
 seating position in car seats. As a result, the American Academy of Pediatrics recommends car
 seat challenge testing for at-risk infants, including all children born at less than 37 weeks
 gestation and other high risk newborns such as those with a history of breathing problems
 and/or low tone. Infants who fail the car seat test are discharged home in car beds. However,
 guidelines regarding timing of repeat car seat testing or safe transition back to a car seat
 are currently unavailable.

 At present there is no system for continued evaluation of infants sent home in car beds. In
 addition, it is not known when it is safe to transition infants from their car bed to a car
 seat. Infants transitioned too early may still have breathing problems and those transitioned
 too late may be at risk for injury in the event of a crash. Due to these reasons it is
 important to find out when it is safe to transition infants from the car bed to a car seat

 Moreover, it has recently been shown that some infants with apparent life threatening events
 (ALTE), have a smaller jaw size than their peers that did not have an ALTE. ALTEs can occur
 when infants are in their car seats. No studies have been found that looked to see if infants
 with breathing problems in their car seats also have small jaws. Furthermore no studies have
 looked to see if infants who fail their initial car seat challenge are at greater risk for
 respiratory illness during their first year of life.
