AUCKLAND, New Zealand, Dec. 8 -- When infants take lengthy naps in child safety seats, the babies may risk life-threatening oxygen desaturation, according to a small study.
Among 43 infants in New Zealand who had a-life threatening event during over 18 month, nine cases were due to oxygen desaturation and secondary central apnea while sleeping in a child safety seat, said Alistair Jan Gunn, M.B., Ch.B., Ph.D., of the University of Auckland, and colleagues, reported online in BMJ.
The researchers prospectively examined all cases referred to the Auckland Cot [crib] Monitoring Service, which follows up on apparently life threatening events that occur to young infants.
All infants had turned blue or pale at least once, and the caregivers thought the child had stopped breathing. Nine were restrained at the time in an appropriate car seat, of which eight were rear-facing and semi-reclining, the researchers said.
