A 3-month-old infant with recurrent apparent life-threatening events in a car seat.

Abstract

A 3-month-old infant was brought to clinic for evaluation of recurrent apparent life-threatening events (ALTEs). Two ALTE episodes occurred while the infant was sleeping in a safety car seat. The first one occurred when he was 4 weeks old. His mother noticed that he was not breathing; he appeared limp with full body cyanosis. His mother picked him up from the car seat, and he started breathing spontaneously and without any sign of distress. His skin color returned to normal. He was evaluated at the ED where the physical examination was normal. He was hospitalized 1 day for observation. During this time, workup, including ECG and chest radiograph, was normal. The parents were instructed on cardiorespiratory resuscitation and recommended to change car seats. The infant was discharged with an apnea monitor. He wore the apnea monitor while in the car seat. A second similar episode occurred at 10 weeks of age for which he was seen at the ED and referred to our clinic for further evaluation. Neither episode was related to feeding.
