[Home monitoring of apnea in children at increased risk for sudden infant death (SIDS)].

Since 1981, 96 infants considered at increased risk of SIDS underwent home monitoring for prolonged sleep apnea: 23 infants after a near miss for SIDS event, 28 siblings of a SIDS victim and 45 infants with a variety of perinatal risk factors. For a total of 65 infants the course of home monitor surveillance was completed by September 1984 with a duration ranging from 6 to 15 month: 26% (4/15) of the near miss for SIDS group, 23% (3/13) of the SIDS siblings and 13% (5/37) of the perinatal risk cases developed more than one prolonged apneic episode with additional symptoms requiring vigorous intervention by parents. Two infants of the perinatal risk group became SIDS victims: despite an apnea alarm after 15 seconds the parents were unable to resuscitate their infant in one case, the other died from SIDS about 4 month after monitoring was discontinued because of an uneventful course and normal polygraphic sleep recordings The large number of prolonged apneas requiring intervention and the two SIDS cases (3% of the total study group) indicate a considerably increased risk of prolonged life-threatening sleep apnea and SIDS in the population monitored.
