Objective. To compare the incidence of sudden infant death syndrome (S
IDS) and apparent life threatening event (ALTE) in infants with bronch
opulmonary dysplasia (BPD) and birth weight-matched control infants in
view of the changing pattern of chronic lung disease of prematurity.
Methods. The study population consisted of 78 preterm infants of 26 to
33 weeks gestation who were diagnosed as having BPD and discharged. T
he 78 control infants were matched with the study infants for birth we
ight categories. Infants unable to maintain adequate oxygenation witho
ut supplemental oxygen when they were feeding well and thriving were d
ischarged on home oxygen. All infants were at least 8 months of age at
follow-up and information concerning the occurrence of any ALTE was o
btained by direct parent interview. Results. No infant died during the
period of followup. Seven (8.9%) of the study group compared with eig
ht (10.5%) of the control infants had an ALTE. Three infants (one stud
y, two control infants) were hospitalized for further investigation. N
o infant discharged on the home oxygen program had an ALTE. Conclusion
s. The data from this study suggest that preterm infants with BPD are
not at increased risk from SIDS compared with preterm infants without
this condition. This may be related to close monitoring of the infants
' oxygenation status and the provision of home oxygen when appropriate
, which should eliminate episodes of unrecognized and untreated hypoxe
mia. Home monitoring for infants with BPD may not be warranted.
