A review of 24 consecutive sudden infant deaths was undertaken to eval
uate the importance of the various stages in the postmortem assessment
of such cases. Death in three cases was caused by obvious trauma. Of
the remainder, 16 were attributed to sudden infant death syndrome (SID
S), 4 to accidental asphyxia (identified by death scene examination an
d/or formal case review) and 1 to a lingual thyroglossal duct cyst. Th
ree (14%) of 21 deaths thought to be SIDS after postmortem examination
were attributed to asphyxia following subsequent formal case review.
