In Reply.—Dr Greathouse expresses frustration with two areas of SIDS research that we share: (1) the cause of SIDS remains poorly understood, and (2) monitoring of infants has had little, if any, impact on reducing the incidence of SIDS.
Not understanding the cause(s) of SIDS, we must agree with Dr Greathouse that the term near-miss SIDS, which is used to describe episodes of apnea, cyanosis, and lack of tone, may be a misnomer. However, because of our lack of knowledge in this area, we are not ready to agree with Dr Greathouse's statement that "an SID is an SID is an SID," which, we feel, suggests a common pathophysiologic mechanism for all cases of SIDS.
Our premise that infants with histories of blue spells requiring intervention are at increased risk for SIDS is well supported,1-4 and our own experience in the intensive care nursery has convinced us that
