Toxicology and Sudden Infant Death

Abstract

One hundred thirty cases of sudden infant death occurring in Wayne County, Michigan, (population 2.7 million) were analyzed for possible drugs. The toxicological protocol has been outlined. Six cases were found to be positive, and in five of these the drugs found had been prescribed for a variety of illnesses. In one case methadone was found in the blood of an infant whose mother was undergoing methadone treatment for drug addiction, the drug being transmitted through breast milk. In none of the 102 cases of sudden infant death syndrome (SIDS) included in the study did the toxicological results affect the diagnosis. In our study, toxicological analyses never contradicted an initial diagnosis of SIDS, and, therefore, we feel that this diagnosis should be made promptly based on investigative and autopsy findings.
