An intentional opiate intoxication of an infant: when medical toxicology and child maltreatment services merge.

We present an instructive case of a 5-week-old infant seen in the emergency department with acute inspiratory stridor and depressed level of consciousness. His emergency department course identified an acute opiate intoxication. The child also developed chest wall rigidity, a rare complication of narcotic use. We discuss the emergency department management, as well as the toxicologic and child protection investigations.
