Abnormalities of respiratory regulation, such as apnea and abnormal hypoxic arousal during sleep, are mechanistic in the pathophysiology of SIDS. In utero cocaine exposure is associated with poor head growth, abnormal neurodevelopment, and an increased incidence of sudden, unexplained death, suggesting that in utero cocaine exposure disrupts the central regulation of breathing. It is likely that this disruption is due to altered CNS maturation. Indeed, cocaine alters norepinephrine metabolism within the locus coeruleus, important in arousal from sleep, suggesting that the increased incidence of SIDS in cocaine exposed infants may be secondary to sleep-related deficits in arousal. Since components of fetal behavioural state organization reflect the successful integration of the Central Nervous System, have a specific developmental timetable, and can be studied by fetal ultrasound techniques, we developed a strategy for assessing the state organization of the fetus by ultrasound techniques. We hypothesize that fetal evaluation of state will be a marker of abnormal CNS maturation and a predictor of risk, i.e. abnormal neurodevelopment and/or state related arousal deficits predisposing the cocaine exposed neonate to SIDS. We propose that the study of in utero cocaine exposed fetuses will provide a human model for examining the pathophysiology of SIDS.
