[Are there pre- or perinatal risk factors for sudden infant death?]. / Gibt es prä-oder perintale Risikofaktoren für den plötzlichen Säuglingstod?

The question was posed, whether a relationship could be established between prenatal and perinatal events and subsequent sudden infant death. The birth records of eighty mothers, whose infants died of sudden infant death syndrome (SIDS) between 1982 and 1987, were reviewed for obstetric complications. The records immediately following the respective SIDS cases served as controls. A family history of SIDS was found significantly more often in the SIDS group than in the control group (p less than 0.001). Oxytocin was administered significantly more often in the SIDS group than in the control group: 54/80 (= 68%) and 20/80 (= 25%, p less than 0.001), respectively. Smoking, hypotension requiring treatment and the administration of tocolytic agents were found significantly more frequently in the SIDS group than in the control group (p less than 0.01, p less than 0.001, and p less than 0.05). Transient fetal hypoxia, as a result of reduced flow in the uterine artery, seems possibly to be connected to the vasoactive agent Oxytocin when occurring in the three above named groups. Whether these situations are connected to a later development of SIDS, has not, to date, been confirmed.
