Abstract: Sudden compound trauma can be life-threatening for a pregnant woman in her third trimester. In view of such rare emergencies, this paper tries to discuss how to rescue pregnant women and fetuses and when to periform a perimortem cesarean section based on the condition of the pregnant woman and the fetus, in order to provide more effective reference for similar cases in the future. This article suggests that if spontaneous circulation can not return after active and effective cardiopulmonary resuscitation, perimortem cesarean section should be considered. Further rescue after cesarean section is beneficial for both the mother and the fetus.

Key words: Perimortem cesarean section, First aid, Multiple trauma, Pregnant women, Fetus
