Key result
Pregnancy-adapted resuscitation for maternal cardiac arrest requires salvage cesarean delivery after 4 minutes of failed efforts.
Why the study?
Maternal cardiac arrest is rare but life-threatening, with specific physiological considerations and management challenges during pregnancy.
Highlights the critical need for modified resuscitation protocols and timely salvage cesarean delivery in cases of maternal cardiac arrest.
Supports modified resuscitation protocols in maternal arrest; leaves open prospective validation of timing and outcomes.
The incidence of maternal cardiac arrest ranges from 1/55,000 to 1/12,000 births. It is due most frequently to cardiovascular, hemorrhagic, and anesthesia-related causes, as well as to amniotic fluid embolism. The basic principles of resuscitation remain applicable in this situation, but the physiological modifications of pregnancy must be taken into account, in particular, the aortocaval compression syndrome. After 24 weeks of gestation, a salvage cesarean delivery must be performed immediately, without transfer to the operating room, if resuscitation maneuvers have failed 4 min after arrest, because this interval conditions the mother's neurological prognosis and improves neonatal survival.

Fischer et al. (2019) conducted a review in Maternal cardiac arrest. Resuscitation and salvage cesarean delivery was evaluated. In-hospital maternal cardiac arrest requires standard resuscitation principles modified for pregnancy, including immediate salvage cesarean delivery if resuscitation fails after 4 minutes.
