When should resuscitative cesarean delivery (RCD) be performed in a pregnant patient?

Resuscitative cesarean delivery (RCD) is indicated in emergency scenarios involving a pregnant patient who experiences cardiac arrest, particularly when rapid delivery is crucial for the survival of the fetus. The correct timing for RCD is within five minutes from the time of arrest. This time frame is critically important because fetal outcomes are significantly better if the delivery occurs promptly. After five minutes, the fetal risk for hypoxia and other complications increases markedly.

In cases of maternal cardiac arrest, performing a cesarean delivery within this time frame allows for the restoration of blood flow and oxygenation to the fetus, which can be vital for its survival. This urgency is emphasized in resuscitation protocols for pregnant patients, where both the mother and fetus need to be considered.

While performing the procedure as soon as possible can be beneficial, the emphasis on a five-minute window is supported by the need to optimize conditions for the fetus and minimize the risks associated with prolonged lack of oxygen.
