Perimortem caesarean deliveries

Area of Science:

• Obstetrics and Gynecology
• Emergency Medicine
• Perinatology

Background:

• Cardiac arrest during pregnancy is a rare but critical event impacting maternal and fetal outcomes.
• Historically, perimortem cesarean delivery was performed late, leading to poor survival rates.
• Current evidence suggests rapid intervention may improve survival for both mother and fetus.

Purpose of the Study:

• To review the evidence and physiological rationale for perimortem cesarean delivery in pregnant patients.
• To discuss factors influencing timely intervention, including training and hospital organization.
• To emphasize the importance of perimortem cesarean delivery in managing maternal cardiac arrest.

Main Methods:

• Review of historical case reports and recent literature on perimortem cesarean delivery.
• Analysis of physiological benefits of rapid perimortem cesarean delivery.
• Discussion of error reduction and delay minimization strategies.

Main Results:

• Case reports indicate improved maternal and fetal survival with rapid perimortem cesarean delivery.
• Physiological advantages include relieving inferior vena cava obstruction, improving venous return, and enhancing chest compliance.
• No evidence suggests worsened maternal or fetal survival with early perimortem cesarean delivery.

Conclusions:

• Early perimortem cesarean delivery is likely beneficial for both maternal and fetal survival in cases of cardiac arrest from mid-second trimester.
• Effective management requires adequate training, optimized hospital protocols, and prompt decision-making.
• Perimortem cesarean delivery remains a critical intervention for maternal arrest during pregnancy.
