Cardiac arrest during pregnancy: ongoing clinical conundrum

Area of Science:

• Obstetrics and Gynecology
• Emergency Medicine
• Cardiology

Background:

• Maternal mortality is rising in the US despite global decreases.
• Complex factors include socioeconomic issues, healthcare access, disparities, comorbidities, and ascertainment bias.
• Clinician preparedness for maternal cardiac arrest is critical.

Purpose of the Study:

• To outline essential components of maternal cardiac arrest management.
• To highlight the need for specialized interventions beyond standard resuscitation.
• To identify areas for future research in maternal resuscitation.

Main Methods:

• Review of current guidelines and best practices for maternal cardiac arrest.
• Emphasis on interdisciplinary team approach and understanding pregnancy physiology.
• Integration of standard basic and advanced cardiac life support with pregnancy-specific maneuvers.

Main Results:

• Management requires addressing aortocaval compression via left lateral uterine displacement.
• Perimortem delivery is indicated if circulation is not restored within 4 minutes in advanced pregnancy.
• Additional interventions like cardiopulmonary bypass may be necessary.

Conclusions:

• Maternal cardiac arrest necessitates a tailored approach, deviating from nonpregnant protocols.
• Simulation and team training are vital for institutional readiness.
• Further research is needed to optimize specific interventions and establish a comprehensive database.
