Historically, there has been very limited data regarding the epidemiology of OHCA in pregnant females. Two recently-published studies tried to shed some light on the issue.
Both Maurin et al.1 and Lipowicz et al.2 looked at all-cause out-of-hospital maternal cardiac arrest (MCA) data in terms of numbers and management, in Paris and Toronto respectively, from 2009/2010 to 2014. Collectively, they found:
A few reminders from the 2015 AHA guidelines for the management of cardiac arrest in pregnancy:
Bottom Line: Although maternal cardiac arrest is relatively rare, survival in OHCA is lower than perhaps previously thought. Areas to improve include public education on the importance of bystander CPR in pregnant females, and appropriate physician adherence to PMCS recommendations, with decreased on-scene time by EMS in order to decrease time to PMCS.
Maurin et al. looked at documented out-of-hospital maternal cardiac arrest (MCA) in pregnant females ≥18 years old, in Paris from 2009 to 2014 and reported on some aspects of prehospital care. Prehospital management there includes activation of both a BLS (which usually arrives first) and ALS team, with a prehospital emergency physician being a member of the ALS team.
Lipowicz et al. similarly looked at MCA from 2010 to 2014 using data from the Toronto Regional RescuNet cardiac arrest database:
