Even at the busiest medical centers, this will only total a few cases per year. Most of what we know regarding cardiopulmonary resuscitation (CPR) in pregnancy is based on animal experiments or observational studies in humans. There are no published randomized controlled clinical trials of CPR during pregnancy and few clinicians have had the experience of running many obstetrical codes. The mortality of obstetrical arrest is over 90% in some studies.
