Assessment of knowledge regarding cardiopulmonary resuscitation of pregnant women

Introduction

The 2000-2002 triennial UK Report on Confidential Enquiries into Maternal Deaths concluded that over 50% of maternal deaths involved substandard care and that many could have been prevented. Catastrophic events leading to cardio-respiratory arrest may necessitate the resuscitation of pregnant women in various hospital locations. This study was designed to evaluate knowledge about resuscitation of parturients among anesthesiologists, obstetricians and emergency physicians.

Methods

A 12-question survey was distributed anonymously to residents and faculty in the anesthesia (ANES), obstetrics (OB), and emergency medicine (EM) departments at Stanford University Medical Center/Lucile Packard Children’s Hospital, Stanford, California. Questions were designed to elicit knowledge deficiencies in four critical areas: need for left uterine displacement (LUD), advanced cardiac life support algorithms (ACLS), physiologic changes of pregnancy (PHYS), and the recommendation to perform cesarean delivery in parturients (>20 weeks gestation) after 4-5 min of unsuccessful resuscitation for cardiac arrest (5CD).

Results

In total, 74/75 physicians (43% ANES, 37% OB, and 20% EM) completed the test. ANES scored highest in overall test scores, and in knowledge of PHYS (P<0.05). Scores for LUD and 5CD were similar among groups, but 25-40% of these questions were answered incorrectly. In the ACLS category, the EM group scored highest (93%).

Conclusion

We conclude that knowledge of important basic concepts, including the need for LUD and the potential benefit of early cesarean delivery during cardiac arrest, is inadequate among all three specialties. All three departments should provide ACLS physician training with emphasis on the special considerations for parturients.
