Educational Objectives

Medical: 
  1. Recognize and manage cardiac arrest in pregnant patients
  2. Identify need for perimortem CS
  3. Perform perimortem CS

Communication:

  1. Communicate emergent need for perimortm CS to team leader
  2. Consult NICU and OB stat

Case Synopsis

28 year old female, 37 weeks pregnant, BIBEMS after high speed MVC. Pt was a restrained driver in a head-on collision with a tree. Estimated speed at impact was 75 mph. The car was completely damaged with spider webbing of the windshield. Pt was responsive to pain but was not oriented in the field. EMS noted a protuberant abdomen. Upon arrival in the ED, her initial GCS was 5 (abnormal flexion to pain with decorticate response), it is noted that the pt becomes pulseless within 5 minutes of arrival to the ED and has an asystolic cardiac arrest.

  2. Initiate ACLS on asystolic cardiac arrest
  3. Identify pregnant pt with uterine fundus greater than 20 cm above pubic symphysis
  4. Initiate and complete perimortem CS within 5 minutes loss of pulses
