Obstetrics and Gynecology Board Review Pearls of Wisdom

124 Obstetrics and Gynecology Board Review •••


❍ What percentage of eclamptic seizures occur in late postpartum eclampsia (beyond 48 hours postpartum but
<4 weeks)?
25% (attributed to improved prenatal care).


❍ Is fetal bradycardia following a seizure an indication for a stat cesarean?
No. Fetal bradycardia is common after a seizure due to maternal hypoxemia and lactic acidemia. This usually
resolves after 3 to 5 minutes of intrauterine resuscitation. If persistent over 10 minutes, then an imminent delivery
must be considered, as it may indicate other complications such as placental abruption.


❍ What patterns of fetal heart rate may be noted during and after a seizure?
Bradycardia, transient late decelerations, and decreased beat-to-beat variability.


❍ Name the maternal complications that may follow a seizure.
Pulmonary edema, aspiration pneumonitis, cerebral hemorrhage resulting in hemiplegia or sudden death,
blindness, psychosis, placental abruption, DIC, acute renal failure, and cardiopulmonary arrest.


❍ What is the rate of preeclampsia in a subsequent pregnancy after eclampsia in the index pregnancy?
25%.


❍ What is the rate of recurrent eclampsia?
2%.


❍ What are the diagnostic criteria of HELLP syndrome?
