From the Guidelines

Postpartum eclampsia can occur up to 10 days after delivery, with a recommended observation period of 72 hours in the hospital and 7-10 days postpartum for individuals with gestational hypertension, preeclampsia, and superimposed preeclampsia. This condition is characterized by seizures in women who have developed preeclampsia during pregnancy or after childbirth. The observation window is crucial for healthcare providers to recognize symptoms like severe headache, visual disturbances, upper abdominal pain, and swelling that may develop even after hospital discharge 1. Treatment typically includes magnesium sulfate for seizure prevention and antihypertensive medications like labetalol or hydralazine for blood pressure control, and close monitoring.

  • Key factors to consider in postpartum eclampsia management include:
    • Blood pressure observation for 72 hours in the hospital and 7-10 days postpartum 1
    • Long-term follow-up for individuals with gestational hypertension, preeclampsia, and superimposed preeclampsia due to increased lifetime cardiovascular risk 1
    • Awareness of symptoms like severe headache, visual disturbances, upper abdominal pain, and swelling that may develop even after hospital discharge
  • The pathophysiology involves persistent endothelial dysfunction and inflammatory responses that can continue well beyond delivery, making awareness of this vulnerability period crucial for prompt recognition and treatment of warning signs. Women with a history of preeclampsia during pregnancy are at highest risk, and healthcare providers should prioritize their care accordingly 1.

From the Research

Postpartum Eclampsia Window

  • The postpartum eclampsia window is a period of time after delivery when a woman is at risk of developing eclampsia, which is the onset of seizures in a woman with preeclampsia 2, 3.
  • According to the studies, eclampsia that occurs more than 48 hours after delivery is considered late-onset postpartum eclampsia, and it is rare, constituting 16% of all cases of eclampsia 2.
  • The postpartum eclampsia window can last up to 6 weeks after delivery, with most women presenting with new-onset hypertension and severe features within the first 7 to 10 days after delivery 3.
  • However, there have been cases reported of postpartum eclampsia occurring as late as 8 weeks after delivery, highlighting the importance of considering this diagnosis even several weeks after delivery 4.
  • The duration of magnesium sulfate treatment for postpartum eclampsia can vary, with some studies suggesting that shortened treatment protocols may be as effective as traditional 24-hour treatment in preventing seizures and total complications 5, 6.
