Preeclampsia can also occur in the postpartum period or after delivery. There are currently no clear definitions or guidelines for postpartum preeclampsia, but experts have proposed a definition of new-onset preeclampsia that occurs between 48 hours after delivery up to 6 weeks after delivery.

While seizures are most common in the third trimester, they may occur any time from 20 weeks of pregnancy until 6 weeks after birth. [50] Because pre-eclampsia and eclampsia are common conditions in women, eclampsia can be assumed to be the correct diagnosis until proven otherwise in pregnant or postpartum women who experience seizures.

Preeclampsia superimposed on chronic hypertension occurs when a pregnant woman with chronic hypertension develops signs of pre-eclampsia, typically defined as new onset of proteinuria ≥30 mg/dL (1+ in the dipstick) in at least 2 random urine specimens that were collected ≥4 h apart (but within a 7-day interval) or 0.3 g in a 24-h period. [19]
Pre-eclampsia is a disorder of pregnancy in which there is high blood pressure and either large amounts of protein in the urine or other organ dysfunction. Pre-eclampsia is routinely screened for during prenatal care. Onset may be before, during, or rarely, after delivery. Around 1% of women with eclampsia die. [medical citation needed]
There is no clear first-line tocolytic agent. [6] [7] Current evidence suggests that first line treatment with β 2 agonists, calcium channel blockers, or NSAIDs to prolong pregnancy for up to 48 hours is the best course of action to allow time for glucocorticoid administration.
The exact cause of spontaneous preterm birth is difficult to determine and it may be caused by many different factors at the same time as labor is a complex process. [ 25 ] [ 26 ] The research available is limited with regard to the cervix and therefore is limited in discerning what is or is not normal. [ 12 ]
Pre-eclampsia Pre-eclampsia is gestational hypertension plus proteinuria (>300 mg of protein in a 24-hour urine sample). Severe pre-eclampsia involves a blood pressure greater than 160/110, with additional medical signs and symptoms. HELLP syndrome is a type of pre-eclampsia.
Pre-eclampsia also doubles the risk of death of the baby around the time of birth. [25] Usually there are no symptoms in pre-eclampsia and it is detected by routine screening. When symptoms of pre-eclampsia occur the most common are headache, visual disturbance (often "flashing lights"), vomiting, pain over the stomach, and swelling .
