Rarely, pre-eclampsia may begin in the period after delivery.[3] While historically both high blood pressure and protein in the urine were required to make the diagnosis, some definitions also include those with hypertension and any associated organ dysfunction.[3][9] Blood pressure is defined as high when it is greater than 140 mmHg systolic or 90 mmHg diastolic at two separate times, more than four hours apart in a woman after twenty weeks of pregnancy.[3] Pre-eclampsia is routinely screened for during prenatal care.[10][11] • Recommendations for prevention include: aspirin in those at high risk, calcium supplementation in areas with low intake, and treatment of prior hypertension with medications.[4][5] In those with pre-eclampsia delivery of the baby and placenta is an effective treatment.[4] When delivery becomes recommended depends on how severe the pre-eclampsia and how far along in pregnancy a woman is.[4] Blood pressure medication, such as labetalol and methyldopa, may be used to improve the mother's condition before delivery.[6] Magnesium sulfate may be used to prevent eclampsia in those with severe disease.[4] Bedrest and salt intake have not been found to be useful for either treatment or prevention.[3][4]
