Measurements should be confirmed by repeated readings over several hours. Elevations of both systolic and diastolic blood pressures have been associated with adverse fetal outcome and therefore both are important. Disorders associated with hypertension such as eclampsia and preeclampsia are further characterised by symptoms such as proteinuria, oedema or high body temperature. There are several reasons to support the blood pressure readings defined above as diagnostic of hypertension in pregnancy:
This definition of hypertensive disorder in pregnancy from the Society of Obstetric Medicine in Australia and New Zealand (SOMANZ) aligns with the definition of the International Society for the Study of Hypertension in Pregnancy (ISSHP). |
