Pregnancy induced hypertension causes and treatments

Hypertension is the most common medical problem encountered in pregnancy and remains an important cause of maternal, and fetal, morbidity and mortality. The hypertensive disorders of pregnancy cover a spectrum of conditions, of which pre-eclampsia poses the greatest potential risk and remains one of the most common causes of maternal death in the UK.

This reduction in blood pressure primarily affects the diastolic pressure and a drop of 10 mm Hg is usual by 13—20 weeks gestation. After this, there is a gradual increase in blood pressure until term when pre-pregnancy levels are attained.

Immediately after delivery blood pressure usually falls, then increases over the first five postnatal days.

However, it should be recognised that blood pressure is gestation related. A diastolic blood pressure of 90 mm Hg is 3 standard deviations SD above the mean for mid pregnancy, 2 SD at 34 weeks, and 1. Blood pressure must be elevated on at least two occasions and measurements should be made with the woman seated and using the appropriate cuff size.

Late in the second trimester and in the third trimester, venous return may be obstructed by the gravid uterus and, if supine, blood pressure should be taken with the woman lying on her side. Korotkoff phase I and V disappearance should be used, rather than phase IV mufflingsince it is more reproducible 2 and shows better correlation with true diastolic blood pressure in pregnancy.

Automated systems for blood pressure measurement have been shown to be unreliable in severe pre-eclampsiaw3—4 and tend to under record the true value.

Undiagnosed hypertensive women may appear normotensive in early pregnancy because of the normal fall in blood pressure, commencing in the first trimester.

This may mask the pre-existing hypertensionw5 w6 and when hypertension is recorded later in the pregnancy it may be interpreted as gestational. Sometimes the diagnosis is only made several months post partum, when the blood pressure fails to normalise as would be expected with gestational hypertension.

Furthermore, pre-eclampsia can rarely present before 20 weeks gestation and may be misinterpreted as chronic hypertension. Gestational hypertension Hypertension occurring in the second half of pregnancy in a previously normotensive woman, without significant proteinuria or other features of pre-eclampsia, is termed gestational or pregnancy induced hypertension.

Pre-eclampsia and eclampsia Pre-eclampsia usually occurs after 20 weeks gestation and is a multi-system disorder. Oedema is no longer included because of the lack of specificity. Eclampsia is defined as the occurrence of a grand mal seizure in association with pre-eclampsia, although it may be the first presentation of the condition.

An estimated 50 women die annually from pre-eclampsia worldwide 9 and morbidity includes placental abruption, intra-abdominal haemorrhage, cardiac failure, and multi-organ failure.

In the last confidential enquiry into maternal deaths there were 15 confirmed deaths from pre-eclampsia or eclampsia, the majority as a result of intracerebral haemorrhage.Gestational hypertension, also referred to as pregnancy induced hypertension (PIH) is a condition characterized by high blood pressure during pregnancy.

Gestational hypertension can lead to a serious condition called preeclampsia, also referred to as toxemia. Hypertension during pregnancy affects.

Symptoms. Preeclampsia sometimes develops without any symptoms. High blood pressure may develop slowly, or it may have a sudden onset.

Monitoring your blood pressure is an important part of prenatal care because the first sign of preeclampsia is commonly a rise in blood pressure. Doctors can’t yet identify one single cause of preeclampsia, but some potential causes are being explored.

These include: genetic factors; Other treatments during pregnancy. Hypertensive disorders of pregnancy, including preeclampsia, complicate up to 10% of pregnancies worldwide, constituting one of the greatest causes of maternal and perinatal morbidity and mortality worldwide.
