Hypertension in pregnancy

There are CKS guidelines on management of Hypertension in Pregnancy (including post partum follow-up).

Pre-eclampsia

Please see the CKS guidelines on managing women at high risk of, or exhibiting clinical features of pre-eclampsia (1)

Prescribing aspirin for women assessed to be at high risk of pre-eclampsia:

Refer for consultant-led care at booking for specialist input to assess and manage the obstetric risk.
Ensure that aspirin 75—150 mg daily is prescribed from 12 weeks' gestation until birth. This is usually arranged in secondary care, but should be initiated in primary care if the woman will not be seen by a specialist until after 12 weeks.
- Seek specialist advice before prescribing aspirin to girls younger than 16 years of age, and in those with thrombophilia or uncontrolled blood pressure. There is no evidence that use of low-dose aspirin in pregnancy is associated with an increased risk of congenital abnormalities or other fetal complications. (1)

Referral

Please see the Maternity Services section for advice on how to refer.

Postpartum Hypertension

Please see the CKS guidelines below for advice on management during the postpartum period:

Postpartum follow-up | Management | Hypertension in pregnancy | CKS | NICE

The guideline gives the following advice about follow up of this group of patients:

Reduce antihypertensive treatment if blood pressure falls below 130/80 mmHg..
Review antihypertensive treatment 2 weeks postnatally.
Ensure that women with chronic hypertension are offered a medical review 6–8 weeks after the birth either in primary care, or with a specialist as appropriate.

The Remedy team are not aware of any more specific national or local guidelines about how to wean anti-hypertensive medication and suggest a pragmatic approach using the above as a guide.
