This is an iatroX educational summary of named Australia sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Apply current TGA product information, PBS restrictions, state or territory law, local referral criteria, formulary and antimicrobial policy. A national recommendation does not create uniform service access.

Scope

Measure blood pressure accurately and assess gestation, previous readings, symptoms and urine protein; pregnancy-specific thresholds and pathways apply. Evaluate headache, visual symptoms, epigastric or right-upper-quadrant pain, dyspnoea, oedema change and fetal wellbeing for pre-eclampsia and severe disease. This summary is limited to the population, decisions and escalation boundaries stated in the named source.

The Bottom Line

  • Measure blood pressure accurately and assess gestation, previous readings, symptoms and urine protein; pregnancy-specific thresholds and pathways apply.
  • Evaluate headache, visual symptoms, epigastric or right-upper-quadrant pain, dyspnoea, oedema change and fetal wellbeing for pre-eclampsia and severe disease.
  • Chronic hypertension, gestational hypertension and pre-eclampsia are distinct diagnoses with different maternal and fetal surveillance.
  • Order the maternity pathway laboratory assessment for platelets, liver and kidney involvement and quantify proteinuria where indicated.

Practical clinical workflow

1

Topic-specific assessment action

Measure blood pressure accurately and assess gestation, previous readings, symptoms and urine protein; pregnancy-specific thresholds and pathways apply.
2

Topic-specific diagnostic action

Order the maternity pathway laboratory assessment for platelets, liver and kidney involvement and quantify proteinuria where indicated.
3

Topic-specific management action

Use only pregnancy-compatible antihypertensive treatment from the current Australian maternity guideline and coordinate obstetric review and fetal surveillance.
4

Topic-specific follow-through

Advise ongoing postpartum pressure monitoring because pre-eclampsia can first present or worsen after birth.

Safety boundaries and escalation

  • Severe pressure, neurological symptoms, pulmonary oedema, eclampsia, HELLP features or fetal compromise requires immediate maternity emergency transfer.
  • After recovery, document increased lifetime cardiovascular risk and arrange primary-care blood pressure and risk-factor follow-up.

Implementation

The named source is national or binational guidance used in Australia, but referral access, public-health directions, formularies and funded services can still differ by state, territory and health service. Check current TGA product information for medicines. Offer culturally safe care and use the NACCHO鈥揜ACGP National Guide where Aboriginal and Torres Strait Islander preventive or chronic-care recommendations differ.
