What monitoring protocols should be followed for pregnant patients diagnosed with hypertension to ensure maternal and fetal safety?

For pregnant patients diagnosed with hypertension, conduct regular fetal ultrasound assessments for growth, amniotic fluid volume, and umbilical artery doppler velocimetry at diagnosis and at specified intervals: every 2 to 4 weeks for gestational hypertension, and at 28, 32, and 36 weeks for chronic hypertension ¹.

Carry out cardiotocography at diagnosis of pre-eclampsia or severe gestational hypertension, and only repeat if clinically indicated ¹.

In women with pre-eclampsia or severe gestational hypertension, perform ultrasound for fetal growth, amniotic fluid assessment, and umbilical artery doppler velocimetry at diagnosis, with subsequent scans every 2 to 4 weeks depending on findings ¹.

Monitor maternal blood pressure hourly during labour in women with hypertension, and every 15 to 30 minutes until blood pressure is less than 160/110 mmHg in cases of severe hypertension ¹.

Assess for symptoms of pre-eclampsia at each antenatal visit, including proteinuria testing via dipstick, and quantify if positive, using albumin:creatinine ratio or protein:creatinine ratio ¹.

Perform repeat biochemical and haematological tests (platelet count, transaminases, serum creatinine) 48-72 hours postpartum or after step-down from critical care, and repeat if abnormal ¹.
