What next?

Conclusions• Hypertensive disorders complicating pregnancy are one of the major

causes of maternal and foetal mortality and morbidity.

• Early diagnosis and management can help in circumventing many of the

complications of the same.

• Both labetolol and methydopa have been recommended as first-line

drugs in various studies. Final use depends on a careful assessment of risk

benefit ratio and clinician judgement.

• Nifidipine sustained release should be used as a second line drug and

SUBLINGUAL NIFIDIPINE should NEVER be used.

Conclusions• Watch for and screen for pre-ecclampsia in high risk individuals at regular

intervals.

• Test of choice for proteinuria is an automated reagent strip reading device or

urinary spot protein:creatinine ratio.

• Aspirin is the ONLY PROVEN method of primary prevention of hypertensive

disorders in high risk individuals.

• Patient counselling and education regarding nature of illness and informed

consent prior to initiating treatment is mandatory.

• With early detection and appropriate management, the journey with

hypertension can be made a smooth one for both mother and child.
