The early detection of the risk of PE may improve the outcome by increasing patient surveillance or by initiating a therapeutic intervention. After taking family history and medical history of obstetric events, hypertension, renal disease, or thrombophilia can help to stratify the risk of hypertensive disorders of pregnancy and history alone will identify fewer than half the women who later develop pre-eclampsia. Routine screening for specific risk factors for pre-eclampsia i.e. nullipara, older age, high body mass index (BMI), family history of pre-eclampsia, multiple pregnancy, more than 10 years between pregnancies, and a personal history of pre-eclampsia is advised.
MATERIAL AND METHODS:Detail history of all the participants was taken which comprises of age, parity, and past obstetric complications. Medical history was taken and pregnant ladies. Blood pressure measurement was done by standard mercury sphygmomanometer. Mean arterial pressure was calculated by Burton’s formula. Waist circumference was measured midway between the lowest rib and the iliac crest. Waist circumference of >80 cm was used as a cut off.
RESULTS: Majority of the patients who developed pre eclampsia were in the age group of 20 to 25 years (66%).in our study primigravida were 60% who developed pre eclampsia. In our study 40 (20%) had mean arterial pressure >90 mmHg 22 developed preeclampsia while out of 160 (80%) patients having mean arterial pressure 80 cm out of 80 women 34 developed preeclampsia while 52 were normotensive. Out of 114 women having waist circumference <80 cm 12 developed preeclampsia while 102 remain normotensive with sensitivity, specificity, positive predictive value and negative predictive value of 73.91%, 66.23%, 39.53% and 89.47% respectively.
CONCLUSION: Mean arterial pressure is a good predictor of preeclampsia with high specificity and negative predictive value. Waist circumference is a simple, and reproducible method with high negative predictive value.
