The diagnostic accuracy of mean arterial pressure in second trimester for prediction of preeclampsia in females.

Abstract

Objective: To assess the diagnostic accuracy of mean arterial pressure in second trimester for prediction of pre-eclampsia in females. Study Design: Cross-sectional study. Setting: Department of Obstetrics & Gynecology Unit III, Allied hospital, Faisalabad. Period: October 2016 to September 2017. Material & Methods: Total 386 patients were enrolled after obtaining informed consent. Booked females of age 18-40 years, parity<5 presenting at gestational age >16 weeks (on LMP) for antenatal checkup were included in study. Patients with multiple gestation (on medical record and USG), Females with chronic hypertension (BP≥140/90mmHg), chronic or gestational diabetes (BSR>186mg/dl), Females having oligohydramnios (AFI<5cm) or polyhydramnios (AFI>21cm) on USG, females having abnormal placental implantation or placental abruption (on USG) were excluded. The mean age of the patients was 28.59±6.93 years. The MAP of the patients was 94.88±14.68 mmHg. Results: The sensitivity, specificity and diagnostic accuracy of MAP was 92.89%, 89.12% and 91.45% respectively taking preeclampsia as gold standard. Conclusion: The mean arterial pressure in second trimester is very effective and useful screening method for prediction of preeclampsia with high values of sensitivity, specificity and diagnostic accuracy.
