Introduction: Hypertensive disorders complicating pregnancy are common and form one of the deadly triad, along with hemorrhage and infection that contribute greatly to maternal morbidity and mortality. Aim: To know the variation in platelet count between normal pregnancy and pregnancy induced hypertension (PIH) and correlate – fetomaternal outcome. Materials and Methods: It is prospective study done in 100 pregnant women attending the gyneacology ward. Among these 50 were normal pregnant women, 15 were eclampsia, 20 were preeclampsia (sever PIH) 15 were mild pregnancy induced hypertension from the antenatal clinic and inpatient ward. Results: More number of cases in eclampsia group came from rural area, from lower socio economic group and were unbooked for antenatal care. Both diastolic and systolic pressures are significantly correlating platelet count. Platelet count is significantly lower in cases of pre-eclampsia and eclampsia when compared to normal. Mean gestational period delivery was shorter in pre-eclampsia and eclampsia when compared to normal. Mean birth weight was reduced as the severity of the disease increased. Conclusions: Thrombocytopenia is directly proportional to the severity of the pre-eclampsia. Reduction of platelet count below 1 lac per ml. increases the risk of developing DIC and HELLp syndrome significantly, thus an early prediction suggesting prompt management.
