Background: The preeclampsia/eclampsia is one of the most serious condition peculiar to pregnancy, which defined as occurrence of hypertension, proteinuria in pregnancy and convulsion in eclamptic women. There are major risk for eclamptic and pre eclamptic women due to maternal and fetal complications.

Materials and Methods: In a prospective study, preeclamptic and eclamptic patients who were visited at Shariati hospital were divided into two groups due to having proper prenatal care or not. Maternal and fetal complication were studied in that two group. Maternal variables were included: incidence of preterm labor, eclampsia, mode of delivery, long term hospitalization, need for ICU, need to antihypertensive drugs over postportum, insistence of hypertension up to 6 weeks, postpartum trombocytosis, incidence of cesarean section due to abruptio placenta and IUGR, elevation of serum creatinine, incidence of HELLP syndrome and death of mother fetal variables were included incidence of IUGR and IUFD, pre term delivery and for need NICU. Relationship of demographic characteristics such as maternal age, parity, educational level, mode of delivery, presence of underlying disease, and educational level of person who referred the patient were studied.

Results: These variables except of educational level, and referral level were there was statistically significant difference between incidence of all of variables, in exception of mode of delivery. That means incidence of complications is lower in group with adequate prenatal care. Conclusion: It seems that adequate pernatal care can reduce or obligate maternal and fetal complication in hypertensive disorders in pregnancy.
