To compare risk factors, biochemical parameters, maternal and fetal health parameters of Early onset preeclampsia and Late onset preeclampsia in Central India at tertiary care centre. Methods: At a tertiary care institute in Central India, a prospective study was conducted. 75 women in each, EOP and LOP, were studied based on development of preeclampsia before and after 34 weeks of gestation respectively. Risk factors, biochemical parameters, maternal and perinatal outcomes were compared between the groups to get a better idea in understanding etiopathogenesis and its implications on Indian Population. Results: The results concluded that Mean Gestational age in EOP was 31.8 weeks than 37.9 in LOP. 50.67% and 37.3% ICU admissions were seen in EOP and LOP respectively due to more incidence of maternal morbidities in EOP. In EOP and LOP still births were 21.3% and 9.3% respectively. More number of NICU admissions were seen in EOP than LOP; 30.7% and 8% respectively. Conclusion: The results concluded that Early onset preeclampsia is comparatively associated with more severe maternal and perinatal outcomes, which was statistically significant. Biochemical parameters were more deranged in Early onset preeclampsia. Inconclusive results were found on comparison of known risk factors of preeclampsia between both groups |
