RESUMO
<p><b>OBJECTIVE</b>To explore the clinical features and prognosis of early-onset preeclampsia.</p><p><b>METHODS</b>A total of 115 cases of early-onset preeclampsia were recruited from January 1999 to December 2004 and the data analyzed in terms of the incidence, manifestation, maternal and fetal complications.</p><p><b>RESULT</b>The early-onset preeclampsia accounted for 13.4% of all preeclampsia diagnosed. The perinatal mortality was 13.3% in early-onset preeclampsia. Dysfunction and hepatic dysfunction were the main maternal complications. The gestational ages at admission and at delivery were significantly correlated with perinatal prognosis (P<0.001). Most cases received regular treatment had good prognosis.</p><p><b>CONCLUSION</b>Early-onset preeclampsia is a severe type of preeclampsia.</p>
