Dengue hemorrhagic fever during pregnancy: antepartum, intrapartum and postpartum management.

Dengue hemorrhagic fever is a common tropical disease in Thailand that nowadays has an increasing incidence during adulthood. We managed three cases of dengue hemorrhagic fever during pregnancy which developed during the antepartum, intrapartum and postpartum periods. We diagnosed dengue hemorrhagic fever during pregnancy with clinical pictures of fever, hemoconcentration and thrombocytopenia with serological proof in all cases. All cases were treated conservatively except for the second one, in which cesarean delivery was inevitable due to severe preeclampsia with unfavorable cervix. All patients and their babies were in good condition before discharge. With increasing incidence during adulthood, more cases of dengue hemorrhagic fever in pregnancy can be found. Conservative treatment should be conducted in all cases. We believe that this is the first case report of intrapartum dengue hemorrhagic fever during pregnancy.
