Answer

The diagnosis of clinical chorioamnionitis in pregnancy is commonly made based on clinical findings of fever plus fetal tachycardia, maternal leukocytosis, or purulent fluid coming from the cervical os. Additionally, the pregnant woman with chorioamnionitis may appear ill, even toxic, and she may exhibit hypotension, diaphoresis, and/or cool or clammy skin. However, especially when dealing with histologic chorioamnionitis, maternal clinical signs or symptoms of infection may be absent (silent chorioamnionitis). [5]

Furthermore, clinical signs and symptoms of chorioamnionitis are not always associated with placental evidence of inflammation. [6] This is particularly true if maternal fever is the sole criterion for the diagnosis.
