Risk of fetal infection from invasive procedures.
Recent technological advances have led to the development of several types of invasive procedures in the fetus principally for the diagnosis and management of fetal disorders. The risk of infection to the fetus related to these procedures needs evaluation. Although there are few reports of fetal infection, proper infection control procedures must be observed because the most common consequence of infection is fetal loss. Fetal blood sampling in the presence of chorioamnionitis is a risk factor that warrants prophylactic antibiotics. Conversely, clinical specimens taken from the fetus in the absence of chorioamnionitis are more likely to become contaminated with maternal skin flora, and a positive fetal blood culture is not necessarily significant. There is probably a small but finite risk of transmission of maternal viral infections such as human immunodeficiency virus, hepatitis B and C, cytomegalovirus and herpes simplex during invasive procedures. Obstetric departments undertaking invasive fetal diagnosis and treatment must have an adequate policy for infection control procedures.
