fetal scalp electrode
Also written as: FSE
Internal monitoring device attached directly to the fetal scalp to obtain continuous, high-quality fetal heart rate tracings.
Full Definition
A fetal scalp electrode (FSE) is an invasive monitoring device consisting of a small spiral electrode that is screwed into the fetal scalp to provide direct fetal electrocardiogram monitoring. This method offers superior signal quality compared to external Doppler monitoring, particularly useful during active labor when external monitoring may be inadequate due to maternal movement or obesity. FSE placement requires ruptured membranes and adequate cervical dilation, and carries small risks of fetal infection or scalp injury.
Usage
Usage note: Commonly abbreviated as FSE; requires informed consent due to invasive nature.
