amniotomy
Pronunciation: am-nee-OT-uh-mee
Artificial rupture of the fetal membranes performed to induce or augment labor.
Full Definition
Amniotomy is the deliberate rupture of the amniotic membranes using a sterile instrument, typically performed to initiate or accelerate labor. This procedure allows assessment of amniotic fluid color and volume, may strengthen uterine contractions, and facilitates internal fetal monitoring. Amniotomy should only be performed when the fetal head is engaged and the cervix is partially dilated to minimize cord prolapse risk. The procedure requires sterile technique and immediate assessment for cord presentation. Documentation must include membrane integrity, fluid characteristics, and fetal response.
Usage
Usage note: Document the indication, technique, and immediate findings including fluid characteristics.
