ballottement
Pronunciation: bal-OT-ment
Physical examination technique where gentle pressure causes the fetus to move away and then return, indicating adequate amniotic fluid.
Full Definition
Ballottement is a clinical examination technique used to assess fetal mobility and amniotic fluid volume during pregnancy. The examiner applies gentle pressure to the maternal abdomen, causing the fetus to move away from the examining hand and then bounce back when pressure is released. This sign indicates the presence of sufficient amniotic fluid around the fetus. The technique can be performed both externally through the maternal abdomen or internally during vaginal examination. Loss of ballottement may suggest oligohydramnios or a very large fetus with limited space for movement.
Usage
Usage note: French origin term; distinguish from general fetal movement or quickening.
