ballottement
Pronunciation: bal-OT-ment
A clinical technique used to assess fetal mobility within the amniotic fluid by applying gentle pressure to the maternal abdomen.
Full Definition
Ballottement is a physical examination technique performed during pregnancy to evaluate fetal position and mobility. The examiner applies a gentle, quick tap or push to the maternal abdomen, causing the fetus to move away and then return to its original position, creating a sensation of the fetus 'floating' or 'bouncing back.' This technique is particularly useful in the second trimester when amniotic fluid volume is optimal. Ballottement can help confirm fetal viability, assess fetal size relative to gestational age, and evaluate amniotic fluid volume. The technique requires sufficient amniotic fluid (normal or increased) to be effective.
Usage
