Is Low Amniotic Fluid Cause for Induction?
A recent post on Lamaze International’s Science and Sensibility (great blog!) examined low amniotic fluid as a cause for induction. Author Rebecca Decker of Evidence-Based Birth found that:
- Ultrasound measurement is a poor predictor of actual amniotic fluid volume;
- The single deepest pocket method of measurement has fewer risks than the AFI (amniotic fluid index);
- Poor outcomes seen with low amniotic fluid are usually due to underlying complications such as pre-eclampsia, birth defects, or fetal growth restriction;
- The main risk of low amniotic fluid at term in a healthy pregnancy is induction (and cesarean delivery as a result of the induction), and potentially the risk of a low-birth-weight infant; and
- Current evidence does not support induction for isolated oligohydramnios at term.
