In reviewing the adverse outcomes in pregnancies complicated by polyhydramnios,
we found the overall incidence of polyhydramnios to be 1.8% in our population.
Of those who were included in our study group,
80% were considered to have mild polyhydramnios,
17.6% of the cases were considered moderate,
and 2.4% were considered severe. This is similar to Barnhart’s study,
which noted polyhydramnios in 1.7% of 2,730 pregnancies.
