Polyhydramnion. A clinical study.

A clinical study of pregnancies complicated by polyhydramnion diagnosed at the Department of Obstetrics and Gynaecology, University of Oulu, during 1972--1976 is presented. The incidence of polyhydramnion was 0.4% and it was associated with premature delivery, multiple pregnancy, chemical diabetes, and foetal anomalies. However, there were no anomalies in 2/3 of the newborn infants. The perinatal mortality was 41.7%. Early diagnosis is important in order to give good antenatal care and to plan for the delivery. The importance of ultrasonic examination in prenatal diagnosis is stressed.
