[Intrapartum amnio-infusion in patients with oligohydramnios]

Patients with oligohydramnios are at increased risk of developing fetal distress during labor, presumably as the result of umbilical cord compression. Intrapartum saline amnio-infusion for short-term amnionic fluid replacement was performed in a prospective randomized manner in 60 cases of oligohydramnios during period of 1-year. Patients receiving amnio-infusion had significantly lower incidence of neonatal asphyxia and less cesarean sections as compared with the controls. No neonatal nor maternal complication occurred. The effect of amnio-infusion was also confirmed by B type ultrasonic examination. These results suggested that intrapartum saline amnio-infusion might be a hopeful therapy for patients with oligohydramnios.
