Department of Maternal Fetal Medicine

Osaka Women’s and Children’s Hospital was established in 1981 as a specialized hospital for mothers and children. Since then, we have been engaged in medical care and research of mother and fetus as a core facility of maternal and child health and medical care in Japan. 
We work on medical care and health guidance for pregnant women who are outpatients to our department. We also provide 24-hour support of maternal transfer and obstetric emergencies from local communities, and perform perinatal management for high-risk pregnancies.
Our hospital has a role as a core facility of OGCS (Obstetrics and Gynecology Cooperative System) in Osaka Prefecture. We accept obstetric emergency transfer from all over the prefecture and coordinate referrals between medical facilities. Our activities are not limited to Osaka Prefecture and we also collaborate nationwide. In addition, our department is willing to accept healthy pregnant women without complications and those who wish to give birth in Osaka.
We handle about 1600 deliveries per year. We handle not only low-risk pregnancies but also high-risk pregnancies with a variety of medical complications. We have several specialized outpatient clinics for high-risk pregnancies.

For low-risk pregnant women

“Low-risk pregnant woman” means those who is in healthy condition without any major illnesses. Nearly 70% of deliveries at our hospital are low-risk, and we provide general maternity checkups and deliveries for them. If a low-risk pregnant woman has some problems while their standard maternity checkups, we will treat her at a specialized outpatient clinic. Condition of pregnancy and delivery can change from low-risk to high-risk unexpectedly. Several obstetricians always stay at our hospital, and we cooperate with neonatologists and anesthesiologists who are available 24 hours.

Medical treatment data of our department

We handle more than 1600 deliveries annually including low-risk and high-risk pregnancy cases; about 300 preterm deliveries, about 120 deliveries of multiple pregnancy, about 160 deliveries with fetal congenital anomaly, and about 200 referral cases related to mother and fetus emergency. We have several specialized outpatient clinics for high-risk pregnancies. We also provide painless labor performed by anesthesiologists.
