Obstetric factors in the causation of early periventricular--intraventricular hemorrhage

On routine fontanelle scanning of neonates weighing less than or equal to 2000 g within the first 24 hours of life, 21% had abnormal findings related to peri/intraventricular hemorrhage. These findings occurred almost exclusively in patients who were in labor, with one exception, and were not observed without labor. Once labor ensued, the performance of cesarean section did not prevent periventricular and intraventricular hemorrhage. Other obstetric factors including fetal heart rate monitoring and umbilical artery pH values were not related to early periventricular and intraventricular hemorrhage. The practical significance of these findings is discussed.
