Influence on clinical practice of routine intra-partum fetal monitoring.

Perinatal mortality fell significantly from levels in preceding years to 15-8 and 11-7 per 1000 births, respectively, in 1973 and 1974, due to the elimination of intra-partum still births and a significant reduction in neonatal mortality.

Abstract

An attempt has been made to monitor by continuous fetal heart rate according all women admitted in labour. Altogether 85% of the 1070 patients delivered at one hospital were monitored in 1973 and 92% in 1974. Perinatal mortality fell significantly from levels in preceding years to 15-8 and 11-7 per 1000 births, respectively, in 1973 and 1974. The fall was primarily due to the elimination of intra-partum stillbirths and a significant reduction in neonatal mortality. The incidence of caesarean sections also fell from 9-7% in 1973 to 5-8% in 1974. All patients should be monitored because it is impossible to predict reliably intra-partum fetal distress from maternal "high-risk" factors present before the onset of labour.
