Quantitative fetal heart rate evaluation without pattern classification: FHR score and artificial neural network analysis

摘要

Fetal heart rate (FHR) monitoring, used by us in Kyushu University in the 1960s Maeda et al. (1969), led to a reduction in the incidence of severe neonatal asphyxia, which in turn unmasked underlying neonatal intrinsic disorders, and facilitated the studies on congenital diseases. In the 1970s, in a controlled study at Tottori University, perinatal deaths were reduced by the use of fetal monitoring (Maeda 1979). In addition, in the 1970-1980s, the use of full intrapartum monitoring resulted in the reduction of neonatal asphyxia, perinatal deaths and cerebral palsy at Yohka General Hospital, where the cesarean section rate was only 10% (Tsuzaki et al. 1990).
