Key result
Reduced fetal heart rate variation (20.6 ms vs normal 44.4 ms) was associated with fetal hypoxaemia (mean umbilical artery PO2 6 mmHg) and nutritional deprivation, but not with asphyxia.
Why the study?
Does reduced antenatal fetal heart rate variation correlate with respiratory and metabolic status in compromised human fetuses?
Population
71 women delivered by caesarean section before labour, divided into three groups: abnormal fetal heart rate…

Reduced fetal heart rate variation in compromised fetuses is a marker of fetal hypoxaemia and nutritional deprivation rather than acute asphyxia.

Absolute Event Rate: 20.6% vs 44.4%
Reduced fetal heart rate variation in compromised fetuses is a marker of fetal hypoxaemia and nutritional deprivation rather than acute asphyxia.
Smith et al. (1988) conducted an observational in Compromised human fetus (n=71). Abnormal fetal heart rate trace (reduced FHR variation) vs. Normal fetal heart rate was evaluated on Fetal heart rate variation (mean range of pulse intervals in ms). Reduced fetal heart rate variation (20.6 ms vs normal 44.4 ms) was associated with fetal hypoxaemia (mean umbilical artery PO2 6 mmHg) and nutritional deprivation, but not with asphyxia.
