Does approximate entropy of fetal heart rate variability predict fetal distress in women at term pregnancy?
Effect estimate: likelihood ratio 12.301
p-value: p=< 0.001
Approximate entropy of fetal heart rate variability is significantly correlated with umbilical blood gas parameters and may serve as a predictor of fetal distress and metabolic acidosis at term pregnancy.
Li et al. (2005) conducted an observational in Fetal distress (n=67). Low approximate entropy (ApEn < 1.0) of fetal heart rate variability vs. High approximate entropy (ApEn ≥ 1.0) was evaluated on Metabolic acidosis (base excess < -12 mmol/l) (likelihood ratio 12.301, p=< 0.001). Low approximate entropy (ApEn <1.0) of fetal heart rate variability was associated with a higher risk of metabolic acidosis compared to high ApEn (likelihood ratio 12.301, P<0.001).
