Intrapartum Fetal Heart Rate Monitoring - Perinatology.com Continuous electronic fetal monitoring is the continuous monitoring of fluctuations of the fetal heart rate (FHR) in relation to maternal contractions and is considered standard practice during active labor.13 Continuous electronic fetal monitoring was developed for widespread use in the 1970s as a screening test for fetal hypoxia/acidosis during labor, specifically to reduce hypoxic-ischemic encephalopathy, cerebral palsy, and fetal death.13, Fetal acidemia (pH < 7.15) is most accurately diagnosed via umbilical cord arterial sampling immediately after delivery.46 Because fetal acidosis can affect autonomic control and therefore variability of FHR, continuous electronic fetal monitoring is considered a surrogate marker for measurement.2,7 However, the very low prevalence of cerebral palsy (antepartum events are most likely causative agents), hypoxic-ischemic encephalopathy, and fetal death has led to a false-positive rate of 99%3 for continuous electronic fetal monitoring and a low predictive value.810 Additionally, continuous electronic fetal monitoring is falsely positive for fetal acidosis two-thirds of the time, with low sensitivity (57%) and specificity (69%).1,3 Furthermore, user variability in interpretation is high, with agreement between experts only half the time.11,12, Continuous electronic fetal monitoring includes external and internal monitoring.7 External monitoring involves placement of two monitors (one for FHR and the other for contractions) against the maternal abdomen. Multivariate logistic regression analyses were performed to control for confounding variables (SPSS). Which nursing intervention is necessary before a second trimester transabdominal ultrasound? Patient information: See related handout on electronic fetal monitoring, written by the author of this article. Clinically, loss of beat-to-beat variability is more significant than loss of long-term variability and may be ominous.18 Decreased or absent variability should generally be confirmed by fetal scalp electrode monitoring when possible. The inhibitory influence on the heart rate is conveyed by the vagus nerve, whereas excitatory influence is conveyed by the sympathetic nervous system.
