Cardiotocography (CTG) parameters show varying predictive value for perinatal outcomes. Antepartum, fetal heart rate (FHR) baseline and variability are key, while intrapartum, decelerations and uterine contractions become more significant.

Area of Science:

  • Obstetrics and Gynecology
  • Fetal Monitoring
  • Perinatal Medicine

Context:

  • Computerized cardiotocography (CTG) is a standard tool for assessing fetal well-being.
  • Understanding the relationship between CTG parameters and perinatal outcomes is crucial for clinical decision-making.
  • This study analyzed 308 CTG examinations in 190 third-trimester pregnancies.

Purpose:

  • To investigate the association between various computerized cardiotocography (CTG) parameters and perinatal outcomes.
  • To determine the relative importance of different CTG parameters in antepartum versus intrapartum settings.

Summary:

  • Antepartum: Fetal heart rate (FHR) baseline and variability (e.g., BHR, RMSSD, NN50, AC) showed significant correlations with Apgar scores, amniotic fluid color, and umbilical cord blood gas analysis (ABE, SO2).

  • Intrapartum: FHR decelerations (e.g., AMP, H/T) and uterine contraction parameters (e.g., UTDUR, UTS, UTAMP, HR/HU) demonstrated significant relationships with perinatal outcomes, including Apgar scores, amniotic fluid color, and blood gas indices (PH, ABE, PO2, HCO3, TCO2).
  • During intrapartum, the ratio of amplitude to uterine amplitude (HR/HU) was particularly noted as potentially useful.

    • Impact:

    • Antepartum CTG parameters, particularly FHR baseline and variability, are more predictive of perinatal outcomes.
    • Intrapartum CTG analysis, focusing on decelerations and uterine contractions, provides critical insights into fetal status during labor.
    • The findings can refine the interpretation of CTG tracings, leading to improved management and outcomes for high-risk pregnancies.
