Area of Science:

  • Obstetrics and Gynecology
  • Medical Informatics
  • Fetal Monitoring

Context:

  • Cardiotocography (CTG) is crucial for fetal well-being assessment.
  • Existing CTG analysis methods have limitations in accuracy, especially for decelerations.
  • Computer-aided analysis offers potential for objective and precise interpretation.

Purpose:

  • To develop and evaluate an original hardware and software system for analyzing fetal cardiotocograms (CTG).
  • To refine computer interpretation of CTG parameters, including baseline heart rate, variability, accelerations, and decelerations.
  • To address the issue of high false negativity in the interpretation of decelerations.

Summary:

  • A PC XT IBM compatible system with intelligent analog input periphery and modified Maeda's CTG evaluation scheme was used.

  • 25 fetal tracings (over 8.5 hours) were analyzed, detailing pathogenomic phenomena and their correlations.
  • Statistical evaluation focused on decelerations, highlighting improvements in reducing false negativity.

    • Impact:

    • The developed system offers a more accurate computer interpretation of fetal CTG data.
    • Improvements in deceleration analysis can lead to better clinical decision-making in obstetrics.
    • Proposed enhancements include scheme optimization, real-time graphic presentation, and improved documentation outputs.
