Abnormal Intrapartum Cardiotocographic Tracing, Fetal Outcome and Placental Pathology

Area of Science:

• Obstetrics and Gynecology
• Perinatal Medicine
• Fetal Surveillance

Background:

• Cardiotocography (CTG) is crucial for intrapartum fetal surveillance but suffers from interpretation complexity and interobserver variability.
• Placental pathology is increasingly recognized as a significant factor in adverse perinatal events.
• This study investigates the link between abnormal CTG patterns and placental abnormalities.

Purpose of the Study:

• To examine the relationship between pathological intrapartum cardiotocography (CTG) tracings and maternal-fetal outcomes.
• To correlate CTG findings with macroscopic and microscopic placental abnormalities.
• To compare these findings with a control group of uncomplicated pregnancies.

Main Methods:

• Retrospective analysis of 85 patients with pathological intrapartum CTG tracings.
• Inclusion of maternal, fetal, and placental histopathological data.
• Comparison with a control group of 50 women with normal CTG patterns.

Main Results:

• Pathological CTG cases showed poorer neonatal outcomes, including lower Apgar scores and higher NICU admissions.
• Significantly higher incidence of placental abnormalities like hypercoiled umbilical cords and intervillous thrombosis in the pathological CTG group.
• Elevated birth weight-to-placental weight ratio in the pathological CTG group indicated potential uteroplacental insufficiency.

Conclusions:

• Pathological CTG reflects multifactorial dysfunction of the feto-placental unit, not an isolated event.
• Associations with adverse outcomes and placental findings support the interplay of chronic placental issues and acute factors in fetal hypoxia.
• Future predictive models integrating diverse variables could enhance early risk identification and intrapartum management.
