Summary
Doppler color ultrasonography reliably detects nuchal cord entanglement in pregnant women. This method aids clinicians in identifying cases needing closer fetal surveillance during labor, improving obstetric care.
Area of Science:
- Obstetrics and Gynecology
- Medical Imaging
- Fetal Medicine
Background:
- Nuchal cord entanglement occurs in a significant percentage of pregnancies.
- Accurate detection of nuchal cords is crucial for appropriate management.
- Doppler ultrasonography offers a non-invasive method for fetal assessment.
Purpose of the Study:
- To evaluate the efficacy of Doppler color ultrasonography in detecting nuchal cord entanglement.
- To measure the resistance index in fetuses with and without nuchal cords.
- To assess the correlation between nuchal cord entanglement and delivery outcomes.
Main Methods:
- Prospective, observational, cross-sectional study.
- Inclusion of 132 low-risk term pregnant women.
- Utilized Doppler color ultrasonography to assess umbilical cord encirclement and resistance index.
Main Results:
- Doppler ultrasonography demonstrated high sensitivity (92%) and specificity (87%) for detecting nuchal cord entanglement.
- Nuchal cord entanglement was associated with a higher rate of cesarean sections (70%).
- No significant differences were observed in fetal distress, Apgar scores, or birth weight.
Conclusions:
- Color Doppler ultrasonography is a reliable tool for detecting nuchal cord entanglement.
- Doppler assessment can guide closer fetal monitoring during labor, particularly with cardiotocography.
- This imaging technique aids in clinical decision-making for managing pregnancies with nuchal cords.
