Identification of nuchal cords during nonstress testing

Area of Science:

• Obstetrics and Gynecology
• Fetal Monitoring
• Perinatal Medicine

Background:

• Nonstress tests (NSTs) are vital for assessing fetal well-being.
• Umbilical cord accidents remain a cause of fetal loss.
• A novel "W pattern" observed on NSTs may indicate fetal nuchal cords.

Purpose of the Study:

• To prospectively evaluate the accuracy of the "W pattern" on NSTs in predicting nuchal cords.
• To assess the association between the "W pattern" and adverse neonatal outcomes.

Main Methods:

• Prospective study of 200 consecutive patients undergoing antepartum fetal heart rate testing.
• Monitoring for the occurrence of a "W pattern" on nonstress tests.
• Correlation of "W pattern" findings with the presence of nuchal cords at delivery.

Main Results:

• One hundred percent of fetuses exhibiting the "W pattern" on NSTs had nuchal cords at birth.
• The "W pattern" was associated with a higher incidence of five-minute Apgar scores below 7.
• The study demonstrated high predictive accuracy for nuchal cords.

Conclusions:

• The "W pattern" on NSTs is a reliable indicator of fetal nuchal cords.
• Identifying nuchal cords prenatally can help manage pregnancies at risk of fetal distress or death.
• This finding may improve perinatal care and reduce adverse fetal outcomes.
