A clinical test for diagnosing nuchal cords.
A simple, noninvasive clinical test for detecting nuchal cords late in pregnancy and during labor is based on recording the changes in the fetal heart rate produced by transabdominal manual compression of the fetal neck area. The test was applied in 88 women close to full term and to 67 women in labor. Overall, the sensitivity of the test was 82.3% and specificity, 89.1%. The results were statistically significant in both late pregnancy and labor. A positive test implies an impending risk of cord compression and is an indication for close electronic fetal monitoring, particularly during labor. Routine use of the nuchal cord test can contribute to decreasing perinatal morbidity and mortality by diminishing the impact of cord problems.
