Triage by cervical length sonographic measurements for targeted therapy in threatened preterm labor: A double blind randomized clinical trial

Preterm labor and birth are associated with several neonatal complications including respiratory distress syndrome and intraventricular hemorrhage. Differentiating true and false labor pain is a dilemma to obstetricians.

To elucidate the role of cervical length measurement in prediction of birth in pregnant women with threatened preterm labor.

In this double blind randomized clinical trial, 120 women with gestational age

This RCT showed in case group, 78.9% of patient with cervical length

“Our results indicate that in women who presented preterm labor symptoms, cervical length measurement will result in decreased unnecessary tocolytic treatment. Women with cervical length ≥15mm should not receive tocolysis, however, withholding corticosteroid therapy in these patients needs further evidence.
