Does Fetal Fibronectin and Ultrasound Cervical Length Help in the Evaluation of Women With Suspected Preterm Labor?
The objective of this study is to investigate the effect of the use of both sonographic cervical length (CL) and fetal fibronectin (FFN) on the length of outpatient triage and preterm labor interventions in symptomatic women with intact membranes.
We performed a randomized trial of the use of transvaginal ultrasound cervical length and fetal fibronectin in women being evaluated for suspected PTL at a gestational age between 24 and 33 weeks 6 days. Women are randomized to either a standard (blinded) or a protocol arm. Women in the standard arm are evaluated without the results of the CL and FFN while women in the protocol arm are evaluated using the results of the CL and FFN and managing physicians are asked to follow a specific PTL algorithm to determine a women’s eligibility for treatment. The primary outcome is length of stay in the triage area before discharge.
