Randomized Controlled Trial of Two Methods of Diagnosing Preterm Labor
Use of modern diagnostic tools e.g. fetal fibronectin and ultrasound measurement of cervical
length to diagnose preterm labor can result in improved outcomes compared to traditional
diagnosis based on digital examination to measure cervical change.
length to diagnose preterm labor can result in improved outcomes compared to traditional
diagnosis based on digital examination to measure cervical change.
Symptomatic preterm labor patients will be randomized to diagnosis of preterm labor by
serial digital examination versus an algorithm incorporating transvaginal ultrasound
measurement of cervical length and vaginal fetal fibronectin.
