Cervical Volume by Three-Dimensional Ultrasound as a Predictor of Preterm Delivery

NCT00342550 · View on ClinicalTrials.gov ↗

Study Summary

Preterm labor is a leading cause of perinatal morbidity and mortality. Several investigators have reported that ultrasound evaluation of the cervix can predict the risk of preterm delivery. Three-dimensional ultrasound may provide additional information about how to best counsel parents about the chances of premature birth. This technology has the capability for accurate volume measurements of irregular structures that is superior to conventional ultrasound. Therefore, it is possible that three-dimensional ultrasound methods may better characterize cervical changes and the risk for preterm delivery. Our protocol will attempt to identify prognostic indicators of adverse pregnancy outcome by three-dimensional ultrasound. A maximum of 680 pregnant women with the diagnosis of preterm labor will be prospectively studied to characterize cervical morphology and volume as predictors of preterm delivery risk. These results will be correlated with placental pathology and pregnancy outcome. We will also compare the performance of conventional two-dimensional endovaginal ultrasound with three-dimensional ultrasound findings. This information is expected to improve our understanding about the nature and timing of cervical volume changes in relation to pregnancy outcome.

What the Registry Record Tells You About NCT00342550

The ClinicalTrials.gov registry entry for NCT00342550 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 648 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), which has 237 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.

The record links to 3 conditions, with Pregnancy appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.

Geographic footprint matters for practical reasons: NCT00342550 reports 1 study location spanning 1 distinct geographic area — top geographies include Michigan. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
