Cerclage for Singletons With Short Cervix Without Prior Preterm Birth
Study Details
Study Description
Brief Summary
Preterm birth remains the most common cause of perinatal morbidity and mortality. A short cervi- cal length on transvaginal ultrasonography has been shown to be one of the best predictors of preterm birth. In 2005 a meta-analysis by Berghella et al. showed that cervical cerclage does not prevent preterm birth (PTB) in women with short cervical lenght without prior PTB. However maybe the meta-analysis did not reach the statistical significance due to the small sample size

Experimental: Cervical cerclage Women randomized to receive cerclage should receive cervical cerclage Cerclage is a circumferential stitch of non-absorbable suture placed around the cervix |
Procedure: Cervical cerclage
Cerclage is a circumferential stitch of non-absorbable suture placed around the cervix Cerclage type: McDonald Cerclage Suture: Permanent monofilament Pericerclage antibiotics: none Pericerclage tocolytics: none Bed rest: not recommended (in both groups)
