Effect of Cervical Pessary on Spontaneous Preterm Birth in Women With Singleton Pregnancies and Short Cervical Length: A Randomized Clinical Trial EDITORIAL COMMENT

摘要

Spontaneous preterm birth is a major cause of maternal and neonatal morbidity; it is estimated that preterm birth caused 1.1 million infant deaths in 2015, as well as short-and long-term disability in survivors. Cervical pessary is a silicone device used to prevent pretermbirth, although its efficacy is unclear as there have been contradictory results in randomized controlled trials (RCTs) in women with singleton pregnancies and short cervical length.
