摘　　要：随着辅助生殖技术的发展,双胎妊娠孕产妇数量逐年上升。作为早产高风险人群,目前尚缺乏预防双胎妊娠早产的有效方法。宫颈托是近年新兴的一种预防早产的方法,其作用机制主要是对宫颈内口起物理性承托作用,减轻宫颈内口压力,可预防双胎妊娠早产,延长孕周,缩短住院时间,改善新生儿预后。与其他预防早产的方法相比,宫颈托为无创操作,具有无须麻醉、操作简便、不良反应少等优点。目前,临床仍缺乏高质量大规模的随机对照试验,故未来需进一步研究以证实其疗效。With the development of assisted reproductive technology,the number of twin pregnancy and parturient women in double pregnancy is increasing year by year.As a high risk group for preterm labor,there is still a lack of effective methods to prevent preterm labor in twin pregnancy.Pessary is a new method to prevent premature birth in recent years.Its main mechanism is physical supporting effect on cervical intraoral,reducing the pressure of cervical intraoral pressure.preventing premature delivery of twin pregnancy,prolonging gestational age,shortening hospitalization time and improving the prognosis of newborns.Compared with other methods of preventing preterm birth,pessary is a noninvasive operation with the advantages of no anesthesia,easy operation,and less adverse reaction.At present,there is still a lack of high quality large scale randomized controlled trials,so further study is needed to prove its efficacy in the future.
