宫颈环扎术治疗宫颈机能不全的研究进展

Research progress of cervical cerclage in the treatment of cervical incompetence

宫颈机能不全(CIC)常表现为反复发生妊娠中晚期无痛性宫颈管缩短、扩张,最终导致难免流产或早产。早产儿的出生严重影响人口质量和健康素质,在妊娠22~26周期间每延迟分娩1 d,新生儿可增加3%的存活率。宫颈环扎术可有效延长妊娠周数、降低流产与早产的发生率。因此选择合适的手术时机、进行规范的术后管理对提高宫颈环扎术的成功率、延长妊娠周数至关重要。本文结合国内外相关临床研究与最新指南,综述宫颈环扎术的手术时机、术后药物管理及术后随访等。

Cervical incompetence(CIC)is often characterized by repeated painless shortening and dilation of the cervical canal in the middle and late trimester of pregnancy,resulting in inevitable abortion or preterm labor.The birth of premature infants seriously affects the quality and health of the population.Every day of delayed delivery at 22 to 26 weeks of gestation increases the survival rate of newborns by 3%.Cervical cerclage can effectively prolong pregnancy weeks and reduce the incidence of miscarriage and premature delivery.Therefore,it is very important to choose the right operation time and carry out standard postoperative management to improve the success rate of cervical cerclage and prolong pregnancy weeks.Based on domestic and foreign clinical studies and the latest guidelines,this paper reviews the timing of cervical cerclage,postoperative drug management and postoperative follow-up.
