目的 探讨多胎妊娠管理模式.方法 将290例多胎妊娠产妇分为A、B、C三组,2010年85例分为对照A组,为传统孕期产检；2011年73例分为实验B组,孕晚期B超测量宫颈长度预测早产,2012年132例为实验C组,孕晚期B超测量宫颈长度联合检测胎儿纤维连接蛋白(fFN)预测早产.对比三组平均孕周和平均出生体重.结果C组孕周(36.1±1.1),较A组(33.8±1.4)、B组(35.6±1.3)延长(P＜0.05)；C组早产率(43.2％)较A组(60.0％)、B组(52.0％)降低(P＜0.05)；C组新生儿平均体重[(2.48±0.04)kg]较A组[(2.24±0.03)kg]、B组[(2.36±0.03)kg]升高(P＜0.01)；C组妊娠并发症较A、B组减少(P＜0.05).结论 加强多胎妊娠管理,可以有效预测早产,及时采取有效措施,减少母婴并发症.%Objective To investigate the management mode of multiple pregnancy.Methods 290 cases of multiple pregnancies were divided into three groups (group A,group B and group C),85 cases were treated with traditional pregnancy inspection in 2010 as group A; 73 cases were treated with traditional pregnancy inspection and measurement of cervical length prediction of preterm delivery through ultrasound during the late pregnancy in 2011 as group B; 132 cases treated with traditional pregnancy inspection,were measured the cervical length prediction of preterm delivery through ultrasound and the level of Fibronectin (fFN) in 2012 as group C.The average gestational weeks and the average birth weight were analyzed among three groups.Results Compared with group A and B,the gestational weeks prolonged (P＜0.05),the preterm birth rate and pregnancy complications declined (P＜0.05),and the average birth weight increased in group C (P＜0.01).Conclusion Strengthening the management of multiple pregnancy can effectively predict preterm delivery and reduce the complications of mothers and infants.
