Main purpose: To investigate the delivery rate of two cervix cerclings in pregnant women with cervical dysfunction at less than 34 weeks.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 年龄18岁至40岁;
2. 符合宫颈功能不全诊断标准的孕期妇女:
3. 基于病史进行诊断 目前认为即使是 1 次或 2次的早孕晚期无痛性宫颈扩张、继之孕中期无宫缩、产兆和出血、感染、破膜等明确的病理因素,妊娠物排出的典型病史,即可进行诊断;
4. 基于孕中期宫颈长度和宫颈缩短等超声标志进行诊断 宫颈长度的临界值为 25 mm,宫颈长度小于25mm认为宫颈功能不全;
5. 非孕期的试验性诊断 包括子宫输卵管造影术(HSG),黄体期用7号宫颈扩张器评估宫颈扩张情况方法。
6. 接受了经阴道宫颈环扎术妊娠妇女;
7. 有意愿参加本研究。

Inclusion criteria

1. Aged 18 to 40 years;
2. Pregnant women who meet the diagnostic criteria for cervical insufficiency:
3. Diagnosis based on medical history It is currently believed that even if it is 1 or 2 times of painless cervical dilation in the third trimester of pregnancy, followed by no uterine contractions in the second trimester, labor signs and bleeding, infection, membrane rupture and other clear pathological factors, pregnancy products are discharged. The typical medical history can be diagnosed;
4. Diagnosis based on ultrasound markers such as cervical length and cervical shortening in the second trimester. The critical value of cervical length is 25 mm, and cervical insufficiency is considered when the cervical length is less than 25 mm;
5. Trial diagnosis in non-pregnant period Including hysterosalpingography (HSG), luteal phase with cervical dilator 7 to assess cervical dilation method.
6. Pregnant women who have undergone transvaginal cervical cerclage;
7. Willingness to participate in this research.

排除标准:

1.胎儿异常;
2.临床上显著的母胎并发症(如胎儿红细胞同种免疫、慢性高血压、胰岛素依赖型糖尿病,前置胎盘、胎盘早剥);
3.超声及宫腔镜检查发现子宫结构异常(如子宫畸形、子宫肌瘤等);
4.不明原因的阴道出血;
5.合并有以下疾病且症状尚未控制:哮喘、II型糖尿病、严重的感染;
6.既往有宫颈环扎史;
7.妊娠35周之前因先兆子痫,宫内胎儿死亡和/或胎儿状况不确定而自愿终止妊娠或医学指示分娩的患者;
8.拒绝参加本研究者。

Exclusion criteria:

1. Fetal abnormalities;
2. Clinically significant maternal-fetal complications (such as fetal red blood cell alloimmunity, chronic hypertension, insulin-dependent diabetes mellitus, placenta previa, placental abruption);
3. Ultrasound and hysteroscopy found abnormal uterine structure (such as uterine malformation, uterine fibroids, etc.);
4. Unexplained vaginal bleeding;
5. Combined with the following diseases and the symptoms have not been controlled: asthma, type II diabetes, serious infection;
6. History of cervical cerclage in the past;
7. Patients with voluntary termination of pregnancy or medically directed delivery due to preeclampsia, intrauterine fetal death and/or uncertain fetal status before 35 weeks of gestation;
8. Refuse to participate in this researcher.

盲法:

在整个试验过程中,受试者、受试者的照护者、统计人员均不知道受试者接受的治疗方案。所有参与研究的人员均签署保密承诺书,避免泄盲。在CRF中仅体现受试者的随机号,不体现受试者的组别。

Blinding:

During the entire trial, the subjects, their caregivers, and statisticians were unaware of the treatment regimens the subjects were receiving. All participants in the study signed a confidentiality commitment to avoid blindness. In CRF, only the random number of the subject is reflected, and the group of the subject is not reflected.
