研究目的:

传统的双胞胎剖宫产手术方法(TSM)主要是在第一个胎儿娩出后直接剪断脐带。为了减少双胞胎剖宫产手术中的产后出血,我们引进了一种新的手术技术。该技术的具体细节如下:第一个胎儿娩出后,脐带最初留在原位,即 DCC,并置于产妇的上腹部,同时助手稳定胎儿。第一个胎儿娩出后,及时采取保暖措施至关重要。然后迅速娩出第二个胎儿,接着夹紧子宫切口并剪断脐带,完成剖宫产手术。我们中心将这项技术命名为 “改良剖宫产手术法(ISM)”。为了评估ISM方法在双胎妊娠中的安全性和有效性,本研究比较并分析了ISM组和TSM组在产后出血、术中指标、孕产妇和新生儿预后等几个关键方面的优势。  

Objectives of Study:

The traditional cesarean section surgery method (TSM) for twins mainly involves cutting the umbilical cord directly after the first fetus is delivered. To reduce postpartum hemorrhage in cesarean section surgery for twins, we are introducing a novel surgery technique. The details of the technique are as follows, after the first fetus is delivered, the umbilical cord is initially left in place meaning DCC, and positioned on the mother's upper abdomen while the assistant stabilizes the fetus. It is crucial to promptly take steps to keep the first fetus warm after delivery. The second fetus is then delivered swiftly, followed by clamping the uterine incision and cutting the umbilical cord to complete the cesarean section. We have named this technique the ‘Improved Cesarean Section Surgery Method (ISM)’ at our center. To assess the safety and effectiveness of the ISM method for twin pregnancies, the study compared and analyzed advantages between the ISM group and the TSM group across several key areas, including postpartum hemorrhage, intraoperative indicators, and maternal and neonatal outcomes.

为了管理研究数据,监控研究过程,提高研究的透明度,我们将采用临床试验电子病例记录表(eCRF系统),用于记录和存放患者的数据和结果。数据库管理员和项目负责人将负责在eCRF系统中建立项目空间并管理数据库,分配对用户的管辖权。数据库管理员拥有管理和监视的数据和操作的最高权限。数据库管理人员决定其中的哪些数据可以向公众披露。患者的私人信息包括姓名、年龄、电话号码,将受到严格保护,永远不被泄露。eCRF系统服务提供商将承担负责保证数据库和研究数据的安全,维护数据库的保存工作并提供对数据库的技术支持,但不能更改研究数据中的任何内容。eCRF系统的联系人是为项目负责人。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

In order to manage the study data, monitor the study process, and improve the transparency of the study, we will adopt an electronic clinical trial case record form (eCRF system) for recording and storing patient data and results. The Database Administrator and Project Leader will be responsible for creating the project space in the eCRF system and managing the database, assigning jurisdiction over users. The database administrator has the highest authority over the data and operations that are managed and monitored. The database administrator decides which of these data can be disclosed to the public. Private patient information, including name, age, and telephone number, will be strictly protected and will never be disclosed. eCRF system service providers will assume responsibility for securing databases and study data, maintaining database retention, and providing technical support for the databases, but will not be able to change anything in the study data. eCRF system contact will be the project leader.
