研究目的: |
本研究旨在通过随机对照试验,比较肝素与低分子肝素在预防先天性心脏病术后新生儿中心静脉导管相关血栓(CRT)中的有效性及安全性。重点评估两种药物对血栓发生率的影响差异,监测出血、过敏等不良反应及肝肾功能指标变化,同时探讨用药剂量与时间的优化方案,并通过6个月随访观察对患儿生长发育及心血管功能的远期影响,为新生儿围术期抗凝策略提供循证依据。 |

|
Objectives of Study: |
This study aims to compare the effectiveness and safety of heparin and low molecular weight heparin in preventing central venous catheter-related thrombosis (CRT) in neonates after congenital heart disease surgery through a randomized controlled trial. The focus is on evaluating the difference in the impact of the two drugs on the incidence of thrombosis, monitoring adverse reactions such as bleeding and allergies, and changes in liver and kidney function indicators, while exploring the optimization of medication dosage and time, and observing the long-term effects on the growth and development and cardiovascular function of children through a 6-month follow-up, to provide evidence-based basis for neonatal perioperative anticoagulation strategies. |

随机方法(请说明由何人用什么方法产生随机序列): |
随机序列生成: 采用计算机生成的随机数字(SAS 9.4 PROC PLAN模块),由独立统计师完成,实施分层区组随机化。 分层因素:先天性心脏病类型(发绀型/非发绀型)、手术方式(体外循环/非体外循环)、导管类型(单腔/双腔)。 区组长度:4-6例,按1:1比例分配至肝素组或低分子肝素组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Random sequence generation: Computer-generated random numbers (SAS 9.4 PROC PLAN module) were used by an independent statistician to implement stratified block randomization. Stratification factors: congenital heart disease type (cyanotic/non-cyanotic), surgical method (extracorporeal circulation/non-extracorporeal circulation), catheter type (single-lumen/double-lumen). Block length: 4-6 cases, allocated to the heparin group or low-molecular-weight heparin group in a 1:1 ratio. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
1.病例记录表(CRF) 设计:采用标准化纸质/电子CRF,记录基线信息(人口学、疾病类型、手术方式)、干预数据(药物剂量、APTT/抗Xa活性)、结局指标(血栓、出血事件)及随访结果(生长发育、心血管功能)。 质量控制:双人独立录入,逻辑校验(如数值范围、必填项)。 2.电子数据采集系统(EDC) 系统名称:ResMan临床研究管理系统(基于互联网的EDC) 网址:www.resman.org.cn 功能: 在线实时录入数据,支持多中心协作; 自动校验数据完整性(如缺失值提醒); 权限分级管理(研究者、统计师、监察员分权访问)。 3.数据安全 患儿信息去标识化存储,SSL加密传输; 每日自动备份至医院私有云。 |
|
