研究目的: |
探讨在资源有限条件下(无法获取专业LISA管,采用6号胃管/吸痰管代替LISA专用导管),采用INSURE技术对比LISA注入PS,能减少SpO2下降,减少机械通气发生,进而减少BPD发生。我们拟开展随机对照研究验证假设,探索在资源有限条件下的超早产儿群体中更优化的肺表面活性物质应用策略。 |
||||||||||||||||||||||
|
Objectives of Study: |
To investigate whether, under resource-limited conditions (where specialized LISA catheters are unavailable and replaced by No. 6 gastric tubes/suction catheters), the INSURE technique compared to LISA for surfactant administration can reduce episodes of SpO? desaturation, decrease the need for mechanical ventilation, and subsequently lower the incidence of bronchopulmonary dysplasia (BPD). We plan to conduct a randomized controlled study to test this hypothesis and explore more optimized surfactant application strategies for extremely preterm infants in resource-constrained settings. |

随机方法(请说明由何人用什么方法产生随机序列): |
随机化操作由独立团队(统计组)管理。权限分级管理,其中中心管理员可查看本中心数据,管理用户权限。研究者仅能录入患者信息并触发随机化。监查员仅查看数据,无修改权限。抽查分层变量录入准确性(随机选择10%病例核对原始病历)。技术支持团队设立24小时热线,处理系统故障或操作疑问。紧急情况下启用备用随机化方案(电话随机化)。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Randomization was managed by an independent team (the statistics group). Access rights were hierarchically controlled: the central administrator could view data from their center and manage user permissions. Investigators were only permitted to enter patient information and initiate randomization. Monitors could only view data without modification rights. To ensure accuracy, stratified variable entries were spot-checked (10% of cases were randomly selected for verification against original medical records). A technical support team established a 24-hour hotline to handle system failures or operational inquiries. A backup randomization procedure (telephone randomization) was activated in emergency situations. |
