研究目的:

本研究旨在评估护士主导的床旁即时超声(POCUS)引导靶向胸部物理治疗(CPT)在新生儿重症肺炎中的有效性、安全性及临床可行性。主要目的为评价该干预是否能够缩短患儿有创机械通气时间,并改善氧合/血气指标、肺力学指标及肺部影像学变化;次要目的为比较两组无呼吸机天数、拔管失败率、住院时间、全因死亡率及不良事件发生率;同时建立护士主导肺部POCUS的培训与质量控制体系,评估护士对标准化超声征象及病变区域定位的一致性,推动POCUS在NICU护理中的规范化应用。  

Objectives of Study:

This study aims to evaluate the effectiveness, safety, and clinical feasibility of nurse-led point-of-care ultrasound (POCUS)-guided targeted chest physiotherapy (CPT) in neonates with severe pneumonia. The primary objective is to determine whether this intervention can reduce the duration of invasive mechanical ventilation and improve oxygenation/blood gas parameters, pulmonary mechanics, and imaging outcomes. The secondary objectives are to compare ventilator-free days, extubation failure rate, length of hospital stay, all-cause mortality, and adverse events between groups. In addition, this study aims to establish a nurse-led lung POCUS training and quality-control system, assess the consistency of nurses in identifying standardized ultrasound signs and lesion localization, and promote the standardized integration of POCUS into NICU nursing practice.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用阶梯式楔形整群随机设计,以NICU为随机单位。3家参与中心在第1阶段均接受标准护理;随后由独立统计学人员使用计算机生成随机数字序列,确定各NICU在第2、3、4阶段开始时依次由对照期转换至干预期的顺序。随机序列生成后由中心协调组统一保存,并据此实施分阶段转换。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study uses a stepped-wedge cluster randomized design, with the NICU as the unit of randomization. All three participating NICUs start in the control condition during Period 1. An independent statistician will generate the random sequence using a computer-based random number method to determine the order in which each NICU crosses over from control to intervention at the start of Periods 2, 3, and 4. The randomization schedule will be centrally maintained by the coordinating team and implemented according to the prespecified transition sequence.

盲法:

本研究采用部分盲法。由于干预措施为护士实施床旁即时超声(POCUS)评估及靶向胸部物理治疗,临床实施人员无法设盲,患儿监护人亦难以完全设盲。受试者为新生儿,不涉及主动知晓分组。为降低偏倚,结局数据提取、资料复核及统计分析由不参与干预实施且尽可能不知晓分组信息的研究人员完成。

Blinding:

This study uses partial blinding. Owing to the nature of the intervention, which involves nurse-performed point-of-care ultrasound (POCUS) assessment and targeted chest physiotherapy, blinding of the clinical staff delivering the intervention is not feasible, and complete blinding of parents or guardians is also difficult. As the participants are neonates, active awareness of group assignment does not apply. To reduce bias, outcome data extraction, data review, and statistical analysis will be performed by research personnel who are not involved in the intervention and are kept unaware of group allocation whenever possible.

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:

本研究采用标准化病例报告表(CRF)和电子数据库相结合的数据采集与管理模式。各分中心研究人员使用统一CRF收集受试者基线资料、机械通气信息、血气和呼吸机参数、肺部超声评估结果、胸部物理治疗执行情况、不良事件及结局指标。研究数据主要来源于EMR电子病历系统、床旁监护/呼吸机记录以及研究期间护士实施POCUS所得参数。所有肺部超声关键切面图像及干预记录均上传至研究影像库,由分中心指定医师在规定时限内复核。主中心设数据管理员负责数据库维护、数据核查、缺失值与逻辑错误核对;每月抽取各中心部分图像和数据进行质控,必要时开展再培训或稽核。所有受试者均以唯一研究编号标识,个人可识别信息与研究数据库分开保存,电子数据采用密码保护和分级授权访问,纸质资料存放于科室专用档案柜。数据收集和统计分析在可行情况下实行部分盲法,以降低偏倚。

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

A standardized case report form (CRF) together with an electronic database will be used for data collection and management. Investigators at each site will use uniform CRFs to collect baseline characteristics, mechanical ventilation data, blood gas and ventilator parameters, lung ultrasound findings, chest physiotherapy intervention records, adverse events, and study outcomes. Study data will be obtained primarily from the electronic medical record (EMR) system, bedside monitor/ventilator documentation, and POCUS measurements performed by trained nurses during the study. Key lung ultrasound images and intervention records will be uploaded to a study imaging repository and reviewed by designated physicians at each site within the prespecified timeframe. A central data manager will oversee database maintenance, data verification, and queries for missing or inconsistent data. Periodic quality control will be conducted through review of sampled images and data across centers, with retraining or audit when necessary. Each participant will be assigned a unique study ID; identifiable personal information will be stored separately from the research database. Electronic data will be password-protected with role-based access control, and paper records will be stored in a secure departmental archive. Partial blinding will be applied to data collection and statistical analysis whenever feasible to minimize bias.
