研究目的:

探讨如何提高慢性阻塞性肺疾病急性加重期(AECOPD)合并急性呼吸衰竭患者机械通气的脱机成功率。本研究拟通过前瞻性随机对照试验,系统评价早期实施低水平压力支持通气联合带管高流量给氧对脱机拔管成功率、再插管率、机械通气及ICU住院时长等结局的影响,并与常规脱机流程比较。项目将构建以呼吸肌功能、气体交换效率、血流动力学为核心的多维度评估体系,动态监测并指导个体化脱机决策。旨在明确该创新联合策略的优越性,优化脱机流程,降低并发症和死亡率,为AECOPD患者提供可推广的标准化脱机管理新方案,推动精准医学在重症呼吸管理领域的应用与发展。  

Objectives of Study:

Enhancing Liberation from Mechanical Ventilation in Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) Complicated by Acute Respiratory Failure: A Prospective Randomized Controlled Trial. This study aims to conduct a prospective randomized controlled trial to systematically evaluate the impact of early implementation of low-level pressure support ventilation combined with high-flow nasal oxygen therapy with an endotracheal tube on outcomes such as extubation success rate, reintubation rate, duration of mechanical ventilation, and length of ICU stay, compared with conventional weaning protocols. The project will establish a multidimensional assessment system centered on respiratory muscle function, gas exchange efficiency, and hemodynamics, enabling dynamic monitoring and guiding individualized weaning decisions. It seeks to clarify the superiority of this innovative combined strategy, optimize the weaning process, reduce complications and mortality, provide a scalable new standard for weaning management in AECOPD patients, and promote the application and development of precision medicine in the field of critical respiratory care.

指标中文名:

自主呼吸实验(SBT)

指标类型:

次要指标

Outcome:

Spontaneous Breathing Trial (SBT)

Type:

Secondary indicator

测量时间点:

呼吸力学相关的撤机参数符合通过标准后,在准脱机前1-2天进行

测量方法:

标准SBT实验,包括:呼吸频率(次/分)、血氧饱和点(SpO2)、心律、心率(次/分)、氧合指数(PaO2/FiO2)、PaCO2变化(较基线提高)、临床症状、气道通畅性等进行评估,此实验用于直观评价患者脱机后的耐受能力。

Measure time point of outcome:

When respiratory mechanics-related weaning parameters meet the passing criteria, proceed 1–2 days pr

Measure method:

A standard Spontaneous Breathing Trial (SBT) includes the assessment of the following parameters: respiratory rate (breaths/min), oxygen saturation (SpO?), heart rhythm, heart rate (beats/min), oxygenation index (PaO?/FiO?), change in PaCO? (increase from baseline), clinical symptoms, and airway patency. This trial is used to directly evaluate the patient's tolerance after weaning.

Measure time point of outcome:

After removal of the endotracheal tube until day 28

Measure method:

For inpatients, assessment will be conducted based on their specific conditions during the treatment process. For discharged or transferred patients, telephone follow-up will be performed. Cases involving death or other special circumstances will be analyzed individually as special cases.

指标类型:

次要指标

Outcome:

Weaning Parameters Related to Respiratory Mechanics

Type:

Secondary indicator

测量时间点:

尽量在插管后7天内,不超过10天

测量方法:

通过呼吸机进行呼吸力学相关撤机参数的测定,如:P0.1(口腔闭合压)、POCC(自主吸气努力)、MIP(最大吸气压)、PEF(呼气峰流速)。此参数用于评估患者自主呼吸驱动力,以评价脱机成功率。

Measure time point of outcome:

Preferably within 7 days after intubation, and not exceeding 10 days.

Measure method:

Respiratory mechanics-related weaning parameters, such as P0.1 (airway occlusion pressure), POCC (patient's own cough capability, or spontaneous inspiratory effort), MIP (maximal inspiratory pressure), and PEF (peak expiratory flow), are measured using a ventilator. These parameters are used to assess the patient's spontaneous breathing drive and evaluate the likelihood of successful weaning.
