研究目的:

(1)主要研究目的 本研究旨在比较托下颌(jaw thrust)与托下颌联合腹部按压两种干预方式在无痛胃镜检查过程中出现低氧血症(SpO₂ < 95%)时的纠正效果,明确在发生低氧后,腹部按压是否可加速SpO₂恢复、提高治疗效率,从而为无创、快速、低资源条件下的呼吸支持手段提供循证依据。 (2)次要研究目的 1)评估“托下颌+腹部按压”干预对患者最低SpO₂水平的影响; 2)比较两组患者在干预后是否需要中断胃镜检查进行退镜通气的发生率; 3)比较两组患者在低氧发生后的1分钟内SpO₂变化趋势; 4)评估两组间不良事件发生率(如心动过缓、低血压、呕吐等); 5)探讨两种干预方式对总环泊酚使用量及苏醒时间的影响; 6)观察腹部按压干预的可行性和临床操作安全性。  

Objectives of Study:

(1) Primary Research Objective This study aims to compare the corrective effects of two intervention methods—jaw thrust alone and jaw thrust combined with abdominal compression—for hypoxemia (SpO₂ < 95%) occurring during painless gastroscopy. It seeks to clarify whether abdominal compression can accelerate SpO₂ recovery and improve treatment efficiency after hypoxemia onset, thereby providing evidence-based support for non-invasive, rapid, and low-resource respiratory support strategies. (2) Secondary Research Objectives 1) Evaluate the impact of the "jaw thrust + abdominal compression" intervention on the minimum SpO₂ level in patients; 2) Compare the incidence of gastroscopy interruption (for scope withdrawal and ventilation) required after intervention between the two patient groups; 3) Compare the SpO₂ change trends within 1 minute after hypoxemia onset between the two patient groups; 4) Assess the incidence of adverse events (e.g., bradycardia, hypotension, vomiting) between the two groups; 5) Explore the effects of the two intervention methods on the total propofol dosage administered and patient recovery time; 6) Observe the feasibility and clinical operational safety of the abdominal compression intervention.

公开/Public

盲法:

非盲对象: 干预操作者(即执行托下颌/腹部按压的麻醉医师)因需直接实施操作,无法设盲; 盲法对象: 数据分析者:仅接收去标识化后的数据,不知晓具体分组; 受试者:在镇静状态下对干预方式不知情。

Blinding:

Non-Blinded Participants: Intervention operators (i.e., anesthesiologists who perform jaw thrust/abdominal compression) cannot be blinded as they need to directly conduct the intervention. Blinded Participants: Data analysts: Only receive de-identified data and are unaware of the specific grouping of participants; Participants: Unaware of the intervention method due to being in a sedated state.
