研究目的:

评估呼吸肌激活技术在ICU机械通气患者中应用的可行性与安全性;初步观察该技术对呼吸肌功能(膈肌厚度、增厚分数)、腹压波动、肠蠕动的影响;为后续大样本随机对照试验提供方法学依据和样本量估算基础。  

Objectives of Study:

To evaluate the feasibility and safety of the respiratory muscle activation technique in mechanically ventilated ICU patients; to preliminarily observe its effects on respiratory muscle function (diaphragm thickness, thickening fraction), intra-abdominal pressure fluctuation, and bowel motility; and to provide methodological basis and sample size estimation for a future large-scale randomized controlled trial.

药物成份或治疗方案详述:

本研究不涉及药物。治疗方案为“呼吸肌激活技术”,一种被动康复训练。具体操作: 操作前准备: 患者取半卧位(床头抬高30°),暂停肠内营养输注30分钟,监测基线生命体征。 操作流程(每日1次,每次20分钟): 腹压波动诱发(屈膝屈髋动作): 操作者站于患者一侧,一手托膝关节,另一手托踝关节,缓慢屈膝至90°,同时屈髋使膝关节向腹部靠近,当膝关节接近腹部时缓慢向对侧旋转骨盆,保持最大活动范围3-5秒,缓慢恢复原位。每侧肢体重复15-20个周期(约5分钟/侧)。 肋间隙开合(肩关节伸展动作): 操作者一手固定患者肩胛骨,另一手握住腕关节,缓慢将上肢向外侧上方伸展至最大范围,保持3-5秒,缓慢恢复原位。每侧肢体重复15-20个周期(约5分钟/侧)。 操作注意事项: 动作缓慢平稳,密切监测生命体征。若出现心率或收缩压变化>基础值20%、SpO?<90%或患者明显不适,立即停止操作。 干预周期: 4周,每周5天(周一至周五),每日1次(上午)。 

Description for medicine or protocol of treatment in detail:

This study involves no drugs. The treatment is a passive rehabilitation technique named "Respiratory Muscle Activation Technique". Details are as follows: Pre-procedure: Place patient in semi-recumbent position (head of bed elevated 30°), stop enteral nutrition for 30 minutes, and monitor baseline vital signs. Procedure (once daily, 20 minutes each): Induction of intra-abdominal pressure fluctuation (knee flexion + hip flexion): The operator stands on one side of the patient, holds the knee and ankle, slowly flexes the knee to 90° while bringing the knee toward the abdomen, then slowly rotates the pelvis to the opposite side when the knee is near the abdomen. Maintain the maximum range for 3-5 seconds, then slowly return. Repeat 15-20 cycles per side (approximately 5 minutes per side). Intercostal space opening (shoulder extension): The operator fixes the scapula with one hand and holds the wrist with the other, slowly extends the upper limb outward and upward to the maximum range, holds for 3-5 seconds, then slowly returns. Repeat 15-20 cycles per side (approximately 5 minutes per side). Precautions: Perform movements slowly and smoothly, closely monitor vital signs. Stop immediately if heart rate or systolic blood pressure changes >20% from baseline, SpO? <90%, or obvious patient discomfort occurs. Intervention period: 4 weeks, 5 days per week (Monday to Friday), once daily (morning).
