Effect of Early Extracorporeal Diaphragm Pacing Combined With Tilt Table in Ventilated Patients.
Early Mobilization, Critically Ill, Mechanical Ventilation
About this trial
This is an interventional treatment trial for Early Mobilization
Eligibility Criteria
Inclusion Criteria: Duration of mechanical ventilation prior to enrollment≤ 72 hours. Expected duration of mechanical ventilation≥72 hours. Participants (or their legal representatives) have signed informed consent. Exclusion Criteria: Pregnancy or breast-feeding. Prone ventilation or current extracorporeal membrane oxygenation. Hemodynamic instability: mean arterial pressure is less than 65 millimeters of mercury (mmHg) or higher than 85 millimeters of mercury (mmHg), heart rate > 150 beats / minute, intravenous use of larger doses of vasopressors (such as dopamine > 10 mg/ (kg· min) or norepinephrine/epinephrine >0.1 mg/ (kg· min)) or aortic balloon counter pulsation; respiratory rate< 5 breaths per minute; Oxygen saturation< 88%. New-onset myocardial ischemia. Unstable cervical spine fracture and spinal cord injury. Deterioration of neurological function, requiring intracranial pressure monitoring and ventricular drainage, or active control of intracranial hypertension. Current neuromuscular block treatment or pre-existing neuromuscular disease or neuromuscular junction disease affecting respiratory muscle (such as myasthenia gravis, Guillain-Barré syndrome, etc.). There are contraindications to diaphragmatic pacing (local skin, tissue incompleteness or infection, chest X-ray examination shows pneumothorax or pleural effusion accounting for 1/3 of bilateral chest cavity). Body mass index (BMI) ⩾40 kg/m2. Known / suspected phrenic nerve palsy. Patients who refuse active treatment or are in the terminal stage of malignant tumors, have an expected life expectancy of < 6 months, etc. Participated in other clinical studies related to mechanical ventilation within 2 months prior to the start of the study.

In the control condition, patients received conventional physiotherapy (CPT) according to standard clinic procedures.
the experimental group uses Extracorporeal Diaphragm Pacing (EDP) on the basis of the control group.
the experimental group used Extracorporeal Diaphragm Pacing (EDP) combined with Tilt Table Verticalization (TTV) on the basis of the control group.
