Specific Small RNA in Plasma for Predicting Diaphragm Dysfunction in Mechanically Ventilated Patients

Observational Study of Specific Small RNA in Plasma Muscle Tissue for Predicting Diaphragm Dysfunction in Mechanically Ventilated Patients

Through the literature screening of MyomiRX 7, the detection of mechanical ventilation group, difficult withdrawal unit and healthy adult plasma levels of MyomiRX in the evaluation of function and skeletal muscle thickness of the diaphragm, the correlation analysis of 7 kinds of MyomiRX and diaphragmatic dysfunction. The research value of this project is to explore the predictive value of plasma MyomiRX level on diaphragmatic dysfunction in patients with mechanical ventilation, and to lay the foundation for finding the target of VIDD diagnosis and treatment

Study Overview

• Status: Unknown
• Conditions: Mechanical Ventilation Complication
• Intervention / Treatment: Other: no Intervention

Detailed Description

1. research content (1) screening MyomiR through literature review (2) selection of mechanical ventilation group, difficult withdrawal units and three healthy adult groups, method for the detection of plasma MyomiRX level and clinical assessment of diaphragmatic function, observation of the relationship between MyomiRX level and diaphragmatic dysfunction, prediction of plasma MyomiRX levels in patients with mechanical ventilation for diaphragmatic dysfunction in value.
2. research objectives Objective to investigate the predictive value of specific minute RNA in plasma muscle tissue on diaphragmatic dysfunction in mechanical ventilation patients Experimental grouping (1) the control group of mechanical ventilation (time of examination, preoperative, admission to ICU and before extubation); (2) difficulty in withdrawal of units (first days, third days and seventh days after the failure of the test time for the first withdrawal); (3) the healthy control group (after the test time was selected)
