NIV Intolerance Clinical Trial
Official title:
Evaluation of Remifentanil and Dexmedetomidine in Patients With Noninvasive Mechanical Ventilation Intolerance After Cardiac Surgery: a Multicenter, Prospective, Single-blind, Randomized Controlled Study
Currently, NIV(Noninvasive ventilation ) is widely used in patients with hypoxemia and atelectasis after cardiac surgery.About 15% of patients have intolerance during NIV. The main manifestation is that the patient feels uncomfortable, often breaks away from the mask, and even gradually becomes agitated, which eventually leads to the failure of non-invasive ventilation.The patient's intubation rate is as high as 44%, and the mortality rate is 34%.There are many ways to prevent or treat NIV intolerance, of which the most used is to sedate the patient. This study aims to evaluate the effects of remifentanil and dexmedetomidine in the sedation of patients with intolerance to non-invasive mechanical ventilation after cardiac surgery, and to explore the optimal plan for sedation of patients with intolerant non-invasive mechanical ventilation after cardiac surgery.
