Summary

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.

Conditions

  • NIV Intolerance

Interventions

DRUG

Remifentanil

Intravenous pump injection.The initial dose of remifentanil is 0.05 μg/kg/min.The drug dosage will be adjusted according to the subjects' intolerance relief (the treatment target is NIS ≤ 2), and the maximum dosage of remifentanil is 0.12 μg/kg/min

DRUG

Dexmedetomidine

Intravenous pump injection.The initial dose of dexmedetomidine is 0.5 μg/kg/h.The drug dosage will be adjusted according to the subjects' intolerance relief (the treatment target is NIS ≤ 2), and the maximum dosage of dexmedetomidine is 1.0 μg/kg/h.
