High-dose Inhaled NO Therapy for the pREvenvention of NP After Cardiac Surgery Under CPB
The primary aim of this single-center, prospective, randomized, controlled, study is to test the hypothesis that inhalation of NO 200 ppm prevents the development of nosocomial pneumonia in patients at risk after cardiac surgery under CPB. The study is interventional. Examination and treatment of patients is carried out in accordance with the approved standards of medical care for the relevant diseases. During the study, no experimental or unregistered (not approved for use) medical or diagnostic procedures in the territory of the Russian Federation will be carried out. The study includes patients admitted to the Cardiac Surgery Department of Cardiology Research Institute of Tomsk National Research Medical Center for elective surgery with CPB.
