The application of sputum suction by tracheal intubation via nasal approach on the patients with acute deteriorating cor pulmonale

Objective To explore the application and effect of sputum suction by tracheal intubation via nasal approach on patients with acute deteriorating chronic cor-pulmonale.Methods A total of 100 cases of patients with acute deteriorating chronic cor-pulmonale in our hospital were randomly divided into observation group ( 50 cases ) and control group (50 cases ). The observation group was received sputum suction by tracheal intubation via nasal.Control group was sputum drainage via nasal directly.The times and the quantity of sputum drainage in 24 hours and the effect on oxyhemoglobin saturation and myocardial oxygen consumption were observed.Results As compared with control group, there were significant difference in observation group as following :the times and the quantity of sputum drainage in 24 hours,the occurrence of mucosa injury, the effect on oxyhemoglobin saturation and myocardial oxygen consumption. There were statistical differences before and after aspiration of sputum in HR, SBP and myocardial oxygen consumption. Those of observation group were better than those of control group.Conclusions The effect of sputum suction by tracheal intubation via nasal approach was better than that of traditional way of sputum suction. It could clean the sputum retention, improve ventilation function, reduce hypoxemia and mucosa injury caused by suction, reduce myocardial oxygen consumption, improve oxyhemoglobin saturation. Key words: Acute deteriorating cor pulmonale;  Sputum suction by tracheal intubation via nasal sputum;  Oxyhemoglobin saturation;  Myocardial oxygen consumption
