Clinical application of natrium bicarbonate solution as a humidification agent in artificial airway of mechanically ventilated patients

Objective To explore the effects of sodium bicarbonate solution as a humidification agent in artificial airway so as to provide references of artificial airway nursing. Methods A total of 200 patients with artificial airway were enrolled. 2.5% natrium bicarbonicum and O. 9% saline liquid were used as airway instillation solution before suction respectively in every patient. Blood pressure, heart rate, blood gas analysis and the condition of sputum were collected before and after suction. Results There were statistically significant differences in characteristics of sputum, before and ＇after instillation of two kinds of airway humidification fluid in airway. BE and HCO3 had statistically significance before and after instiuation of sodium bicarbonate in airway （ P 〈 0. 05 ） , but the blood pressure and heart rate had no effect （ P 〉 0. 05 ）. Conclusion Application of sodimn bicarbonate solution as a humidification agent in artificial airway can dilute sputum and is beneficial for sputum suction. At the same time ,it has no effect on heart rate and blood pressure,but it can act on BE and HCO3 -. So sodi- um bicarbonate solution should be cautious to use as humidifier in artificial aft＇way management.
