Nursing of patients with acute respiratory distress syndrome receiving constant small amount of continuous airway humidification and closed suction method for prevention of sputum formation / 中国实用护理杂志

ABSTRACT

Objective To investigate the effect of constant small amount of continuous airway humidification and closed suction method to prevent sputum formation of patients with acute respiratory distress syndrome. Methods 115 cases with acute respiratory distress syndrome were randomly divided into the observation group (60 cases)and the control group (55 cases).The observation group was given small amount of constant continuous airway humidification and closed suction method.The control group was given open suction and intermittent airway humidification.The treatment effect was compared between the two groups. Results 24 h after intubation,difference of sputum viscosity between the two groups was not significant.72 h and 120 h after intubation,sputum viscosity of the control group was significantly higher than the observation group.In the sputum formation,24 h,72 b and 120 h after intubation,the control group was significantly higher than the observation group.At the end of suction,and 1 min,3 min,5 min after the suction,the oxygen saturation degree of the observation group was significantly higher than the control group.Whatever in the process of humidification or suction,the incidence of adverse reactions in the observation group was significantly lower than the control group,the difference was obvious. Conclusions Combination of constant small amount of continuous airway humidification and closed suction method can effectively reduce the sputum formation of patients with acute respiratory distress syndrome,which is worthy of clinical promotion.
