目的：探讨气管插管患者应用1.25%碳酸氢钠冲洗气道的效果。方法用简单随机抽样法抽取气管插管脱机患者52例，采用随机数字表法分为观察组和对照组各26例。观察组用1.25%碳酸氢钠冲洗气道q 2 h，对照组用0.45%氯化钠溶液冲洗气道q 2 h。比较2组患者第3天、第5天、第7天痰黏度和日排痰量（g），7 d内气道湿化并发症的发生率。结果观察组日排痰量明显优于对照组，第7天痰黏度低于对照组，2组比较差异有统计学意义（P<0.01）。观察组7 d内肺部感染发生率为15.4%，对照组为42.3%，2组比较差异有统计学意义（P<0.05）。结论气管插管患者用1.25%碳酸氢钠冲洗气道能有效降低痰液黏度和气道并发症的发生率。

Objective Effect of rinsing airway on patients with tracheal intubation using 1.25% sodium bicarbonate.Methods 52 patients of tracheal intubation offline extracted by simple random sampling method,were divided into observation group(OG) and control group(CG)(n=26) using the method of random digits table. The OG with 1.25% sodium bicarbonate rinsing airway q2h, the CG with 0.45% saline rinsing airway q2h.Comparing the changes of patients sputum in the 3rd day, 5th day, 7th day, and comparing the incidence of humidification of airway complications within 7 days.Results The volume of expectoration drainage of the OGwas less than that of the CG, and the sputum viscosity of the OG is lower than that of the CG, the difference was statistically significant (P<0.01). The incidence of pulmonary infection within 7 days of the OG was 15.4%, but 42.3% of the CG, the difference was statistically significant (P<0.05) too.Conclusions The method of rinsing airway with 1.25% sodium bicarbonate on endotracheal intubation patients can effectively reduce the sputum viscosity and the incidence of humidification of airway complications.
