目的：探讨不同吸痰方法对降低机械通气患者肺部感染发生的影响。方法将466例机械通气患者随机分为研究组219例，对照组247例，对照组采.用开放式常规吸痰方法，研究组采.用封闭式负压吸痰法，比较两组患者肺部感染发生情况。结果研究组患者肺部感染发生率为8.2%低于对照组14.6%，两组比较，χ2＝4.58，P＜0.05，差异具有统计学意义。结论与传统开放式常规吸痰方法相比，封闭式负压吸痰法对降低机械通气患者肺部感染的发生具有重要意义。

Objective To investigate the effect of different sputum suction methods on the incidences of pulmonary infections in patients with mechanical ventilation.Methods Four hundred and sixty-six patients with mechanical ventilation were randomly divided into study group(n=219)and control group(n=247).The two groups were treated with continued balloon filling and airway humidification.Besides,the control group received conventional open sputum suction and the study group closed continuous negative pressure sputum suction.The two groups were compared in terms of incidence of pulmonary infections.Result The incidence of the study group(8.2%)was significantly lower than that of the control group(14.6%)(χ2=4.58,P<0.05).Conclusion Compared with the traditional open conventional sputum suction method,closed continuous negative pressure sputum suction may be more effective in reducing the incidence of pulmonary infection in patients with mechanical ventilation.
