呼吸衰竭患者不同吸痰方式吸痰效果的比较

Comparison on the effect of mechanical ventilation with different suctioning in respiratory failure patients

目的探讨不同吸痰方式对呼吸衰竭机械通气患者吸痰前后呼吸循环参数的影响。方法将40例呼吸衰竭使用呼吸机的患者随机分为对照组和观察组，各20例。观察组采用密闭式吸痰，对照组采用传统的开放式吸痰，采取受试者自身前后对照的方法，观察患者吸痰前后呼吸循环参数的变化。结果密闭式吸痰前后患者呼吸循环参数差异无统计学意义（P〉0．05），开放式吸痰前后心率、SpO2、Ppeak、Pplat参数差异有统计学意义（P〈0.01），收缩压、RR、PaO2参数差异有统计学意义（P〈0.05），Vt、PaCO2参数差异无统计学意义（P〉0.05）。结论呼吸衰竭患者使用密闭式吸痰方法较开放式吸痰方法安全有效。

Objective To investigate the effect on the parameters of respiratory and circulatory systems in respiratory failure patients receiving mechanical ventilation by different suetioning. Methods 40 respiratory failure patients receiving mechanical ventilation were randomly divided into control group and experimental group （20 patients per group）. Individuals in experimental group were treated with closed endotracheal suctioning and the others were treated with open endotracheal suctioning. The parameters of respiratory and circulatory systems were observed before and after suctioning. All the subjects used own control. Results The parameters of respiratory and circulatory systems did not change significantly in experimental group. The heart rate, SpO2 , Ppeak, Pplat have changed significantly and the SBP, RR and PaO2 also reached the statistical significance before and after suctioning in control group. However, Vt and PaCO2 did not change significantly（ P 〉 0. 05 ）. Conclusions Respiratory failure patients treated with closed endotracheal suetioning was safer and more effective than traditional open-suctioning.
