密闭式吸痰管在机械通气患者治疗中的疗效观察

The therapeutic effects of Closed Tracheal Suction Catheter to the patients on mechanical ventilation

目的研究更适合机械通气患者气管内吸痰的方式。方法选取外科重症监护病房（SICU）和急诊重症监护病房（EICU）机械通气治疗的61例患者为研究对象，随机选择使用密闭式气管内吸痰（CS）和开放式气管内吸痰（OS）两种吸痰方式，于吸痰前后记录脉搏血氧饱和度（SpO2）的变化并比较两组患者并发症例数。结果吸痰中、吸痰后0．5minOS治疗组各时点SpO2值较吸痰前1min下降明显（P〈0．05），CS治疗组吸痰前后SpO2值无显著差异（P〉0．05）。两组并发症比较无显著差异（P〉0．05）。结论CS对机械通气患者更有利。

Objective To find a better way of endotracbeal suction and care in patients on mechanical ventilation. Methotis Sixty - one patients who were on mechanical ventilation in SICU or EICU were divided at random into the CS （ closed endotracbeal, suctioning） group （therapeutic group, 30 patients） and the OS （open endotracbeal suctioning） group （contrast group, 31 patients）. The data of oxygen saturation by pulse oximetry（ SpO2 ） were obtained before and after suction. The cases of complication incidence were compared between two groups. Results There was a significant decrease in SpO2 after OS （ P 〈 0.05 ）. The differences were not statistically significant before and after CS. There was no differences in complication incidence between two groups （P 〈 0.05） . Conclusion CS has a good therapeutic effect for patients on mechanical ventilation.
