气管套管内留置负压吸痰管的吸痰效果分析

Effect analysis of negative pressure suction tube suctioning tracheal tube indwelling

目的探讨持续负压吸痰在气管切开呛咳有力患者中的应用效果。方法将110例气管切开患者随机分为对照组和实验组各55例,对照组采用传统的吸痰方法进行气管套管内吸痰,实验组采用气管套管内留置负压吸痰管吸痰,比较两组患者吸痰前、后的血氧饱和度(SpO2)、呼吸频率,吸痰后刺激性咳嗽、气管黏膜出血、痰鸣音、呼吸困难情况。结果对照组和实验组吸痰前SpO2和呼吸频率比较差异均无统计学意义(均P>0.05),对照组和实验组吸痰后SpO2和呼吸频率均值比较差异均有高度统计学意义(均P<0.01);实验组吸痰前、后的SpO2和呼吸频率均值比较差异均有高度统计学意义(均P<0.01);对照组吸痰前、后的SPO2和呼吸频率均值比较差异无统计学意义(均P>0.05);实验组吸痰后患者出现刺激性咳嗽、气管黏膜出血、痰鸣音、呼吸困难人数、3 d后痰量明显少于对照组,两组比较差异有高度统计学意义(均P<0.01)。结论气管切开患者吸痰后气管套管内留置负压吸痰管吸痰法效果明显优于传统吸痰法,值得临床推广应用。

Objective To explore the application effect of continous negative pressure sputum suction for the tra- cheotomy patients who were choking strong. Methods There were 110 tracheotomy patients were randomly divided to two groups. 55 of them made up a control group and the others made up the experiment group. The traditional method of sputum aspiration was used for the control group, while the tracheal casing remaining negative pressure sucking phlegm sputum suction tube was used in the experiment respiratory rate befor and after sputum suction, but also group. It was not only to compare their oxygen saturation and the irritating cough btracheal mucosa, bleeding, sputum, the degree of difficulty breathing. Results There were no abvions diferences between the two groups on the oxygen satura- tion and respiratory rate before suctioning （P 〉 0.05）, but there were significant differences about the oxygen saturation and respiratory rate in the control group and experimental group after sputum suction （P 〈 0.01）. Significantly dif- ference were presented on the average of SpO2 and respiratory rate in the experimental group before and after sputum suction （P 〈 0.01）; oppositly, there was no abvious diference in the control group （all P 〉 0.05）. As far as the experi- mental group was concerned, irritating coughb tracheal mucosa, bleeding, sputum, the degree of difficulty breathing were appeared after sputum suction, but the putum volume was After comparing the two groups, there were obvious statistical significantly less than the control group three days later. significance （all P 〈 0.01）. Conclusion The indwelling tracheostomy tube in patients with tracheotomy suction negative pressure suction tube to the suction method is superior to a traditional suction method. It is worthy of clinical application.
