改良式拍背吸痰在呼吸机治疗重症肺炎患儿中的疗效研究

目的探讨改良式拍背后吸痰在婴幼儿重症肺炎应用呼吸机患儿治疗中的疗效。方法选择应用呼吸机治疗的小儿重症肺炎60例，随机分成对照组30例和实验组30例。实验组采用改良式拍背后吸痰，对照组采用常规式拍背后吸痰，比较两组患儿吸痰前后血氧分压（PaO2）、二氧化碳分压（PaCO2）的变化及临床疗效。结果两组患儿吸痰前PaO2、PaCO2的差异无统计学意义（P〉0．05）；吸痰后实验组PaO2（58．57±12．41）mmHg，PaCO2（42．76±10．51）mmHg，对照组PaO2（51．31±12．32）minHg，PaC02（48．98±9．86）mmHg，实验组吸痰前后血气测定的改善情况优于对照组，疗效优于对照组，差异均有统计学意义（P〈0．05）。结论采用改良式拍背后吸痰，能明显缩短重症肺炎的患儿使用呼吸机的时间及病程，提高了小儿重症肺炎的治愈率。

Study of improved type with behind burp of suctioning curative effect in using ventilator to treat with severe pneumonia

Objective To discussion the curative effect of improved type of exploring behind burp of suctioning applied in infants' evere pneumonia. Methods Select 60 cases of children used the application ventilator to treat with severe pneumonia, randomly divide into control group of 30 cases and experimental group of 30 cases . The test group was treated improved type with behind burp of suctioning,and the contrast group was treated conventional type with behind burp of suctioning. Compared the changes in PaO2、 PaCO2 and clinical curative effect before and after suctioning. Results There is no significant difference intwo groups of patients before suctioning in PaO2 、PaCO2 (P >0. 05). After suctioning in the test group PaO2 was (51. 31 ± 12. 41 ) , PaCO2 was (48. 98 ± 9. 86). The test group was better than the contrast group in improve the situation in measuring blood gas before and after suctioning . So the test group has more effective than the contrast group. The difference was statistically significant (P < 0. 05). Conclusions using the improved type behind burp of suctioning can significantly reduce the suction of children with severe pneumonia in ventilator time and duration, and increase the cure rate of children with severe pneumonia.
