呼吸机相关性肺炎危险因素临床分析及预防对策

Clinical analysis on risk factors of ventilator-associated pneumonia and preventive measures

目的探讨引起呼吸机相关性肺炎相关因素及预防对策。方法分析210例应用呼吸机治疗患者的临床资料,根据呼吸机相关性肺炎诊断标准进行判断,比较呼吸机相关性肺炎患者(观察组)与未发生呼吸机相关性肺炎患者(对照组)在相关因素上差异。结果 210例发生呼吸机相关性肺炎共40例(19.04%),观察组平均年龄(60.33±12.67)岁、应用抑酸剂77.50%、APACHEⅡ评分平均(26.34±4.23)、平卧位47.50%、机械通气时间(8.39±2.56)天高于对照组的(46.46±11.75)岁、57.65%、40.00%、(21.29±3.17)、17.65%、(5.17±2.02)天(P<0.05),是引起呼吸机相关性肺炎的危险因素。结论呼吸机相关性肺炎发生率较高,与多种因素有关,应采取相应的预防对策减少呼吸机相关性肺炎的发生。

Objective To study the related factors of ventilator- associated pneumonia and the preventive measures. Methods The clinical datas of 210 cases those who were treated with ventilator were collected,the diagnosis of ventilator- associated pneumonia according to the standard of diagnosis of pneumonia absorption correlation,compared the differences of factors induced ventilator associated pneumonia between observation group and control group. Results 40 in 210 cases with ventilator- associated pneumonia（ 19.04%）,average age of the observation group was（ 60. 33 ± 12. 67） years old,acid agent applied in 77. 50%,APACHE II score was（ 26. 34 ± 4. 23）,47. 50% of the patients taken supine position,the mechanical ventilation time was（ 8. 39 ± 2. 56） days,these were higher than the control group（ 46. 46 ± 11. 75 years old,40%,21. 29 ± 3. 17,17. 65%,5. 17 ± 2. 02 days,P〈0. 05）. And they were the risk factors of ventilator associated pneumonia. Conclusions The incidence of ventilator- associated pneumonia is high. It related to several factors,corresponding preventive measures should be taken to reduce the incidence of ventilator associated pneumonia.
