护理干预对预防呼吸机相关性肺炎的影响

摘要

Objective To investigate the influence of nursing intervention on prevention of ventilator associated pneu-monia. Methods A total of 144 patients with mechanical ventilation were divided into intervention group and control group ,72 cases in each group. The control group received routine nursing ,while the intervention group received improved nursing based on the control group. To compare the mechanical ventilation time ,the incidence rate of ventilator associated pneumonia and treatment results of the two groups. Results The average mechanical ventilation time was 22.1 days in the intervention group and 36.2 days in the control group;ventilator associated pneumonia occurred in 8 cases in the intervention group accounting for 11.1%and 18 cases in the control group accounting for 25.0%;the differences of mechanical ventilator associated pneumonia and incidence rate between the two groups both had statistical significance(P<0.05). 1 h after treatment and removal of mechanical ventilation,the intervention group was obviously better than the control group on arterial blood gas analysis ,respiration and heart rate with statisti-cally significant difference(P<0.05). Conclusion During treatment of mechanical ventilation,application of improved nursing intervention can shorten mechanical ventilation time ,reduce the incidence rate of ventilator associated pneumonia ,improve the treatment result,and it has significant clinical implications.%目的：探讨护理干预对预防呼吸机相关性肺炎的影响。方法将144例机械通气患者分为护理干预组72例和对照组72例。对照组按常规护理，干预组在常规护理的基础上给予改进的护理措施。比较两组的机械通气时间、呼吸机相关性肺炎的发生率及治疗效果。结果干预组平均机械通气时间为22.1 d，对照组为36.2 d；干预组发生呼吸机相关性肺炎8例，发生率为11.1％，对照组发生呼吸机肺炎18例，发生率为25.0％。以上2项比较，差异均有统计学意义（P<0.05）。经治疗并撤除机械通气1 h后，在动脉血气分析、呼吸、心率方面，干预组较对照组有明显改善，差异均有统计学意义（P<0.05）。结论在患者机械通气治疗期间，实施改进的护理干预措施，有助于缩短机械通气时间，降低呼吸机相关性肺炎发生率，提高治疗效果，具有明显的临床意义。
