摘要
目的探讨ICU机械通气患者每2h翻身前行口咽部吸引对降低呼吸机相关性肺炎(VAP)的影响。方法 ICU机械通气患者随机分为试验组和对照组,试验组每2h翻身前行口咽部吸引,对照组在有可视分泌物时才吸引。比较两组机械通气时间、住ICU时间、口咽部分泌物吸引量、VAP发生情况和住院期间的病死率等指标。结果试验组1周内发生VAP的例数、发生的时间、机械通气时间、住ICU天数等均低于对照组,两组差异有统计学意义(P<0.05);两组口咽部分泌物吸引量、住院期间的病死率比较,差异无统计学意义(P>0.05)。结论 ICU机械通气患者每2h翻身前行口咽部吸引,可以提高吸引效果,减少VAP的发生率。
Objective To compare the effects of different suction patterns in critically ill patients with mechanical ventilation. Methods Eighty-four mechanically ventilated patients were recruited from the Intensive Care Unit（ICU）. They were divided into the experimental group with oropharyngeal suction every two hours before position changing（n=41） and the control group with immediate oropharyngeal suction when the secretions were visible（n=43）. The duration of mechanical ventilation,the length of ICU stay,the volume of oropharyngeal secretions,the incidence of ventilator-associated pneumonia（VAP） and the mortality were recorded. Results The incidence of VAP within one week,the average duration of mechanical ventilation,the average length of ICU stay were significantly different between the two groups（P〈0.05）. There were no significant differences in the volume of oropharyngeal secretions and the mortality between the two groups（P〉0.05）. Conclusion Oropharyngeal suction before turning over can not only improve the suction effectiveness,but also reduce incidence of VAP, length of ICU stay and the duration of mechanical ventilation.
