摘要
目的:探讨在机械通气条件下不同的气管导管气囊压力与呼吸机相关性肺炎发生率的关系。方法:将120例ICU病房内进行机械通气的患者随机分为四组,使用专用气囊测压表测量气囊压力分别为I组20 cm H_2O(1cm H_2O=0.0098 k Pa)、Ⅱ组25 cm H_2O、Ⅲ组30 cm H_2O、Ⅳ组35 cm H_2O,测定不同压力水平下呼吸机相关性肺炎的发生率,从而测定气管导管的最佳气囊压力,对其数据用SPSS13.0统计软件进行统计学分析。结果:Ⅲ组呼吸机相关性肺炎的发生率最低,Ⅱ组、Ⅳ组发生率相近,Ⅰ组发生率最高。结论:机械通气时气管导管内气囊压力最佳值为30 cm H_2O,发生呼吸机相关性肺炎的几率最低。
Objective To explore the relationship between different endotracheal tube cuff pressures and ventilator-associated pneumonia（VAP） incidence under mechanical ventilation condition. Method 120 mechanically ventilated ICU patients were randomly divided into four groups based on their different cuff pressures. Special cuff pressure gauge was used to measure the pressures. The pressure of Group Ⅰ was 20 cm H2O（1 cm H2O = 0. 0098 k Pa）,that of Group Ⅱ was 25 cm H2O,that of GroupⅢ was 30 cm H2O,and that of Group Ⅳ was 35 cm H2O. The incidences of ventilator-associated pneumonia at different pressure levels were recorded,so as to determine the optimal endotracheal tube cuff pressure. Statistical analysis was performed by SPSS13. 0. Results Ventilator in group Ⅲ caused the lowest incidence of ventilator-associated pneumonia,Group Ⅱ and GroupⅣ had similar indidences,while Group Ⅰ showed the highest incidence. Conclusion During mechanical ventilation,the optimal endotracheal tube cuff pressure is 30 cm H2O,which has the lowest probability to cause ventilator-associated pneumonia.
