【摘要】 目的探讨吸痰、翻身、口腔护理及吞咽对人工气道气囊压力的影响,为更好地进行气囊管理提供依据。方法应用压力传感器持续监测气囊压力,观察吸痰、翻身、口腔护理过程中气囊压力的变化,记录活动前、活动时、活动后5 min、15 min、30 min的气囊压力值;另外观察吞咽对气囊压力的影响,观察时间点为吞咽前、吞咽时、吞咽后1min、5 min、10 min。结果吸痰时、吸痰后5 min气囊压力高于吸痰前,翻身时、翻身后5 min气囊压力高于翻身前,口腔护理时气囊压力高于口腔护理前,吞咽时气囊压力高于吞咽前,差异均有统计学意义(P<0.05)。结论吸痰、翻身、口腔护理、吞咽会导致气囊压力出现短暂性升高,瞬时的压力增高可能会误导医务人员对气囊安全性的判断,建议在此期间不可盲目调整气囊压力,以免增加漏气和误吸的风险。更多还原

【Abstract】 Objective To investigate the effects of endotracheal suctioning,turning over,oral caring and swallowingon cuff pressure,so as to provide evidence for the management of the endotracheal cuff.Methods During continuous monitoring of cuff pressure with pressure sensor,the changes of cuff pressure were recorded in the process of endotracheal suctioning,turning over,and oral caring.The data of cuff pressure were recorded including before activity,during activity,after activity for 5 min,15 min and 30 min.In addition,the data of cuff pressure were recorded including before swallowing,during swallowing,after swallowing for 1 min,5 min and 10 min.Results The cuff pressure during endotracheal suctioning and after endotracheal suctioning for 5 min was higher than that before endotracheal suctioning,the difference was statistically significant(P<0.05);the cuff pressure during turning over and after turning over for 5 min was higher than that before turning over,the difference was statistically significant(P<0.05);the cuff pressure during the oral caring was higher than that before oral caring,the difference was statistically significant(P<0.05);the cuff pressure during swallowing was higher than that before swallowing,the difference was statistically significant(P<0.05).Conclusion These clinical factors would lead to transient increase of cuff pressure including suctioning,turning over,oral caring,and swallowing.The instantaneous cuff pressure will mislead the staff to judge the safey of endotracheal cuff.The cuff pressure should not be blindly adjusted,so as to avoid the risks of leakage and aspiration.更多还原
