The effects of 4 different clinical factors on endotracheal cuff pressure / 中华护理杂志

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.
