RESUMO
Objective To explore the effect of oropharyngeal airway on the fixation of oral trachea cannula in restless patients. Methods Toally 82 restless patents with oral trachea cannulation hospitalized in the two sections of ICU during January 2014 and August 2015 were involved in the study: those in the first section were assigned into the control group and those in the second into the experiment group. The former was treated with ordinary dental pad and the latter with oropharyngeal airway. The groups were compared in terms of effectiveness in fixation of the cannula and damage to oral mucosa. Result The rates of cannula displacement, oral mucosa damage in the experiment group were significantly smaller than those in the control group (P<0.05). Conclusion Oropharyngeal airway used in restless patients is effective in the fixation of oral trachea cannula and decrease the rate of oral mucosa damage and improve the comfort degree.
