Abstract:

Objective To analyze the oral status of children with tracheal intubation in different time periods afteroral care with chlorhexidine,and to select the best oral care plan. Methods 63 children who met the included criteria in the Children Intensive Care Unit were selected. The patients received oral care with chlorhexidine by solution washing and scrubbing, pharyngeal swab culture was carried out for the oral cavity before oral care ,2 hours,4 hours,6 hours and 8 hours after oral care respectively. Results According to the analysis of swab results,15 cases had pathogenic bacteria in the oral cavity. The number of bacterial strains was lowest 2 hours after oral care ,and highest 8 hours after oral care. The number of bacterial strains increased with time ( x2=1.825,P=0.171). The rise was slow 2~6 hours after oral care ,and the rise trend became rapid 6~8 hours after oral care.The total number of oral bacteria decreased dramatically 2 hours after oral care. After oral care , the total number of bacterial strains increased with time , showing a stable increasing trend (x=4.841 ,P=0.028). Conclusion Oral care by chlorhexidine solution washing and scrubbing every 6 hours will improve the oral bacteria status of children with mechanical ventilation.
