Effect of selective oral decontamination on preventing ventilator-associated pneumonia / 中国感染控制杂志

ABSTRACT

Objective To evaluate the effect of selective oral decontamination (SOD)on reducing incidence of ventilator-associated pneumonia (VAP).Methods Sixty patients hospitalized in an intensive care unit (ICU)for >72 hours and with mechanical ventilation for >48 hours from January to June 2102 were selected for study,patients were ran-domly divided into trial group(n =30)and control group(n=30).All patients received cefotaxime intravenous drip for 4 days,then trial group received oropharyngeal application of tobramycin during the whole process of mechanical ventila-tion,control group topically received saline solution,the incidence and onset time of VAP ,duration of mechanical ventila-tion,length of stay in ICU,and mortality of two groups were compared.Sputum in the trachea was taken periodically for bacterial culture.Results The incidence of VAP in trial group was lower than control group (30.00% vs 63.33%);the onset time of VAP was later than control group ([9.37±6.62]d vs [5.17 ±4.72]d);Overall duration of me-chanical ventilation was less than control group ([7.63 ±6.91 ]d vs [12.26 ±9.36]d);length of stay in ICU was shorter than control group([13.56±7.22]d vs [16.79±11 .16]d)(all P 0.05).Conclusion SOD is effective for preventing and treating VAP,it can reduce the incidence of VAP,delay onset time of VAP,shorten mechanical ventilation,and reduce length of stay in ICU.
