Abstract：Objective To investigate the impact of oral bacterial translocation by endotracheal intubation on pulmonary infection in patients undergoing selective thoracic anesthesia surgery and efficient measures to reduce pulmonary infection. Methods Three hundred and seventeen patients undergoing selective thoracic anesthesia surgery in 2010 were randomly divided into two groups: control group (181 cases with no preoperative oral cleaning treatment) and study group(136 cases with preoperative oral cleaning). The cleaning process was a two-round mouthwash with 1% -1.5% hydrogen peroxid, with 20-30 seconds each round. Data of pulmonary infection of patients were collected within the first post-operation week. Results Pulmonary infection occurred in 28 cases of 181 control patients during 1 week after operation, the infection rate was 15.5%. While pulmonary infection occurred in 9 cases of 136 patients in study group, the infection rate was 6.6%. The pulmonary infection rate was significantly lower in experimental group than in control group (P＜ 0.05). Conclusion The mouthwash using oral disinfectant can significantly reduce the oral bacteria population and the incidence rate of lung infection by prohibiting their translocation to lung.
