Risk factors and control strategy for general anesthesia tracheal intubation related pulmonary infection

OBJECTIVE To investigate risk factors of general tracheal intubation related pulmonary infection,and to take the corresponding control measures in hospitalized patients in our general surgery department.METHODS A total of 777 hospitalized patients needing general anesthesia tracheal intubation surgery from our general surgery department were randomly divided into two groups:the patients were nottaken any special control measures before operation and self designing quality control measures were taken including oral nursing care before operation,respiratory tract management after operation and reasonable use of antibiotics in the perioperative period.The incidence rate of pulmonary infections was observed during 1 week after operation.RESULTS Pulmonary infection was occurred in 64 of 391 control patients during 1 week after operation,the infection rate was 13.8%.While pulmonary infection was occurred in 21 of 386 quality-control patients,the infection rate was 5.4%.The pulmonary infection rate was significantly lower in Quality-control group than that of control group(P0.05).CONCLUSION Oral nursing care before operation,respiratory tract management after operation and reasonable use of antibiotics are the key for quality control to prevent the occurrence of general tracheal intubation related pulmonary infection.
