The Relationship Between Smoking And Pulmonary Infection Rate Of Severe Craniocerebral Injured Patients

Objective: To investigate the relationship between smoking and pulmonary infection rate ofsevere craniocerebral injured patients，and understand its prognosis condition. Method: Total236cases of patients complicating with cerebral hernia during Jan2006to June2012wereselected,51cases of patients complicating with pulmonary infection and185cases ofpatients without pulmonary infection were studied by case control study, their smokingcondition and influence for prognosis of the two groups were compared. There are notsignificance using F-test and X2analysis between the two groups of cases in GCS score andthe severity of the disturbance of consciousness. The two groups have no difference intreatment and the severity of disease, and they are not considered to have significance(P>0.05). Lastly, the cases of smoking or without smoking, the smoking time and smokingcondition will be analysis.Result: The rates of infection group of smoking was60.8%, and the control group smokingrate was35.7%. There was statistically significant (P=0.001) between the two group. Thesingle factor regression analysis showed that the risk was2.749times than non-smokers.Theywill be divided into four groups: less than or equal to5years, less than or equal to10years,less than or equal to15years and more than15years. They were significance between thetwo group (P=0.001). The single factor regression analysis also showed that smokers whoincreased five years in smoking was1.39times that of non-smokers, The smoking conditionwas not statistically significant.Conclusion: Smoking and smoking time are important factors for sever craniocerebralinjured patients to complicate with pulmonary infection. There will be more risk for patientssmoking than non-smokers, and the much time of smoking, the more risk of pulmonaryinfection for craniocerebral injured patients.
