RESUMEN
ObjectiveTo study the risk factors and pathogenic characteristics of ventilator associated pneumonia(YAP). MethodsRisk factors of VAP,pathogens and drug resistance in 118 patients in ICU were analyzed retrospectively. ResultsThe incidence of VAP was 44.9％, and age, the mechanical ventilation time, state of consciousness,tracheotomy,the antibiotic combination are risk factors of incidence of VAP. 53cases of VAP(68.2％ )were infected by Gram negative bacilli,25.9％ were by Gram positive cocci,and 5.9％ were by fungi. Drug resistance was observed obviously. ConclusionThe occurrence of VAP was related with multiple factors. The gram negative bacteria are the major pathogens of VAP, and the rate of drug resistance was high. The occurrence of VAP could severely affect patients' prognosis.
RESUMEN
Objective To explore the etiology of pulmonary atelectasis and explore the value of fiberoptic bronchoscope in the diagnosis and treatment of pulmonary atelectasis.Methods 192 cases of pulmonary atelectasis confirmed by thoracic X-ray and CT were examined and treated under fiberoptic bronchoscope.Results The final cause of 192 cases pulmonary atelectasis was lung cancer in 122 cases,chronic inflammation in 35 cases,tuberculosis in 24 cases,foreign body in 3 cases,blood clot obstruction in 3 cases,no clear causes in 5 cases;97.4% of pulmonary atelectasis were diagnosed.The treatment of pulmonary atelectasis caused by tumor obstruction was ineffective under fiberoptic bronchoscope;Then for others,atelectasis of patients was re-expanded completely in 65.7% after treatment one week under fiberoptic bronchoscope,re-expanded partially in 27.1% and the effective rate was 92.8%.Conclusion The rate of etiologic diagnosis of pulmonary atelectasis under fiberoptic bronchoscope is high;The main causes of pulmonary atelectasis are lung cancer,chronic inflammation and tuberculosis.The pulmonary atelectasis with no clear cause should be examined with fiberoptic bronchoscope.The treatment under fiberoptic bronchscope is effective for non-tumor atelectasis.
RESUMEN
Objective To discuss the clinical characteristics of thalamic hemorrhage,the correlative risk factor and the factors influencing prognosis.Method The clinical datas of 74 cases of thalamic hemorrhage and CT examination results were analyzed to find out the relationship between the clinical characteristics and the prognosis.Results The old age and hypertension were the main causes of thalamic hemorrhage.The mortality of thalamic hemorrhage that rupturing into ventricle was higher than that not rupturing into ventricle.Conclusions The old age and hypertension are the main causes of thalamic hemorrhage.The clinical manifestation of thalamic hemorrhage is variety.The prognosis is related weith age,blood pressure and the present of rupturing into ventricle.
