54例重症肺部感染的病原学分析

54 Cases of Severe Pulmonary Infection in Etiology

目的分析重症肺部感染病原体的构成,为重症肺部感染患者的早期适当经验性抗生素治疗提供重要临床依据。方法对54例重症肺部感染患者痰标本接种于血琼脂培养基培养,进行病原学检测分析。结果 54例重症肺部感染患者病原体检测,革兰阴性杆菌20例占37.0%,革兰阳性球菌24例占44.4%,肺炎支原体10例占18.5%;其中,革兰阳性球菌最常见者为金黄色葡萄球菌,12例占革兰阳性球菌的50%。结论病原学检测的重要意义之一在于可能改变经验性的治疗方案,并进而改善患者的预后。

Objective Analyze the the composition of severe pneumonia pathogens,thus to lay a clinical foundation for initial appropriate empirical antibiotic therapy on the patients of severe pneumonia.Method Cultivate the sputum samples（from 54 severe pneumonia patients） which are inoculated into blood agar culture medium and make a pathogenic analysis.Results In the pathogenic analysis of 54 severe pneumonia patients,gram-negative bacillis accounts for 37.0%（20 patients）,grams-positive cocci accounts for 44.4%（24 patient） and mycoplasma pneumoniae accounts for 18.5%（10 patients）.Most of the G＋ cocci are staphylococci aureus,which accounts for 50%（12 patients）.Conclusion The pathogen analysis plays a significant role for it may change the empirical therapy and thereby improves the prognosis.
