院内肺部感染病原菌及药敏分析

ANALYSIS OF THE PATHOGENIC BACTERIA OF PULMONARY INFECTION AND ITS DRUG SENSITIVITY

目的了解医院内肺部感染病原菌的排序及细菌的耐药情况。方法全部病例进行痰液病原菌培养+药敏试验,并经胸片证实为肺炎的病例为入选分析对象。结果在院内肺部感染414例患者中痰培养分离阳性例数275例,分离出40余种病原菌,分离阳性率为66.43%(275/414),病原菌仍以革兰阴性菌为主,革兰阴性菌种占居前十位菌种的90%,以铜绿假单胞菌分离阳性比例最大,占居前十位菌种分离阳性例数的31.35%。按医院常用抗生素作药敏分析,多数革兰阴性菌对头孢他啶、头孢哌酮等相对敏感,而加酶抑制剂抗菌药物如头孢哌酮/舒巴坦使细菌耐药性明显下降。结论医院内肺部感染仍以革兰阴性菌为主,而细菌产生β内酰胺酶仍然是耐药性产生的主要原因。

Objective Understand row preface and the bear of germ medicine circumstance of the lung department infection cause germ inside the hospital. Methods All cases earry on the phlegm liquid cause germ development ＋ the medicine be quick to experiment, and through chest slice the case which confirm for the pneumonia for select analysis object. Results The phlegm development separates male number 275 in lung department inside the hospital the infection 414 sufferers, separate 40 remainings to grow cause germ, separate the masculine gender rate as 66.43% （275/414）, the cause germ still regards the Ge orchid feminine gender germ as principle, the Ge orchid feminine gender germ kind have to occupy ten ex - germs grow of 90% , separate a male eomparison by the copper green and false single afterbirth germ biggest, have to occupy ten ex - germs to grow to separate male number of 31.35%. Press the hospital in common use antibiotics to make the medicine quick analysis, the most C.e orchid feminine gender germ enemy opponent Bao his Ding, head Bao Mao Tong etc. opposite sensitive, hut add the anti - virus medicine of the Mao depressant such as head Bao Mao Tong/comfortable Ba Tan3 make the germ bear a medicine to descend obviously. Conclusion Lung inside the hospital but infection still regard the Ge orchid feminine gender germ as principle, but germ creation the Mao An in the β the Mao still keep ising the main reason which bears a medieine a creation.
