【摘要】 目的分析慢性重型肝炎患者股静脉双腔导管培养的菌群分布、药敏试验,与留置时间的相关性,探讨有效的防范措施。方法对慢性重型肝炎患者行股静脉双腔导管尖端增菌培养,并同时进行外周血培养。结果双腔导管细菌培养阳性25例,64%的病原菌为葡萄球菌属。留置时间10 d以上细菌培养阳性率明显增加。结论慢性重型肝炎患者导管相关性感染发生率高,严格的无菌操作和精心护理是防治导管感染的关键。更多还原

【Abstract】 Objective To analyze the relativity between the cultured microbe distribution,sensitivity of medication and indwelling time with double-cavity catheter embedded in the femoral vein of the patients suffering from severe chronic hepatitis,furthermore to obtain effective prevention.Methods Pieces of cusp of the double-cavity catheter and the peripheral blood were both cultured and analyzed.Results 25 cases of germiculture in the double-cavity catheter were positive.64% of the pathogenic bacteria were Staphylococcus.The positive rate of germiculture was distinctly increased when indwelling time of the catheter was over 10 days.Conclusion The high incidence of infection related to catheter indwelling in chronic hepatitis patients showed that the strict administration and careful nursing were the key factor to prevent the infection.更多还原
