摘要
目的分析静脉导管引起病原菌感染及相关因素。方法对医院2002年8月-2005年12月所有送检静脉导管培养的患者进行回顾性分析。结果所有送检的605例样本中,静脉导管培养阳性有149例,阳性率为24.6%;静脉导管培养阳性患者病区分布差异无统计学意义(P>0.05);对静脉导管培养阳性患者的年龄进行分段统计,老年组与非老年组比较差异有统计学意义(P<0.05);静脉导管培养阳性的病原菌中革兰阳性球菌62株,占41.6%;革兰阴性杆菌52株,占34.9%;真菌30株,占20.1%;革兰阳性杆菌5株,占3.4%;在革兰阳性球菌中葡萄球菌属51株、肠球菌属11株,在革兰阴性杆菌中非发酵菌35株、肠杆菌科细菌17株。结论静脉导管感染是引起医源性感染的重要因素之一,临床应规范操作以减低感染率。
OBJECTIVE To analyze the cases of the venous catheter bacterial infection and the correlative factors.METHODS The cultures of the venous catheter used from Aug 2002 to Dec 2005 were analyzed retrospectively.RESULTS From 605 samples,149 samples were with positive results,the positive rate was 24.6%.Their ward distribution was without statistical significance（P〉0.05）.As for patients＇ age the old age group had the statistical significance vs the non-old age group（P〈0.05）.Among the positive pathogens 62 strains were Gram-positive cocci,accounted for 41.6%,52 were Gram-negative bacilli,accounted for 34.9%,30 were fungis,accounted for 20.1% and 5 were Gram-positive bacilli,accounted for 3.4%.From Gram-positive cocci 51 strains were Staphylococcus,11 were Enterococcus.From Gram-negative bacilli 35 strains were the nonfermenters,and 17 were Enterobactericaeae.CONCLUSIONS The venous catheter infection is one of the important factors causing hospital infection.The infection rate should be decreased via the standardized manipulations.
