血液透析患者带绦纶套长期透析导管相关感染分析

目的分析带绦纶套长期透析导管感染的细菌学和相关因素,以减少临床感染的发生。方法调查2007-12～2011-12之间所有行带绦纶套长期透析导管植入患者的临床资料,包括导管留置时间、原发病、导管相关感染情况、细菌培养结果等。结果在45例次导管植入患者中,共629导管月（19849导管日）,共发生导管相关感染15导管月,感染率为2.3%（0.756次/1000导管日）。15次导管相关感染均行细菌培养,其中15次感染细菌培养阳性,阳性率为100%,阳性菌14次,阴性菌1次。导管相关感染在糖尿病患者发生率为4.5%,非糖尿病人导管感染发生率为1.5%,二者比较χ2=4.90,P〈0.05。结论合并有糖尿病的患者导管感染发生率比未合并糖尿病的患者高,导管相关感染的致病菌以革兰氏阳性菌为主。

Analysis of catheter related infectious in dialysis patients with long- term cuffed catheter

Objective To analyze the long-term cuffed catheter related infectious bacteriology and infection related factors in the long-term dialysis patients with the aim to reduce the infectious incidence in clinical.Methods Clinical data were collected between the year 2007 and 2011 in the long-term dialysis patients.Catheter dwelling time,the primary disease,catheter-related infection,infectious bacterial were investigated.Results 45 dialysis patients treated with the long-term catheter were investigated.a total of 629 catheter months(19 849 catheter days),there were catheter-related infection 15 catheter months,the infection rate was 2.3 percent(0.756 / 1,000 catheter days).All catheter-related infection patients were adopted common Bacterial cultivation,the the positive culture rate of bacteria was 100 percent,Grams positive and negative germs of bacterial culture were 93.3 percent and 6.7 percent respectively.Catheter-related infections rate in was 4.5 percent in patients with diabetes,non-diabetic patients was 1.5 percent,Compared with patients of diabetic the infections rate were significantly lower in non-diabetic patients(χ2=4.90,P<0.05).Conclusion Our data showed that compared with patients of non-diabetic the infections rate was higher in diabetic patients.Gram-positive bacteria were the main pathogen in the catheter infection patients.
