肿瘤患者PICC导管相关感染影响因素的分析

目的分析肿瘤患者PICC导管相关感染影响因素，为预防感染提供理论依据。方法对189例留置PICC导管的肿瘤患者进行临床分析和细菌培养，分析年龄、穿刺技术、固定方法、导管维护周期、留置时间、导管移动、化疗方法、穿刺部位8个影响因素对感染的影响。结果189例患者中共有23例细菌培养阳性，感染率为12.1%；其中导管维护周期、导管移动与肿瘤患者PICC导管感染相关，是感染发生的危险因素。结论针对性的注意肿瘤患者PICC导管的维护和减少导管移动能有效预防导管相关感染。

Analysis on risk factors for PICC catheter-related blood stream infections in tumor patients

Objective To explore the risk factors for PICC catheter-related blood stream infections in tumor patients so as to provide the evidence for optimizing the nursing measures and implementing the prevention. Methods Selected 189 cases of tumor patients indwelling PICC catheters for the study, all patients give in clinical analysis and bacterial culture. To analyzing age, puncture technique, fixation methods, catheter maintenance cycle, indwelling time of catheter movement, chemotherapy the impact of factors on the infection. Results 189 cases of patients with a total of 23 cases of bacterial culture positive, the infection rate was 12.1%; the catheter maintenance cycle and moving the catheter PICC catheter are risk factors for infection. Conclusion Attention and reducing maintenance of PICC catheter movement can effectively prevent catheter-related infections.
