老年肿瘤患者PICC穿刺点周围表面r细菌定植的相关因素分析

摘要

Objective To analyze risk factors for bacterial Colonization of PICC puncture point in elderly tumor patients. Methods 142 cases of elderly cancer patients with PICC from October 2015 to January 2016 were enrolled for this study. We analyzed the relationship between the general information,the PICC maintenance information and the bacterial colonization of PICC puncture point. Results A total of 42 patients' bacterial culture were positive,and the incidence was 29.58%. Multiple factor logistic regression analysis showed that gender,proliferation,esposed tube length and blood platelet counts were risk factors of bacterial colonization of PICC puncture point in the elderly cancer patients. Conclusion Electrocardiogram should be used to located the catheter tip,and the exposed catheter length should be controlled within 4cm.Monitoring blood platelet counts and enhancing health education can reduce the occurrence of bacterial colonization of PICC puncture point.%目的 探讨老年肿瘤患者经外周静脉穿刺中心静脉置管(PICC)穿刺点周围表面细菌定植的相关因素.方法 选取2015年10月~2016年1月在解放军总医院进行PICC维护的老年肿瘤患者142例,单因素分析患者一般资料,并对穿刺点周围表面定植菌进行培养分析,将单因素有统计学意义的资料纳入多因素Logistic回归模型进行分析.结果 42例患者微生物培养结果为阳性,占29.58%.多因素分析结果发现,男性、穿刺点增生、导管外露长度>4 cm、血小板计数异常是老年肿瘤患者PICC穿刺点周围细菌定植的危险因素,OR值分别为6.042、0.204、0.265和7.594.结论 老年肿瘤患者PICC置管时应采用心电图定位,将外露长度控制在4 cm以内,对患者血小板计数进行观察,加强健康教育,以减少细菌定植,降低导管相关性感染的发生率.
