经胸前区腋静脉穿刺置管导管相关性感染调查研究

目的探讨经胸前区腋静脉穿刺置管(IATAV)病人导管相关性感染情况。方法2001年10月～2003年10月对接受IATAV的707例病人进行导管相关性感染调查。结果发生导管相关性感染5例,感染率为0.71%,其中外科650例病人,感染1例,感染率0.15%,化疗科57例病人,感染4例,感染率7.02%;全组病人置管时间<20d者共646例,发生感染1例,感染率为0.15%,≥20d者共61例,发生感染4例,感染率6.56%。结论IATAV病人导管相关性感染的主要危险因素为机体免疫功能低下、置管时间长和导管护理欠妥,对有高危因素存在的病人要加强监测和护理,避免发生导管感染。

Investigation of catheter-related infections in intubation by anterior thoracic wall axillary venipuncture

Objective To study the catheter-related infections in patients receiving anterior thoracic wall axillary venipuncture (IATAV). Methods Catheter-related infections were investigated in 707 patients with IATAV between Oct. 2001 and Oct. 2003. Results Five cases had catheter-related infection and the infection rate was 0.71%. One case was infected in 650 surgical patients and the infection rate was 0.15%. Four cases were infected in 57 chemotherapy patients and the infection rate was 7.02%. In 61 patients,the catheter was in place over 20 days. Among them,4 cases were infected and the infection rate was 6.56%. Conclusions The study showed that catheter-related infection for IATAV occurred because the patients' immunity was poor,the catheter was in place too long and the catheter care was insufficient. Patients with high risk factors should be monitored and be given better care in order to prevent severe catheter-related infections.
