经胸前区腋静脉置管感染危险因素分析

目的：探讨经胸前区腋静脉穿刺置管患者导管相关性感染危险因素。方法：对707例经胸前区腋静脉穿刺置管患者进行调查，感染病例导管尖端及血液送细菌培养。结果：发生导管相关性感染5例，感染率为0．7％，其中外科650例患者，感染1例，感染率0．15％，化疗科57例患者，感染4例，感染率7．02％。全组患者置管时间≥20d者共61例，发生感染4例，感染率6．56％。结论：经胸前区腋静脉穿刺置管患者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，对有高危因素的患者要加强监测和护理，避免导管感染的发生。

The risk factor of infections in intubation by anterior thoracic wall axillary venipunctrue

Objective: To study the risk factors of infections in Intubaiton by Anterior Thoracic Wall Axillary Venipuncture (IATAV).Methods: 707 patents with IATAV catheters were studied. Bacterial culture were performed at catheter's end and blood culture after removing the catheter in infection cases. Results: 5 caes had catheter-related infection and the infection rate 0.7%.1 case was infected in 650 surgical patients and the infection rate was 0.15%. 4 cases were infected in 57 chemotherapy patients and the infection rate was 7.02%. 4 cases were infected in 61 patients that the catheter in place longer than 20 days and the infection rate was 6.56%. Conclusions: The study showed that the main causative factors of catheter-related infection for IATAV were that of the paients' lower immunity, long placement of catheter as well as insufficient nursing care. So the patients with risk factors should be monitored and better cared in order to prevent severe catheter-related infections.
