摘要
目的前瞻性研究围手术期中心静脉置管后导管感染情况。方法对95例手术病人在麻醉期间放置中心静脉导管,拔管时经导管抽血并切取导管头端,分别作细菌培养及药敏试验,观察、记录导管相关性感染、血培养及导管培养结果、术后住院时间、住院费用情况。结果血培养阳性率8.42%,导管培养阳性率36.84%,导管感染率5.26%,感染者带管时间均超过72 h。60岁以上、恶性肿瘤及带管时间超过3 d的病人培养阳性率略高,但差异无显著性。培养阳性组与阴性组带管时间、术后住院天数及住院费用无明显差别。结论短期放置中心静脉导管,导管感染一般发生于72 h之后。导管及血培养结果并不影响术后住院时间及费用。
Objective To study perioperetive infection of catheter within central vein. Methods Central venous catheterization was performed in 95 patients at anesthetic stage. Blood and catheter samples were collected, at catheter removal, for bacterial culture and antibiotic sensitivity test. The results of cultures, postoperative hospital stay, and expenses were analyzed. Resuits The positive rates of blood and catheter cultures were 8. 42% and 36. 84%, respectively, catheter-related infection was 5.26 %. The infected patients were with catheter-indwelling over 72 hours, The positive culture was slightly higher in those over 60 years old, with malignant tumor and catheter indwelled more than three days. The differences between culture-positive and negative group were not significant with regard to catheter-indwelling time, hospital stay and expense. Conclusion Catheter-related infection usually occurs at 72 hours after catheterization. The results of sample culture do not impact both postoperative hospital stay and expense.
