心血管外科术后300例中心静脉插管致病菌分析

目的了解心血管外科术后中心静脉导管相关的致病菌分布状况. 方法 1998年6月及2001年9月、2002年10月间,分别3次对共计300例中心静脉导管全部进行尖端半定量、皮下段的定性培养. 结果中心静脉导管尖端致病菌感染率12.3%,导管尖端致病菌定居率8%,皮下段致病菌培养阳性率14%,革兰阳性球菌>80%;中心静脉导管致病菌检出率与导管的留置时间明显相关(>5 d). 结论中心静脉导管作为重要的致病菌感染途径,应引起足够的重视.

Pathogen Culturing of Central Venous Catheters:A Clinical Analysis of 300 Cases after Cardiovascular Surgery

OBJECTIVE To investigate the pathogen culturing of the central venous catheter after cardiovascular surgery. METHODS On Jun 1998, Sep 2001 and Nov 2002, a total of 300 cases (100 cases by each time) central venous catheters were determined, when the cusp of the catheters was determined by semi-quantitative bacteria culture, and subcutaneous part of catheters by qualitative bacteria culture. RESULTS The cusp of central venous catheter pathogen infection rate was 12.3%, pathogen colonized rate was 8%; the subcutaneous part of central venous catheter positive pathogen rate was 14%. More than 80% pathogens were staphylococci. There was a significant deference between the stayed times of central venous catheter (>5 d). CONCLUSIONS As a special important infection access, the central venous catheters take an important role, and should be taken seriously by the doctors.
