摘要
目的探讨并分析心胸外科中心静脉导管感染的相关因素及预防对策。方法2002年1月-2005年12月，随机抽取行中心静脉穿刺患者560例。治疗结束后，取导管尖端进行细菌培养，并对结果进行分析。结果引起心胸外科深静脉置管相关感染的病原菌中，葡萄球菌占50％，真菌占16．7％；深静脉置管3，4，5周的感染率分别为24．5％、35．6％和65．2％；普胸手术及开放性胸外伤患者导管感染发生率分别为14．8％、18．0％，高于心脏手术及化疗患者；锁骨下静脉穿刺及贵要静脉置管感染发生率（9．6％、9．4％）低于颈内静脉（18．7％）。结论引起心胸外科深静脉置管相关感染的病原菌以葡萄球菌为首位病原菌；深静脉留置时间愈长，则导管感染率越高；普胸手术及开放性胸外伤患者导管感染发生率显著高于心脏手术及化疗患者；锁骨下静脉穿刺及贵要静脉置管感染发生率低于颈内静脉。严格深静脉置管护理和缩短留置时间对防止相关性感染具有重要临床意义。
Objective In order to make clear the relating factors about central venous catheterization associated infection, and then make out proper counter measures for them. Methods Selected 560 patients with central venous catheterization for bacterial culture, analyzed the results of them. Results The pathogen which had caused the central venous catheterization associated infection were staphylococcus （50.2%）and fungus （16.7%）. The incidence rate of infection when indwelled central venous catheter after 3, 4 and 5 weeks was 24.5%, 35.6% and 65.2% respectively, while in the patients who had accepted thoracic surgery or opening thoracic trauma, the incidence rate of infection was 14.8% and 18.0% respectively. Conclusion The dominate pathogen which caused the central venous catheterization associated infection are staphylococcus and fungus. Strict catheter nursing and shorten indwelling time are the effective methods to prevent infection.
