心脏介入治疗院内感染的调查分析

Analysis of noscomial infection after cardiac intervention therapy

目的：对我科心脏介入治疗后的院内感染发生率及易感因素进行回顾性调查分析，并探讨其防治措施。 方法： 我科自１９７３～１９９９年６ 月共收治行心脏介入治疗患者１ １００ 例，按照年龄、性别、手术种类、院内感染发生率及感染部位等资料进行比较分析。 结果：１ １００ 例患者中，术后感染２７例，感染率为２．４５％ 。包括经皮二尖瓣球囊成形术（ＰＢＭＶ）３８０ 例，感染２１ 例，感染率为５．５３％ ；永久性心脏起搏器安置术５２０ 例，感染６ 例，感染率为１．１５％ ；射频消融术２００ 例，无感染发生。最常见的感染为血管相关性感染和切口感染。感染发生与性别无显著相关性。 结论： 心脏介入治疗后院内感染发生率较低，通过严格的无菌操作和抗生素的合理应用，可防止院内感染的发生。

Objectives: To investigate and analyze the nosocomial infection rates(NIR) and risk factors of cardiac intervention therapy,and discuss the effective preventive measures. Methods:The data of 1100 patients were compared by age、sex、operational kinds,NIR and infectious place. Results:The total NIR was 2.45%,NIR in percutaneous mital balloon valvuloplasty and long term cardiac pacing were 5.53% and 1.15% respectively,the patients with radiofrequency ablation were not infected. The common infective places were vascular related infection and wound infection. The infection were not related with gender. Conclusions: The NIR of cardiac intervention therapy was low,and the NIR could be redused by the severely aspetic operation and rational antibiotic application.
