感染的心律植入装置再利用于同一个体的研究

Reuse of infected cardiovascular implantable electronic device in the same individual

目的探讨因感染取出的心律植入装置,经灭菌处理后再次应用于同一患者的安全性、可行性。方法选择因感染行装置移除术后,由于经济原因拒绝植入新装置的患者进行研究。通过对上述患者进行系统随访,以再次感染、装置故障相关事件为研究终点,评价感染装置再利用的安全性、可行性。结果在感染装置移除术后,59例患者植入了经灭菌处理过的原自身感染装置,其中1例患者(1.7%)出现再次感染,无装置故障相关事件发生。结论感染装置经灭菌处理后再利用于同一个体,是安全可行的。

Objective In this study, we evaluated the feasibility and safety of infected cardiac devices after sterilization treatment in the same individuals. Methods All patients with cardiac rhythm management device（CRMD） infection between 2007 and 2011 were entered into a computer database. From these, patients that had need for CRMD implantation and reimplantation of their infected device were analyzed for safety and complications. Results Fifty-nine patients underwent procedures for reimplantation of their infected device. Infection recurred in 1 patients（ 1. 7% ）. No early battery depletion or device malfunction was identified during follow-up. Conclusions Our data emphasize that reimplantation of explanted CRMDs, due to infection, within the same individual is feasible, safe, and effective.
