NEJM:抗菌包膜预防心脏植入装置感染

2019-05-16 xing.T 网络

与单独的标准治疗感染预防策略相比,辅助使用抗菌包膜导致主要CIED感染的发生率显著降低,而并发症发生率没有增加。

放置心脏可植入电子设备(CIEDs)后的感染与大量的发病率和死亡率相关。除了术前使用抗生素外,预防性策略的证据十分有限,无法预防此类感染

近日,顶级医学期刊NEJM上发表了一篇研究文章,研究人员进行了一项随机对照临床试验,以评估可吸收的抗生素洗脱包膜在降低CIED植入相关感染发生率方面的安全性和有效性。正在进行CIED口袋修正、发生器更换或系统升级或心脏再同步治疗除颤器的初始植入的患者以1:1的比例被随机分配接受或不接受抗生素洗脱包膜治疗。所有患者均使用标准护理策略来预防感染。主要终点是在CIED植入手术后12个月内感染导致系统提取或修复、长期抗生素治疗伴有感染复发或死亡。安全性的次要终点是12个月内与手术相关或系统相关的并发症。 

该研究共有6983名患者接受随机分组:3495例为包膜组,3488例为对照组。主要终点发生在包膜组有25例和对照组有42例(12个月Kaplan-Meier估计事件发生率分别为0.7%和1.2%;风险比为0.60; 95%置信区间[CI]为0.36至0.98; P=0.04)。安全性终点发生在201例患者中,对照组为236例(12个月Kaplan-Meier估计事件发生率分别为6.0%和6.9%;风险比为0.87; 95%CI为0.72~1.06);非劣效性P<0.001)。随访的平均(±SD)持续时间为20.7±8.5个月。在整个随访期间发生的主要CIED相关感染发生在包膜组的32名患者和对照组的51名患者中(风险比为0.63; 95%CI为0.40至0.98)。

与单独的标准治疗感染预防策略相比,辅助使用抗菌包膜导致主要CIED感染的发生率显著降低,而并发症发生率没有增加。
