JACC:围手术期增加抗生素治疗不会减少医疗设备相关感染

2018-12-18 MedSci MedSci原创

医疗植入设备相关的感染会造成严重的后果,对于心律失常设备的植入,预防性服用头孢唑林是一个标准的预防感染的手段,但不能预防耐甲氧西林革兰氏阳性微生物感染。本研究的目的旨在评估增加围手术期抗生素对减少设备相关性感染的临床效果。本研究进行了具有4个随机分配的6个月周期的分组随机交叉试验,对于所有植入性心脏电子设备的患者分成传统型抗生素预防治疗和围手术期增量抗生素预防治疗两组。传统型患者术前预防性服用头孢

医疗植入设备相关的感染会造成严重的后果,对于心律失常设备的植入,预防性服用头孢唑林是一个标准的预防感染的手段,但不能预防耐甲氧西林革兰氏阳性微生物感染。本研究的目的旨在评估增加围手术期抗生素对减少设备相关性感染的临床效果。

本研究进行了具有4个随机分配的6个月周期的分组随机交叉试验,对于所有植入性心脏电子设备的患者分成传统型抗生素预防治疗和围手术期增量抗生素预防治疗两组。传统型患者术前预防性服用头孢唑林,增量型患者术前预防性服用头孢唑林加万古霉素,术中杆菌肽袋洗,术后2天口服头孢氨苄。主要终点事件是术后医疗设备相关感染的1年住院率。最终共纳入来自28个医疗中心的19603名患者,传统型组有99名(1.03%)患者发生感染,增量型组有78名(0.78%)患者发生感染(OR:0.77; 95% cl: 0.56 - 1.05; p = 0.10),在高风险患者中,传统型组有77名患者因感染住院(1.23%),增量型组有66名(1.01%)患者因感染住院(OR:0.82; 95% cl: 0.59 - 1.15; p = 0.26)。

研究结果显示,对于植入心脏电子设备的患者,围手术期增加抗生素预防感染与不增加无统计学差异。

在既往心力衰竭的患者中,TSH≥7mIU/L的亚临床甲状腺功能减退症和单纯性低T3水平与预后不良有关。需要临床试验来探讨接受T4和T3治疗在心力衰竭中的治疗效果。
