在一项多中心随机试验中,德国学者将急性肾损伤高风险患者纳入研究对象。来自4家医院的240例患者,被随机分配到远程缺血预处理组或对照组;结果发现,远程缺血预处理减少了心脏手术高危患者的急性肾损伤。本文中,作者又报告了远程缺血预处理对90 d结局的影响。在这项肾脏RIP试验的随访研究中,作者观察了远程缺血预处理(标准血压测量袖带上臂充气加压5 min再放气共4次) In a multicenter randomized trial, German scholars included patients at high risk of acute kidney injury. 240 patients from four hospitals were randomly assigned to either a remote ischemic preconditioning group or a control group; it was found that remote ischemic preconditioning reduced acute kidney injury in high-risk cardiac surgery patients. In this article, the authors report the effect of remote ischemic preconditioning on 90-day outcomes. In a follow-up study of this renal RIP trial, the authors observed remote ischemic preconditioning (standard blood pressure cuff arm inflation and pressure for 5 min and then deflated 4 times)
