JAMA:减少加压素暴露不能降低老年血管扩张性低血压危重患者的90天死亡率

对于伴有血管舒张性低血压的老年ICU患者,减少血管升压药物治疗不能减少患者死亡风险

ICU患者常使用血管升压类药物以提高血压,但对老年患者而言平衡血管升压类药物的风险和益处是一个严峻的挑战。近日研究人员考察了对于平均动脉压(MAP)60-65mmHg的患者,减少使用血管升压类药物对伴有血管舒张性低血压ICU患者90天死亡率的影响。

研究在英国65个ICU中心开展,2600名65岁及以上伴有血管舒张性低血压患者参与,随机接受MAP60-65mm Hg护理(允许性低血压组,n=1291)或常规护理(n=1307)。研究的主要临床结果为90天全因死亡率。

2463(95%)名患者数据纳入主要结果分析(平均年龄75岁,1387名[57%]男性)。允许性低血压组的患者与常规护理组相比,血管升压类药物的使用程度较低(药物中位持续时间33小时 vs 38小时;中位数差异:-5.0小时;去甲肾上腺素等价物的总剂量中位数:17.7 mg vs 26.4 mg;中位数差异:-8.7 mg)。在90天时,允许性低血压组1221人中有500人死亡(41.0%),而常规护理组1242人中有544人死亡(43.8%,绝对风险差为-2.85%,未经调整的相对风险为0.93)。调整预先指定的基线变量时,90天死亡率的比值比为0.82。组间不良事件率相当,最常见的严重不良事件是急性肾功能衰竭和室上性心律失常。

研究认为,对于伴有血管舒张性低血压的老年ICU患者,减少血管升压药物治疗不能减少患者死亡风险。
