NEJM:低温治疗用于改善不可电击复律患者的神经功能结局

2019-12-12 MedSci MedSci原创

研究认为,在心脏骤停、非可电击心律复苏的昏迷患者中,接受33°C下持续24小时的中度治疗性低温可获得更好的神经功能预后

目前建议采用中度治疗性低温治疗以改善院外心脏骤停复苏后持续性昏迷患者的神经结局。然而,对于不可电击复律患者(心脏停搏或无脉搏电活动),中度治疗性低体温的有效性仍存在争议。

研究人员进行了一项开放性、随机、对照试验,心脏骤停和非可电击心律复苏后被送入重症监护病房(ICU)患者参与,随机进行中度治疗性低温(前24小时为33°C)与靶向常温(37°C)的疗效。研究的主要结局为具有良好神经系统结局的生存,以第90天通过大脑功能类别(CPC)量表进行评估(范围从1到5,分数越高,显示更大的残疾)。神经学结果良好定义为CPC评分为1或2。

581名患者参与研究。在第90天,低温组284例患者中有29例(10.2%)存活,且CPC评分为1或2分,而常温组297例中有17例(5.7%)存活且神经学结果良好(差异4.5%)。低温组与常温组90天死亡率无显著性差异(分别为81.3%和83.2%,差异,-1.9%)。预先指定的不良事件的发生率在各组之间没有显著差异。

研究认为,在心脏骤停、非可电击心律复苏的昏迷患者中,接受33°C下持续24小时的中度治疗性低温可获得更好的神经功能预后。
