概括

增强血压管理并没有改善脊髓损伤患者的神经恢复. 这项研究表明,传统的血压目标可能更安全,质疑早期增强血压策略的好处.

科学领域:

神经学神经学
创伤护理创伤护理
关键护理医学关键护理医学

背景情况:

早期的血压管理对于脊髓损伤 (SCI) 神经复苏至关重要.
最佳的血压目标 (增高或常规) 仍然不清楚.

研究的目的:

在急性SCI患者的6个月神经学结果上,比较增强血压管理与常规血压管理的疗效和安全性.

主要方法:

一个多中心随机临床试验,涉及92名成人SCI患者.
患者随机分配,维持增高 (>85-90毫米升) 或常规 (>65-70毫米升) 平均动脉压7天或直到ICU出院.
主要终点包括运动和感官变化,美国脊柱损伤协会6个月损伤量表得分. 安全终点包括器官功能障碍和并发症.

主要成果:

在6个月后,在增强和常规血压组之间没有观察到运动或感觉得分恢复的显著差异.
增强组经历了更高的器官功能障碍率 (修改了序列器官衰竭评估得分),更长的机械通风和更多的呼吸道并发症.
没有发现死亡率或其他次要结果的差异.

结论:

这项功能不足的试验没有证明SCI患者早期增高血压的神经恢复有所改善.
这些发现质疑常规使用增强血压,并暗示潜在的危害,需要进一步研究.
未来的研究应该确定可能从增加血压中受益的患者子组,并阐明危害机制.
