科学领域:
- 心脏病学 心脏病学
- 关键护理医学 关键护理医学
- 医疗干预 医疗干预
背景情况:
- 在心脏性休克 (CS) 患者体外膜氧化 (ECMO) 期间,左心室 (LV) 卸载至关重要,以减轻血液动力学损害.
- 一个关键的临床问题是,是否提前启动LV卸载或等待由于增加后负载而恶化的迹象.
研究的目的:
- 系统地审查和元分析早期与晚期左心室 (LV) 卸载在患有心脏性休克 (CS) 外体膜氧化 (ECMO) 的患者中的影响.
- 为了确定预防性LV卸载对死亡率,ECMO结果和临床康复的影响.
主要方法:
- 通过2023年12月发表的研究的系统审查和元分析,来源于PubMed,科学网络,SCOPUS和Cochrane.
- 使用风险比率 (RR) 的分类数据和使用平均差异 (MD) 的连续数据与使用R V的95%置信区间 (CI) 4.3.3.
主要成果:
- 分析了包括2,117名患者在内的8项研究.
- 早期/预防性LV卸载与所有原因死亡率显著降低有关 (RR:0.87;95% CI:0.79-0.95;p <0.01).
- 在心脏死亡率,非心脏死亡率,住院死亡率,ECMO断奶,心肌恢复,ECMO持续时间或早期和延迟卸载组之间的住院时间之间没有发现显著差异.
结论:
- 预防性左心室 (LV) 卸载在患有心脏性休克 (CS) 的患者体外膜氧化 (ECMO) 与所有原因死亡率和败血症/感染的发病率较低有关.
- 卸载LV的时间没有影响ECMO断奶率,心肌恢复,ECMO支持的持续时间或整体住院时间.

01:29Assessment of the Cardiovascular System II: Inspection
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.
