概括
在心脏性休克中植入Impella 5.5®的关动脉 (AX) 接入显示出类似的安全性和结果,无论AX直径或插入侧面如何. 这项研究表明,对于Impella 5.5®程序的AX访问选择,可以灵活进行.
科学领域:
- 心血管医学 心血管医学
- 干预心脏病学 干预心脏病学
- 医疗器械 医疗器械
背景情况:
- 恩佩拉5.5®经常用于心脏性休克,通常通过关动脉 (AX) 进入.
- 传统实践倾向于右侧的AX以避免大动脉门穿越,对于21 Fr装置,建议的最小直径为7 mm.
- 关于AX横向性和大小对Impella 5.5®手术成功和患者结果的影响的数据有限.
研究的目的:
- 评估关动脉接入侧面 (右与左) 和直径 (小<7毫米与正常≥7毫米) 对Impella 5.5®植入结果的影响.
- 评估与不同的 AX 访问策略相关的技术成功,交付时间和不良事件率.
- 为了确定AX访问特征是否会影响患者存活到出院的时间.
主要方法:
- 75名接受Impella 5.5®植入的患者的单中心回顾性队列分析 (2020年12月 - 2024年2月).
- 数据按AX直径 (<7毫米对≥7毫米) 和横向 (右对左) 分层.
- 分析了不良事件 (中风,四肢缺血,出血,感染) 和分娩时间.
主要成果:
- 通过AX方法,技术成功率为95.9% (71/74次尝试).
- 10名患者 (13.5%) 的AX小 (<7毫米),与正常AX相比,分娩时间或不良事件没有显著差异.
- 根据AX大小或横向性,没有观察到中风,缺血,出血或感染率的显著差异.
结论:
- 关动脉的横向性和较小的直径 (<7毫米) 不会对Impella 5.5®的植入结果或安全概况产生不利影响.
- 这些发现支持在选择Impella 5.5®程序的AX访问时提供更大的灵活性.
- 出院后的存活率为59.5%,死亡率仅发生在正常AX直径的患者中,无论横向性如何.

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:21Sites for measruring blood pressure
1.5K
Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
