概括
远端辐射接入 (DRA) 是冠状动脉手术的一种安全有效的技术. 动脉脉强度,超声指导和操作员经验是成功DRA的关键因素,最大限度地减少并发症.
科学领域:
- 心脏病学 心脏病学
- 血管接入 血管接入
- 干预程序 干预程序
背景情况:
- 远距离辐射接入 (DRA) 对冠状动脉手术的传统跨辐射接入具有优势,包括减少血管并发症和改善患者舒适度.
- 预测DRA失败的预测因素需要进一步定义以优化其临床应用.
- 这项研究评估了在广泛的患者群体中DRA失败的可行性,安全性和预测因素.
研究的目的:
- 评估远距离辐射接入 (DRA) 的可行性和安全性,在接受冠状动脉手术的全新人群中.
- 确定DRA失败和成功的独立预测因素.
- 制定一个基于证据的战略,以优化DRA程序的结果.
主要方法:
- 一项前性多中心队列研究包括1387名患者,其中1454名患者通过DRA接受了冠状动脉手术.
- 用多变量逻辑回归和条件推理树 (CIT) 来确定失败的预测因素.
- 数据是在2020年8月至2024年9月期间收集的.
主要成果:
- DRA的成功率很高 (96.5%),99%的手术成功完成.
- 与接入相关的并发症很低 (2.5%),包括0.8%的在医院的辐射动脉封闭.
- 较弱的远端辐射脉冲是失败的最强预测因素 (OR: 10.07),而手术前超声波 (US) 评估,US引导穿刺,右侧接入和操作员经验预测了成功. 美国指南显著改善了弱脉冲患者的治疗结果 (98.2% vs 61.0%).
结论:
- 远距离辐射接入 (DRA) 是冠状动脉手术的安全,可行的和有效的策略.
- 手术成功受到动脉脉冲强度,超声指导和操作员经验的显著影响.
- 一个CIT衍生框架提供了一个实用的方法来优化访问站点的选择和提高程序的结果.

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.

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:
