与超吸附右径动脉 (HARRA) 方法相比,左径动脉 (LRA) 方法显著减少了干预心脏病学家的辐射暴露. 这一发现支持使用LRA用于诊断心脏导管,以尽量减少职业危险.
科学领域:
- 干预心脏病学 干预心脏病学
- 职业健康 职业健康 职业健康
- 辐射安全 辐射安全
背景情况:
- 干预性心脏病学家面临着重要的职业辐射暴露风险.
- 动脉接入部位的选择会影响心脏导管期间操作员的辐射剂量.
研究的目的:
- 为了比较使用左侧辐射动脉 (LRA) 与均超吸附右侧辐射动脉 (HARRA) 方法对操作人员的辐射暴露.
- 评估胸部,腹部和眼睛的累积和正常化辐射剂量.
主要方法:
- 单中心随机对照试验涉及534名患者.
- 操作人员被随机分配到用于诊断心脏导管治疗的LRA或HARA方法.
- 实时辐射剂量计测量了操作员胸部,腹部和眼睛的辐射.
主要成果:
- 与HARRA相比,LRA方法导致所有测量位置 (胸部,腹部,左眼,右眼) 的累积和正常化辐射暴露明显较低 (胸部和腹部P<0.001).
- 在LRA方法中,关节下形也较低 (15.6%与32.5%,P<0.001).
结论:
- 这种LRA方法与干预性心脏病学家的职业辐射暴露大幅减少有关.
- 建议增加LRA方法的使用,用于诊断心脏导管,以提高操作员的安全性.

Assessment of apical radial pulse
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.
Pre-Procedural Preparation
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:
Arteries of the Upper Limbs
Sites for measruring blood pressure
The Brachial Artery: Primary Site for Blood Pressure Measurement
Pre-Procedural Guidelines for Assessing Blood Pressure
Assessment of the Cardiovascular System III: Palpation
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
