远距离和前臂辐射动脉压力显示出在脊柱手术全身麻醉期间监测血压的良好协议. 这些位置可以互换用于侵入性血压监测,在临床实践中提供灵活性.
科学领域:
- 麻醉学 麻醉学
- 心血管生理学心血管生理学
- 手术监测 手术监测
背景情况:
- 准确的侵入性血压 (IBP) 监测在一般麻醉 (GA) 时对于容易发生脊柱手术至关重要.
- 辐射动脉 (RA) 管道是标准的,但距离辐射动脉 (dRA) 接入可能具有优势.
研究的目的:
- 评估dRA和RA压力的一致性和可互换性.
- 评估两地IBP测量的趋势能力.
主要方法:
- 对40名接受GA脊柱手术的患者进行前性观察性研究.
- 同时调节右dRA和左前臂RA,以进行连续的IBP测量.
- 在关键的手术时间点上比较心压,心压和平均动脉压 (SAP,DAP,MAP).
主要成果:
- 在dRA和RA压力之间有很高的一致性,偏差最小,一致性极窄.
- 对于SAP (5.04%),DAP (5.10%) 和MAP (3.54%) 的低百分比错误.
- 在四个象限的地图中,一致率很高 (92-95%),表明可靠的趋势.
结论:
- 距离辐射动脉 (dRA) 和辐射动脉 (RA) 的压力显示出极好的一致性和趋势能力.
- 在GA期间的IBP监测中,dRA可以可靠地替代RA,用于易受脊髓手术的GA.

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:
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.
