在心脏手术期间,非侵入性连续血红蛋白 (SpHb) 测量在手指之间有所不同. 从三根指尖平均SpHb提高了实验室血红蛋白 (Lab-Hb) 估计的准确性和精度.
科学领域:
- 心血管外科心血管外科
- 医疗器械 医疗器械
- 临床监测 临床监测
背景情况:
- 在心脏外科手术中,非侵入性持续血红蛋白监测 (SpHb) 是至关重要的.
- SpHb读数的变化可能会影响临床决策.
- 了解传感器位置的影响对于准确的监控至关重要.
研究的目的:
- 用不同的指尖上的传感器来调查SpHb测量的差异.
- 为了评估与单个传感器读数相比,平均 SpHb 的准确性和精度.
- 评估在选择性心脏手术期间传感器部位对SpHb测量的影响.
主要方法:
- 一项前性观察性临床研究,涉及12名接受选择性冠状动脉旁路移植 (CABG) 的成年患者.
- 三个相同的SpHb传感器被放置在同一个手的指尖上,连接到Masimo Radical-7显示器.
- 统计分析包括Kruskal-Wallis,Alexander-Govern测试,Bland-Altman图表和Giavarina图表,将SpHb与侵入性Lab-Hb进行比较.
主要成果:
- 从三个传感器的时间匹配的SpHb数据之间观察到良好的相关性 (r=0.86-0.95).
- 在单个传感器SpHb值和平均SpHb值之间发现了显著的差异 (p<0.05).
- 与单个传感器相比,平均SpHb在估计Lab-Hb的准确性和精度更高.
结论:
- 传感器放置位置显著影响SpHb测量,导致差异.
- 从三根手指尖平均SpHb读数可以提高Lab-Hb估计的准确性和精度.

The Brachial Artery: Primary Site for Blood Pressure Measurement
Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
