概括
与HeartMate II不同的是,HeartMate 3设备显著提高了电肌谱指数 (EMG) 的读数. 麻醉科医生应该在解释患者的EMG时考虑这个工件 HeartMate 3 准确监测.
科学领域:
- 心脏病学 心脏病学
- 麻醉学 麻醉学
- 生物医学工程 生物医学工程
背景情况:
- 脑电图 (EEG) 衍生显示器可能会受到人造物质的影响.
- 该HeartMate 3心室辅助器件的频率与用于电肌学指数 (EMG) 和双光谱指数 (BIS) 计算的频率重叠.
- 像HeartMate II这样的先前设备没有显示这种干扰.
研究的目的:
- 为了调查HeartMate 3设备是否会导致EMG和BIS值的升高,与植入前水平相比.
- 将HeartMate 3对EMG和BIS的影响与HeartMate II的影响进行比较.
主要方法:
- 一项回顾性观察性研究分析了接受HeartMate 3或HeartMate II植入器的患者的数据.
- 在LVAD前 (手术开始至心肺旁路) 和LVAD后 (心肺旁路结束至手术结束) 期间,比较了EMG和BIS值的中位数.
- 分析了33名HeartMate 3和43名HeartMate II患者的数据.
主要成果:
- 患有HeartMate 3的患者显示EMG显著升高 (LVAD前26.1±1.0dB至LVAD后39.5±2.8dB,P<0.001).
- 在HeartMate 3患者中没有观察到BIS的显著变化 (44.5 ± 8.1前LVAD到45.5 ± 7.1后LVAD,P = 0.35).
- 对于HeartMate II患者,EMG和BIS都没有显著变化.
结论:
- 植入HeartMate 3显著提高了EMG值.
- 麻醉科医生必须意识到这一EMG人工物,以确保HeartMate 3患者的准确解释.
- 这些发现强调了理解神经监测中特定设备干扰的重要性.

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Direct Method
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...
