- 紧急医疗 紧急医疗
- 医疗技术 医疗技术 医学技术
背景情况:
- 对于大血管封闭 (LVOs) 的医院前中风查缺乏跨机构的标准化.
- 现有的手动冲击秤可能会耗时,并且在应用上有所不同.
- 最终中风量表 (USS) 软件自动化多个中风查量表,以提高效率和预测价值.
研究的目的:
- 为了比较手动冲击量表计算与使用终极冲击量表 (USS) 的电子计算得分.
- 通过评估其协议和诊断准确性与已建立的中风尺度对比,通过外部验证USS软件.
- 评估USS在简化LVO医院前中风查方面的潜力.
主要方法:
- 八个中风查尺度 (NIHSS,BE-FAST,VANE,LAMS,FAST-ED,EMS RACE,3-ISS,PASS) 应用于199次中风激活.这些中风查尺度包括:
- 从以前的研究中获得的手动尺度数据,使用USS软件进行了重新计算.
- 使用肯德尔的tt来评估一致性,使用ROC曲线来评估诊断准确性.
主要成果:
- 美国海军舰艇在所有尺度上都表现出与手动计算的强烈或中度一致 (肯德尔的 τ: 0.5490.931,所有 p < 0.001).
- PASS (τ=0.931),LAMS (τ=0.894) 和FAST-ED (τ=0.864) 显示了与USS的最高一致性.
- 在手动方法 (0.5900.743) 和USS (0.5750.758) 之间,诊断准确度 (AUC) 是可比的,FAST-ED显示了USS的最高AUC.

120
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

01:27Assessment of the Cardiovascular System III: Palpation
497
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
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...
