概括

在患有全身性硬化症 (SSc) 的患者中,大脚是最冷的,手指和脚的温度是相关的. 在SSc的寒冷四肢需要足科的评估和足部护理教育.

科学领域:

类风湿病学类风湿病学
皮肤病学皮肤病学
血管医学血管医学

背景情况:

系统性硬化症 (SSc) 与雷诺现象 (RP) 相关,导致数字缺血症.
评估SSc患者的外周循环对于管理数字等并发症至关重要.

研究的目的:

在SSc患者中测试脚是否比健康对照更冷.
为了确定大脚是否表现出最显著的温度下降.
为了研究手和脚的温度学异常之间的相关性.

主要方法:

手和脚的热像图像是用与iPhone相连的热摄像头拍摄的.
在40名SSc患者和20名对照患者的手指和脚中测量了远端背部差异 (DDD).
分析了手指和脚的温度梯度之间的相关性.

主要成果:

一个趋势表明,与对照组相比,SSc患者的大脚较冷 (平均DDD:-2.90°C与-2.39°C).
在SSc患者中,大脚比其他脚更冷,虽然不是显著的.
在SSc患者的手指和大脚的温度梯度之间发现了显著的相关性 (r=0.406, ρ=0.01).

结论:

大脚是SSc患者最冷的四肢.
在SSc患者中,冷手指与冷脚有关,这表明有系统性血管问题.
移动温度计是数字血管评估的可行工具,需要进一步验证.

Assessment of the Cardiovascular System III: Palpation

Assessment of the Cardiovascular System III: Palpation

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...
