概括
与温水相比,二氧化碳 (CO2) 手浴显著改善了系统性硬化症 (SSc) 相关的雷诺现象 (RP) 患者的微血管功能. 二氧化碳浴提供了一个安全的,非药物治疗SSc-RP的选择.
科学领域:
- 血管生物学 血管生物学
- 类风湿病学 类风湿病学
- 皮肤病学 皮肤病学
背景情况:
- 雷诺现象 (RP) 是系统性硬化症 (SSc) 患者的常见和衰弱的并发症.
- 在SSc患者中,RP显著损害了微血管功能和生活质量.
- 目前用于SSc-RP的治疗方法通常具有有限的疗效或显著的副作用.
研究的目的:
- 为了评估二氧化碳 (CO2) 与温水手洗手的直接,细分体特定的微血管效应,在SSc患者中进行二次RP.
- 为了比较SSc患者和健康对照人群之间的血管扩张反应.
- 评估干预后微血管变化的持久性.
主要方法:
- 一个单中心,随机对照试验,涉及24名SSc患者和12名健康对照.
- 随机分配的SSc患者接受了15分钟的CO2浴 (2g/L,35°C) 或热水浴 (40-42°C).
- 用指甲毛细管镜测量了脉管 (VA),顶部和脉管 (VE) 的直径,在基线,干预后立即和干预后10分钟.
主要成果:
- 在SSc患者中,CO2浴室导致VA (3.31μm) 和VE (3.83μm) 的平均直径显著增加,超过了温水浴室观察到的变化.
- 在健康对照组中,CO2诱导了血管扩张,但VA直径的增加不如SSc患者那么明显.
- 在干预后10分钟,VA直径在二氧化碳组相比热水组仍然显著更高,表明持续的影响.
结论:
- 与温水相比,单次二氧化碳手洗在SSc相关的RP中促进了更大,更持续的指甲毛细血管扩张.
- 对热水的反应受损表明SSc中缺陷的热诱导血管扩张,而CO2可能会激活替代的血管扩张途径.
- 二氧化碳手浴是SSc-RP的安全,经济有效和非药物辅助疗法,需要在更大的临床试验中进一步调查.

01:27Assessment of the Cardiovascular System III: Palpation
1.2K
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...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
491
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
