概括
在患有急性损伤 (AKI) 或没有急性损伤 (AKI) 的重症COVID-19患者中,液体玻尿酸治疗没有改善 perfusion. 这项研究研究了这些患者的血膨胀对脏血流的影响.
科学领域:
- 关键护理医学 关键护理医学
- 腎臟病學 (nephrology) 是一種醫學.
- 心血管生理学心血管生理学
背景情况:
- 减少 perfusion 是急性损伤 (AKI) 的已知并发症在危急的COVID-19.
- 了解液体治疗对 perfusion 的影响对于管理这些患者至关重要.
研究的目的:
- 为了比较标准化液体玻尿酸对重症COVID-19患者的 perfusion 的影响,与那些没有AKI.
- 评估血扩张在改善脏血液流量的有效性,在这个患者群体.
主要方法:
- 采用了一种病例控制研究设计.
- 根据KDIGO标准,重症COVID-19患者被分为AKI和非AKI组.
- 使用磁共振成像 (MRI) 评估 perfusion 在 7.5 mL/kg Ringer's 乙酸盐注射之前和之后.
主要成果:
- 血扩张的血液动力学反应 (平均动脉压升高) 在两组中都相似.
- 在任何一组中,在液体给药后,全和皮层 perfusion 没有显著变化.
- 在没有AKI的患者中,观察到骨髓 perfusion 的显著减少.
结论:
- 标准化血扩张在重症COVID-19患者中没有增强 perfusion,无论AKI状态如何.
- 这些发现表明,在这种情况下,液体球体可能不是改善脏血流的有效策略.

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

01:17Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
