概括
氨基酸补充剂显著降低了主动脉手术患者急性损伤 (AKI) 的发生率. 在一项随机对照试验中观察到这种预防作用,这表明了术后脏保护的潜在新疗法策略.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 心血管外科心血管外科
- 营养科学 营养科学
背景情况:
- 手术后急性损伤 (AKI) 是大手术后的严重并发症,特别是心肺旁路术的大动脉手术.
- 氨基酸在细胞代谢和功能中起着至关重要的作用,这表明在预防AKI方面可能发挥作用.
研究的目的:
- 研究氨基酸补充剂在降低大动脉手术患者AKI发病率方面的预防效果.
- 评估外科手术期间氨基酸给药对结局的影响.
主要方法:
- 进行了一项单中心,患者和评估者盲目的随机对照试验.
- 接受大动脉外科手术并进行心肺旁路术的患者随机分配,接受每天60g的氨基酸长达3天或标准护理.
- 主要结果是AKI的发病率,使用Cox比例危险回归来评估.
主要成果:
- 66名患者被随机分配;33人接受了氨基酸,32人接受了标准护理.
- 与对照组 (56.2%) 相比,在氨基酸组 (30.3%) 中,AKI的发生率明显较低.
- 对AKI的调整后危险比为0.44 (95%CI,0.20-0.95;P=0.04),表明具有保护作用.
结论:
- 在外科手术期间服用氨基酸补充剂,在接受大动脉手术的患者中,急性损伤的发生率显著降低.
- 这一发现表明,氨基酸可以作为一种可行的预防策略来预防术后的AKI.

424
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

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...
