- 腎臟病學 (nephrology) 是一種醫學.
- 麻醉学 麻醉学
背景情况:
- 急性损伤 (AKI) 是使用心肺旁路 (CPB) 的心脏手术后的常见并发症.
- 晶体原始化溶液可能通过血液溶解和流体转移导致AKI.
- 之前的研究表明,基于德克斯的溶液对脏有潜在的益处.
研究的目的:
- 测试基于德克斯的CPB原始溶液是否能降低高风险心脏手术患者的术后AKI.
- 评估德克斯原始化对外科手术期间血液溶解,液体平衡和置换疗法的影响.
主要方法:
- 一个随机的,受控的,双盲的,多中心的试验,比较德克斯与晶体化CPB原始化溶液.
- 包括成年患者,其计算后术AKI风险≥50%.
- 主要结局:术后96小时内AKI发生率;次要结局:血液溶解,液体平衡,置换疗法.
主要成果:
- 由于招生速度缓慢 (分析了92名患者),该试验被提前终止.
- 在手术后的AKI发生在81%的德克斯组和53%的对照组 (RR 1.53,p=0.004).
- 德克斯组显示手术内血液溶解减少和更好的液体平衡,但脏替代疗法没有显著差异.

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

01:22Acute Kidney Injury I: Introduction
562
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

01:30Continuous Renal Replacement Therapy
801
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
