概括
与每周两次的高血压透析 (HD) 相比,每周一次的低蛋白饮食和类药物透析更好地保留了新的HD患者的残留功能 (RKF). 这种方法保持了营养和代谢安全.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 脏替代疗法治疗 脏替代疗法
- 临床营养学 临床营养学
背景情况:
- 剩余功能 (RKF) 的快速丧失与末期病 (ESKD) 的不良结果有关.
- 增量血液透析 (HD) 策略旨在保护RKF.
研究的目的:
- 为了比较每周一次的HD (1-WHD) 与每周两次的HD (2-WHD) 在保持RKF方面的疗效.
- 评估不同饮食方案对RKF和营养状况的影响.
主要方法:
- 一项随机对照试验 (RCT) 涉及30名发病的HD患者,其EGFR为5-10毫升/分钟/1.73平方米,尿量≥800毫升/天.
- 患者被分配为1-WHD与低蛋白饮食 (0.6克/千克/天) 加上类药物 (KAs) 或2-WHD与常规蛋白质饮食12个月.
- 主要结局包括清和尿量变化;次要结局评估了营养状况,肌肉参数和生活质量 (QoL).
主要成果:
- 在整个研究中,1-WHD组的尿量显着更高 (p=0.02在3个月).
- 1-WHD显示尿尿 (CUrea) 和肌素清除 (CCr) 的下降较小,从第6个月观察到显著差异 (例如,CUrea:3.2±2.3与1.7±1.0毫升/分钟,p=0.03).
- 营养标志物,肌肉质量,贫血,代谢参数,尿素毒素和QOL在两组之间是可比的.
结论:
- 与每周两次的HD相比,每周一次的HD与蛋白质限制和KA相结合,有效地保留了RKF在事件的HD患者中,而不是每周两次的HD.
- 这种增量性HD疗法是安全的,保持了可比的代谢和营养特征.

Acute Kidney Injury V: Interprofessional Care
44
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...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Dialysis
478
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...

Hemodialysis III: Nursing Management
187
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Hemodialysis I: Introduction
290
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Chronic Kidney Disease I: Introduction
67
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...
