概括
人类白蛋白溶液 (HAS) 在治疗时预防低血压 (TA). 持续监测相对血量 (RBV) 有助于确定最佳的液体替代方案,特别是在使用普通盐水时.
科学领域:
- 肝脏病学
- 血液学
- 危急护理医学
背景情况:
- 需要使用人类白蛋白溶液 (HAS) 来预防低血压.
- 在血液透析过程中,CRIT- LINE监测器追踪相对血液体积 (RBV) 的变化,以减轻低血压事件.
研究的目的:
- 在治疗性血交换 (TPE) 和双过血化 (DFPP) 过程中评估RBV变化.
- 确定最佳的液体替代方案,以预防低血压.
主要方法:
- 一个回顾三名CIDP患者接受TA的病例系列.
- 使用CRIT-LINE监测器在TPE和DFPP期间评估RBV,使用不同的液体替换策略.
- TPE协议的比较:100%的白蛋白,70%的白蛋白/30%的盐溶液 (早期) 和70%的白蛋白/30%的盐溶液 (晚期).
- DFPP方案的比较:持续的白蛋白输注和最后20分钟的白蛋白输注.
主要成果:
- TPE 协议显示RBV 值为-10%至-13% (TPE1),11%至-17% (TPE2) 和17%至-20% (TPE3).
- 使用TPE3 (最后阶段的盐水) 发生了低血压事件.
- 在DFPP协议中,RBV的最低值为-7%至-15% (DFPP1) 和-10%至-20% (DFPP2).
- 与晚期输注 (DFPP2) 相比,连续输注白蛋白 (DFPP1) 导致了较高的RBV最低值.
结论:
- 在TA期间持续监测RBV对于选择有效的替代液体方案至关重要.
- 涉及正常盐水的方案,特别是在TPE的后期阶段,与更大的RBV降低和低血压有关.
- 通过RBV监测优化液体替代策略可以提高TA过程中的患者安全.

141
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...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

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...

01:25Hemodialysis I: Introduction
287
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...
