概括
在Impella 5.5患者中,高血解与较长时间使用设备,更多的机械循环支持 (MCS) 和增加的输血有关. 这种情况表明这个高危人群的预后不好.
科学领域:
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
背景情况:
- 血液溶解是机械循环支持 (MCS) 的并发症,在皮肤穿左心室辅助器件中没有得到充分的研究.
- 这项研究描述了由Impella 5.5设备支持的患者的血液溶解后续.
研究的目的:
- 为了研究与Impella 5.5支持患者的血液溶解相关的因素.
- 为了确定这个患者队列中血液溶解的预后影响.
主要方法:
- 从2020年到2023年,对169名Impella 5.5患者进行了回顾性审查.
- 根据血自由血红蛋白 (PfHb) 水平,分类为高溶血 (HH) 和低溶血 (LH) 组.
- 分析与血液溶解相关的临床因素和结果.
主要成果:
- 高血解 (HH) 患者的入院SCAI阶段更高,更多的Impella5.5天,需要更多的额外MCS和血液产品输血.
- 额外的MCS和增加的Impella日被确定为血液溶解的危险因素.
- 在HH组 (73%) 的死亡率高于LH组 (44%).
结论:
- 在Impella 5.5支持的患者中,血液溶解,特别是在这种高风险队列中,与预后不佳有关.
- 患有高血解症的患者需要更多的设备日,额外的MCS和输血.

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration
377
Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Hemodialysis II: Procedure and Complications
2.2K
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,...
