概括
低度三酸盐 (TSC) 和未分离的肝素 (UFH) 是用于血液透析中心静脉导管 (CVC) 的有效导管锁定抗凝剂. 这两种药物都显示出相似的安全性和有效性,在特定的导管类型中可能减少TSC感染.
科学领域:
- 腎病學和泌尿病學.
- 传染性疾病 传染性疾病
- 药理学 药理学是指药理学的学科.
背景情况:
- 中枢静脉导管 (CVCs) 对于血液透析至关重要,当囊或移植物不可行时.
- 导管锁定抗凝剂 (CLA),包括三酸盐 (TSC) 和未分离肝素 (UFH),可以预防功能障碍,但对低度的比较数据有限.
研究的目的:
- 为了评估低度5%TSC与1000U/mLUFH作为CLA在血液透析CVC中的有效性和安全性.
- 为了比较导管功能障碍 (CD),血流感染 (CRBSI),出口部位感染 (ESI),出血和死亡率.
主要方法:
- 随机对照试验涉及204名血液透析患者,随机分配接受5%的TSC或1000U/mL的UFH作为CLA.
- 主要结局:180天后的导管功能障碍 (CD) 率.
- 二次结局:CRBSI,ESI,出血事件和死亡率.
主要成果:
- 在TSC (1.11/1000导管日) 和UFH (1.73/1000导管日) (IRR 1.55,p=0.23) 之间,CD发病率没有显著差异.
- 在两组之间观察到可比的CRBSI,ESI,出血和死亡率.
- 在道化袖带导管 (TCC) 中,ESI率在UFH中更高,尽管CD率保持相似.
结论:
- 5%的TSC和1000U/mL的UFH都是血液透析CVC的有效和安全的CLA.
- 在TCC小组中,在5%的TSC下,减少传染性并发症的潜在好处被注意到.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Hemodialysis II: Procedure and Complications
1.5K
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,...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
1.4K
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Hemodialysis I: Introduction
2.7K
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...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...
