概括

动脉静脉 (AVF) 成熟失败很常见,超过20%的人还没有准备好进行管. 风险因素包括外围动脉疾病和中枢前静脉 (MACV) 抽的使用,而放射性脑前风 (RCAVF) 在选择的患者中显示出更好的结果.

科学领域:

血管外科血管外科
腎臟病學 (nephrology) 是一種醫學.
透析服务透析服务透析服务

背景情况:

动脉静脉 (AVF) 成熟失败导致患者风险增加和资源利用.
识别可修改的囊未成熟 (FTM) 风险因素对于改善结果至关重要.

研究的目的:

为了确定与AVF未成熟 (FTM) 到管准备相关的患者和手术因素.
探索改善AVF成熟率的潜在策略.

主要方法:

从2015年到2021年进行初级AVF创建的363名患者的回顾性审查.
对人口统计学,并发病,形状 (包括中枢前静脉[MACV]和放射性脑[RCAVF]) 和后续程序的分析.
单变量和多变量分析,以在1年内确定与FTM相关的因素.

主要成果:

超过23%的AVF没有成功成熟.
周围动脉疾病,1年内死亡和MACV丸使用与FTM有显著的关联.
放射性AVF (RCAVF) 与FTM无关,女性和老年患者接受RCAVF的可能性较小.
气球辅助成熟 (BAM) 在60%的病例中是成功的,但在多变量分析中矛盾地与不成熟有关.

结论:

超过五分之一的AVF无法达到通管准备,突出需要改进患者和程序选择.
避免MACV囊,并考虑在1年内死亡高风险的患者中构建AVF,可能会提高成熟率.
可以预计RCAVF在精心挑选的患者中会成熟,而BAM应考虑在未成熟的囊中.

Hemodialysis I: Introduction

Hemodialysis I: Introduction

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...

Hemodialysis III: Nursing Management

Hemodialysis III: Nursing Management

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 II: Procedure and Complications

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,...

Dialysis

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...

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...

Peritoneal Dialysis III: Nursing Management

Peritoneal Dialysis III: Nursing Management

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
