Insights

Bundle branch block (BBB) affects 11.4% of patients starting dialysis, a higher prevalence than in the general population. Older age and obesity are linked to BBB, with left BBB indicating a poorer prognosis.

Area of Science:

  • Cardiology
  • Nephrology
  • Epidemiology

Context:

  • Bundle branch block (BBB) is a common cardiac finding, but its prevalence in dialysis patients is largely unknown.
  • Understanding BBB prevalence and associated factors in this high-risk population is crucial for cardiovascular risk assessment.

Purpose:

  • To determine the prevalence of complete bundle branch block (BBB) in patients initiating dialysis.
  • To identify clinical, biochemical, and echocardiographic factors associated with BBB in this cohort.
  • To explore the association of BBB with mortality and cardiovascular events in patients starting dialysis.

Summary:

  • A study of 211 patients starting dialysis found a BBB prevalence of 11.4% (6.0% left BBB, 8.5% right BBB).
  • Independent predictors of BBB included older age (OR=1.05) and higher body mass index (OR=1.12).
  • Over a mean follow-up of 23.7 months, left BBB showed a trend towards poorer outcomes.

Impact:

  • The prevalence of BBB is significantly higher in patients starting dialysis compared to the general population.
  • Older age and obesity are key factors associated with BBB in dialysis patients.
  • Left BBB may serve as an indicator of poor prognosis in patients initiating renal replacement therapy.

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 measurement...

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...
Dialysis01:15

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

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,...

Chronic Kidney Disease I: Introduction

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...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...
