Insights

Pediatric hemodialysis catheters are crucial for vascular access, but infection remains a major complication. Uncuffed catheters suit short-term use, while cuffed catheters offer longer-term solutions.

Area of Science:

  • Pediatric Nephrology
  • Vascular Access Management
  • Infectious Disease

Background:

  • Hemodialysis catheters are vital for dialysis, especially in children requiring lifelong access.
  • Repeated vascular access in pediatric patients can lead to significant morbidity and mortality.

Purpose of the Study:

  • To evaluate the efficacy and complications of different hemodialysis catheter types in pediatric patients.
  • To analyze factors influencing catheter dwell time and removal causes.

Main Methods:

  • Retrospective study of all hemodialysis catheters inserted over 40 months at a pediatric center.
  • Data collected included patient demographics, catheter type, insertion details, dwell duration, and reasons for removal.

Main Results:

  • 195 uncuffed catheters used in 131 patients (mean dwell 35.7 days); 87.4% successful access, 35.1% removed due to complications (mainly infection).
  • Catheter-related bacteremia rate was 9.6 episodes/1,000 catheter days, increasing with dwell time.
  • 19 cuffed tunneled catheters used (mean dwell 117 days), primarily removed due to infection or thrombosis.

Conclusions:

  • Uncuffed central venous catheters are effective for short-term pediatric hemodialysis.
  • Cuffed tunneled catheters can provide vascular access for extended durations.
  • Infection is a primary concern for both catheter types, necessitating careful management.

Hemodialysis I: Introduction01:25

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...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

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 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,...

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...
Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

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...

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 critically...
