Insights

Chronic hemodialysis (HD) is a viable option for infants under 10 kg when peritoneal dialysis fails. Careful vascular access management minimizes complications, ensuring successful long-term treatment for pediatric patients.

Area of Science:

  • Pediatric Nephrology
  • Renal Replacement Therapy
  • Infant Health

Background:

  • Hemodialysis (HD) is typically a second-line treatment for infants when peritoneal dialysis (PD) is unsuccessful.
  • This study examines the use of HD in infants weighing less than 10 kg.

Purpose of the Study:

  • To evaluate the morbidity, complications, and outcomes of long-term HD in infants weighing less than 10 kg.
  • To assess the viability of HD as a management option for this specific pediatric population.

Main Methods:

  • A retrospective review of clinical data for infants under 10 kg undergoing HD for over 6 months was performed.
  • Data collected included demographics, anthropometrics, diet, vascular access details, HD prescription, complications, and outcomes.

Main Results:

  • Nine infants meeting the criteria were analyzed, with a median age of 9 months at HD initiation.
  • Growth parameters showed improvement during HD, with median energy and protein intake of 96.6 kcal/kg/day and 1.66 g/kg/day, respectively.
  • Vascular access demonstrated good longevity (median 13 months for central venous catheters) and low infection rates (0.14/patient year), with a median of 0.32 line changes/patient year.

Conclusions:

  • Chronic HD is a feasible treatment for infants weighing less than 10 kg.
  • Effective vascular access care is crucial for maximizing catheter longevity and minimizing infection rates in this cohort.

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...

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...
Dialysis01:27

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...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...
