    Insights

    This study tracked calcium metabolism in 10 patients undergoing hemodialysis using 47-Ca. Results show a significant reduction in calcium metabolism during dialysis, indicating calcium inflow through the dialyzer.

    Area of Science:

    • Biochemistry
    • Nephrology
    • Radiochemistry

    Context:

    • Investigates calcium metabolism in patients with chronic kidney disease undergoing hemodialysis.
    • Utilizes the radioisotope 47-Ca for precise metabolic rate measurements.
    • Focuses on stabilized patients within a chronic dialysis program.

    Purpose:

    • To quantify the changes in calcium metabolism before and during hemodialysis.
    • To determine the rate of calcium transfer across the dialyzer membrane.
    • To understand the impact of hemodialysis on calcium homeostasis.

    Summary:

    • Calcium metabolism was assessed in 10 hemodialysis patients using 47-Ca.
    • The metabolic rate decreased from 0.395 h-1 to 0.208 h-1 during dialysis.
    • This reduction (0.43 mmol L-1 h-1) is attributed to calcium inflow via the dialyzer.

    Impact:

    • Provides insights into calcium kinetics during hemodialysis.
    • Highlights the dialyzer as a significant route for calcium exchange.
    • Informs strategies for managing mineral and bone disorders in dialysis patients.

    Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

    Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

    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,...

    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...

    Carbohydrate Metabolism

    Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
    Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
