Dialysis

1.7K
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...

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 I: Introduction

2.5K
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...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Hemodialysis III: Nursing Management

1.2K
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...

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,...

Area of Science:

  • Nephrology
  • Healthcare Quality Improvement
  • Water Treatment Technologies

Background:

  • Hemodialysis (HD) and reverse osmosis (RO) machine water quality is critical and must meet American Association of Medical Instrumentation standards.
  • A root cause analysis (RCA) was employed to identify and resolve water quality issues in HD and portable RO machines.

Purpose of the Study:

  • To identify and address factors affecting water quality in hemodialysis and reverse osmosis machines.
  • To implement interventions that ensure adherence to regulatory water quality standards.

Main Methods:

  • A multidisciplinary team utilized RCA, including process reviews and staff interviews.
  • Five interventions were implemented: three process-based (sampling technique, disinfection, maintenance duties) and two structural (tube cleaning, new sampling sites).

Main Results:

  • Post-intervention, 100% of water cultures from HD and RO machines met regulatory standards.
  • Consistent compliance was maintained over an 8-month period following protocol implementation.

Conclusions:

  • The RCA approach effectively improved patient safety and quality of care in the HD program.
  • Streamlined processes and enhanced work efficiencies for HD staff were achieved.
