Summary
Nephrologists should offer dialysis only when beneficial, prioritizing patient well-being over automatic treatment. Shared decision-making is crucial for appropriate initiation and withdrawal from dialysis.
Area of Science:
- Nephrology
- Medical Ethics
Background:
- Nephrologists frequently encounter decisions regarding dialysis initiation and withdrawal.
- A common practice is offering dialysis for end-stage renal disease (ESRD) irrespective of risk-benefit analysis.
Purpose of the Study:
- To advocate for a treatment approach where nephrologists prescribe dialysis only when indicated and beneficial.
- To emphasize the ethical obligation to avoid treatments that offer more harm than benefit.
Main Methods:
- The study presents a position based on clinical judgment and ethical considerations.
- It references national guidelines on shared decision-making in renal replacement therapy.
Main Results:
- Dialysis should not be initiated if the patient is unlikely to benefit.
- Patients have the right to refuse treatment but cannot demand ineffective interventions.
Conclusions:
- Shared decision-making is the cornerstone for managing dialysis initiation and withdrawal.
- This approach aligns with the principle of providing beneficial and effective patient care.

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...

Dialysis
2.3K
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 III: Nursing Management
1.7K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
333
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Hemodialysis II: Procedure and Complications
2.0K
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,...

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis
1.0K
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...
