Summary
Extracorporeal therapy, including hemodialysis, can remove toxins when kidneys fail. Treatment effectiveness depends on toxin properties, patient factors, and therapy specifics.
Area of Science:
- Nephrology
- Toxicology
- Critical Care Medicine
Background:
- Acute kidney injury (AKI) can impair the body's ability to clear ingested toxins.
- When native renal clearance is insufficient, extracorporeal removal methods are considered.
Observation:
- This review examines a case and literature on renal replacement therapy for acute intoxication.
- Extracorporporeal therapy efficacy is analyzed based on toxin characteristics, patient factors, and treatment parameters.
Findings:
- Toxin properties like molecular size, charge, and binding influence removal efficiency.
- Patient factors such as body habitus and volume of distribution affect treatment outcomes.
- Process variables including membrane properties and flow rates impact extracorporeal toxin clearance.
Implications:
- Understanding these factors guides the selection of appropriate extracorporeal therapy for poisoning cases.
- Optimizing hemodialysis prescriptions is crucial for effective management of acute intoxications.
- This approach supports enhanced poison removal when kidney function is compromised.

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...
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
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...
Pharmaceutical Poisoning: Treatment Strategies
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
Acute Kidney Injury V: Interprofessional Care
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...
Enhanced Elimination of Poison
Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
