Summary
Severe amlodipine poisoning requires swift intervention. This case study highlights the use of albumin dialysis and extracorporeal membrane oxygenation (ECMO) in managing life-threatening overdose, leading to successful patient recovery.
Area of Science:
- Toxicology
- Cardiology
- Critical Care Medicine
Background:
- Reports two cases of severe amlodipine poisoning (>1000 mg) from suicide attempts.
- Patients presented with severe vasoplegic shock, necessitating transfer via extracorporeal membrane oxygenation (ECMO) hotline.
Purpose of the Study:
- To describe the management of severe amlodipine poisoning.
- To evaluate the efficacy of albumin dialysis and ECMO in refractory vasoplegic shock.
- To propose a treatment algorithm for severe amlodipine overdose.
Main Methods:
- Both patients received standard therapy plus albumin dialysis.
- Veno-arterial ECMO was initiated due to persistent high vasopressor requirements (norepinephrine >2 µg/kg/minute).
- Adjunctive therapies included lipid emulsion and hydroxycobalamin, with noted technical challenges during continuous renal replacement therapy.
Main Results:
- Both patients were successfully weaned from ECMO and vasopressors.
- Patients were discharged from the intensive care unit after recovery.
- Albumin dialysis and ECMO were critical in managing refractory vasoplegic shock.
Conclusions:
- Swift intervention is crucial in severe amlodipine poisoning.
- Treatment timing and potential interactions between therapies must be carefully considered.
- A treatment algorithm integrating case severity and treatment timeframe is proposed based on these experiences.

01:26Anticholinesterase Agents: Poisoning and Treatment
1.5K
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is...

01:14Prevention of Further Absorption of Poison
1.2K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

1.0K
Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...

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.

01:26Heart Failure Drugs: Inotropic Agents
1.2K
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
