Types of Toxins01:36

Types of Toxins

3.0K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Toxic Reactions: Overview01:26

Toxic Reactions: Overview

1.6K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.1K
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...

Anticholinesterase Agents: Poisoning and Treatment01:26

Anticholinesterase Agents: Poisoning and Treatment

1.4K
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...

Depolarizing Blockers: Mechanism of Action01:28

Depolarizing Blockers: Mechanism of Action

2.4K
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because...

Depolarizing Blockers: Pharmocokinetics01:19

Depolarizing Blockers: Pharmocokinetics

497
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

Area of Science:

  • Toxicology
  • Neurology
  • Emergency Medicine

Background:

  • Acute delirium signifies underlying medical issues, frequently stemming from medication or substance toxicity.
  • Diagnostic challenges arise due to altered patient states and limited specific compound testing.
  • Recognizing toxidromes, distinct symptom clusters from specific compound classes, is crucial.

Purpose of the Study:

  • To review the clinical presentations, mechanisms, and management of common toxidromes.
  • To highlight the importance of identifying toxidromes for effective delirium treatment.
  • To provide a guide for clinicians managing toxicological emergencies presenting as delirium.

Main Methods:

  • Review of established medical literature on toxidromes and delirium.
  • Analysis of common toxidromes including anticholinergic, sympathomimetic, and hallucinogenic.
  • Inclusion of specific conditions like gamma-aminobutyric acid withdrawal and Wernicke encephalopathy.

Main Results:

  • Each toxidrome presents with a characteristic constellation of signs and symptoms.
  • Understanding the underlying mechanism aids in predicting clinical course and guiding treatment.
  • Cessation of the offending agent, supportive care, and specific antidotes are primary treatment modalities.

Conclusions:

  • Toxidromes are recognizable patterns of toxicity that are key to diagnosing and managing delirium.
  • Prompt recognition and targeted intervention, including antidotal therapy, improve patient outcomes.
  • This review provides essential information for managing patients with toxicological emergencies causing delirium.
