Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.3K
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...

Autoxidation of Ethers to Peroxides and Hydroperoxides

9.9K
Ethers represent a class of chemical compounds that become more dangerous with prolonged storage because they tend to form explosive peroxides when standing in the air. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly oxidize to form hydroperoxides and dialkyl peroxides.

Peroxisomes01:24

Peroxisomes

21.9K
Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...

Pharmaceutical Poisoning: Treatment Strategies

95
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...

Enhanced Elimination of Poison01:26

Enhanced Elimination of Poison

986
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.
Renal excretion is the...

Toxic Reactions: Overview01:26

Toxic Reactions: Overview

3.2K
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,...

Summary

High-concentration peroxide ingestion can cause embolic events and death. Early hyperbaric oxygen therapy may improve outcomes, but routine endoscopy is not recommended for these poisonings.

Area of Science:

  • Toxicology
  • Emergency Medicine
  • Hyperbaric Medicine

Background:

  • High-concentration peroxide ingestion is a serious medical emergency.
  • Understanding the outcomes and optimal treatments is crucial for patient care.

Purpose of the Study:

  • To describe medical outcomes of high-concentration peroxide ingestion.
  • To examine the role of hyperbaric oxygen therapy.
  • To review the utility of endoscopy in these cases.

Main Methods:

  • Retrospective analysis of the National Poison Data System (NPDS).
  • Inclusion of 294 cases of >10% peroxide ingestion meeting specific criteria.
  • Analysis of embolic events, mortality, disability, and treatment effects using descriptive statistics and logistic regression.

Main Results:

  • 13.9% of patients experienced embolic events; 6.8% died or had continued disability.
  • Early hyperbaric oxygen therapy was associated with improved outcomes.
  • Endoscopy identified severe lesions in only 5 cases.

Conclusions:

  • High-concentration peroxide ingestion is linked to a significant incidence of embolic events and mortality.
  • Early hyperbaric oxygen therapy shows potential benefit.
  • Routine endoscopy is unlikely to be beneficial for managing these exposures.
