Summary

Gastrointestinal decontamination aims to reduce poisoning effects. Activated charcoal is often preferred, but repeated doses may be needed, while induced emesis and intestinal cleansing have limited roles.

Area of Science:

  • Toxicology
  • Emergency Medicine
  • Gastroenterology

Background:

  • Acute poisoning is a significant cause of illness and death in all age groups.
  • Gastrointestinal decontamination is crucial for mitigating the severe consequences of ingested toxins.

Purpose of the Study:

  • To review and discuss various gastrointestinal decontamination methods for acute poisoning.
  • To evaluate the efficacy and indications of induced emesis, gastric lavage, activated charcoal, and intestinal cleansing.

Main Methods:

  • Literature review of established and debated gastrointestinal decontamination techniques.
  • Analysis of the role of Ipecac syrup, gastric lavage, activated charcoal, and intestinal lavage.

Main Results:

  • Induced emesis is limited to Ipecac syrup; gastric lavage remains controversial.
  • Activated charcoal is the treatment of choice for adsorbable toxins, with repeated doses beneficial for entero-enteric/entero-hepatic circulation.
  • Intestinal cleansing shows limited benefit and specific indications in acute poisoning management.

Conclusions:

  • Activated charcoal administration, potentially in repeated doses, is a primary method for gastrointestinal decontamination.
  • The utility of induced emesis and gastric lavage is debated, while intestinal cleansing has minimal application.
  • Optimizing poison elimination through gastrointestinal decontamination requires careful consideration of the toxin and method.
