Gut decontamination in the poisoned patient.
Level 5 - mechanism / opinion, no new human data
Narrative review of gastrointestinal decontamination modalities without systematic review methodology
PubMed 39821212 · doi:10.1111/bcp.16379
What was done
This review evaluates gastrointestinal decontamination strategies for acute poisoning, assessing indications, contraindications, and technical aspects of orogastric lavage, oral activated charcoal (standard dose 1 g/kg), whole-bowel irrigation, endoscopy, and laparotomy based on existing volunteer and overdose literature.
What was found
The abstract reports no numerical outcome statistics or effect sizes. It reports that the standard single dose of activated charcoal is 1 g/kg, asserts that the strict 1-hour time window dogma is obsolete because modified-release formulations and pharmacobezoars persist in the gut for hours, and notes significant procedural risks such as aspiration and perforation.
Why it matters
It clarifies modern clinical toxicology practice by replacing rigid time windows with individualized risk assessment when deciding on gastrointestinal decontamination for acute poisonings.
Limits
The publication is a narrative review summarizing literature that the authors describe as generally low quality. The abstract provides no quantitative trial results, sample sizes, or precise risk-benefit statistics.
