Abstract:
Caustic self-poisoning is a major health hazard, which affects any age, but is particularly serious among the elderly. Household bleach is a caustic that contains 3% to 6% sodium hypochlorite solution, one of the most common agents in unintentional caustic poisoning. In this clinical case, we present a household bleach self-poisoning by an older man with no relevant medical history. He presented with extensive burns on the oral cavity mucosa and tongue, requiring orotracheal intubation by video laryngoscopy. He was then admitted to the intensive care unit, where he evolved poorly. Given the poor prognosis and the lack of physiological reserve for the invasiveness required for a surgical approach, a conservative strategy was chosen after a multidisciplinary team discussion. With the conservative strategy, the patient survived, being discharged to the general ward after one month, where he underwent a Stamm gastrostomy and placement of a percutaneous endoscopic gastrostomy. In the follow-up consultation three months later, the patient was found to be weakened, with high frailty status, presenting anxiety, depression, and causing high family burden.

Prevention of Further Absorption of Poison
Enhanced Elimination of Poison
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.

Antidotes
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,...
Toxic Reactions: Overview
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,...
