What does the acronym "SLUDGE" stand for in the context of chemical nerve agent symptoms?

The acronym "SLUDGE" is an important mnemonic used in the context of chemical nerve agent exposure. It specifically stands for the symptoms commonly associated with cholinergic crisis, which typically occurs after exposure to nerve agents. The symptoms included in this acronym are salivation (excessive drooling), lacrimation (tearing of eyes), urination (increased urination), defecation (increased bowel movements), gastroenteritis (nausea, vomiting, diarrhea), and emesis (vomiting).

These symptoms result from the overstimulation of the parasympathetic nervous system due to the accumulation of acetylcholine, a neurotransmitter that is normally broken down by the enzyme acetylcholinesterase. When nerve agents inhibit this enzyme, acetylcholine levels rise, leading to the vivid manifestations represented by the SLUDGE acronym.

This mnemonic helps first responders, including tactical medics, quickly recognize the signs of nerve agent poisoning and take appropriate actions, such as administering antidotes like atropine and pralidoxime, which counteract the effects of excessive acetylcholine. Understanding this acronym is crucial in emergency medical services, especially in tactical or high-risk environments where chemical exposures may occur.
