A Narrative Review on Magnesium Sulfate as a Game Changer in Reducing ICU Stays in Organophosphate Poisoning Cases

Organophosphate (OP) poisoning is a critical public health issue, particularly in agricultural regions where these compounds are extensively used as pesticides. The toxic effects of OP compounds arise from their inhibition of acetylcholinesterase, leading to an accumulation of acetylcholine and a subsequent cholinergic crisis, which can be fatal if not promptly treated. Traditional management of OP poisoning includes the administration of atropine and pralidoxime; however, these treatments often fall short of reducing the high morbidity and mortality associated with severe cases. Recent research has highlighted the potential of magnesium sulfate as an adjunctive treatment for OP poisoning. Magnesium sulfate exerts its beneficial effects through mechanisms such as calcium channel blockade and stabilization of neuromuscular junctions, which help mitigate the cholinergic hyperactivity induced by OP compounds. Clinical studies have shown that magnesium sulfate can significantly reduce the duration of intensive care unit (ICU) stays and improve overall patient outcomes. This narrative review aims to comprehensively analyze current insights into using magnesium sulfate to manage OP poisoning. It discusses the pathophysiology of OP poisoning, the pharmacological action of magnesium sulfate, and the clinical evidence supporting its use. Furthermore, the review will address the safety profile of magnesium sulfate and its potential role in current treatment guidelines. By synthesizing available evidence, this review seeks to establish magnesium sulfate as a game-changer in the management of OP poisoning, ultimately contributing to better clinical practices and patient outcomes.
