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.
有机磷中毒是一个严重的公共卫生问题,尤其是在农业地区,这些化合物被广泛用作杀虫剂。有机磷化合物的毒性作用源于它们对乙酰胆碱酯酶的抑制,导致乙酰胆碱积累并随后引发胆碱能危象,如果不及时治疗可能会致命。有机磷中毒的传统治疗方法包括使用阿托品和氯解磷定;然而,这些治疗方法往往不足以降低与严重病例相关的高发病率和死亡率。最近的研究强调了硫酸镁作为有机磷中毒辅助治疗的潜力。硫酸镁通过钙通道阻滞和神经肌肉接头稳定等机制发挥其有益作用,这有助于减轻有机磷化合物引起的胆碱能亢进。临床研究表明,硫酸镁可以显著缩短重症监护病房(ICU)住院时间并改善患者总体预后。本叙述性综述旨在全面分析目前使用硫酸镁治疗有机磷中毒的见解。它讨论了有机磷中毒的病理生理学、硫酸镁的药理作用以及支持其使用的临床证据。此外,该综述还将探讨硫酸镁的安全性概况及其在当前治疗指南中的潜在作用。通过综合现有证据,本综述旨在将硫酸镁确立为有机磷中毒治疗中的变革性药物,最终促进更好的临床实践和患者预后。
