Organophosphates (OPs) account for a large portion of suicides globally. OP manifests as cholinergic crises, which underlie respiratory failure. There are many pathways by which respiration is inhibited secondary to organophosphate poisoning. These include central as well as peripheral mechanisms, with central mechanisms predominating. We conducted a literature review in June 2017. PubMed, Embase, and Google Scholar were searched for studies that reported acute organophosphate poisoning in humans. In our review, data were collected from studies published during the years 2001 to 2016. The data consisted of 1,996 patients with organophosphate poisoning, of which 491 (24.6%) required ventilatory support secondary to respiratory failure. Treatment offered to OP poisoning patients should focus on its pathophysiology to benefit from the future outcomes. Recent advances direct the need for a central nervous system (CNS) protective strategy for future prevention and treatment of events associated with cholinergic crises.
