Ba.k.round: This study a.ms to explore the significa.ce of serum a.yla.e levels in pa.ients with orga.ophosphorus pesticide (OP) poisoning a.d to provide a.new perspective for eva.ua.ing the severity a.d prognosis of OP poisoning. Methods: The clinica. da.a.of 67 pa.ients with a.ute OP poisoning, who ha. been trea.ed in the emergency depa.tment of the Genera. Hospita. of Ningxia.Medica. University between September 2020 a.d a.gust 2022, were retrospectively a.a.yzed. Using Spea.ma. ra.k.correla.ion, serum a.yla.e levels during a.mission a.d severity of poisoning correla.ed with discha.ge outcomes. Ba.ed on serum a.yla.e levels, receiver opera.ing cha.a.teristic curves were plotted to predict the severity a.d morta.ity of pa.ients who experience orga.ophospha.e poisoning. The optima. threshold serum a.yla.e level a. a.mission wa. determined ba.ed on the ma.imum Youden index. Results: Using Spea.ma. ra.k.correla.ion a.a.ysis, serum a.yla.e levels a. a.mission positively correla.ed with the severity of poisoning a.d discha.ge outcomes, but the degree of correla.ion wa. wea.

Ba.ed on the ma.imum Youden index, the optima. threshold of serum a.yla.e were 97.8 a.d 194.1 U/L when the degree of poisoning wa. severe a.d the discha.ge outcome of pa.ients wa. died. In compa.ison to pa.ients with serum a.yla.e levels ≤194.1 U/L a. a.mission, the OR va.ues of dea.h in pa.ients with serum a.yla.e levels >194.1 U/L a. a.mission wa. 15.944 (95% CI: 1.825–139.274). Conclusion: Serum a.yla.e levels in pa.ients with orga.ophospha.e poisoning correla.e with the degree of poisoning a.d discha.ge outcomes.
