Abstract:
Objective:To explore the clinical characteristics and prognostic factors of patients with acute glyphosate poisoning, and to provide reference for the comprehensive treatment and prognosis judgment of acute glyphosate poisoning.Methods:The complete hospitalized medical records data of 40 patients with acute glyphosate poisoning who were treated in the emergency department of Affiliated Hospital of Yangzhou University from 2014 to 2019 were collected in August 2020. According to the outcome during the follow-up period of 90 d after discharge from hospital, patients were divided into survival group ( n=33) and treatment failure group ( n=7) . The clinical characteristics of the two groups were analyzed. The influencing factors of prognosis were analyzed by binary logistic regression, and the receiver operating characteristic (ROC) curve was used to evaluate the value of white blood cell count level at admission to the prognosis of patients with acute glyphosate poisoning. Results:The average age of the 40 glyphosate poisoning patients was (57.70±19.72) years old, the oral dose was 100 (50, 200) ml, the hospital stay was 4.0 (1.0, 5.0) d, and the fatality rate was 17.5% (7/40) . The main clinical manifestations were the symptoms of the digestive tract, respiratory tract, cardiovascular system and nervous system. Logistic regression showed that white blood cell level at admission was an influencing factor for the prognosis of patients with acute glyphosate poisoning ( OR=1.148, 95% CI: 1.124-1.791, P=0.003) . The ROC curve showed that the best diagnostic cut-off value of white blood cell level at admission to the prognosis of acute glyphosate poisoning was 14.65×10 9/L, the area under the curve (AUC) was 0.9351. The sensitivity was 100.00%, and the specificity was 84.85%. Conclusion:High level of white blood cell at admission is a risk factor for the prognosis of acute glyphosate poisoning, and white blood cell level at admission has a certain predictive value for the prognosis of acute glyphosate poisoning.
