Objective The aim of this study was to investigate the clinical characteristics and analyze the risk factors of patients with acute dichlorvos poisoning combined with shock.Methods The clinical data of patients with acute dichlorvos poisoning admitted to the Peking University Third Hospital and the Fifth Medical Center of the PLA General Hospital between January 2019 and September 2020 were retrospectively analyzed,and demographic data,poisoning,clinical manifestations,laboratory tests,therapeutic measures and clinical outcomes were collected to establish a clinical database.The patients were divided into two groups:the shock group and the non-shock group,and the clinical data were compared between the two groups to analyze the clinical characteristics and prognosis of shock in acute dichlorvos poisoning,and the risk factors of shock in acute dichlorvos poisoning were analyzed by logistic regression.Results A total of 134 patients who met the criteria for acute dichlorvos poisoning were included in this study;the incidence of shock within 24 hours of admission was 39.6％(53/134),and 11 patients(8.21％)died in hospital;the in-hospital morbidity and mortality rate of patients in the shock group was higher than that in the non-shock group(20.8％vs.0.0％,P＜0.001).Symptoms of sphincter relaxation,coma,hypothermia,and organ function damage were more common in the shock group than in the non-shock group;and shock patients had longer hospitalization,ICU stay,and invasive ventilator use.Binary logistic regression analysis showed that the presence of sphincter relaxation manifestations(OR=10.888,95％CI:1.677-70.684,P=0.012)was an independent risk factor for comorbid shock in patients with acute dichlorvos poisoning,and the use of cholinesterase reanimators(OR=0.246,95％CI:0.072-0.846,P=0.026)was a protective factor for combined shock in patients with acute dichlorvos poisoning.Conclusions The incidence of shock in patients with acute dichlorvos poisoning is high and affects the clinical prognosis,and the presence of sphincter relaxation and the absence of cholinesterase reenergizers are independent risk factors for combined shock in patients with acute dichlorvos poisoning.
