An Epidemiological Analysis Of 466 Patients With Acute Pesticide Poisoning

Objective By analyzing the epidemiological characteristics of 466 Hospitalized Patients with acute pesticide poisoning in the First Affiliated Hospital of University of South China for recent five years,to provide basis for further research on acute pesticide poisoning and scientific guidance for the diagnosis and treatment of acute pesticide poisoning in the region.Methods A retrospective study was performed to analyze 466 hospitalized patients with acute pesticide poisoning in the First Affiliated Hospital of University of South China from January 2014 to December 2018.Their gender,age,occupation,education level,patient source,place of residence,type of poison,The time of poisoning,the cause of poisoning,the route of poisoning,the length of hospital stay and the outcome were analyzed.Results A total of 466 hospitalized patients with acute pesticide poisoning were collected in the past 5 years.Among them,105 cases in 2014,115 cases in 2015,97 cases in 2016,74 cases in 2017,and 75 cases in 2018.The number of hospitalizations for acute pesticide poisoning has generally declined.Among the 466 patients with acute pesticide poisoning,211(45.28%)were male and 255(54.72%)were female,with a male to female ratio of 1:1.21.The majority of patients aged between 50 and 69,accounting for 35.62%.Poisoning patients mainly come from rural areas(90.99%).The number of farmers among poisoned patients is more than half(56.87%).The patient's education background is mainly primary school or below(61.16%).The causes of acute pesticide poisoning are classified into suicide and accident,and suicide is the main cause of acute pesticide poisoning(73.39%).Oral is the most common form of poisoning(94.64%).The main poison was anticoagulant rodenticide(29.40%),followed by organophosphate insecticide(25.75%).Acute pesticide poisoning mainly occurs in summer.The average length of hospital stay was(6.04±5.30)days.There were 150 patients(32.19%)who received blood purification treatment.The effective treatment rate of acute pesticide poisoning patients reached 92.27%.The cure rate was 47.85%,the improvement rate was 42.27%,the mortality rate was 2.36%,the rejection rate was 6.44%,and the referral rate was 1.07%.There are six(5.00%)patients died of organophosphorus pesticide poisoning,and four(33.33%)patients died of paraquat poisoning.Conclusion The acute pesticide poisoned patients were mainly elderly people,and the females were more than men.It occurs more in rural areas and mainly occurs in summer.Most of the poisoned patients are farmers and Low-educated.Suicide is the main cause of acute pesticide poisoning,and most patients are poisoned by oral pesticides.The main poison was anticoagulant rodenticide,followed by organophosphate insecticide.Targeted interventions can be taken based on these characteristics.
