Abstract:
Objective:To analyze the characteristics of acute chemical poisoning cases and provide data support for establishing a regional network poisoning early warning and surveillance platform.Methods:In July 2023, patients with acute chemical poisoning who visited the Emergency Department, West China School of Public Health, and West China Fourth Hospital, Sichuan University from May 2016 to May 2023 were selected as the research subjects. Their characteristics such as gender, age, types of poisons, seasonal distribution, and the change trend of the number of poisoned people were analyzed. The annual trend of poisoning population was analyzed by linear regression.Results:There were a total of 2033 patients with acute chemical poisoning, among whom 32 were children (accounting for 1.57%). The gender was mainly female (1146 cases, accounting for 56.37%). The age ranged from 4 to 86 (34.60±10.45) years old. The top three poisonings in terms of acute chemical poisoning were carbon monoxide poisoning with 889 cases (accounting for 43.73%), diquat poisoning with 193 cases (accounting for 9.49%), and paraquat poisoning with 168 cases (accounting for 8.26%). Sedative-hypnotic drug poisoning was mainly in spring (65 cases, accounting for 43.62%), paraquat (65 cases, accounting for 38.69%) and diquat (68 cases, accounting for 35.23%) poisoning was mainly in summer, and carbon monoxide poisoning was mainly in winter (452 cases, accounting for 50.84%). The number of poisoning cases showed a significant increasing trend over the past seven years ( t=6.97, P<0.001). The detection rate of carbon monoxide poisoning was 95.61% (850/889), the detection rate of diquat poisoning was 28.50% (55/193), and the detection rate of paraquat poisoning was 14.88% (25/168) . Conclusion:The poisons of acute chemical poisoning are mainly carbon monoxide, diquat and paraquat. It is necessary to strengthen the publicity and education related to chemical poisoning, the supervision of poisons, and the construction of regional network poisoning early warning and surveillance platforms.
