RESUMO
Objective:To explore the clinical characteristics of poisoned patients with poisons purchase online.Methods:A retrospective case-control study was conducted on poisoned patients purchased poisons online from 1st January 2021 to 31th May 2022 in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University. The clinical data including sex, age, way of medical treatment, cause of poisoning, exposure routes, category of toxic drugs, gastric lavage, toxic detection and prognosis of patients were collected and compared with those patients obtained poisons at stores as the control group.Results:Totally 318 poisoned patients were included in this study, of which 44 (13.8%) were obtained poisons online. Compared with the patients obtained poisons at stores, the patients obtained poisons online were younger ( P<0.001), and had higher proportion of suicide intention ( P=0.006), more oral route exposure ( P=0.029), and more proportions of receiving gastric lavage before transfer to the hospital ( P=0.001). Pesticides and fertilizers with organic heterocycles were the main types of poisons in the online group, and there was no statistical difference in the distribution of poisons compared with the control group. Mixed drug poisoning was the leading cause in both online group (27.8%) and control group (38.8%) in drug overdose poisoned types, followed by dextromethorphan (16.7%) and estazolam (15.5%) in the online group. Conclusions:Young people are the main group getting poisons through the Internet. Health education should be strengthened for this group, and online shopping platforms should pay attention to the poisoning risk of potential overdose drugs or poisons transactions.
RESUMO
Objective:To explore the diagnostic value of the toxicant and drug detection in clinical poisoning diseases and analyze the clinical characteristics of patients with positive poison test.Methods:This study was a multicenter retrospective cohort study. Sampling and clinical information data were collected between October 1, 2020 and September 30, 2022 from 41 tertiary hospitals in and around Jiangsu province. The clinical characteristics of patients with positive toxicology tests were analyzed, and the correlation between the drug sampling situation and the test results was analyzed..Results:A total of 895 patients with clinical diagnosis or suspected poisoning were enrolled in this study. Among them, 652 patients had positive results, accounting for 72.85%. Among all positive patients, 506 patients were exposed to a single poison and 147 patients were exposed to multiple poisons. The top three poisons were pesticide herbicides (202 cases, 30.98%), sedative and psychotropic drugs (151 cases, 23.16%), and pesticide insecticides (97 cases, 14.88%). Among 541 patients with clear exposure history, the positive rate was 78.19%, and among 354 patients with unclear exposure history, the positive rate was 64.69%. The top three poisons (drugs) of patients with unclear exposure history were sedative and psychotropic (82, 12.58%), herbicide (26, 3.99%), and rodenticide (22, 3.37%). Patients who admitted to hospital for unexplained consciousness disorder, abnormal blood coagulation function and multiple organ dysfunction were more likely to obtain positive poison test results.Conclusions:There is uncertainty in the exposure history of poisoning diseases, so it is necessary to improve the detection of toxic substances as soon as possible. Toxicant testing should be considered when patients have impaired consciousness, abnormal coagulation function and multiple organ dysfunction.
