Purpose: This study examined the clinical and epidemiological characteristics of intensive care unit (ICU) patients admitted or died in the emergency medical center with acute-poisoning to investigate the variables related to the prognosis. Methods: The data were collected from poisoning patients admitted or died in the emergency medical center of a general hospital located in Seoul, from January 2014 to February 2020. The subjects of this study were 190 patients. The medical records were screened retrospectively, and the clinical and epidemiological characteristics of the patients in the emergency room (ER) and ICU were examined to investigate the contributing factors that influence the poor prognosis. Results: The study analyzed 182 patients who survived after being admitted to the intensive care unit (ICU). The results are as follows. The mental change (87.4%) was the most common symptom. Sedative poisoning (49.5%) was the commonest cause. For most patients, pneumonia (26.9%) was the most common complication. Hypotension (23.7%), tachycardia (42.1%), fever (15.8%), seizures (10.5%), dyspnea (2.6%), high poisoning severity score (PSS), type of toxic material, mechanical ventilator application (39.5%), inotropes application (39.5%), and pneumonia (55.3%) were correlated the LOS over 5 days in the ICU. 8 patients died. In the case of death pesticides and carbon monoxide were the main toxic materials; tachycardia, bradycardia, and hypotension were the main symptoms, and a mechanical ventilator and inotropes were applied. Conclusion: Patients with unstable vital signs, high PSS, and non-pharmaceutical poisoning had a prolonged LOS in the ICU and a poor prognosis.

Purpose: Some advanced countries have reported annual statistics for poisoning based on data from poison control centers. This study was conducted to propose a baseline format and statistics of poisoning in Korea from a national representative database. Methods: This study was a retrospective analysis of poisoning patients based on data from an emergency department (ED) based injury in-depth surveillance project by the Korea Centers for Disease Control and Prevention in 2016. Bite or sting injuries were not included. Variables related to poisoning were summarized using a similar format as the National Poison Data System in the United States. Results: A total of 7,820 poisoning patients presented to 23 EDs. Adults ${\geq}20$ years accounted for 84% of the population, while the proportion of intentional poisoning was 59.4%. The most common poisoning substances were therapeutic drugs (45%), gas (21%), pesticides (15%), and artificial toxic substances (13%). Overall, 34.5% of patients were admitted for further treatment. The mortality was 3.2% (248 cases), and the most common causative substances were carbon monoxide, glyphosate, and paraquat, in order. Conclusion: This study showed the recent status of poisoning in Korea. However, a comprehensive poisoning registry based on poison control centers may be required to provide more accurate national statistics in the future.

Objectives : Self-poisoning is the leading cause of visits to the emergency departments after a suicide attempts. This study is aimed to compare the patient characteristics according to the category of drugs ingested by the patients who attempted suicide. Methods : All medical charts were retrospectively reviewed from patients who visited the emergency center, at Seoul Medical Center, due to intentional self-poisoning from April of 2011 to July of 2019. We investigated the information regarding the subtype and quantity of the intoxication drug, how it was obtained, suicidal history, and psychiatric history, as well as, sociodemographic information. Variables were compared between prescription drug (PD) and non-prescription drug (NPD) poisoning groups. Results : The mean age of the NPD poisoning group was significantly lower than that of the PD poisoning group. The patient ratio of those enrolled in national health insurance and living with spouses were significantly higher in the NPD poisoning group. Compared to the NPD poisoning group, the PD poisoning group had a higher incidence of mental illnesses, underlying diseases and ratio of involuntary visit to the emergency department. Among the prescription drugs, the benzodiazepine poisoning group had a higher rate of self-prescription than the non-poisoning group, while the zolpidem poisoning group had a higher rate of the using someone else's prescription than other drugs. Each single drug poisoning group (benzodiazepine, zolpidem, and antidepressant single-agent) had a higher rate of no mental illness than each of the mixed-poisoning group. Conclusions : Guidelines for regulating non-prescription drugs are needed as a matter of suicide prevention. Also, this study suggests that clinicians need to be careful when issuing prescriptions and should suicidal risk according to patients' characteristics, duration of follow-up and type of drug packaging.

We experienced a case of occupational lead poisoning employed in a secondary lead smelting plant for 12 years. The patient was 39-year-old male and had been felt dizziness, recent memory impairment and intermittent severe abdominal pain for 2 years. On admission, blood lead level was $92.9{\mu}g/dl$, urinary lead level was $19.9{\mu}g/l$ and zinc protoporphyrin level was $226.0{\mu}g/dl$. On the blood test, hemoglobin was 10.6g/dl and showed normocytic normochromic anemia. There were no abnormal findings in the biochemical and hormonal tests. Decrease of I.Q. and use of words in speaking were found in the psychiatric and psychologic examinations. We observed the finding of motor polyneuropathy in the nerve conduction velocity test. Computed tomographic finding showed calcification lesions in the basal ganglia, dentate nuclei, caudate nuclei, and especially characteristic multiple calcifications were located in the subcortical white matter.

Purpose: Owing to organophosphate-pyrethroid mixtures are widely used, suicidal or unintentional poisoning is common. But there have been relatively few reports of poisoning. The purpose of this study is to evaluate the difference of the severity and toxicity between organophosphate-pyrethroid mixtures poisoning and single organophosphate poisoning. Methods: From August 2005 to July 2006, 65 patients presented with organophosphate-pyrethroid mixtures poisoning to emergency medical center. Date were gathered by report form it was drawn up. Results: 65 patients were enrolled in 28 hospitals and their mean age was $56.5{\pm}16.2$ years old. The most common cause of poisoning was suicide, in 52 cases(80%). Chlorpyrifos-cypermethrin, malathion-esfenvalerate were the most frequent chemicals involved, and the mean ingestion amount was 135.4ml. The most common symptom of the patients was nausea/vomiting, in 16 patients. The average GCS score was 13. The mean ICU stay was $4.4{\pm}5.2$ days, and mortality was 3.1%. Conclusion: The severity and toxicity of organophosphate-pyrethroid mixture poisoning were lower than that of single organophosphate poisoning.
Drug intoxication in children and adolescents is not uncommon in Korea. But the tendency of intoxication is changing with some factors, such as national surveillance system, Naderism and increasing concern among physicians. But the death rate of intoxication among adolescents is increasing in spite of decreasing total death rate of intoxication among children and adolescents. Therefore the physician must be concerned about the basic management of intoxication and figure out the common toxic substance among children and adolescents.

Purpose: Intentional poisoning is a major public health issue in many parts of the world. This study was conducted to provide details regarding the epidemiology of intentional poisoning in a metropolitan emergency department and to identify the changing patterns and epidemiology of poisoning. Methods: A retrospective study was conducted to evaluate intentional poisoning of patients who visited the emergency department in a tertiary teaching hospital between 2001 and 2015. All intentional poisoning-related emergency department visits over three five year periods (2001-2005 (P1), 2006-2010 (P2) and 2011-2015 (P3)) were reviewed to investigate trends in intentional poisoning patients. Information regarding patient sex, age, time from episode to admission, psychiatric history, type of intoxicants, alcohol co-ingestion, gastric lavage, charcoal administration, any previous suicide attempts, need for hospitalization and death before discharge was reviewed. Results: A total of 1269 patients were enrolled in this study. The number of patients admitted during each period was P1=515, P2=439 and P3=315. Comparison of the three groups revealed significant differences according to age (p<0.001), psychiatric history (p<0.001), alcohol co-ingestion (p=0.013), gastric lavage (p<0.001), charcoal administration (p<0.001), need for hospitalization (p=0.044), repeated attempt (p<0.001) and type of intoxicants (p<0.001). Conclusion: The average age of intentional poisoning patients has increased. While the use of sedatives and multiple drugs increased, the use of pesticides and the antihistamine decreased.

Purpose: No consensus currently exists regarding the maximal pressure of hyperbaric oxygen (HBO2) therapy performed within 24 hours of acute carbon monoxide (CO) poisoning. This study aimed to evaluate the difference in therapeutic effects according to the first HBO2 pressure (3.0 atmospheres absolute [ATA] vs. 2.8 ATA). Methods: We used prospectively collected registry data on CO poisoning at a tertiary academic hospital in the Republic of Korea. Adult patients with acute CO poisoning treated with HBO2 within 24 hours after arrival at the emergency department and without the use of additional HBO2 after 24 hours between January 2007 and February 2022 were included. Data from 595 patients were analyzed using propensity score matching (PSM). Patients with mild (non-intubated) and severe (intubated) poisoning were also compared. Neurocognitive outcomes at 1 month after CO poisoning were evaluated using the Global Deterioration Scale combined with neurological impairment. Results: After PSM, the neurocognitive outcomes at 1-month post-CO exposure were not significantly different between the 2.8 ATA (110 patients) and 3.0 ATA (55 patients) groups (p=1.000). Similarly, there was also no significant difference in outcomes in a subgroup analysis according to poisoning severity in matched patients (165 patients) (mild [non-intubated]: p=0.053; severe [intubated]: p=1.000). Conclusion: Neurocognitive sequelae at 1 month were not significantly different between HBO2 therapy pressures of 2.8 ATA and 3.0 ATA in patients with acute CO poisoning. In addition, the 1-month neurocognitive sequelae did not differ significantly between intubated and non-intubated patients.

Purpose: This study was conducted to identify predictors of serious poisoning in patients with snake bite based on initial findings. Methods: We conducted a retrospective study of patients with snake bite who were treated at the emergency department between January 2010 and December 2016. The patients were divided into two groups according to the severity of symptoms based on the traditional snakebite severity grading scale. The mild poisoning group (MP) was classified as those who had a grade I snakebite severity during the hospital stay, and the severe poisoning group (SP) was classified as patients who had grade I at the time of admission, but progressed to grade II-IV during hospitalization. Initial clinical manifestations and laboratory findings of the two groups were compared. Results: Bite to hospital time intervals of SP were longer than those of MP (p=0.034), and the local effect score (LES) was higher in SP (p<0.001). Laboratory analyses revealed that creatine phosphokinase (p=0.044), creatine phosphokinase MB isoenzyme (CK-MB, p=0.011) and serum amylase (p=0.008) were significantly higher in SP. LES, CK-MB and serum amylase were significant prognostic predictors as indicated by univariate logistic regression analysis. Multivariate analysis revealed the following two significant predictors: LES (odds ratio=3.983, p<0.001) and serum amylase (odds ratio=1.020, p=0.017). Conclusion: In managing cases of snake bites, clinical manifestations and laboratory findings must be carefully evaluated. LES and serum amylase are predictive factors for severe poisoning, which is especially important to rapid determination of the intensive care of the patient.

Purpose: The living standards vary between the urban and rural areas in Korea. This study aims to compare the characteristics of acute poisoning victims in urban and rural areas. Methods: A retrospective study was conducted over a period of 2 years from 2008 to 2009. The study group included adults over 19 year old with acute poisoning and who were later were admitted to the local emergency medical center located in Daegu, Korea. The exclusion criteria were 1) the victims of adverse effects of therapeutic doses of drugs, 2) the victims with chronic exposure and 3) the victims who were missing data in their emergency medical records. We divided the victims into the adult group (19-64 years old) and the old group (over 65 years old). Results: There were 569 acute poisoning victims during the study period, and they constituted 1.11% of the total ED visits (51,199). Four hundred seventy six patients were enrolled in this study. Out of the 359 acute poisoning victims, 252 victims were from urban areas and 107 victims were from rural areas. They showed statistical differences for gender, ED access, transport, toxins and the time to the ED. In the old group, 61 victims out of 117 were from urban areas and the remaining 56 victims were from rural areas. They showed statistical differences for gender, ED access, toxins and transport. Conclusion: Through the clinical comparison between the acute poisoning victims of urban and rural areas, we exposed the clinical differences between the urban and rural areas, and we concluded that prevention and education for acute poisoning should be generated differently between the two groups.
