Abstract PDF: Purpose: The purpose of this study was to determine whether deoxyhemoglobin changes were associated with admission duration in carbon monoxide (CO)-poisoned patients.
Methods
This retrospective study included 181 patients who were able to breathe by themselves after CO poisoning. Arterial blood gas analysis was performed to measure their deoxyhemoglobin levels. Their baseline characteristics and clinical outcomes during hospitalization in the emergency department (ED) were collected and compared. To assess changes in deoxyhemoglobin levels, blood samples were taken immediately after patients presented to the ED and then again after 6 hours. For statistical analysis, logistic regression was utilized to determine the effect of deoxyhemoglobin changes on admission duration.
Results
The incidence rates of hypocapnia and hypoxemia at presentation after acute CO poisoning were 28.7% and 43.6%, respectively. Moreover, the magnitude of increasing deoxyhemoglobin levels in patients with hypoxemia (2.1 [1.7–3.1], p<0.001) and changes in deoxyhemoglobin levels appeared to have an impact on the length of hospitalization in the ED (odds ratio, 1.722; 95% confidence interval, 0.547–0.952; p<0.001).
Conclusion
In patients with acute CO poisoning, deoxyhemoglobin levels appeared to increase in those with hypoxemia, which in turn was associated with prolonged hospitalization.

Purpose: The purpose of this study is to find out the current status of toxicology laboratory operated by six locations nationwide and to investigate the satisfaction of emergency medical professionals who working at local and regional emergency medical centers. Methods: This survey was conducted prospective. It was conducted on 665 emergency medical professionals working at regional and regional emergency medical centers across the South Korea. Among them, the analysis was conducted with data that 510 emergency medical professionals who respond to this survey. The questionnaire was conducted on an online basis for a month. To ensure statistical significance, consider a dropout rate of 10% based on a minimum response recovery rate of 70%. 506 people were selected for the survey. Results: According to a survey on the status of addiction analysis room usage, the average monthly usage of addiction test rooms among respondents were 406 cases.71.0 cases (17.4%) of toxicology laboratory in Seoul and 71 cases (17.4%) in Gwangju. 32 cases (7.8%), 118 cases (29.0%) requested by toxicology laboratory in Busan, and the toxicology laboratory in Daegu. Eighty two cases (20.1%), Daejeon area 25 cases (6.1%), Wonju area toxicology laboratory was 78 (19.6%). According to a survey on the satisfaction of the addiction analysis room,Seoul (4.9±2.71) and Gwangju (4.8±2.52) showed high satisfaction. Conclusion: Due to the limited operation time of the four addiction analysis rooms currently in operation, the satisfaction level of addiction analysis by emergency medical professionals in the area is low due to the delay until the result is notified.

Abstract PDF

Purpose: The annual statistics for poisoning are reported based on the data from poison control centers in many advanced countries. In 2016 a study was conducted to analyze the 2016 Korea Poisoning status. This study was conducted to make a better annual report for poisoning statistics in Korea from a 2017-2018 national representative database. Methods: This study was a retrospective analysis of poisoning patients based on the data from an emergency department (ED) based injury in-depth surveillance project by the Korea Centers for Disease Control and Prevention in 2017-2018. Bite or sting injuries were not included. Results: A total of 17714 patients presented to 23 EDs because of poisoning. Adults above 20 years old age accounted for 84.6% of the population, while the proportion of intentional poisoning was 60.8%. The poisoning substance presented in the ED were therapeutic drugs (51.2%), gas (20.3%), pesticides (16.4%), and artificial substances (11.4%). Overall, 35% of patients were admitted for further treatment. The mortality was 2.4% (422 cases), and the most common fatal substances in order were carbon monoxide, other herbicides, and paraquat. Conclusion: This study showed the 2017-2018 status of poisoning in Korea. The prognosis is different from the cause of poisoning and the initial mental state of the patient. Therefore, appropriate methods for preventing poisoning and therapeutic plans in specific situations are needed.

Abstract PDF: 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.

Abstract PDF: Purpose: The purpose of this study was to identify the changes in the characteristics of patients with carbon monoxide (CO) poisoning, as well as the distinctive differences in intentionally exposed patients. Methods: The medical records of CO poisoning patients, who visited nine emergency departments between January 2010 and December 2011, were reviewed retrospectively. The clinical information including age, gender, hospitalization, type of discharge, cause and location of exposure, site of onset, concentration of initial blood carboxyhemoglobin (COHb), methods of treatment and presence of neurological complications was examined. The subjects were divided into an intentional and non-intentional group and the differences between them was compared. Results: A total 209 subjects were recruited. The median age was 38 years (29~49.5 years). They frequently complained of nausea and vomiting, and the most common exposures occurred in winter, normally in the home. The cause of exposure was usually fire, followed by incomplete combustion of fuels. The median initial blood COHb was 13.15%. The proportion of intentionally exposed patients was 21%. They were significantly younger, more frequently discharged against medical advice, and showed a higher initial blood COHb level (22.85%) than the non-intentional group. Conclusion: This study suggests that those with intentional CO poisoning are normally discharged against medical advice even when they have a higher initial COHb level. An adequate explanation of the delayed neurologic sequelae and short term follow-up observation is recommended for those patients with intentional exposure.
