AbstractAbstract PDF
Purpose: This study investigated the differences between patients with acute carbon monoxide (CO) poisoning who visited the emergency department (ED) before and during the coronavirus disease 2019 (COVID-19) pandemic.
Methods
This was a single-center retrospective observational study. Patients with CO poisoning who visited the ED during the period from February 2020 to January 2023 were classified as the COVID-19 pandemic group, and those from February 2019 to January 2020 were classified as the non-pandemic group. Patients’ medical records were reviewed, their demographic and clinical characteristics were compared, and the length of stay in ED was checked. The time from admission to the ED to the start of hyperbaric oxygenation (HBO) was defined as the door-to-HBO time, and this parameter was compared between both groups.
Results
In total, 672 patients were included in this study. The proportion of intentional poisoning was significantly higher in the COVID-19 pandemic group than in the non-pandemic group (p=0.028). The proportion of intentional poisoning significantly increased in the 20- to 29-year-old age group during the COVID-19 pandemic (p<0.001). In addition, it took longer to initiate HBO in the COVID-19 pandemic group than in the non-pandemic group (p=0.001).
Conclusion
These findings suggest that pandemics of infectious diseases, such as COVID-19, increase the proportion of intentional CO poisoning, and it may take longer to initiate HBO after visiting the ED. Efforts will be needed to decrease intentional CO poisoning and length of stay in ED.

AbstractAbstract PDFSupplementary Material
Purpose: This study aimed to compare the clinical features of methanol and ethylene glycol poisoning.
Methods
This single-center retrospective observational study included patients with toxic alcohol poisoning who visited a regional emergency medical center. Patients with methanol and ethylene glycol poisoning from January 2004 to June 2023 were selected for the study using diagnostic codes.
Results
Twenty-two patients with toxic alcohol poisoning visited during the study period, with 11 patients for each category. Compared to methanol poisoning, ethylene glycol poisoning patients were more likely to have consumed alcohol for suicidal purposes (n=4 [36.36%] vs. n=8 [72.73%]) and were more likely to be drowsy (n=0 vs. n=6 [54.55%], p=0.016). The anion gap (25.43±8.35 mmol/L vs. 13.22±6.23 mmol/L, p=0.001) and lactic acid levels (1.785 [1.3–2.785] mmol/L vs. 9.90 [4.20–11.81] mmol/L, p=0.007) were higher in ethylene glycol poisoning patients than in methanol poisoning patients. Among alcohol dehydrogenase blockers, oral ethanol was administered to 10 patients (45.45%) (n=4 [36.36%] vs. n=6 [54.55%]), and intravenous ethanol was administered to six patients (n=4 [36.36%] vs. n=2 [18.18%]). Fomepizole was administered to two patients (9.09%) each, and renal replacement therapy was non-significantly more common in patients with ethylene glycol poisoning (n=8 [72.73%] vs. n=3 [27.27%], p=0.128). Three patients had delays in diagnosis and treatment, and while there were no fatalities, one patient was left with permanent vision damage.
Conclusion
Because these are uncommon types of poisoning and the clinical presentation is difficult to recognize early, healthcare providers should be familiar with toxic alcohol types and screen for them to ensure proper diagnosis and treatment.

AbstractAbstract PDF
Purpose: Alcohol ingestion enhances impulsivity and aggression, and has been proven to have a close relationship with suicide. This study investigates whether alcohol co-ingestion affects the Poisoning Severity Score (PSS) grade in patients with intentional poisoning. Methods: We conducted a retrospective analysis of intentional poisoning patients who visited the emergency department (ED) from January 1 to December 31, 2020. Patients were divided into non-drunken and drunken groups. We collected the data based on the medical records of the patients and serum ethanol level results recorded during initial blood tests at the ED. To grade the PSS, the highest score was assessed through clinical signs and test results during the hospital stay. A comparative analysis was conducted between the two groups. Results: A total of 277 patients were included in the study. 163 (58.8%) were in the non-drunken group, and 114 (41.2%) were in the drunken group. The PSS grade showed a significant difference between the two groups (p=0.002). While grade 1 (mild) was observed more in the non-drunken group, grade 2 (moderate) and grade 3 (severe) were seen more in the drunken group. In an ordinal logistic regression analysis, alcohol co-ingestion (adjusted odds ratio [aOR] 2.557, 95% confidence interval [CI] 1.554-4.208, p<0.001) was considered to be a risk factor for a higher PSS grade. There was no significant correlation between the serum ethanol level and the PSS grade. (p=0.568) Conclusion: Intentional poisoning patients with alcohol co-ingestion had a higher PSS. Hence close observation and aggressive treatment in the ED is warranted in such cases.
