AbstractAbstract PDF
Purpose: This study examined the clinical characteristics of severe elderly poisoning patients to determine the factors that can prevent them. Methods: Data were collected from patients over 65 years of age presenting to the emergency center with poisoning from 2013 to 2018. Their medical records were analyzed retrospectively, and patients with a poisoning severity score of three or more were defined as the severe poisoning group. The risk factors were evaluated by univariate and multivariate analysis. Results: This study analyzed 292 patients, of whom 37 (12.7%) belonged to the severe poisoning group. The severe poisoning group showed a significantly higher association with pesticide poisoning and intentional suicide attempts. Loneliness and somatization were the cause of the suicidal ideas. No significant differences in age, sex, drinking, ingestion time, poisonous materials other than pesticides, and neuropsychological consultation were observed between the two groups. Conclusion: The severe elderly poisoning patients were the result of intentional poisoning for suicide. Loneliness and somatization were the most influential causes of suicidal poisoning. Therefore, psychiatric screening and frequent medical treatment for elderly people are required to prevent severe poisoning in elderly patients.

AbstractAbstract PDF
Purpose: This study estimated the incidence of delirium and associated risk factors and outcomes in ICU patients with acute poisoning. Methods: Data were collected from ICU patients over 18 years of age that were admitted via the emergency center after presenting with poisoning from 2010 to 2015. Delirium was assessed retrospectively using the Intensive Care Delirium Screening Checklist (ICDSC). Risk factors were evaluated by univariate and multivariate analysis. Results: A total of 199 patients participated in this study and 68 (34.2%) were diagnosed with delirium based on the ICDSC score. The delirium group showed a significantly higher association with prolonged length of stay in the hospital and ICU in comparison with the non-delirium group. The delirium group was associated with greater use of physical restraint. A statistically greater number of patients with pharmaceutical substance poisoning developed delirium over a short period of time than those with non-pharmaceutical substance poisoning. There was no significant difference between the two groups with respect to age, sex, past history, GCS score, vital signs, application of ventilator care and renal replacement therapy. Conclusion: The finding that the delirium group had a greater length of stay in both the hospital and the ICU is consistent with the results of previous worldwide studies of the effects of delirium on the prognosis of patients who were admitted to the ICU, suggesting the possibility for domestic application. Additionally, use of physical restraint was positively related to the incidence of delirium. Thus, interventions for minimizing the use of physical restraints and considering alternatives are needed.

AbstractAbstract PDF
Purpose: Aspiration pneumonia is an important complication of drug intoxication with decreased mental status. The purpose of the study is to investigate the risk factors of aspiration pneumonia in the patients of benzodiazepine overdose with or without co-ingestion of other drugs. Methods: A retrospective chart review of patients who visited the emergency department between January 2012 and December 2014 was conducted. Demographic data, time from ingestion to visit, initial vital signs, symptoms, mental status, medical history, laboratory results, chest radiological findings and co-ingested medications were recorded. Multiple logistic analyses were performed to verify the association between variables and the development of aspiration pneumonia. Results: A total of 249 patients presented to the emergency department with benzodiazepine overdose. Aspiration pneumonia had developed in 24 patients (9.6%). Univariate analysis revealed time from ingestion to visit was longer, Glasgow coma scale score was lower, hypoxia was presented, leukocytosis was shown, types of ingested drugs was high, less activated charcoal was applied and tricyclic antidepressants was taken in patients that developed aspiration pneumonia. Time from ingestion to visit (odds ratio (OR) 1.121, 95% confidence interval (CI), 1.057-1.189, p=0.000), GCS score (OR 0.724. 95% CI, 0.624-0.839, p=0.000), oxygen saturation (OR 0.895, 95% CI, 0.835-0.959, p=0.002), and co-ingestion of TCA (OR 4.595, 95% CI, 1.169-18.063, p=0.029) were identified as risk factors of morbidity of aspiration pneumonia upon multiple logistic regression analysis. Conclusion: Time from ingestion to visit, low GCS score, low oxygen saturation and co-ingestion of TCA were risk factors of the development of aspiration pneumonia in benzodiazepine overdose patients.
