Purpose: This study was conducted to evaluate the clinical efficacy of pharmacologic treatment of amatoxin poisoning patients. Methods: Literature was accessed through PubMed, EMBASE, Cochrane library, KoreaMed, KISS and KMBASE. Studies relevant to human use of pharmacologic therapy including silymarin, penicillin and N-acetylcysteine (NAC) for amanita poisoning were included. Case reports, letters, editorials and papers with insufficient information were excluded. Comparison of clinical outcomes (especially mortality and liver transplantation rate) in each study was analyzed. Results: The final analysis included 13 retrospective studies. None of these studies showed direct comparisons of individual agents. Among 12 studies comparing silymarin vs penicillin, eight showed clinical superiority of silymarin. Among eight studies comparing silymarin with NAC, six showed clinical superiority of silymarin. Among seven studies of NAC vs penicillin, five showed clinical superiority of NAC. Conclusion: This systematic review suggested that clinical superiority of various pharmacological agents used to treat amatoxin poisoning is debatable. Nevertheless, the available evidence suggests it is reasonable to consider combinations of multiple agents for patients with amanita poisoning. Further studies are required to establish a treatment regimen for amanita poisoning.

Purpose: The purpose of this study is to evaluate the effectiveness and the adverse events of high dose insulin/euglycemia therapy in acute calcium channel blocker (CCB) poisoning. Methods: We developed a systematic search strategy and applied it to 4 electronic reference databases. We searched medical journals as well as the bibliographies of relevant articles. All forms of literature relevant to human use of high dose insulin for acute CCB poisoning were included. The literature search was conducted by two investigators in August, 2015 with publication language restricted to English and Korean. Case reports were divided between CCB overdose alone and multi-drug overdose including CCB. The effect and adverse event of high dose insulin and clinical outcome of each case were analyzed. Results: Among 55 searched studies, 20 studies were included. A prospective study, a retrospective study, a systematic review study, and 17 case reports were identified. Case reports consisted of 11 CCB alone and 12 multidrug overdose cases including CCB. Although most cases described significant clinical improvements, one of them showed no beneficial effect. Several adverse events including hypoglycemia and hypokalemia were reported. No significant sequalae from adverse events was reported. Conclusion: Although there were many case reports demonstrating successful use of high dose insulin for CCB poisoning, the effect cannot be estimated due to a possibility of publication bias. Therefore, high dose insulin/euglycemia therapy might be considered adjunctive therapy in cases of CCB intoxication refractory for standard therapy.

Purpose: The purpose of this study was to evaluate the usefulness of intravenous lipid emulsion as well as adverse events in acute poisoning patients. Methods: Literature was accessed through PubMed, EMBASE, Cochrane library, Web of science, and KoreaMed. All forms of literatures relevant to human use of intravenous lipid emulsion for acute poisoning were included. Cases reports or letters without description of clinical outcomes for each case were excluded. The literature search was conducted by two investigators in March, 2015, with publication language restricted to English and Korean. The effect, onset time, and adverse event of lipid emulsion and final outcome of each case were analyzed. Results: Eighty-one published articles were included, excluding articles whose title and abstract were not relevant to this study. No articles were classified as high level of evidence. Sixty-eight case reports were identified, consisting of 25 local anesthetics and 43 other drugs, such as tricyclic antidepressants and calcium channel blockers. Although most cases described significant clinical improvements, some of them showed no beneficial effect or worsening of clinical course. Several adverse events including hyperamylasemia and laboratory interference were reported. Conclusion: Although there were many case reports illustrating successful use of lipid for various drug poisonings, the effect cannot be estimated due to significant possibility of publication bias. Therefore, lipids might be considered in severe hemodynamic instability resulting from lipophilic drug poisoning, however further studies should follow to establish the use of lipid as the standard of care.

Purpose: Extracorporeal life support (ECLS) is a term used to describe a number of modalities including extracorporeal membrane oxygenation (ECMO) to support cardiac and/or pulmonary systems. The purpose of this study is to review the available evidence regarding the effect of ECLS in patients with acute poisoning. Methods: Electronic literature searches with PubMed, Embase, Cochrane library, and KoreaMed were conducted for identification of relevant studies addressing ECLS in treatment of acute poisoning. The literature search was conducted by two investigators in March, 2016 with publication language restricted to English and Korean. The toxic substance, technique of ECLS, and final outcome of each case were analyzed. Results: The final analysis included 64 articles including 55 case reports. There were no articles classified according to a high level of evidence such as randomized trial and prospective cohort study. ECLS treatment was used in the management of patients poisoned with 36 unique substances. Venovenous ECMO was performed in 4 cases. Among the reported cases, 10 patients died despite treatment with ECLS. Conclusion: Evidence supporting ECLS for patients with acute poisoning is inadequate. However, many case reports suggest that early consideration of ECLS in poisoned patients with refractory cardiac arrest or hemodynamic compromise refractory to standard therapies may be beneficial.

Purpose: The purpose of this study was to investigate the cause of acute fatal poisoning and the time of death by analyzing the National Emergency Department Information System (NEDIS) of South Korea. Methods: The NEDIS data from 2014 to 2018 excluding non-medical visits were used for this study. The patients with acute poisoning were extracted using diagnostic codes. The toxic substances were classified into pharmaceuticals, pesticides, gases, artificial poisonous substances, and natural toxic substances. Patients were classified according to the time of death, place of death, and region. In each case, the most causative substances of poisoning were identified. Results: There were 380,531 patients including poisoning-related diagnoses, of which 4,148 (1.1%) died, and the WHO age-standardized mortality rate was 4.8 per 100,000. Analysis of 2,702 death patients whose primary diagnosis was acute poisoning, the most common cause of poisoning death was pesticides (62%), followed by therapeutic drugs, gas, and artificial toxic substances. Herbicides were the most common pesticides at 64.5%. The proportion of mortality by time, hyperacute (< 6 h) 27.9%, acute (6-24 h) 32.6%, subacute (1-7 d) 29.7%, and delayed period ( >7 d) were 9.8%. Conclusion: This study suggests that the most common cause of poisoning death was pesticides, and 60% of deaths occurred within 24 hours. The 71% of mortality from pesticides occurred within 6-24 hours, but mortality from gas was mostly within 6 hours. According to the geographic region, the primary cause of poisoning death was varied to pesticides or pharmaceuticals.

Purpose: The purpose of this study was to conduct a systematic review to investigate the socio-economic benefits of the poison control center (PCC) and to assess whether telephone counseling at the poison control center affects the frequency of emergency room visits, hospitalization, and length of stay of patients with acute poisoning. Methods: The authors conducted a medical literature search of the PubMed, EMBASE, and Cochrane Library databases. Two reviewers evaluated the abstracts for eligibility, extracted the data, and assessed the study quality using a standardized tool. Key results such as the cost-benefit ratio, hospital stay days, unnecessary emergency room visits or hospitalizations, and reduced hospital charges were extracted from the studies. When meta-analysis was possible, it was performed using RevMan software (RevMan version 5.4). Results: Among 299 non-duplicated studies, 19 were relevant to the study questions. The cost-benefit ratios of PCC showed a wide range from 0.76 to 36 (average 6.8) according to the level of the medical expense of each country and whether the study included intentional poisoning. PCC reduced unnecessary visits to healthcare facilities. PCC consultation shortened the length of hospital stay by 1.82 (95% CI, 1.07-2.57) days. Conclusion: The systematic review and meta-analysis support the hypothesis that the PCC operation is cost-beneficial. However, when implementing the PCC concept in Korea in the future, it is necessary to prepare an institutional framework to ensure a cost-effective model.

Purpose: The aim of this study was to compare the clinical characteristics in emergency endotracheal intubation between patients with acute drug intoxication and medical disease. Methods: Data for airway registry collected in two emergency departments (ED) between April 2006 and March 2010 were reviewed retrospectively. The airway registry data included patient’s demographic information and variables such as Cormack-Lehane grade, 3-3-2 finger analysis, success rate, the number of attempts at intubation, complications of intubation, and clinical outcomes after intubation. Results: A total of 1480 patients were enrolled; 62 patients were classified as belonging to the intubation group after the drug intoxication group. No significant differences in Cormack-Lehane grade, 3-3-2 finger analysis, success rate, the number of attempts at intubation, and complications after intubation were observed between patients with acute drug intoxication and medical disease. However, significant difference was observed for indication of emergency endotracheal intubation. While emergency endotracheal intubations were usually performed in medical patients because of failure of airway patency, they were performed in intoxicated patients with the goal of preventing serious complications. Conclusion: Anatomical structures related to endotracheal intubation, the process and clinical outcome of intoxicated patients are not significantly different from those for medical patients.
