The 2025 Korean Guidelines for Cardiopulmonary Resuscitation include a first aid section developed through a systematic review and evidence appraisal. The revision aimed to strengthen prehospital first aid response capacity while reflecting the Korean healthcare system, field feasibility, and relevant legal and institutional contexts. The guidelines provide evidence-based recommendations for seven priority emergencies: adult chest pain suggestive of myocardial infarction, suspected acute ischemic stroke, asthma-related dyspnea, anaphylaxis, seizures, shock, and syncope. Core principles emphasize early recognition, prompt activation of emergency medical services, minimizing delays to definitive care, and safe condition-specific interventions. Key recommendations include assisting with patient-prescribed medications when appropriate (e.g., nitroglycerin, inhaled bronchodilators, and epinephrine autoinjectors), using structured stroke screening tools, preventing aspiration through proper positioning and withholding oral intake in patients at risk of dysphagia, administering oxygen only for hypoxemia, and initiating cardiopulmonary resuscitation in patients who are unconscious and not breathing normally. Seizure management focuses on safety and emergency medical services activation criteria, while care for shock and syncope emphasizes patient positioning and post-event assessment. These recommendations provide practical, evidence-based guidance for improving patient safety and outcomes in prehospital settings.
Objective The number of deaths due to acute poisoning (AP) is on the increase. It is crucial to predict AP patient mortality to identify those requiring intensive care for providing appropriate patient care as well as preserving medical resources. The aim of this study is to predict the risk of in-hospital mortality associated with AP using an artificial neural network (ANN) model.
Methods In this multicenter retrospective study, ANN and logistic regression models were constructed using the clinical and laboratory data of 1,304 patients seeking emergency treatment for AP. The ANN model was first trained on 912/1,304 (70%) randomly selected patients and then tested on the remaining 392/1,304 (30%). Receiver operating characteristic curve analysis was used to evaluate the mortality prediction of the two models.
Results Age, endotracheal intubation status, and intensive care unit admission were significant predictors of mortality in patients with AP in the multivariate logistic regression model. The ANN model indicated age, Glasgow Coma Scale, intensive care unit admission, and endotracheal intubation status were critical factors among the 12 independent variables related to in-hospital mortality. The area under the receiver operating characteristic curve for mortality prediction was significantly higher in the ANN model compared to the logistic regression model.
Conclusion This study establishes that the ANN model could be a valuable tool for predicting the risk of death following AP. Thus, it may facilitate effective patient triage and improve the outcomes.

Objective To determine the factors associated with unmet needs in immigrant patients complaining of abdominal pain, by analyzing those associated with the time from symptom onset to emergency room visit.
Methods We retrospectively reviewed the medical records of immigrants with abdominal pain who visited a tertiary hospital emergency department from January to December 2016. The dependent variable was the time from symptom onset to emergency room visit. The independent variables were age, sex, vital signs, disposition, health insurance status, date of visit, time of visit, level of education, employment status, economic satisfaction, marital status, living with family, duration of residence, having a native spouse, and subjective proficiency in Korean. We analyzed the association of the dependent variable with each independent variable.
Results In total, 102 immigrant patients with abdominal pain were enrolled in this study. The patients who had earlier visits had good subjective proficiency in Korean, high economic satisfaction, longer durations of residence, a tendency to have a native spouse, and a high employment rate. After linear regression analysis, the time from symptom onset to emergency room visit was negatively associated with employment (adjusted odds ratio, -13.67; 95% confidence interval, -23.25 to -4.09; P=0.006) and having a native spouse (adjusted odds ratio, -11.7; 95% confidence interval, -20.61 to -2.8; P=0.011).
Conclusion The factors influencing the time from symptom onset to emergency room visit in immigrant patients with abdominal pain are associated with social capital, which improves access to emergency care. Policies that improve immigrant access to emergency care should be considered.
Tracheobronchial disruption is one of the most severe injuries caused by blunt chest trauma. It may cause airway obstruction and resulting life-threatening respiratory deficiency. However, the clinical presentations are variable and frequently difficult to diagnose. We report a case of a previously healthy 16-year-old man with complete right main bronchial transection sustained after a vehicular accident, who had progressive dyspnea, subcutaneous emphysema in the neck and anterior chest wall, and bilateral tension pneumothorax. Prompt chest tube drainage for suspected bilateral tension pneumothorax and a tracheal intubation were performed. Shortly after the positive pressure ventilation, severe subcutaneous emphysema developed and he was at risk for developing shock. Additional chest tubes were inserted. An emergency bronchoscopy showed rupture of the right main bronchus. After changing to a double lumen endotracheal tube, the patient’s condition improved. A surgical closure was performed and postoperative bronchoscopy showed good repair. The patient was discharged without complications.

Objective Outbreaks of transmissible respiratory infection are suspected to have significant effects on the health of pediatric and geriatric patients. The objective was to assess the impact of the Middle East respiratory syndrome (MERS) outbreak on the use of emergency resources.
Methods An ecologic analysis of emergency department (ED) records between September and December 2015, was performed. Data was obtained from the National Emergency Department Information System database for Korea. All demographic and diagnostic data from patients presenting with febrile symptoms as a main complaint were collected. The data were compared to the equivalent period in the three years preceding the MERS outbreak in Korea.
Results Following the MERS outbreak, there was an increase in overall ED visits by febrile patients and the proportion of visits by febrile patients, relative to total ED attendances. This effect was more prominent in the children under five years. The duration of the chief complaint before ED arrival and the length of ED stay were significantly increased among younger pediatric patients. Decreased body temperature on arrival was observed in younger pediatric patients.
Conclusion MERS outbreak appears to have had a significant effects on ED use by febrile patients. The use of emergency care services by pediatric patients makes them more vulnerable to an outbreak of a transmissable disease. An effective strategy to control emergency center visits by non-urgent febrile patients and provide proper medical services is urgently needed.
