BACKGROUND Most trauma patients visit the hospital via the emergency department. They are at high risk for tetanus infection because many trauma patients are wounded. Tetanus immunity in the Korean population has been revealed to be decreased in age groups over 20 years old. It is important for emergency physicians to vaccinate patients with the tetanus(More)
BACKGROUND Hypertonic saline is often used to resuscitate patients experiencing shock. In such conditions, polymorphonuclear cells and Toll-like receptors (TLRs) form an essential part of early induced innate immunity. OBJECTIVE To investigate the immunomodulatory effect of hypertonic saline on polymorphonuclear cells by evaluating the changes in TLR-4(More)
Purpose Postcardiac arrest syndrome (PCAS) shares many features with sepsis including plasma cytokine elevation with dysregulation of cytokine production, and the presence of endotoxin in plasma. PCAS is closely related to ischemia-reperfusion injury. During ischemia-reperfusion injury, neutrophil, which is the first line of innate immunity, plays a major(More)
BACKGROUND Prediction of the return of spontaneous circulation (ROSC) in cardiac arrest patients is a parameter for deciding when to stop cardiopulmonary resuscitation (CPR) or to start extracorporeal CPR. We investigated the change in transcutaneous PCO2 (PtcCO2) in cardiac arrest patients. METHODS This study was carried out as a retrospective chart(More)
Many patients are admitted to the emergency department due to trauma. Patients with massive hemorrhage and respiratory failure can fall into hypovolemic shock. Thereafter, oxygen is an essential part of the treatment of trauma patients, but the mechanisms of its effects in the management of trauma patients remains unknown. Therefore, we conducted an(More)
OBJECTIVE We compared patient satisfaction with scarring after facial laceration repair in the emergency department (ED) based on the specialty of the provider. METHODS Patients with facial lacerations admitted to the ED from 2009 to 2013 were divided into two groups. One group of patients underwent repair by an emergency physician (EP) and the other by a(More)
OBJECTIVES Continuous blood gas monitoring is frequently necessary in critically ill patients. Our aim was to assess the accuracy of transcutaneous CO₂ tension (PtcCO₂) monitoring in the emergency department (ED) assessment of hypotensive patients by comparing it with the gold standard of arterial blood gas analysis (ABGA). METHODS All patients receiving(More)
Introduction. Patients with symptoms suggestive of acute coronary syndrome (ACS) have various medical backgrounds and different stages of underlying coronary disease. Hence, patients entering the emergency room (ER) with ACS suggestive symptoms, present a challenge to emergency physicians. We hypothesized that a point-of-care test (POCT) for multiple(More)
Trauma-induced suppression of cellular immune function contributes to sepsis, multiple organ dysfunction syndrome (MODS) and mortality. Macrophage migration inhibitory factor (MIF) has been revealed to be central to several immune responses. However, the role of MIF in trauma-like conditions is unknown. Therefore, the present study evaluated MIF in(More)
