ABSTRACT
BACKGROUND: Advance in sepsis management has increased the survival of patients with sepsis. However, severe sepsis and septic shock patients still have high mortality. We intend to verify the use of the procalcitonin (PCT) level as a prognosis marker in patients with severe sepsis or septic shock in the emergency department (ED). METHODS: ED Patients with severe sepsis or septic shock were enrolled in our study. We used mortality and Intensive Care Unit (ICU) days as a prognosis index, and compared the PCT level in survivors and non-survivors. We introduced the simplified acute physiology score 3(SAPS3) to assess the severity of the patients and analyzed whether or not the PCT level correlated with the severity index. RESULTS: The PCT level in septic shock patients [7.36 (0.92-33.69, IQR)] was higher than that in severe sepsis patients [3.24 (0.36-10.53, IQR)] (p = 0.04). However, there was no significant PCT level difference between survivors [median (IQR), 6.59 (0.60-29.25)] and non-survivors [median (IQR), 3.49 (0.40-20.41)] (p = 0.293). The SAPS3 score was higher in the non-survivor group [median (IQR), 64 (59.0-71.5)] than in the survivor group [median (IQR), 77 (68.5-82.0)] (p = 0.001). The PCT level did not correlate with either ICU days or hospital days. CONCLUSIONS: Using the PCT level as a prognosis factor in severe sepsis and septic shock patients in ED has little value.

PURPOSE: At present, the hemoglobin count is one of the most commonly performed clinical laboratory tests in the emergency department. However, the conventional method is invasive and permits only intermittent assessments. The aim of this study was to determine whether non-invasive hemoglobin measurements (SpHb) produce comparably accurate results to laboratory hemoglobin tests (tHb) in patients presented to the emergency department. METHODS: From May to July 2009, 217 patients who required hemoglobin tests after presenting to the emergency department of a hospital were enrolled. We measured hemoglobin values using the conventional method (tHb), and the non-invasive method (SpHb). The study population was classified into two groups: 'non-bleeding' and 'bleeding'. The concordance between tHb and SpHb was analyzed by the Pearson's correlation coefficient. RESULTS: A total of 217 data pairs were collected from 217 subjects, 193(88.9%) non-bleeding patients, 24(11.1%) bleeding patients. A total of 114 subjects were male (52.5%). The Pearson's correlation coefficient between tHb and SpHb was 0.814(p=0.000). In the 'non-bleeding' and 'bleeding' groups, the Pearson's correlation coefficients between tHb and SpHb were 0.779(p=0.000) and 0.788(p=0.000) respectively. CONCLUSION: Non-invasive SpHb measurement provides clinically acceptable accuracy compared to the conventional laboratory method (tHb) in the setting of the emergency department.

PURPOSE: While the use of coupling material (CM) during defibrillation is known to decrease transthoracic impedance more so than other materials elsewhere, the situation in Korea is unclear. The study assessed the use of paddleskin CM during defibrillation in South Korean emergency institutes (EIs) and measured the impedances. METHODS: From October 15 to October 19, 2009, 112 EIs (all of regional emergency medical centers (EMCs), specialized care centers, and local EMCs) were surveyed. Institute members were queried about their current use of paddleskin CMs during defibrillation. Indications for use were studied by means of a World Wide Web search, descriptions on the CM packaging, and telephone conversations with CM manufacturers and related people. Impedance measurements were recorded from April 13 to August 3, 2009. RESULTS: During defibrillation, 27 different CMs were used in the 108 EIs. Only nine institutes used CMs directly for defibrillation. Impedence of nine CMs could not be measured. The impedance values were 1.69, 1.71, 2.00, and 6.12 ohm for four CMs used for defibrillation; 6.66 and 11.94 ohm for two CMs used for electrodes; 9.71, 9.82, 11.57, 13.68, 13.89, 14.36, 18.31, and 19.66 ohm for eight CMs used for ultrasonography; and 14.05, 17.71, 35.44, and 41.15 ohm for four other CMs. CONCLUSION: More education and public information about the use of CMs for defibrillation are needed.

PURPOSE: A positive finding on a peripheral blood smear is the gold standard for the diagnosis of malaria. However, even for an expert microscopist, this test is a laborious and time consuming procedure. Therefore, it is crucial to have available a rapid and simple test that can be used in an emergency department environment. The aim of this study was to evaluate the usefulness of a rapid diagnostic kit for vivax malaria antigen and antibody among febrile patients visiting a local emergency medical center. METHODS: Peripheral blood smears, and malaria antigen and antibody tests were evaluated for 593 patients with fever and other commonly associated symptoms of malaria who visited our local emergency medical center between August 2008 and December 2009. RESULTS: Sixty nine cases of vivax malaria were confirmed by peripheral blood smear. Sensitivities of malaria antigen and antibody in patients of malaria were, respectively, 94.20% (65/69) and 76.81% (53/69); specificities were 100% (524/524) and 99.24% (520/524). CONCLUSION: Considering rapidity, high sensitivity and specificity, the rapid malaria antigen test is useful as an adjunctive diagnostic tool for detection of malaria infection in an emergency department environment.

PURPOSE: To describe the use of an emergency department (ED)-based, in-depth injury surveillance system to determine the incidence and mechanism of preschool children injury. METHODS: We prospectively studied and registered injured children under 7 years old, (n=5,921) whose injuries resulted in ED treatment from August 2006 to July 2008. We upgraded the checklist surveillance items, included place, accident mechanism, and agent factors. The ED physicians recorded the injury data on checklists in real time as they gave the ED orders. The recorded data were stored in computer networks and automatically coded, which enabled access to the raw data sources. The statistical data were calculated in detail by using relative frequency distribution from the raw data. RESULTS: A total of 29,548 injured patients visited the ED from August 2006 to July 2008. Preschool children injuries, except those from traffic accidents, were 5,921(20.0%). The most common sources of injuries were from blunt trauma (37%), slips(17%), and falls(16%). Among those admitted to our hospital, fall injuries and inhalation of foreign body accidents accounted for 7.6% and 7.5%, respectively. The larger proportion of fall injuries occurred from a height of less than 1 meter(82.2%). The frequency of injury mechanism differed according to age: fall(35%), blunt(19%), and burn(14%) were noted under 1 year old, compared to blunt(34%), fall(14%), and slip(13%) from between 1 to under 3 years of age, and blunt(37%), slip(19%), and fall (11%) between 3 to under 7 years of age. CONCLUSION: The ED-based preschool children injury surveillance system could provide a useful and efficient method to determine injury incidence and injury-related factors.

Formalin is a water-soluble, colorless, pungent, irritating and highly reactive gas. A 40% solution of formaldehyde in water, also known as formalin, is used as a disinfectant, antiseptic, deodorant, tissue fixative and embalming fluid. Ingestion can lead to immediate deleterious effects on almost all systems of the body including gastrointestinal tract, central nervous system, cardiovsacular system and hepato-renal system, causing gastrointestinal hemorrhage, cardiovsacular collapse, unconsciousness or convulsions, severe metabolic acidosis and acute respiratory distress syndrome. We treated a 39-year-old woman who ingested 300 ml formalin in a suicidal attempt. Despite hemodialysis, death occurred after 23 h.

PURPOSE: Natriuretic peptide levels are known to be associated with cardiac output and ventricular function. Recently it has been suggested that N-terminal pro-brain natriuretic peptide (NT-pro-BNP) is available as a prognostic marker for acute coronary syndrome patients. We compared NTpro- BNP levels between patients with and without major adverse cardiovascular events (MACEs) who visited the emergency room due to acute coronary syndrome. METHODS: We designed a case-only study with study subjects recruited retrospectively by medical chart review. Patients who visited the emergency room from 1 May 2006 to 31 February 2007 and were diagnosed with acute coronary syndrome were enrolled. Subjects who did not receive bedside measurement of NT-proBNP levels were excluded. To analyze by subtype of acute coronary syndrome, we classified study subjects into the following group: ST elevation myocardial infarction, non-ST elevation myocardial infarction, or unstable angina. RESULTS: The level of NT-proBNP was 2,592+/-917 pg/ml in MACEs patients, and 1,289+/-1,261 pg/ml in patients without MACEs, a statistically significant difference (p<0.0001). The MACEs patients showed higher level of NT-proBNP than patients without MACEs in the ST elevation myocardial infarction group (p=0.439), the non-ST elevation myocardial infarction group (p=0.004), and the unstable angina group (p=0.009). CONCLUSION: Initial bedside NT-pro-BNP levels are higher in MACEs patients. Although the study size was small and the result should be carefully interpreted, it supports the hypothesis that NT-pro-BNP can as a marker to evaluate MACEs in acute coronary syndrome.

A complete tracheal rupture due to blunt trauma is rare, and a high proportion of patients with this injury die prior to arrival at medical centers. Early diagnosis and prompt management is essential in order to reduce morbidity and mortality. A 38-year-old woman visited the emergency department after a fall from the 4th floor of a building. We confirmed that a complete tracheal disruption 4 cm above the carina by chest CT. We could not insert an endotracheal tube because the distal stump of the trachea was separated by 4 cm from the proximal stump, so we used percutaneous cardiopulmonary bypass for the prevention of hypoxia during the initial operative procedures. We performed resections and reconstruction of the injured trachea. Fourteen days after the operation we confirmed normal healing of the trachea with bronchoscopy. One year after the operation, the patient is healthy with no tracheal problems.

PURPOSE: Altered mental status (AMS) is a collective phrase that describes an undifferentiated assortment of disorders of mentation including impaired cognition, attention, awareness, and level of consciousness. Although AMS is a common chief complaint and a frequent issue in the emergency department (ED), the clinical surveys of AMS have not been conducted in Korea. We analyzed the AMS patients on the clinical basis. METHODS: From march 2002 to may 2002, we had enrolled prospectively 256 adult patients who visited the ED of Sanggye Paik Hospital because of AMS. The patients accompanied by AMS clinically were included, excluding patients caused by trauma, cerebrovascular accident with alert mentality. The clinical records were reviewed to analyze the clinical features of AMS, 9 months after discharge from ED. RESULTS: AMS was found in 256 patients which comprised the 2.2% of the ED patients during the test period, and 112 patients were admitted. The most commonly encountered mental status was drowsiness(36.3%), and the overall mortality rate 10.2%. The AMS was caused by neurogenic, metabolic, alcohol-related, psychogenic disorders in frequency accounting for most of AMS etiologies. CONCLUSION: This survey shows that the incidence of AMS is 2.2%, old age increases the rate of admission, and the common etiologies are neurogenic, metabolic, alcohol-related disorders. It seems prudent to approach the patients with AMS on the basis of etiologies and age.
