A dome-shaped chamber device enables the maximizing of the effect of SAW transmitted at a Rayleigh angle.

OBJECTIVE: In the Emergency Department, it would be worthwhile to treat pneumothorax patients on an outpatient basis by utilizing a small-calibre catheter and Heimlich valve insertion. We evaluated this treatment and compared it with the closed thoracostomy. METHODS: In this comparative study, the success rate, complications and recurrence rate of treating spontaneous pneumothorax patients by using a small-calibre catheter and Heimlch valve were compared with those of a similar-sized group treat

Radiographic studies in toxicology may confirm a diagnosis and assist in therapeutic intervention.

Hypertonic saline appears to decrease H2O2 in stimulated neutrophils. This may be a further beneficial role of hypertonic saline when used clinically as an early resuscitation fluid.

The BNP concentration used for the diagnosis of CHF in Korean people is considerably higher than the normal cut-off value of 100 pg/mL. In the non-CHF patients, the BNP values of women were influenced less by underlying disease. This suggests that the factors that influence BNP values in women are different from those in men.

OBJECTIVE: The present study aimed to determine the plausibility of forecasting the outbreak of diseases based on the weather by analysing the impact of atmospheric temperature and humidity on the occurrence of different diseases. METHODS: The subjects of the present study were the 30,434 patients who visited the ED in 1 year from 1 February 2005 to 3 February 2006. The present study analysed the correlation between the daily number of patients who suffered from 22 types of traumatic and non-tra

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 booster in wound management. METHODS: Questionnaires were sent to the directors of the emergency departments of resident training hospitals cer

Introduction. The rapid antigen test (RAT) plays an important role in the Emergency Room (ER). In this study, we investigated the effect of the RAT for influenza on clinical practice in an emergency department.Methods. A retrospective chart review was conducted considering two periods, namely before and after the 2009 influenza pandemic. The rate of antibiotic administration, the use of blood sample tests, the use of simple chest X-rays, the rate of antibiotic administration according to the res

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 remain unknown. Therefore, we conducted an experiment to apply hypoxia, hyperoxia, and other treatment with the goal of decreasing hypoxic neuronal cells damage, as reflected by cell survival,

Hypertonic saline has an immunomodulatory effect on polymorphonuclear cells through the TLR-4 pathway, and the interleukin-1β-associated pathway is influenced more by hypertonic saline than is the tumor necrosis factor-α-associated pathway.
