OBJECTIVE It is important for preventing hyperventilation so as to improve the outcomes of patients with severe traumatic brain injuries. End-tidal CO2 (Petco2) reflects arterial CO2 (Paco2), noninvasively and continuously. The aim of this study is to examine the concordance between Paco2 and Petco2 among adults presenting to the emergency department with(More)
Extracorporeal life support has been used as an extension of conventional cardiopulmonary resuscitation (CPR). However, the appropriate indications for extracorporeal CPR (ECPR) including the duration of CPR are unknown. We present a case of a male, 37-year-old out-of-hospital cardiac arrest patient who received prolonged CPR followed by ECPR. Despite(More)
OBJECTIVES Treatment of intra-abdominal infections remains a challenge because of their polymicrobial nature and associated mortality risk. Broad-spectrum empiric coverage is usually required. This randomized study compared the efficacy and safety of intravenous piperacillin/tazobactam with those of intravenous imipenem/cilastatin in the treatment of 293(More)
AIMS The purpose of this study was to determine the clinical value of arterial minus end-tidal CO(2) [P(a-et)CO(2)] and alveolar dead space ventilation ratio (V(dA)/V(t)) as indicators of hospital mortality in patients that have been resuscitated from cardiac arrest at emergency department. MATERIALS AND METHODS Forty-four patients with a return of(More)
A 53-year-old male visited our emergency department after ingesting an unknown amount of methyl ethyl ketone peroxide. At presentation, he was hypotensive with reduced conscious level. Despite resuscitation, he died about 6 h after admission. On simple radiography, it was found that the patient had diffused gastric emphysema. We assumed that the unique(More)
BACKGROUND In severe sepsis and septic shock, global tissue hypoxia is a key development preceding multi-organ failure and death. OBJECTIVE Our aim was to find whether the initial low oxygen extraction ratio (OER) is related to the severity of organ dysfunction and to predict the in-hospital mortality in severe sepsis or septic shock patients. METHODS(More)
INTRODUCTION Unerring radiological interpretation is essential in discharged minor trauma patients without follow-up visits based on the rapid decision of emergency physicians (EPs). Misinterpretation may raise issues concerning patient care, reimbursement and lawsuits. The authors investigated the discrepancies and associated factors in radiological(More)
