The characteristics and clinical outcomes of trauma patients transferred by a physician-staffed helicopter emergency medical service in Korea: a retrospective study.

Purpose: Helicopter transport with medical teams has been proven to be effective, with improvements in patient survival rates. This study compared and analyzed the clinical characteristics and treatment outcomes of trauma patients transported by doctor helicopters according to whether patients were transferred after a clinical evaluation or without a clinical evaluation.

Methods: This study retrospectively reviewed data from the Korean Trauma Data Bank of trauma patients who arrived at a regional trauma center through doctor helicopters from January 1, 2014, to December 31, 2022.

Combination of S100B and procalcitonin improves prognostic performance compared to either alone in patients with cardiac arrest: A prospective observational study.

This study aimed to determine whether the combination of procalcitonin (PCT) and S100B improves prognostic performance compared to either alone in cardiac arrest (CA) patients treated with targeted temperature management (TTM).We performed a prospective cohort study of CA patients treated with TTM. PCT and S100B levels were obtained at 0, 24, 48, and 72 hours after return of spontaneous circulation.

Accuracy of Bedside Ultrasound for the Diagnosis of Skull Fractures in Children Aged 0 to 4 Years.

Objectives: The aim of this study was to investigate the accuracy of bedside ultrasound (US) performed by emergency physicians for diagnosing skull fractures in children 0 to 4 years old compared with the accuracy of head computed tomography (CT). We also sought to investigate characteristics and precautions associated with US.

Methods: This single-center prospective study involved children 0 to 4 years old who had a history of head trauma.

Statin has more protective effects in AMI patients with higher plasma BNP or NT-proBNP level, but not with lower left ventricular ejection fraction.

Background: The benefit of statin therapy in patients with higher grades of heart failure has yet to be determined. The present study investigated whether statin therapy affects major composite outcomes (MCOs) and all-cause mortality in patients with acute myocardial infarction (AMI) within 1 year after AMI, according to their plasma natriuretic peptide (NP) levels and left ventricular ejection fraction (LVEF).

Methods: A total of 11,492 patients with AMI from two nationwide registry databases in Korea were analyzed.

Comparison of epidemiology, emergency care, and outcomes of acute ischemic stroke between young adults and elderly in Korean population: a multicenter observational study.

Stroke in young adults has been known to show a lower incidence and a better prognosis. Only a few studies have examined the epidemiology and outcomes of ischemic stroke in young adults and compared them with the elderly in Korean population. All consecutive patients with ischemic stroke visiting 29 participating emergency departments were enrolled from November 2007 to October 2009.

Factors associated with pneumonia in post-cardiac arrest patients receiving therapeutic hypothermia.

Aim: The aim of this study is to investigate risk factors associated with the development of pneumonia during the first 7 days of admission in survivors of cardiac arrest receiving therapeutic hypothermia.

Methods: A total of 123 patients receiving therapeutic hypothermia after out-of-hospital cardiac arrest between January 2008 and December 2010 were enrolled. Study populations were categorized as "pneumonia present" [P (+)] and "pneumonia absent" [P (-)] contingent upon the development of pneumonia during the first 7 days of admission.

Blood ammonia is a predictive biomarker of neurologic outcome in cardiac arrest patients treated with therapeutic hypothermia.

Purpose: The aim of this study was to investigate the value of commonly examined laboratory measurements, including ammonia and lactate, in predicting neurologic outcome of out-of-hospital cardiac arrest (OHCA) patients treated with therapeutic hypothermia (TH).

Methods: This was a retrospective cohort study of patients with a return of spontaneous circulation after OHCA who were treated with TH between February 2007 and July 2010. We measured typical blood measurements on arrival at the emergency department.
