Intubation in patients with respiratory failure can be avoided by high-flow nasal cannula (HFNC) use. However, it is unclear whether waiting until HFNC fails, which would delay intubation, has adverse effects. The present retrospective observational study assessed overall ICU mortality and other hospital outcomes of who received therapy that failed.All consecutive one tertiary failed then required intubation between January 2013 March 2014 were enrolled classified according to started early...
Although the utilization of extracorporeal membrane oxygenation (ECMO) is increasing and its technology evolving, only a few epidemiologic reports have described uses outcomes ECMO. The aim this study was to investigate changes in survival rate patients supported with ECMO for severe respiratory failure Korea. This multicenter on consecutive who underwent across 16 hospitals records all required acute between 2012 2015 were retrospectively reviewed, analyzed over time. During period, 5552...
Background The Korean Obstructive Lung Disease (KOLD) Cohort Study is a prospective longitudinal study of patients with chronic obstructive pulmonary disease (COPD), asthma, or other unclassified lung diseases. It was designed to develop new classification models and biomarkers that predict clinically relevant outcomes for Methods Patients over 18 years old who have respiratory symptoms airflow limitations bronchial hyper-responsiveness were enrolled at 17 centers in South Korea. After...
The modified early warning score (MEWS) is used to predict patient intensive care unit (ICU) admission and mortality. Lactate (LA) in the blood lactate (BLA) measured evaluate disease severity treatment efficacy patients with severe sepsis/septic shock. usefulness of a combination MEWS BLA ICU transfer shock unclear. We evaluated whether use enhances prediction mortality hospitalized shock.Patients who were screened or contacted by medical emergency team between January 2012 August enrolled...
Mortality rates associated with sepsis have increased progressively in Korea, but domestic epidemiologic data remain limited. The objective of this study was to investigate the characteristics, management and clinical outcomes patients Korea.This is a multicenter retrospective cohort study. A total 64,021 adult who visited an emergency department (ED) within one 19 participating hospitals during 1-month period were screened for eligibility. Among these, diagnosed based on third International...
Background: The proportion of elderly patients in the intensive care unit population is increasing. Although Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) score widely used for survival prediction extracorporeal membrane oxygenation (ECMO) patients, it questionable whether RESP applicable to older patients. aim this study was investigate applicability Korean cohort.
Bacterial pneumonia occurring after respiratory viral infection is common. However, the predominant bacterial species causing secondary to infections other than influenza remain unknown. The purpose of this study was know whether pathogens post-viral vary according type virus.Study subjects were 5,298 patients, who underwent multiplex real-time polymerase chain reaction for simultaneous detection viruses, among visited emergency department or outpatient clinic with symptoms at Ulsan...
To investigate the impact of normothermia on compliance with sepsis bundles and in-hospital mortality in patients who present to emergency departments.Retrospective multicenter observational study.Nineteen university-affiliated hospitals Korean Sepsis Alliance participated this study. Data were collected regarding visited departments for during 1-month period. The divided into three groups based their body temperature at time triage department (i.e., hypothermia [< 36°C] vs [36-38°C]...
Background Circulating tumor cells (CTCs) are frequently detected in patients with advanced-stage malignant tumors and could act as a predictor of poor prognosis. However, there is paucity data on the relationship between CTC number primary volume lung cancer. Therefore, our study aimed to evaluate adenocarcinoma. Methods We collected blood samples from 21 treatment-naive adenocarcinoma 73 healthy individuals. To count CTCs, we used enrichment method based fluid-assisted separation...
There are limited data regarding prolonged extracorporeal membrane oxygenation (ECMO) support, despite increase in ECMO use and duration patients with respiratory failure. The objective of this study was to investigate the outcomes severe acute failure supported for more than 28 days.
Systemic glucocorticoid treatment is highly recommended in critically ill coronavirus disease 2019 (COVID-19) patients. However, secondary fungal infections are of concern such Here, we describe the first case COVID-19-associated invasive pulmonary aspergillosis (CAPA) and mucormycosis (CAM) coinfection a COVID-19 positive immunocompetent patient Korea. A 69-year-old man was admitted to our hospital with pneumonia. He had no underlying comorbidities not taking medications. received...
Bronchoscopy has a lower diagnostic yield for peripheral lung lesions (PLL). Endobronchial ultrasound guide sheath transbronchial biopsy (EBUS GS TBLB) been used to overcome such limitation. Recent studies revealed that combined methods (e.g., EBUS TBLB plus electromagnetic navigation [EMN] or virtual bronchoscopic [VBN]) further improve the yield. However, those systems are associated with high cost burden. Accordingly, we attempted use VBN by computed tomography (CT) workstation (Aquarius...
Pulmonary vein stenosis, which is one of the rare complications radiofrequency catheter ablation for atrial fibrillation, has various symptoms. Here, we report a case massive hemoptysis due to pulmonary stenosis following ablation, was successfully managed with pneumonectomy.
Usually, high-flow nasal cannula (HFNC) therapy is indicated for de novo acute hypoxemic respiratory failure (AHRF). Although only a few researches have examined the effectiveness of HFNC with hypercapnia, this often performed under such conditions various reasons. We investigated AHRF patients hypercapnia compared to those without hypercapnia.All consecutive receiving between January 2012 and June 2018 at university hospital were enrolled classified into nonhypercapnic hypercapnic groups....
Abstract Background Rapid response system (RRS) is being increasingly adopted to improve patient safety in hospitals worldwide. However, predictors of survival outcome after RRS activation because unexpected clinical deterioration are not well defined. We investigated whether hospital length stay (LOS) before can predict the outcomes. Methods Using a nationwide multicenter database, we identified patients for whom was activated during hospitalization at 9 tertiary referral South Korea...
Purpose: Low-attenuation muscle area (LAMA) and normal-attenuation (NAMA) indicate lipid-rich lipid-poor skeletal areas, respectively. Additionally, intermuscular adipose tissue (IMAT) indicates localized fat between groups. In this study, we aimed to evaluate the intramuscular infiltration in individuals with chronic obstructive pulmonary disease (COPD) by performing quantitative assessment of LAMA, NAMA, IMAT observed on abdominopelvic computed tomography (APCT) images. Patients Methods:...
Background: Early recognition of the signs and symptoms clinical deterioration could diminish incidence cardiopulmonary arrest.The present study investigates outcomes with respect to arrest rates in institutions without rapid response systems (RRSs) current level rate tertiary hospitals.Methods: This was a retrospective based on data from 14 hospitals.Cardiopulmonary resuscitation (CPR) reports were obtained each hospital include number events adult patients general ward, annual admission...
A 61-year-old woman came to the hospital with dyspnea and pleural effusion on chest radiography. She underwent repeated thoracentesis, transbronchial lung biopsy, bronchoalveolar lavage, thoracoscopic biopsy talc pleurodesis, but diagnosis of her was uncertain. Positron emission tomography showed multiple lymphadenopathies, so she endobronchial ultrasound-guided needle aspiration mediastinal lymph nodes. Here, we report a case malignant mesothelioma that eventually diagnosed by aspiration....
Idiopathic pulmonary arterial hypertension (IPAH) is an incurable disease with high mortality. Although most studies recommend anticoagulation treatment for IPAH, the benefits are uncertain, particularly in Korea, where it has not been studied. The purpose of this study was to evaluate survival outcomes Korean patients IPAH treated warfarin.We performed a retrospective cohort diagnosed previously (PAH) at Asan Medical Center between January 1994 and February 2013. We excluded associated PAH,...
