Objective To investigate the level of basic life support (BLS) skill retention medical interns 6 and 12 months after BLS education analyse correlation between clinical experience cardiopulmonary resuscitation (CPR) retention. Materials methods The baseline performance skills in doctors during their internship was tested immediately provider course. subjects were divided into two groups, which using same method or months. Data on subjects' CPR collected through records—specifically, number...
Introduction Following a chemical, biological, radiation and nuclear (CBRN) incident, prompt establishment of an advanced airway is required for patients with respiratory failure within the warm zone, while wearing personal protective equipment (PPE). Previous studies reported that intubation attempts were prolonged, incidence esophageal was increased conventional Macintosh laryngoscope (McL), CBRN-PPE. Pentax-AWS (AWS), recently introduced portable video laryngoscope, compared McL to test...
The two-thumb encircling (TTE) technique often results in suboptimal cardiac compression and does not meet the requirements of current resuscitation guidelines. We compared this with vertical (VTT) technique, our novel modification TTE technique.This was a prospective randomised crossover simulation study out-of-hospital infant cardiopulmonary (CPR). Participants who had completed basic life support course performed 10 cycles compressions on manikin for each technique.We enrolled 36 medical...
BACKGROUND: Accurate and timely diagnosis of acute surgical disease in pregnant patient is challenging.Although magnetic resonance imaging (MRI) the most accurate modality to diagnose appendicitis patients, it often used as a last resort because high cost long scan time.We performed this study analyze differential diagnoses appendix MRI investigate if there are any blood tests that can predict condition patients. METHODS:A retrospective, cross-sectional was conducted on 46 patients who...
Chronic gastritis could activate a systemic inflammatory response that result in adverse lipid profiles. To determine the severity of chronic gastritis, Helicobacter pylori (HP), mononuclear cell (lymphocytes and plasma cells), neutrophil scores were assessed on basis updated Sydney system (USS), which is widely used for histological grading. The aim this study was to assess relationships between gastric features profile levels. This included 15,322 males 5929 females who underwent health...
Background For the basic life support (BLS) renewal course, we have devised a new educational programme entitled small-group-discussion (SGD) using personalised video-based debriefing. Objective We compared efficacy in BLS skill improvement of SGD with currently used practice-while-watching (PWW) programme, which uses standardised education video. Method This was prospective, cluster randomised study, conducted single centre, over 6 months from May 2009 to October 2009. Training performed...
Early prediction of the clinical outcomes for health care-associated pneumonia (HCAP) patients is challenging.This first study to evaluate procalcitonin (PCT) as a predictor in HCAP patients.We conducted an observational based on data prospectively collected between 2011 and 2014. Outcome variables were intensive care unit (ICU) admission 30-day mortality. PCT was categorized into three groups: <0.5, 0.5-2.0, >2.0 ng/ml. We analysed multiple including age, sex, comorbidities, findings, group...
Background A hyper-intense vessel sign on fluid attenuated inversion recovery magnetic resonance imaging (FHV) represents slow blood flow in the cerebral arteries. Purpose To investigate relationship between proximal FHV (pFHV) initial (MRI) and status of culprit (stenosis, obstruction) hyper-acute strokes affecting territory middle artery (MCA). Material Methods The study participants consisted 105 patients presenting to emergency department (ED) with acute MCA infarction within 4.5 h onset...
Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation (CPR). The rate metronome should be set between 100 120 ticks/minute speed ventilation may have crucial effect on ventilation. We compared three different rates (100, 110, ticks/minute) investigate its during metronome-guided 30:2 CPR.This prospective, randomized, crossover observational study using RespiTrainer○r. To simulate 30 chest compressions, one investigator...
Aim. To determine whether the chest compression depth of at least 1/3 Anteroposterior (AP) diameter and about 5 cm is appropriate for children all age groups via computed tomography. Methods. The AP chest, anterior wall diameter, compressible (Cd) were measured lower half sternum patients aged 1-18 years using mean ratio to Cd adult was used as limit, 6 upper limit. Also, resulting in a residual <1 considered cause internal injury potentially. With limits, ratios compared when...
To compare the effectiveness of GlideRite stylet with conventional malleable (CMS) in endotracheal intubation (ETI) by Macintosh laryngoscope.This study is a randomized, crossover, simulation study. Participants performed ETI using both and CMS normal airway model tongue edema (simulated difficult resulting lower percentage glottic opening [POGO]).In models, all 36 participants successfully two stylets on first attempt. In model, there was no difference time required for (TETI) or ease...
Objective: This study was conducted to determine whether the presence and degree of left ventricular diastolic dysfunction (LVDD) can be predicted by simple computed tomography (CT)-measured atrial diameter (CTLAD).Methods: Among adult patients who underwent both chest CT imaging echocardiography in emergency department from January 2020 December 2021, a retrospective cross-sectional enrolled whom time interval between two tests <24 hours. Receiver operating characteristic (ROC) curve...
A cardiothoracic ratio ≥0.50 is widely used as an indicator of cardiomegaly, but associations between the and left ventricular systolic dysfunction (LVSD) have not been investigated previously. We conducted this study to investigate relationship measured using computed tomography (CT) ejection fraction (LVEF), determine optimal for predicting (LVSD).A retrospective cross-sectional was performed data from patients who underwent both chest CT echocardiography at emergency department January 1...
Cerebrospinal fluid (CSF) examination is mandatory whenever central nervous system (CNS) infection suspected. However, pleocytosis not detected in a substantial number of suspected patients who undergo CSF examination. This study aimed to identify parameters that can aid predicting negative results (defined as white blood cell count <5 cells/high-power field).The included 101 neurologically intact underwent lumbar puncture because suspicion CNS infection. Patients were divided into and...
Patients suspected as having acute ischemic stroke usually undergo blood tests, including coagulation-related indexes, because thrombocytopenia and coagulopathy are contraindications for recombinant tissue plasminogen activator (rtPA) administration. We aimed to identify test indexes associated with symptomatic intracranial hemorrhage (sICH) in patients who received intravenous rtPA.This retrospective observational study included diagnosed were treated rtPA at the emergency department of a...
To investigate differences in the effect of intravenous (IV) thrombolysis regarding mismatch diffusion-weighted imaging-fluid-attenuated inversion recovery (DWI-FLAIR) among acute ischemic stroke patients who visited emergency department (ED) within 3 hours from onset symptoms.Among ED presenting with an between January 2011 and May 2013 at a tertiary hospital, those underwent magnetic resonance imaging before IV thrombolytic therapy were included this retrospective study. Patients divided...
We investigated whether counting inflation breaths out loud during cardiopulmonary resuscitation (CPR) led to an earlier resumption of chest compressions.In this randomised controlled manikin simulation study, conducted from February 2015 April 2015, 32 fourth-year Korean medical students, equally divided into study and control groups, performed 10 cycles 15:2 CPR while administering using a bag mask. The first participant counted the number loud, second was told perform compressions as soon...
The purpose of this study was to assess if a modified airway (MA), developed by the authors, would act as guide and improve performance intubation when used with video stylet (VS) or fiberoptic bronchoscope (FOB) for endotracheal intubation.This randomized crossover simulation using manikins conducted 36 novice operators. Time complete intubation, time see glottis, success rate each device were measured compared without use MA.For FOB MA, median significantly reduced from 46 31 seconds...
