This study aimed to analyze the prognostic value of the presence of ST elevation in lead aVR [aVR(+)] in initial standard electrocardiogram (ECG) performed on admission in combination with clinical variables and Thrombolysis in Myocardial Infarction (TIMI) risk score for unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI). In 205 consecutive patients with UA/NSTEMI, we retrospectively evaluated admission ECG for aVR(+) of more than 0.5 mm. With the use of multivariate analysis, admission aVR(+) was found to be a strong and independent predictor of 30-day mortality. ⋯ In prespecified low-risk groups by clinical factors, those with aVR(+) had higher death rates than those without aVR(+): 16.1% vs 2.2% (P = .04), 13.9% vs 1.1% (P = .001), 12.4% vs 1.1% (P = .002), 9.6% vs 1.2% (P = .02), and 6.7% vs 0% (P = .05) for patients with negative troponin, heart rate of 110 beats per minute or less, systolic blood pressure greater than 90 mm Hg, Killip I class on admission, and age 70 years or younger, respectively. Patients with aVR(+) compared to patients without aVR(+) had higher death rates in the low- and intermediate-risk groups by TIMI risk score. Our findings suggest that aVR(+) has significant prognostic value in patients with UA/NSTEMI and may provide an additional prognostic value to the conventional cardiovascular risk factor, particularly in patients in the low-risk and intermediate-risk groups.

We hypothesize that not all of the traditional risk factors of impacting mortality rate in commonly traumatic populations with posttraumatic acute respiratory distress syndrome (ARDS) are independently associated with those patient populations identified with severe multiple trauma. Rather, we postulate that there may exist significantly different impacting degrees of specific risk factors in stratified patients (surviving beyond 24 and 96 hours)--more severe multiple trauma with higher injury score and long-term mechanical ventilation as well. ⋯ Impact of pulmonary contusion and Acute Physiology and Chronic Health Evaluation II score contributing to prediction of mortality may exist in the early phase after trauma. Sepsis is still a vital risk factor referring to systemic inflammatory response syndrome, infection, secondary multiple organ dysfunction, etc. Discharging trauma factors as early as possible becomes the critical therapeutic measure. Aspiration of gastric contents in emergency intensive care unit admission could lead to incremental mortality rate due to aspiration pneumonia. Long-standing mechanical ventilation should be constrained because it is likely to cause severe refractory complications.

This study aimed to assess the impact of different methods of draining nontraumatic hemopericardium on outcome from patients with out-of-hospital cardiac arrest (OHCA), identify independent predictors of return of spontaneous circulation (ROSC), and examine the ineffective rate of decompression based on subxiphoid pericardiotomy (SP) and percutaneous pericardial catheter drainage (PCD). ⋯ The early effective decompression method is associated with an increased rate of ROSC for OHCA patients with nontraumatic hemopericardium. Subxiphoid pericardiotomy has a better effective decompression of hemopericardium than PCD.

Emergency physicians attending to pediatric patients in acute care settings use electrocardiograms (ECGs) for a variety of reasons, including syncope, chest pain, ingestion, suspected dysrhythmias, and as part of the initial evaluation of suspected congenital heart disease. Thus, it is important for emergency and acute care providers to be familiar with the normal pediatric ECG in addition to common ECG abnormalities seen in the pediatric population. The purpose of this 3-part review will be to review (1) age-related changes in the pediatric ECG, (2) common arrhythmias encountered in the pediatric population, and (3) ECG indicators of structural and congenital heart disease in the pediatric population.

Each year there are over 7 million lacerations requiring wound closure in the emergency department. Traditionally, most lacerations have been closed with sutures. ⋯ As a result, new topical skin adhesives are expected to enter the market in the near future. This article will review the structure and function of cyanoacrylates as well as their advantages, indications, and usage.
