This study demonstrates that the 2 hours accelerated protocol using high sensitivity Troponin assay at 0 and 2 hours with comprehensive clinical evaluation and ECG followed by stress testing might be successful in identifying low-risk patient population who may benefit from early discharge from ED reducing associated costs and length of stay.

Background:Shivering associated with spinal anesthesia is a common complication. It also causes more usage of oxygen, increased production of carbon dioxide (CO2), and lactic acidosis with movement of clots and bleeding after surgery. This study was performed to compare the different dosages of intrathecal meperidine and their effects on shivering during and after surgery and to compare these to the control group.Materials and Methods:This study is a clinical trial. Target population consisted of the patients who were candidates for lower limb orthopedic surgery under spinal anesthesia. About 120 patients were chosen and randomly divided into four groups. In group 1, spinal anesthesia was performed with 3 ml marcaine 0.5% and 0.1 mg/kg meperidine. In group 2, 3 ml marcaine 0.5% and 0.2 mg/kg meperidine was given. In group 3, 3 ml marcaine 0.5% and 0.3 mg/kg meperidine, and in the fourth group, 3 ml marcaine 0.5% and normal saline in the same volume were injected. During surgery and recovery, hemodynamic index and shivering were recorded.Results:Based on the analyzed data, in the fourth group 23 patients (76.7%) had shivering. While the prevalence of shivering in the first, second, and third groups was 15 patients (50%), 11 patients (36.7%), and 3 patients (10%), respectively. Chi-square test showed significant difference in the four groups (P < 0.001).Conclusions:Using higher dosage of intrathecal meperidine (0.3 mg/kg) was more effective than using lower dosage of meperidine (0.1 mg/kg and 0.2 mg/kg) in reducing the incidence and severity of shivering during spinal anesthesia in lower extremity orthopedic surgeries.

All hospitals had high rates of quality metric compliance and finished with similar overall AMI performance composite scores after 1 year.

For emergency department physicians, timely triage and risk stratification of chest pain patients remains a challenge. Faced with an aging population and the growing prevalence of heart disease, clinicians are seeking more effective ways to diagnose acute coronary syndromes rapidly and accurately. Emergency department physicians must make critical and time-sensitive decisions based on patient history, physical examination, and 12-lead electrocardiogram as justification for diagnosis of acute coronary syndromes. But because most of these tools are not reliable independently, these incomplete strategies can result in costly and inappropriate treatment decisions.

Tumor-like formation of thrombus in the right atrial cavity is rare. It may be mistaken for a myxoma. The exact pathophysiology of an isolated thrombus in the heart is still unclear. Management to prevent complications such as pulmonary thromboembolism depends on the clinical judgment of a cardiologist. This report describes a 76-year-old woman with right atrial thrombus causing subsequent pulmonary thromboembolism in right lung. She initially presented to us with pulmonary embolism, and later, an incidental finding of a mass in her right atrium revealed an association of thrombus in heart with thrombus in lung. The challenging management was to resect this thrombus which was fixed to atrial septum, and a trial of anticoagulation did not resolve it. Exact management of such incidental findings in right heart cavities is not well established. Some cases may benefit from resection of such formed fixed thrombus.
