Randomized Controlled Trial Comparative Study
Airway scope vs Macintosh laryngoscope during chest compressions on a fresh cadaver model.
This study compared the Airway scope (AWS) to the Macintosh laryngoscope (ML) during chest compressions on a fresh cadaver. ⋯ Considering the lack of experience with the AWS, AWS could be an alternative intubation device during chest compressions after practices with AWS.

Maintenance of spontaneous effective ventilations can present unique challenges to emergency physicians directing procedural sedation in patients with underlying anatomic or physiologic upper airway pathology. In a morbidly obese patient requiring electrical cradioversion, use of bilevel positive airway pressure facilitated deep sedation while averting any adverse respiratory complications. Noninvasive pressure support ventilation may present another emergency department adjunct for difficult procedural sedation cases.

Case Reports
Postural hypotension as the initial presentation of fulminant right ventricular myocarditis.
Myocarditis can be totally asymptomatic or can manifest with chest pain syndromes, ranging from mild persistent chest pain of acute myopericarditis to severe symptoms that mimic acute myocardial infarction. About 60% of patients may have antecedent arthralgias, malaise, fevers, sweats, or chills consistent with viral infections 1 to 2 weeks before onset. Here, we report a postpartum young woman who developed postural hypotension as the first manifestation of fulminant myocarditis with initially acute "cold and dry" right-sided heart failure and cardiogenic shock. ⋯ Myocardial inflammation more frequently affects localized areas of the left ventricle free wall, rarely right ventricle (RV). However, predominant RV involvement with acute right-sided heart failure and low cardiac output syndrome can be easily overlooked due to lack of typical heart failure signs. On reviewing medical literatures, we had found no report regarding the RV involvement with acute right-sided heart failure as the initial presentation of fulminant myocarditis.

Randomized Controlled Trial
Phloroglucinol as an adjuvant analgesic to treat renal colic.
We tested whether the addition of phloroglucinol to piroxicam could improve pain relief in patients with acute renal colic visiting the emergency department. ⋯ There was no evidence that the addition of phloroglucinol improved the efficiency of piroxicam to relieve pain in acute renal colic.

Controlled Clinical Trial
Concordance between capnography and capnia in adults admitted for acute dyspnea in an ED.
End-tidal carbon dioxide pressure (etCO(2)) is widely used in anaesthesia and critical care in intubated patients. The aim of our preliminary study was to evaluate the feasibility of a simple device to predict capnia in spontaneously breathing patients in an emergency department (ED). ⋯ In our preliminary study, etCO(2) using a microstream method does not seem to accurately predict Paco(2) in patients presenting to an ED for acute dyspnea.
