Randomized Controlled Trial Comparative Study
Endotrol-tracheal tube assisted endotracheal intubation during video laryngoscopy.
Video laryngoscopes allow indirect visualization of the glottis and provide superior views of the glottis compared to direct laryngoscopes in patients with both normal and difficult airways, but it may be difficult to advance the endotracheal tube (ETT) through the vocal cords into the trachea, unless a stylet is used. We propose that the Endotrol(®) ETT may be an effective tool to facilitate video laryngoscope-assisted orotracheal intubation without the use of a stylet. After obtaining written and oral informed consent, 60-adult patients scheduled for elective surgery requiring general anesthesia with orotracheal intubation were enrolled. ⋯ Three intubations using the Endotrol(®) were characterized as difficult, whereas there were no difficult intubations with the GlideRite(®)stylet. The Endotrol(®) ETT, as compared to a standard ETT with a non-malleable stylet, is associated with longer intubation times and a subjective increase in difficulty of use. It may, however, still be a clinically viable alternative in video laryngoscope-assisted orotracheal intubation when use of a rigid stylet is undesirable.

Comparative Study
Diagnostic accuracy and reproducibility of pleural and lung ultrasound in discriminating cardiogenic causes of acute dyspnea in the emergency department.
Dyspnea is a common symptom in patients admitted to the Emergency Department (ED), and discriminating between cardiogenic and non-cardiogenic dyspnea is often a clinical dilemma. The initial diagnostic work-up may be inaccurate in defining the etiology and the underlying pathophysiology. The aim of this study was to evaluate the diagnostic accuracy and reproducibility of pleural and lung ultrasound (PLUS), performed by emergency physicians at the time of a patient's initial evaluation in the ED, in identifying cardiac causes of acute dyspnea. ⋯ Agreement between experienced and inexperienced operators was 92.2% (p < 0.01) and 95% (p < 0.01) for diagnosis of AIS and pleural effusion, respectively. In early evaluation of patients presenting to the ED with dyspnea, PLUS, performed with the purpose of identifying diffuse AIS, may represent an accurate and reproducible bedside tool in discriminating between cardiogenic and non-cardiogenic dyspnea. On the contrary, US detection of pleural effusions does not allow reliable discrimination between different causes of acute dyspnea in unselected ED patients.

Patients in intensive care units (ICUs) frequently have multiple infections or persistent fever despite management. The aim of this study was to evaluate the diagnostic contribution of gallium-67 scintigraphy in ICU patients with suspected occult sepsis. One hundred and seventeen patients (>18 years) who had undergone gallium-67 scintigraphy in the ICU of our medical center over a 3-year period were retrospectively reviewed and analyzed. ⋯ Significant differences were not observed between patients with positive and negative findings on gallium-67 scintigraphy in characteristics, underlying diseases, laboratory data, and outcomes. Gallium-67 scintigraphy helped to detect new or additional infectious sites, particularly bone, joint, and soft tissues. However, differences in hospital stay and mortality were not observed between patients with positive and negative findings.

Since the development of coronary care units (CCUs), telemetry has rapidly become the standard of care in evaluating patients with suspected acute coronary syndromes, regardless of the probability for ischemia. However, there is no data to support this practice. Our objective was to evaluate the utility of routine cardiac monitoring in a chest pain observation unit. ⋯ Of the remaining 248 patients, no patient suffered a cardiac arrest, no patient was admitted to the hospital secondary to cardiac dysrhythmia, and no alteration in a patient's medical therapy was made secondary to cardiac dysrhythmia. No patient returned to the Emergency Department within 72 h with cardiac arrest, acute dysrhythmia or acute myocardial infarction. Although telemetry may be the standard of care in evaluating the patients with suspected acute coronary syndromes, regardless of the probability of an acute ischemic syndrome, in those patients with a normal or non diagnostic ECG and resolved symptoms, routine cardiac monitoring is unnecessary.
