Randomized Controlled Trial
Pain management of acute limb trauma patients with intravenous lidocaine in emergency department.
This study was designed to assess the possible superiority of intravenous lidocaine to morphine for pain management. ⋯ The reduction in pain score using IV lidocaine is not superior to IV morphine in adult ED patients with traumatic limb pain.

Review Meta Analysis
Ketamine versus ketamine pluses atropine for pediatric sedation: A meta-analysis.
The application of atropine for pediatric sedation in the emergency department remains controversial. Our objective was to perform a comprehensive review of the literature and assess the clinical indexes in groups with and without atropine use. ⋯ Based on the current evidence, the group receiving atropine had reduced hypersalivation and increased rash and tachycardia; no differences were observed in nausea, vomiting, desaturation, agitation and laryngospasm between the two groups. Given that some of the studies were of low quality, additional high-quality randomized controlled trials should be conducted to further verify these findings.

Observational Study
Assessment of five different probes for lung ultrasound in critically ill patients: A pilot study.
The present study was aimed at comparing the diagnosis concordance of five echo probes of lung ultrasound (LUS) with CT scans in intensive care and emergency patients with acute respiratory failure. ⋯ Among the probes tested for LUS in acute patients, the cardiac probe of conventional machines and the linear probes of PUDs provide good diagnosis concordance with CT scans when performed by an expert and trained physician, but not by residents.

Contrast-enhanced ultrasound (CEUS) using intravascular microbubbles has potential to revolutionize point-of-care ultrasonography by expanding the use of ultrasonography into clinical scenarios previously reserved for computed tomography (CT), magnetic resonance imaging, or angiography. ⋯ CEUS is a promising imaging technique for point-of-care applications in pediatric and adult patients and can be applied for patients with allergy to CT contrast medium or with impaired renal function. More high-quality CEUS research focusing on accuracy, patient safety, health care costs, and throughput times is needed to validate its use in emergency and critical care settings.
