Early results of ultra-low-dose CT-scan for extremity traumas in emergency room.

Background: Ultra-low dose computed tomography (ULD-CT) was shown to be a good alternative to digital radiographs in various locations. This study aimed to assess the diagnostic sensitivity and specificity of ULD-CT versus digital radiographs in patients consulting for extremity traumas in emergency room.

Methods: Digital radiography and ULD-CT scan were performed in patients consulting at the emergency department (February-August 2018) for extremity traumas.

Magnetic needle-tracking device for ultrasound guidance of radial artery puncture: A randomized study on a simulation model.

Introduction: Ultrasound-guidance of radial artery catheter insertion improves the first attempt success and reduces the occurrence of hematomas. Needle-tracking devices optimize needle-ultrasound beam alignment by displaying in real-time the needle tip position. We compared the median time need by experienced physicians to achieve radial artery puncture using either a conventional ultrasonography device (CUD) or a magnetic needle-tracking ultrasound device (MUD) in a simulation training arm model.

Diaphragmatic excursion measurement in emergency department patients with acute dyspnea to predict mechanical ventilation use.

Introduction: Ultrasound is a feasible and reproducible method for measuring right diaphragmatic excursion (RDE) in ED patients with acute dyspnea (AD). In AD patients, the correlation between the RDE value and the need for mechanical ventilation (MV) is not known.

Materials: This was a bicentric, observational prospective study.

Global longitudinal strain changes during hemorrhagic shock: An experimental study.

Objectives: Global longitudinal strain (GLS) appears sensitive and reproducible to identify left ventricular systolic dysfunction. The main objective was to analyze the GLS changes in an anesthetized-piglet model of controlled hemorrhagic shock (HS). The secondary objective was to evaluate if GLS changes was different depending on the expansion fluid treatment with or without norepinephrine.
