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.

Methods: One hundred sixty patients with minor blunt thoracic trauma were evaluated first by chest radiograph and subsequently with a double-acquisition nonenhanced chest CT protocol: reference CT and ultralow-dose CT with iterative reconstruction. Two study radiologists independently assessed injuries with a structured report and subjective image quality and calculated certainty of diagnostic confidence level.

Pocket-sized ultrasound device for internal jugular puncture: A randomized study of performance on a simulation model.

Introduction: The aims of our study were to compare the performance of experienced emergency physicians for internal jugular vein puncture using a conventional ultrasound device versus a pocket-sized ultrasound in a training model.

Methods: In this single-center, prospective, randomized study, emergency physicians performed one puncture with each device in a randomized order. No emergency physicians used a pocket-sized ultrasound for central vascular catheter insertion in clinical practice.

A New Echocardiographic Tool for Cardiac Output Evaluation: An Experimental Study.

Background: The correlation between cardiac output (CO) evaluated by echocardiography and CO measured by thermodilution (COth) varies according to different studies. A new transthoracic echocardiography (TTE) tool allows automatic calculation of the subaortic velocity time index (VTIauto) and CO (COauto). The main objective was to evaluate the correlation between COth and COauto in an anesthetized, ventilated piglet hemorrhagic shock (HS) model.

Compression with a pocket-sized ultrasound device to diagnose proximal deep vein thrombosis.

Introduction: Compression ultrasonography (CUS) is a validated technique for the diagnosis of deep venous thrombosis (DVT), but has never been studied with pocket-sized ultrasound device (PUD). The main objective of this study was to assess the diagnostic performance of CUS made by emergency physicians (EPs) using a PUD.

Materials: This was a prospective, diagnostic test assessment, single-center study.

Assessment of five different probes for lung ultrasound in critically ill patients: A pilot study.

Introduction: 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.

Materials: This prospective, observational, pilot study involved 10 acute patients in whom a thoracic CT scan was performed. An expert performed an LUS reference exam using five different probes: three probes with a high-quality conventional echo machine (cardiac phased-array probe, abdominal convex probe, linear probe) and two probes (cardiac and linear) with a pocket ultrasound device (PUD).

Integration of lung ultrasound in the diagnostic reasoning in acute dyspneic patients: A prospective randomized study.

Introduction: Misdiagnosis in acute dyspneic patients (ADP) has consequences on their outcome. Lung ultrasound (LUS) is an accurate tool to improve diagnostic performance. The main goal of this study was to assess the determinants of increased diagnostic accuracy using LUS.

Tracheal extubation with suction vs. positive pressure during emergence from general anaesthesia in adults: A randomised controlled trial.

Background: After general anaesthesia (GA) in adults, the optimal tracheal extubation technique (positive pressure or suctioning) remains debated. The primary endpoint of this study was to assess the effects of these techniques on onset time of desaturation (SpO<92%).

Methods: Sixty-nine patients with a body mass index<30 scheduled for elective orthopaedic surgery were allocated to positive pressure (PP) or suctioning (SUC) group.

Changes in the availability of bedside ultrasound practice in emergency rooms and prehospital settings in France.

Objective: Ensuring the availability of ultrasound devices is the initial step in implementing clinical ultrasound (CUS) in emergency services. In France in 2011, 52% of emergency departments (EDs) and only 9% of mobile intensive care stations (MICS) were equipped with ultrasound devices. The main goal of this study was to determine the movement of these rates since 2011.
