Early point-of-care echocardiography as a predictive factor for absence of return of spontaneous circulatory in out-of-hospital cardiac arrests: A multicentre observational study.

Introduction: Early assessment of the prognosis of a patient in cardiac arrest during cardiopulmonary resuscitation is highly challenging. This study aims to evaluate the predictive outcome value of early point-of-care ultrasound (POCUS) in out-of-hospital settings.

Methods: This observational, prospective, multicentre study's primary endpoint was the positive predictive value (PPV) of POCUS cardiac standstill within the first 12 min of advanced life support (ALS) initiation in determining the absence of return of spontaneous circulation (ROSC).

Use of troponin assay after electrical injuries: a 15-year multicentre retrospective cohort in emergency departments.

Background: Patients with electrical injury are considered to be at risk of cardiac arrhythmia. Assessing the risk of developing a major adverse cardiac event (MACE) is the cornerstone of patient management. The aim of this study was to assess the performance of initial troponin and troponin rise to predict Major Adverse Cardiac Events (MACEs) in all patients with electrical injuries admitted to the Emergency Department.

Goal-directed ultrasound protocol in patients with nontraumatic undifferentiated shock in the emergency department: prospective dual centre study.

Background And Importance: Early identification of the cause of shock is associated with better prognosis.

Objective: The aim of this study was to explore the performances of an ultrasound protocol (echoSHOCK) to diagnose the cause of shock in the emergency department (ED).

Design, Settings And Participants: This was a prospective study performed in two EDs.
