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).

HIV status and lay bystander cardiopulmonary resuscitation initiation for witnessed cardiac arrest.

Introduction: Early initiation of cardiopulmonary resuscitation (CPR) by bystanders of out-of-hospital cardiac arrest (OHCA) significantly improves survival and neurological outcomes. However, misconceptions about human immunodeficiency virus (HIV) transmission risk during CPR can deter lay bystanders from performing resuscitation. The aim of this study was to compare the rate of CPR initiation by lay bystanders who witnessed OHCA in subjects with and without HIV infection.

Cumulative dose of epinephrine and mode of death after non-shockable out-of-hospital cardiac arrest: a registry-based study.

Background: Epinephrine increases the chances of return of spontaneous circulation (ROSC) in out-of-hospital cardiac arrest (OHCA), especially when the initial rhythm is non-shockable. However, this drug could also worsen the post-resuscitation syndrome (PRS). We assessed the association between epinephrine use during cardiopulmonary resuscitation (CPR) and subsequent intensive care unit (ICU) mortality in patients with ROSC after non-shockable OHCA.

Impact of an enhanced focused cardiac ultrasound on treatment changes in a population of internal medicine patients.

Background: Hospitalized patients with acute shortness of breath (SOB) could benefit from an enhanced focused cardiac ultrasound (eFoCUS) with Doppler measurements to reassess treatment and diagnosis.

Methods: This was a retrospective observational study performed in a medical ward. Included patients were those hospitalized for acute SOB.
