Multicenter Study Observational Study
Complete versus culprit-lesion-only percutaneous coronary intervention after out-of-hospital cardiac arrest in patients with multivessel disease.
Multivessel coronary artery disease (MVD) represents a common finding at invasive coronary angiography (ICA) among out-of-hospital cardiac arrest (OHCA) survivors. However, optimal invasive treatment strategy for MVD in OHCA remains unknown. Our study aims to assess if complete revascularization improves one-year clinical outcomes in these patients. ⋯ Our findings suggest that a complete percutaneous coronary revascularization strategy is associated with improved one-year survival rates in patients with MVD resuscitated from OHCA.

Randomized Controlled Trial
Selective or routine face mask application for breathing support of preterm infants at birth: a randomised trial.
Most preterm infants breathe spontaneously at birth. Despite this, the majority have a face mask immediately applied for breathing support. Face mask application may inhibit spontaneous breathing in newborn infants. We wished to determine whether selectively applying a mask to give positive pressure ventilation (PPV) for apnoea or bradycardia only compared to routinely applying a mask for continuous positive airway pressure (CPAP) resulted in fewer preterm infants receiving PPV in the delivery room (DR). ⋯ Selectively applying a face mask for PPV only did not result in fewer preterm infants receiving PPV in the DR.

Observational Study
Bystander Cardiopulmonary Resuscitation and Outcomes of Mass Cardiac Arrests Caused by A Crowd Crush.
A crowd crush can lead to respiratory arrest and result in multiple mass cardiac arrests (MCAs), which are often classified as Black Tag in disaster triage. Recently, many laypersons have been commonly trained in compression-only cardiopulmonary resuscitation (CPR) without ventilation support in various communities. This study aims to describe the characteristics of bystander CPR administered and the outcomes of MCAs during the Itaewon crowd crush incident. ⋯ Most MCAs were pronounced deceased, likely due to their classification as Black Tag or delayed response times. Only a small percentage (4.8%) of bystander CPR cases included rescue breathing. An optimized resuscitation protocol for MCAs in crowd crush scenarios should be developed.

The guidelines for Advanced Life Support issued by the European Resuscitation Council recommend considering drug delivery through intraosseous access if intravenous access to the vascular bed is not feasible or unsuccessful. Emergency prehospital intraosseous cannulation may theoretically lead to an increased risk of long-term complications such as osteomyelitis, osteonecrosis, or compartment syndrome. Such complications have previously been reported in case reports or small sample case series. We systematically investigated long-term complications potentially associated with intraosseous cannulation using validated Danish health registries. ⋯ Long-term complications such as osteomyelitis, osteonecrosis, or compartment syndrome following prehospital intraosseous cannulation and drug delivery occurred in less than 0.1% of the cases. Our findings indicate that prehospital intraosseous cannulation may be safe across age groups.

Observational Study
Visual detection of pulselessness by carotid artery sonography - A prospective observational study among medical students.
This cross-sectional study aimed to determine whether medical students with little to no ultrasound experience could correctly distinguish between 'pulsation present' and 'no pulsation present' after a short introductory video on the subject using ultrasound videos of the common carotid artery (CCA). ⋯ Medical students seem to be able to detect the absence of a pulse with a high degree of accuracy using 2D ultrasound of the CCA in a controlled study setting, using different ultrasound modes. The results of this study suggest that a combination of Color Doppler and B-mode may be useful when evaluating the CCA during CPR to answer the question 'pulsation present' or 'no pulsation present'.
