Randomized Controlled Trial
Comparison of intravascular access methods applied by nurses wearing personal protective equipment in simulated COVID-19 resuscitation: A randomized crossover simulation trial.
Prehospital emergency care of children is challenging. In the era of the COVID-19 pandemic, when medical personnel should use personal protective equipment against aerosol-generating procedures, the efficiency of medical procedures may decrease. The study objective was to evaluate the effectiveness of different intravascular access methods applied by nurses wearing biosafety Level-2 suits in simulated paediatric COVID-19 resuscitation. ⋯ The study provides evidence that nurses wearing biosafety Level-2 suits were able to obtain intraosseous access faster and more effectively as compared with IV access during simulated COVID-19 paediatric resuscitation. The most effective method of intravascular access was the NIO-P intraosseous device. Further clinical trials are necessary to confirm the results.

Multicenter Study Observational Study
Pneumothorax diagnosis with lung sliding quantification by speckle tracking: A prospective multicentric observational study.
Lung ultrasound is commonly used for the diagnosis of pneumothorax. However, recognition of pleural sliding is subjective and can be difficult for novice. The primary objective was to compare a novices physician's performance in diagnosing pneumothorax from ultrasound (US) scans either with visual evaluation or with maximum longitudinal pleural strain (MLPS). The secondary objective was to compare the diagnostic relevance of US with visual evaluation or MLPS to diagnose pneumothorax with an intermediately experienced and an expert physician. ⋯ In our study, speckle tracking analysis improved the accuracy of US for the novice and the intermediate but not the expert sonographer in the diagnosis of pneumothorax.
