Prospective development and validation of a universal classification for paediatric videolaryngoscopic tracheal intubation: the PeDiAC score.

Background: The VIDIAC score, a prospectively developed universal classification for videolaryngoscopy, has shown excellent diagnostic performance in adults. However, there is no reliable classification system for videolaryngoscopic tracheal intubation in children. We aimed to develop and validate a multivariable logistic regression model and easy-to-use score to classify difficult videolaryngoscopic tracheal intubation in children and to compare it with the Cormack and Lehane classification.

Universal paediatric videolaryngoscopy and glottic view grading: a prospective observational study.

Background: Although videolaryngoscopy has been proposed as a default technique for tracheal intubation in children, published evidence on universal videolaryngoscopy implementation programmes is scarce. We aimed to determine if universal, first-choice videolaryngoscopy reduces the incidence of restricted glottic views and to determine the diagnostic performance of the Cormack and Lehane classification to discriminate between easy and difficult videolaryngoscopic tracheal intubations in children.

Methods: We conducted a prospective observational study within a structured universal videolaryngoscopy implementation programme.

Tpeak-Tend interval and Tpeak-Tend/QT ratio in patients with Brugada syndrome.

Aims: Brugada syndrome (BrS) is characterized by a typical electrocardiogram (ECG) pattern in right precordial leads (V1-V3; so-called type 1 ECG) and an increased risk of sudden cardiac death due to ventricular fibrillation. Annual cardiac event rates vary from 0.5% in asymptomatic to 7.
