Continuous clonidine infusion: an alternative for children on mechanical ventilation.
This study aimed to assess the clonidine infusion rate in the first 6 h, as maintenance dose (first 24 h), and in the pre-extubation period (last 24 h), as well as the cumulative dose of other sedatives and the hemodynamic response. ⋯ Clonidine demonstrated to be a well-tolerated sedation option in pediatric patients submitted to mechanical ventilation, without relevant influence in hemodynamic variables.

Prognostic Value of T-wave Positivity in Lead aVR in COVID-19 Pneumonia.
T-wave positivity in the lead aVR is a marker of ventricular repolarization abnormality and provides information on short- and long-term cardiovascular mortality in heart failure patients, those with anterior myocardial infarction, and patients who underwent hemodialysis for various reasons. The aim of this study was to investigate the relationship between T-wave positivity in the lead aVR on superficial electrocardiogram and mortality from COVID-19 pneumonia. ⋯ A positive transcatheter aortic valve replacement is useful in risk stratification for mortality from COVID-19 pneumonia.
