Lung ultrasound score and diaphragm ultrasound in weaning from mechanical ventilation: are they different in patients with and without COVID-19?

Objective: To compare pre-extubation physiological characteristics and ultrasound variables between patients intubated for COVID-19 compared to a clinical population and those intubated for other reasons.

Methods: This was a secondary analysis of a prospective cohort study of patients undergoing invasive mechanical ventilation (IMV) for more than 48 h. Patients were divided into two groups: those intubated for COVID-19-induced ARDS and those intubated for other clinical reasons.

Impact of vertical positioning on lung aeration among mechanically ventilated intensive care unit patients: a randomized crossover clinical trial.

Objective: To assess the impact of different vertical positions on lung aeration in patients receiving invasive mechanical ventilation.

Methods: An open-label randomized crossover clinical trial was conducted between January and July 2020. Adults receiving invasive mechanical ventilation for > 24 hours and < 7 days with hemodynamic, respiratory and neurological stability were randomly assigned at a 1:1 ratio to the sitting position followed by passive orthostasis condition or the passive orthostasis followed by the sitting position condition.

Effectiveness and Safety of an Extended ICU Visitation Model for Delirium Prevention: A Before and After Study.

Objectives: To evaluate the effect of an extended visitation model compared with a restricted visitation model on the occurrence of delirium among ICU patients.

Design: Prospective single-center before and after study.

Setting: Thirty-one-bed medical-surgical ICU.
