Dynamic arterial elastance obtained using arterial signal does not predict an increase in arterial pressure after a volume expansion in the operating room.
Dynamic arterial elastance (Eadyn) is defined as the ratio between pulse pressure variations (PPV) and stroke volume variations (SVV). Eadyn has been proposed to predict an increase in mean arterial pressure (MAP) after volume expansion with conflicting results. The aim of the present study was to test the reliability of Eadyn in hypotensive patients (MAP<65mmHg) in the operating room (OR). ⋯ In the present study performed in the OR and in hypotensive patients, Eadyn obtained using arterial signal was unable to predict an increase in MAP after volume expansion.

Randomized Controlled Trial Comparative StudyComparison of the McGrath® MAC video laryngoscope with direct Macintosh laryngoscopy for novice laryngoscopists in children without difficult intubation: A randomised controlled trial.
Airway management and tracheal intubation are routinely performed in paediatric anaesthesia and yet are associated with preventable adverse events. The McGrath® MAC is a video laryngoscope with a curved blade similar to the Macintosh blade, which has not been previously described in first intention paediatric tracheal intubation. We aimed to compare direct laryngoscopy to the McGrath® MAC video laryngoscope among novice laryngoscopists. ⋯ McGrath® MAC video laryngoscopy, when performed by a novice laryngoscopist on easy-to-intubate children, is associated with longer intubation times.

Rationale, study design and analysis plan of the lung imaging morphology for ventilator settings in acute respiratory distress syndrome study (LIVE study): Study protocol for a randomised controlled trial.
Different acute respiratory distress syndrome (ARDS) phenotypes may explain controversial results in clinical trials. Lung-morphology is one of the ARDS-phenotypes and physiological studies suggest different responses in terms of positive-end-expiratory-pressure (PEEP) and recruitment-manoeuvres (RM) according to loss of aeration. To evaluate whether tailored ventilator regimens may impact ARDS outcomes, our group has designed a randomised-clinical-trial of ventilator settings according to lung morphology in moderate-to-severe ARDS (LIVE study).
