Review Meta AnalysisProtocolized sedation effect on post-ICU posttraumatic stress disorder prevalence: A systematic review and network meta-analysis.
Strategies aiming light sedation are associated with decreased length on mechanical ventilation. However, awake or easily arousable patients may be prone to greater prevalence of posttraumatic stress disorder (PTSD). These systematic review and meta-analysis aimed to evaluate the safety of light sedation strategies regarding the prevalence of PTSD. ⋯ Light sedation strategies seem to be safe in terms of PTSD prevalence. However, the small number of included trials and patients may not be sufficient to drive strong statements.

ReviewVentilation and gas exchange management after cardiac arrest.
For several decades, physicians had integrated several interventions aiming to improve the outcomes in post-cardiac arrest patients. However, the mortality rate after cardiac arrest is still as high as 50%. Post-cardiac arrest syndrome is associated with high morbidity and mortality due to not only poor neurological outcome and cardiovascular failure but also respiratory dysfunction. ⋯ Furthermore, optimizing gas exchange by avoiding hypoxia and hyperoxia as well as maintaining normocarbia may improve neurological and survival outcome. Early multidisciplinary cardiac rehabilitation intervention is recommended. Minimally invasive monitoring techniques, that is, echocardiography, transpulmonary thermodilution method measuring extravascular lung water, as well as transcranial Doppler ultrasound, might be useful to improve appropriate management of post-cardiac arrest patients.

Mechanical ventilation is an important potentially modifiable risk factor for the development of bronchopulmonary dysplasia. Effective use of noninvasive respiratory support reduces the risk of lung injury. Lung volume recruitment and avoidance of excessive tidal volume are key elements of lung-protective ventilation strategies. Avoidance of oxidative stress, less invasive methods of surfactant administration, and high-frequency ventilation are also important factors in lung injury prevention.

Observational StudyTonic diaphragmatic activity in critically ill children with and without ventilatory support.
Infants have to actively maintain their end expiratory lung volume (EELV). In mechanically ventilated infants, the diaphragm stays activated until the end of expiration (tonic activity), contributing to EELV maintenance. It is unclear whether tonic activity compensates for the lack of laryngeal braking due to intubation or if it is normally present. ⋯ In infants, tonic EAdi remains involved in ventilatory control after extubation and restoration of laryngeal braking. Tonic EAdi may play a pathophysiological role in bronchiolitis and it can be reactivated in older patients. The interest of tonic EAdi as a tool to titrate mechanical ventilation warrants further evaluation.
