Broad-scale adoption of spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs) into everyday practice has been slow, and uncertainty exists regarding what factors facilitate or impede their routine delivery. ⋯ There are a number of modifiable factors associated with SAT/SBT performance that are amenable to the development and testing of implementation interventions.

With an aging global population, the increased proportion of elderly patients in the intensive care unit (ICU) raises important questions regarding optimal management. Currently, data on tracheostomy and its outcomes in the elderly are limited. We aimed to determine the in-hospital survival of elderly ICU patients following tracheostomy, and describe impacts on discharge disposition and functional outcomes. ⋯ In patients aged ≥ 70 yr, tracheostomy during ICU stay marked a transition toward prolonged chronic critical illness. Nearly half of the patients died during the admission, and although a quarter were successfully decannulated, the majority of survivors were left with severe frailty and functional impairment.

Multicenter StudyManagement and outcomes of pregnant women admitted to intensive care unit for severe pneumonia related to SARS-CoV-2 infection: the multicenter and international COVIDPREG study.
Management and outcomes of pregnant women with coronavirus disease 2019 (COVID-19) admitted to intensive care unit (ICU) remain to be investigated. ⋯ In ICU, corticosteroids, tocilizumab and prone positioning were used in few pregnant women with COVID-19. Over a third of patients were intubated and delivery improved the driving pressure.

Tidal Volume-Dependent Activation of the Renin-Angiotensin System in Experimental Ventilator-Induced Lung Injury.
Ventilator-induced lung injury (VILI) is a major contributor to morbidity and mortality in critically ill patients. Mechanical damage to the lungs is potentially aggravated by the activation of the renin-angiotensin system (RAS). This article describes RAS activation profiles in VILI and discusses the effects of angiotensin (Ang) 1-7 supplementation or angiotensin-converting enzyme (ACE) inhibition with captopril as protective strategies. ⋯ VILI is accompanied by a strong activation of the RAS. Based on circulating Ang metabolite levels and tissue expression of RAS enzymes, classical ACE-dependent and alternative RAS cascades were activated in the HV T group, whereas classical RAS activation prevailed with VHV T ventilation. Ang 1-7 or captopril protected from VILI primarily by modifying the systemic RAS profile.

Communication with patients receiving mechanical ventilation in an intensive care unit can be challenging. Once a patient is tracheostomized, a speaking valve may enable restoration of verbal communication. To date, no data are available on the effect of speaking valves on communication success in intensive care units. ⋯ A speaking valve should be considered for patients with a tracheostomy as soon as possible to improve their communication success.
