We retrospectively analysed 30-day mortality and duration of intubation for 8016 children ventilated for three or more days, sedated with midazolam (n = 7716) or propofol (n = 300). We matched the propensity scores of 263 pairs of children. The propensity-matched 30-day mortality (95% CI) was similar: 17/263 (6.5%) with midazolam vs. 24/263 (9.1%) with propofol, p = 0.26. Weaning from mechanical ventilation of children sedated with midazolam was slower than weaning of children sedated with propofol, subhazard ratio (95% CI) 1.43 (1.18-1.73), p < 0.001.

ReviewDifferential Medical Aerosol Device and Interface Selection in Patients during Spontaneous, Conventional Mechanical and Noninvasive Ventilation.
Many aerosol delivery devices are available on the market that have different features, characteristics, and operating requirements that need to be considered for the effective treatment of patients with pulmonary diseases. Device selection in aerosol medicine is largely patient dependent. Since there is no aerosol device that suits all patient populations, device selection and successful integration of the prescribed aerosol device to patients is essential. This article explores key issues in differential device selection in spontaneously breathing adults with or without artificial airways, as well as critically ill patients receiving invasive and noninvasive ventilation, with discussion of considerations for integration of aerosol devices to each of these patient populations.

In mechanically ventilated (MV) cardiac arrest (CA) survivors admitted to the intensive care unit (ICU) avoidance of hypoxia is considered crucial. However, avoidance of hyperoxia may also be important. A conservative approach to oxygen therapy may reduce exposure to both. ⋯ Our findings provide preliminary support for the feasibility and physiological safety of conservative oxygen therapy in patients admitted to ICU for MV support after cardiac arrest (Trial registration, NCT01684124).

ReviewPositive and negative effects of mechanical ventilation on sleep in the ICU: a review with clinical recommendations.
Sleep is an essential physiologic process that helps to restore normal body homeostasis. Sleep disturbances have been shown to be associated with poor clinical outcomes, such as a greater risk of cardiovascular disease and increasing mortality. Critically ill patients, particularly those receiving mechanical ventilation, may be more susceptible to sleep disruption. ⋯ We provide recommendations for clinicians regarding optimal ventilatory settings and discuss fields for future research.

The abdominal compartment is separated from the thoracic compartment by the diaphragm. Under normal circumstances, a large portion of the venous return crosses the splanchnic and nonsplanchnic abdominal regions before entering the thorax and the right side of the heart. ⋯ It is important to understand the consequences of abdominal pressure changes on respiratory and circulatory physiology. This article elucidates important abdominal-respiratory-circulatory interactions and their clinical effects.
