Multicenter Study Clinical TrialDiastolic function in neonates after the arterial switch operation: effects of positive pressure ventilation and inspiratory time.
To determine the effects positive pressure ventilation have on left ventricular diastolic function in neonates after the arterial switch operation. ⋯ In neonates with transposition of the great arteries (TGA) after the arterial switch operation, positive pressure ventilation augments left ventricular filling during the early phase of inspiration. Prolonging the inspiratory time over three cardiac cycles results in a reduction in left ventricular filling during the third diastolic period. There were no changes in the other diastolic indexes that reflect changes in ventricular compliance or relaxation.

Multicenter StudyA profile of European intensive care unit physiotherapists. European Society of Intensive Care Medicine.
To determine the profile and role of the physiotherapist in European intensive care units (ICUs). ⋯ Even though the response rate was limited, variations in the role and profile of the ICU physiotherapist are apparent across Europe. The involvement of physiotherapists in more specialized techniques is also a function of the number of physiotherapists working exclusively in an ICU.

Association of PEEP with two different inflation volumes in ARDS patients: effects on passive lung deflation and alveolar recruitment.
To assess the effects of the association of positive end-expiratory pressure (PEEP) with different inflation volumes (V(T)'s) on passive lung deflation and alveolar recruitment in ARDS patients. ⋯ In mechanically ventilated ARDS patients: (a) the behavior of airway resistance seems to depend on the degree of the prevailing lung distension; (b) alveolar recruitment appears to be more important when higher tidal volumes are used during mechanical ventilation on PEEP; (c) PEEP changes the mechanical properties of the respiratory system fast-emptying compartment.

Randomized Controlled Trial Clinical TrialParenteral with enteral nutrition in the critically ill.
To determine whether nutrient intake by early enteral nutrition with parenteral nutrition improves levels of retinol-binding protein and prealbumin (primary endpoint) and reduce morbidity and mortality (secondary endpoint) in ICU patients. ⋯ Although it enhances nutrient intake and corrects nutritional parameters such as RBP and prealbumin more rapidly, within 1 week, supplemental parenteral nutrition has no clinically relevant effect on outcome in ICU patients at the early phase of nutritional support.
