Multicenter StudyChanges in heart rate, mean arterial pressure, and oxygen saturation after open and closed endotracheal suctioning: a prospective observational study.
It is widely assumed that closed suction systems (CSSs), as compared with open suction systems (OSSs), better guarantee optimal oxygenation with less disturbance of physiologic parameters in mechanically ventilated intensive care patients. We, therefore, quantified changes in heart rate (HR), mean arterial pressure (MAP), and peripheral oxygen saturation (Spo(2)) in patients undergoing endotracheal suctioning (ES) with CSS and OSS. ⋯ Changes in HR, MAP, and Spo(2) were comparable and mild during and after CSS and OSS. Both systems can be considered equally safe.

Multicenter StudyBarriers to feeding critically ill patients: a multicenter survey of critical care nurses.
The aims of this study were to describe the barriers to enterally feeding critically ill patients from a nursing perspective and to examine whether these barriers differ across centers. ⋯ Nurses in our multicenter survey identified important barriers to providing adequate enteral nutrition to their critically ill patients. The importance of these barriers does not appear to differ significantly across different clinical settings. Future research is required to evaluate if tailoring interventions to overcome these identified barriers is an effective strategy of improving nutrition practice.
