Near-Apneic Ventilation Decreases Lung Injury and Fibroproliferation in an ARDS Model with ECMO.
There is wide variability in mechanical ventilation settings during extracorporeal membrane oxygenation (ECMO) in patients with acute respiratory distress syndrome. Although lung rest is recommended to prevent further injury, there is no evidence to support it. ⋯ In an acute respiratory distress syndrome model supported with ECMO, near-apneic ventilation decreased histologic lung injury and matrix metalloproteinase activity, and prevented the expression of myofibroblast markers.

Effects of Electrical Muscle Stimulation in Subjects Undergoing Prolonged Mechanical Ventilation.
Muscle atrophy and deconditioning are common complications in patients on prolonged mechanical ventilation (PMV). There are few studies that reviewed the effects of electrical muscle stimulation in this population. The purpose of this study was to examine the effects of electrical muscle stimulation on muscle function and hospitalization outcomes in subjects with PMV. ⋯ Electrical muscle stimulation enhanced muscle strength in subjects who received PMV. Electrical muscle stimulation can be considered a preventive strategy for muscle weakness in patients who receive PMV. (ClinicalTrials.gov registration NCT02227810.).

Renal Function, Weaning, and Survival in Patients With Ventilator-Dependent Respiratory Failure.
Acute kidney injury in acute critical illness has been associated with poor weaning and survival outcomes. The relation between renal dysfunction as defined by creatinine clearance (CrCl) and weaning from prolonged mechanical ventilation (PMV) is not known. The objective of this study was to determine the relation of measured CrCl to weaning and survival in patients on PMV. ⋯ Measured CrCl has a significant relation to successful weaning and survival in patients on PMV and may be useful in prognosticating their outcome.

Bronchopulmonary dysplasia (BPD) is a chronic inflammatory lung disease that affects thousands of newborns and infants every year. Although it is accepted that BPD results from lung damage and inflammation triggered by mechanical ventilation and hyperoxia, the causes and molecular events leading to lung damage and arrested development remain unknown. While recent advances in neonatal care have improved the survival of very low-weight infants, the rates of BPD have not improved accordingly. ⋯ However, the efficacy of these agents in preventing and ameliorating BPD symptoms varies depending on the populations studied and the disease stage. As the field moves towards personalised therapeutic approaches, this review summarises clinical and experimental studies conducted in various models, aiming to increase understanding of the cellular and molecular mechanisms by which these agents can prevent or treat BPD. Due to the increasing number of extremely premature infants, it is imperative that we continue to work towards understanding the mechanisms of BPD pathogenesis and generating more effective therapeutic options.

Lower respiratory tract infections in the intubated patient constitute a serious health problem due to their associated morbidity and mortality. Microaspiration of the buccopharyngeal secretions is the main physiopathological mechanism underlying the development of pneumonia and tracheobronchitis in intubated patients. All care bundles designed to prevent these infections include the use of antiseptics to reduce buccopharyngeal colonization. ⋯ However, 2meta-analyses have warned of a possible increase in mortality when chlorhexidine is used as an oral antiseptic. We therefore recommend its use but with extreme caution during application in order to avoid aspiration of the antiseptic.
