Endobronchial Ultrasound: A New Technique of Pericardiocentesis in Posterior Loculated Pericardial Effusion.
Diagnostic and therapeutic pericardiocentesis is traditionally carried out via the transthoracic route under ultrasound or echocardiographic guidance. Posteriorly located loculated pericardial effusion cannot be safely drained using the standard subxiphoid or apical, intercostal approach. In the presence of clinically significant loculated effusion or effusion requiring diagnostic pericardiocentesis where an echocardiographic approach is not feasible, patients are usually referred for surgery. We here present a novel minimally invasive endobronchial ultrasound-guided approach for the aspiration of posteriorly loculated pericardial effusion that may obviate the need for surgery and its related complications.

The pathophysiological mechanisms by which mechanical ventilation can contribute to lung injury, termed "ventilator-induced lung injury" (VILI), is increasingly well understood. "Biotrauma" describes the release of mediators by injurious ventilatory strategies, which can lead to lung and distal organ injury. Insights from preclinical models demonstrating that traditional high tidal volumes drove the inflammatory response helped lead to clinical trials demonstrating lower mortality in patients who underwent ventilation with a lower-tidal-volume strategy. ⋯ This review examines the evolution of our understanding of the mechanisms underlying VILI, particularly regarding biotrauma. We will assess evidence that ventilatory and other "adjunctive" strategies that decrease biotrauma offer great potential to minimize the adverse consequences of VILI and to improve the outcomes of patients with respiratory failure.
