ReviewDissipation of energy during the respiratory cycle: conditional importance of ergotrauma to structural lung damage.
To describe and put into context recent conceptual advances regarding the relationship of energy load and power to ventilator-induced lung injury (VILI). ⋯ Although the unmodified values of machine-delivered energy or power (which are based on airway pressures and tidal volumes) cannot serve unconditionally as a rigid and quantitative guide to ventilator adjustment for lung protection, bedside consideration of the dynamics of ventilation and potential for ergotrauma represents a clear conceptual advance that complements the static parameters of the individual tidal cycle that with few exceptions have held our scientific attention.

To review epidemiology and pathophysiology of acute kidney injury (AKI) in trauma patients and propose strategies that aim at preventing AKI after trauma. ⋯ The high incidence of AKI in trauma patients should lead to early identification of those at risk of AKI to establish a resuscitation strategy that aims at preventing AKI.

Although nonoperative management (NOM) is the safest option in most patients with liver and splenic injuries or splenic injuries, some cases still need operative intervention. The aim of this review is to address the most recent literature and the evidence it provides for indications and timing of operative treatment for liver and spleen injuries. ⋯ Unstable patients with suspected ongoing bleeding from liver and spleen injuries or spleen injuries with inadequate effect of resuscitation should undergo immediate explorative laparotomy.More RCTs are needed to further determine the role of angiographic embolization and who can be safely be treated nonoperatively and who needs surgical intervention.

ReviewAcute life-threatening hypoxemia during mechanical ventilation.
To describe current evidence-based practice in the management of acute life-threatening hypoxemia in mechanically ventilated patients and some of the methods used to individualize the care of the patient. ⋯ Treating the patient with acute life-threatening hypoxemia during mechanical ventilation should begin with an evidence-based approach, with the goal of improving oxygenation and minimizing the harmful effects of mechanical ventilation. The use of advanced monitoring and the application of simple maneuvers at the bedside may assist clinicians to better individualize treatment and improve clinical outcomes.

Measurement of glomerular filtration rate is an essential tool for determining the health or dysfunction of the kidney. The glomerular filtration rate is a dynamic function that can change almost instantaneously in response to stressors. Despite its central role in nephrology, there are no techniques available to the clinician for monitoring glomerular filtration rate in real time. Recent advances in technology to measure fluorescent compounds through the skin are providing a new approach for real-time monitoring of glomerular filtration rate. This review frames these technologies within how such measurements might be used in clinical medicine. ⋯ These new technologies provide enhanced opportunities for diagnosis of kidney dysfunction and therapeutic monitoring. Accurate assessment of measured GFR will eliminate the erroneous diagnosis of chronic kidney disease (CKD) from many patients. Assessment of renal reserve will provide a new risk factor for progression of CKD. Real-time monitoring of GFR in critically ill patients will allow for earlier diagnosis of acute kidney injury and a dynamic metric to guide therapeutics. These are but a few of the many opportunities that this new technology will provide in both the clinical and research arenas.
