[Management of critically ill patients in the resuscitation room : Different than for trauma?]
The general approach to the initial resuscitation of non-trauma patients does not differ from the ABCDE approach used to evaluate severely injured patients. After initial stabilization of vital functions patients are evaluated based on the symptoms and critical care interventions are initiated as and when necessary. ⋯ However, structured training programs similar to the advanced trauma life support (ATLS®)/European resuscitation course (ETC®) that go beyond the current scope of advanced cardiac life support training are needed. The development of an advanced critically ill life support (ACILS®) concept for non-trauma critically ill patients in the resuscitation room should be supported.

This article reviews the current diagnostic strategies for patients with suspected pulmonary embolism (PE) focusing on the current first choice imaging modality, computed tomographic pulmonary angiography (CTPA). Diagnostic strengths and weaknesses and associated cost-effectiveness of the diagnostic pathways will be discussed. The radiation dose risk of these pathways will be described and techniques to minimize dose will be reviewed. ⋯ Although current cost-effectiveness evaluations have established CT as integral in the PE diagnostic pathway, failure to acknowledge the impact of alternate diagnosis represents a current knowledge gap. The emerging dual energy capacity of current CT scanners offers the potential to evaluate both pulmonary vascular morphology and ventilation perfusion relationships within the lung parenchyma at high spatial resolution. This dual assessment of lung morphology and lung function at low (< 5 millisievert) radiation dose represents a substantial advance in PE imaging.

ReviewUpdate on minimally invasive hemodynamic monitoring in thoracic anesthesia.
Advanced hemodynamic monitoring is indispensable for adequate management of patients undergoing major surgery. This article will summarize minimally invasive hemodynamic monitoring technologies and their potential use in thoracic anesthesia. ⋯ Many different minimally invasive hemodynamic monitoring devices have been developed and clinically introduced in the last years. They offer the advantage of being less invasive and easier to use. However, these techniques have several limitations and data are scarce in patients undergoing thoracic anesthesia, preventing their widespread use so far.

Review[Update glutamine and antioxidants in critically ill patients].
Critical illness leads to oxidative stress and can induce or exacerbate nutrient deficiencies. This predisposes patients in the intensive care unit to impaired immune function and increased risk of developing infectious complications, organ dysfunction, and therefore worsens clinical outcome. ⋯ The following article summarizes the rationale and provides an update on recent clinical studies with special focus on the use of glutamine and antioxidants in critically ill patients. It further provides recommendations for the clinical use of these substrates in this particular patient population.

Sepsis Is Associated With Altered Cerebral Microcirculation and Tissue Hypoxia in Experimental Peritonitis.
Alterations in cerebral microvascular blood flow may develop during sepsis, but the consequences of these abnormalities on tissue oxygenation and metabolism are not well defined. We studied the evolution of microvascular blood flow, brain oxygen tension (PbO2), and metabolism in a clinically relevant animal model of septic shock. ⋯ Impaired cerebral microcirculation during sepsis is associated with progressive impairment in PbO2 and brain metabolism. Development of severe hypotension was responsible for a further increase in anaerobic metabolism. These alterations may play an important role in the pathogenesis of brain dysfunction during sepsis.
