ReviewRenal disease presenting as acute kidney injury: the diagnostic conundrum on the intensive care unit.
Acute kidney injury (AKI) is commonplace in most ICUs. In many cases the cause is believed to be multifactorial with sepsis being a major component. However, occasionally intrinsic renal disease will present to the ICU and as such critical care practitioners should be aware of this possibility and the ways in which such conditions may present. ⋯ Not all AKI as described by changes in creatinine and urine output which presents or develops on the ICU is the same. AKI is a syndrome which encompasses many conditions and as such is nondiagnostic. Clinicians, when faced with AKI should satisfy themselves as to the likely cause of the AKI.

To point out the tolerance of anemia, the possible use of alternatives to allogeneic blood products as well as the pathophysiological effects of transfusions in the context of multiple trauma patients. ⋯ Transfusion in trauma has to be an individual decision for a specific patient, not for a specific laboratory value. Transfusion management must aim at reducing or even avoiding the use of allogeneic blood products. This may lead to a new gold standard with cost reduction and amelioration of outcome of major trauma patients.

Although providing palliative care in the ICU has become a priority, the success of different methods to integrate palliative care into the ICU has varied. This review examines the current evidence supporting the different models of palliative care delivery and highlights areas for future study. ⋯ Developing a mixed model of palliative care delivery is necessary to meet the palliative care needs of critically ill patients. Efforts focused on improving integrative models and appropriately targeting the use of palliative care consultants are needed.

Mortality from trauma remains a global public health challenge, with most preventable deaths due to bleeding. The recognition of acute traumatic coagulopathy as a distinct clinical entity characterized by early coagulation dysfunction, arising prior to medical intervention, has revolutionized trauma management over the last decade. The aim of this article is to review our current understanding of acute traumatic coagulopathy. ⋯ Emphasis is now placed on early prevention, diagnosis, and aggressive initial treatment of coagulopathy and fibrinolysis with haemostatic blood products and tranexamic acid in addition to red cell units in order to reduce bleeding and improve clinical outcomes.

Securing the airway to provide sufficient oxygenation and ventilation is of paramount importance in the management of all types of emergency patients. Particularly in severely injured patients, strategies should be adapted according to useful recent literature findings. ⋯ An algorithm-based approach to airway management can prevent complications due to inadequate oxygenation or procedural difficulties in trauma patients; therefore, advanced equipment for handling a difficult airway is needed. After securing the airway, ventilation must be monitored by capnography, and normoventilation involving the early use of protective ventilation with low-tidal volume and moderate positive end-expiratory pressure must be the target. After early identification of patients with blunt chest trauma at risk for respiratory failure, noninvasive ventilation might be a treatment strategy, which should be evaluated in future research.
