Evidence-based fluid therapy is complicated by blurred boundaries toward other fields of therapy and the majority of trials not focusing on patient-relevant outcomes. Additionally, recent trials unsettled the faith in traditional concepts on fluid therapy. The article reviews the evidence on diagnosis and treatment of hypovolemia and discusses the use of balanced solutions and early goal-directed therapy (EGDT) in septic shock resuscitation. ⋯ Evidence-based fluid therapy includes a multifaceted diagnostic approach, the primary use of balanced crystalloids and early aggressive (septic) shock resuscitation.

ReviewManagement of direct oral anticoagulants-associated bleeding in the trauma patient.
This article emphasizes the differentiated management of direct oral anticoagulants (DOACs)-associated bleeding in trauma patients to generate a severity adjusted treatment protocol. ⋯ The different pharmacological properties of DOACs are important for the management of trauma-induced bleeding. Comorbidities like renal impairment and liver dysfunction prolong their half-life. Patients with minor bleeding in stable clinical condition can be managed by a 'wait and see' approach. Moderate bleeding is suggested to be managed by a primarily conservative approach. In life-threatening bleeding, the administration of activated or nonactivated factor concentrates seems justified, together with supportive measures as part of an advanced management protocol. The administration of specific antidotes may be an alternative in the future. A monoclonal antibody to dabigatran (idarucizumab) has recently been approved by the Food and Drug Administration, whereas antidotes to Factor X activated inhibitors (andexanet and aripazine) are still under development. Sufficiently powered studies with clinical and safety outcome measures are still missing for all specific antidotes at this time.

This article compares the strategy of a fixed transfusion ratio of plasma and platelet concentrates to red blood cells to reconstitute 'whole blood' with the concept of individualized goal-directed coagulation therapy (GDCT). ⋯ Individualized GDCT, guided by VET, offers several advantages over fixed ratio coagulation therapy. Studies comparing both hemostatic strategies are warranted.

Trauma-induced coagulopathy (TIC) is a multifactorial, global failure of the coagulation system to sustain adequate haemostasis after trauma haemorrhage. Damage control resuscitation is associated with improved outcomes although the mechanisms of how it corrects TIC have yet to be fully characterized. Identification of predominant pathophysiological pathways in TIC is required to develop effective treatment algorithms for trauma haemorrhage. ⋯ Further advances in TIC treatment require an enhanced understanding of the dynamic changes in the equilibrium between pro and anticoagulant factors, downstream effectors, and the host response. Delineating the interaction between fibrinolysis, fibrinogen utilization, platelet activity, and thrombin generation may provide opportunity for targeted intervention.

The average age of anesthesiologists in the USA is increasing. Advancing age is accompanied by challenges and opportunities to the individual anesthesiologist and his/her colleagues. This article will discuss the science behind policies to assure continued competence among these aging physicians and safety for their patients. ⋯ The average age of practicing anesthesiologists in the USA is increasing. As physicians continue to practice into later years, it is critical that innovative continuing medical education programs and objective evaluations of clinical skills and competence focused upon this group continue to be developed to assure public safety.
