ReviewCoagulopathy in trauma patients: what are the main influence factors?
Coagulopathy and bleeding after severe injury is a common problem. Whenever caring for critically ill patients, clinicians must anticipate, recognize and manage the coagulopathy of trauma. When left untreated, cardiovascular shock and multiorgan system failure ensue. Uncompensated hemorrhage often culminates in death, highlighting the significance of recognizing the main influences in coagulopathy of trauma. ⋯ Although mortality previously was thought to be summarily independent of medical interventions and resuscitations, we now know the opposite to be true; it is our expectation and indeed our obligation to recognize and manage the coagulopathy of trauma better than in past years. In as much as we continue to prevent acidosis, hypothermia and the progressive coagulopathy following injury, trauma victims the world over are benefiting and surviving longer, living proof that demonstrates the utility of managing the coagulopathy of trauma.

ReviewTransfusion in trauma: why and how should we change our current practice?
Major trauma is often associated with hemorrhage and transfusion of blood and blood products, which are all associated with adverse clinical outcome. The aim of this review is to emphasize why bleeding and coagulation has to be monitored closely in trauma patients and to discuss the rationale behind modern and future transfusion strategies. ⋯ Future transfusion strategies are based on early and continuous assessment of the bleeding and coagulation status of trauma patients. This allows specific and goal-directed treatment, thereby optimizing the patient's coagulation status early, minimizing the patient's exposure to blood products, reducing costs and improving the patient's outcome.

ReviewThe role of recombinant-activated factor VII in bleeding trauma patients.
Exsanguinating hemorrhage and postshock organ failure account for 35-40% of deaths from trauma, and there is an increasing recognition of the importance of coagulopathy in the evolution of this disease. ⋯ We present a brief discussion of the mechanism of action of rFVIIa and its role in facilitating hemostasis and a review of the recent medical literature on the use of rFVIIa in trauma patients, including current guidelines and controversies.

ReviewCan anesthesia information management systems improve quality in the surgical suite?
To summarize developments related to the use of anesthesia information management systems (AIMS) and quality assurance and quality improvement. ⋯ Implementation of information technologies in anesthesia as well as in all aspects of healthcare redesigns how patients receive care. AIMS accurately measure, store, query, and recall vital sign data, and enable the systematic analysis of anesthesia-related perioperative data. Using AIMS, quality management programs will be able to study more incidents and analyze them more quickly. Ideally, decision-support systems with practice guidelines delivered via AIMS should help overcome the usual barriers to guideline adherence, and improve care and safety.

ReviewThe role of thromboelastometry and recombinant factor VIIa in trauma.
Recombinant factor VIIa (rFVIIa) and thromboelastography have acquired increasing importance in patients with severe bleeding and coagulopathy. This article reviews the current opinions regarding their use, with the purpose of clarifying the ambiguities that exist in dealing with trauma patients. ⋯ Thromboelastometry may guide the medical staff when and to whom rFVIIa could be administered. Evidence also encourages the use of rFVIIa in traumatic brain injury. More research is required to prove decreases in mortality using both thromboelastography and rFVIIa in trauma, with a focus on clear end points and goal-directed therapy.
