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.

Coagulopathy represents one of the major challenges in the management of the severely injured patient. The present review will attempt to define the current 'optimal' transfusion strategies for the coagulopathic trauma patient and to assess potential weaknesses in the pertinent literature. ⋯ Coagulopathy has a significant impact on survival after major trauma. Most recent publications in the field are of retrospective design, and thus do not allow definitive recommendations for clinical practice. Well designed prospective trials and improved basic research studies are required to improve this important aspect of trauma care.

ReviewCoagulopathy in trauma patients: importance of thrombocyte function?
Trauma-induced coagulopathy results from a complex interplay between shock resuscitation and impaired clotting protease function. A pathophysiological role of platelets in this condition remains as yet undefined. This review examines our current knowledge of platelet function in haemostasis, possible mechanisms for aberrant activity in trauma and the role of platelet transfusions in exsanguinating haemorrhage. ⋯ Platelets undoubtedly play a pivotal role in haemostasis and trauma-induced coagulopathy. However, their specific dysfunction in trauma remains to be elucidated. Further research to characterize the dysfunctional pathways of the platelet response is required, together with clinical trials of the optimal timing and dose of platelet transfusions.

ReviewImproving safety in the operating room: a systematic literature review of retained surgical sponges.
Gossypibomas are surgical sponges that are unintentionally left inside a patient during a surgical procedure. To improve this patient safety indicator, anesthesiologists will need to work with operating room personnel. This study's goal was to systematically review the literature on retained sponges to identify body location, time to discovery, methods for detection, and risk factors. ⋯ More is being discovered about the patterns leading to a retained sponge. Multidisciplinary approaches and new technologies may help reduce this low frequency but clinically significant event. However, given the complexity of surgical care, eliminating retained sponges may prove elusive.
