Hemorrhage is a leading cause of potentially preventable death in both civilian and military trauma patients. Animal data have shown that hemostatic bandages reduce hemorrhage and improve survival. This article reports recent clinical observations regarding the efficacy and evolution of use of two new hemostatic bandages employed in the global war on terrorism. ⋯ Hemostatic agents stop or decrease bleeding. Whereas HemCon appears to be safe, QuikClot may produce superficial burns. These new hemostatic agents have a place in the surgical armamentarium to assist in controlling internal hemorrhage from truncal and pelvic hemorrhage, especially during damage-control surgery.

Randomized Controlled Trial Multicenter Study Controlled Clinical Trial
The treatment of bleeding is to stop the bleeding! Treatment of trauma-related hemorrhage.
The secret with any alternative to transfusion is to minimize the need for transfusion in the first place. This can be done by reducing the volume of blood loss. The volume of blood being lost can be reduced by direct methods where possible (i.e., hemostasis at the point of bleeding), or by improving the coagulation profile of the patient, thereby improving the extrinsic coagulation. Recombinant activated factor VII (rFVIIa) offers theoretical possibilities of improving the coagulation profile. ⋯ Treatment with adjunctive rFVIIa significantly reduces transfusion requirements in the 48 hours after severe injury and these procoagulant effects may improve clinical outcome at 30 days.

Randomized Controlled Trial Comparative Study
Large-dose intravenous ferric carboxymaltose injection for iron deficiency anemia in heavy uterine bleeding: a randomized, controlled trial.
The objective was to evaluate efficacy and safety of rapid, large-dose intravenous (IV) administration of ferric carboxymaltose compared to oral iron in correcting iron deficiency anemia due to heavy uterine bleeding. ⋯ In patients with iron deficiency anemia due to heavy uterine bleeding, rapid IV administration of large doses of a new iron agent, ferric carboxymaltose, is more effective than oral iron therapy in correcting anemia, replenishing iron stores, and improving quality of life.

Risks of transfusion-transmitted infections (TTIs), transfusion-associated sepsis (TAS), and transfusion-related acute lung injury (TRALI) were compared between pooled whole blood-derived (PWBD) and single-donor platelets (PLTs) transfused in the United States. ⋯ TTIs and TAS determine the relative safety of PWBD versus single-donor PLTs. The available limited data do not support a higher risk of TRALI from single-donor (compared with PWBD) PLTs.

Most cases of human babesiosis in North America are caused by Babesia microti, which is endemic in the northeastern and upper midwestern United States. Although the disease is usually transmitted by a tick bite, there has been an increase in the number of transfusion-transmitted cases reported. We describe a fatal case of transfusion-transmitted babesiosis in a nonendemic state, Delaware. ⋯ We believe that this is the first reported case of transfusion-transmitted babesiosis in Delaware, a nonendemic state. Our case illustrates that clinicians should consider babesiosis in the differential diagnosis of immunocompromised patients who have fever and recent transfusion history, even in areas where babesiosis is not endemic. It also demonstrates the need for better preventive strategies including more sensitive, specific, and rapid blood donor screening tests to prevent transfusion-transmitted babesiosis.
