Transfusion

Despite evidence supporting the use of restrictive hemoglobin (Hb) transfusion triggers in critically ill patients, translation of this evidence into practice remains inconsistent. It was hypothesized that clinicians believe that longer-term ventilated patients require a higher Hb, particularly when ischemic heart disease coexists. ⋯ In response to scenarios, clinicians in the United Kingdom believe that a more liberal transfusion practice is required for patients failing weaning trials after 6 days of mechanical ventilation than the current evidence base supports.

Trauma patients are at risk of developing an acute coagulopathy of trauma (ACT) related to tissue injury, shock, and hemodilution. ACT is incompletely understood, but is similar to disseminated intravascular coagulation (DIC) and is associated with poor outcome. ⋯ Thrombin generation studies indicate that Trauma with ACT patients show dysregulated hemostasis characterized by excessive non-wound-related thrombin generation due to a combination of circulating procoagulants capable of activating coagulation systemically and reduced inhibitor levels allowing systemic thrombin generation to continue once started.

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.

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.
