ReviewAtelectasis and perioperative pulmonary complications in high-risk patients.
This review evaluates the link between perioperative lung atelectasis and postoperative pulmonary complications (PPCs) and how appropriate ventilatory strategies could mitigate this problem. ⋯ A goal-directed ventilatory approach keeping an 'open lung' condition during the perioperative period may reduce the incidence of PPCs.

ReviewStrategies to reduce the use of blood products: a European perspective.
Anemia is the most common hematologic problem preoperatively. In itself it compromises the outcome of surgical patients, and additionally results in more frequent allogeneic red blood cell (RBC) transfusions which again independently compromise patient outcome. In elective cardiac surgery as well as in other surgical specialties the use of a patient blood management program will minimize the exposure to blood products, lead to a cost reduction and improve patient's outcome. The aim of this review is to discuss the rationale for patient blood management, explain patient blood management in detail including modern and future transfusion strategies. ⋯ Patient blood management strategies are based on an interdisciplinary multimodal approach including early preoperative recognition and treatment of anemic patients, surgical efforts to minimize blood loss, optimal perfusion strategies to reduce hemodilution and continuous assessment of the bleeding and coagulation status of patients as well as a restrictive volume management. This allows specific and goal-directed treatment of patients, preventing anemia in elective patients, optimizing patient's coagulation status early, minimizing exposure to blood products, reducing costs and improving patient's outcome.

Bleeding in a perioperative setting occurs due to multiple causes, but newer anticoagulant and antiplatelet therapies are increasingly used preoperatively. As a result, patients often can present for surgery with underlying hemostatic disorders due to these acquired disorders or following major surgery or trauma. Because bleeding occurs due to multiple causes, the addition of pharmacologic agents creates an acquired defect that complicates the surgical injury and may result in increased blood loss. An understanding of hemostasis and therapeutic approaches, especially those in our current clinical settings, is crucial in managing these patients. ⋯ Nonsurgical bleeding in the operating room is the result of a multitude of factors including preoperative anticoagulants, dilution, fibrinolysis, and factor consumption. Therapeutic prohemostatic pharmacologic approaches, in addition to standard transfusion therapy, need to be considered in the prevention and treatment of coagulopathy in surgical patients.
