Society of Cardiovascular Anesthesiologists Clinical Practice Improvement Advisory for Management of Perioperative Bleeding and Hemostasis in Cardiac Surgery Patients.

Bleeding after cardiac surgery is a common and serious complication leading to transfusion of multiple blood products and resulting in increased morbidity and mortality. Despite the publication of numerous guidelines and consensus statements for patient blood management in cardiac surgery, research has revealed that adherence to these guidelines is poor, and as a result, a significant variability in patient transfusion practices among practitioners still remains. In addition, although utilization of point-of-care (POC) coagulation monitors and the use of novel therapeutic strategies for perioperative hemostasis, such as the use of coagulation factor concentrates, have increased significantly over the last decade, they are still not widely available in every institution. Therefore, despite continuous efforts, blood transfusion in cardiac surgery has only modestly declined over the last decade, remaining at ≥50% in high-risk patients. Given these limitations, and in response to new regulatory and legislature requirements, the Society of Cardiovascular Anesthesiologists (SCA) has formed the Blood Conservation in Cardiac Surgery Working Group to organize, summarize, and disseminate the available best-practice knowledge in patient blood management in cardiac surgery. The current publication includes the summary statements and algorithms designed by the working group, after collection and review of the existing guidelines, consensus statements, and recommendations for patient blood management practices in cardiac surgery patients. The overall goal is creating a dynamic resource of easily accessible educational material that will help to increase and improve compliance with the existing evidence-based best practices of patient blood management by cardiac surgery care teams.

Techniques and applications of perioperative therapeutic plasma exchange.

PURPOSE OF REVIEW: Therapeutic plasma exchange (TPE) is a useful adjunct in the management of antibody-mediated disorders. The indications for TPE now include the perioperative setting. This review updates the anesthesiologist on the relevant clinical indications and precautions of plasma exchange. RECENT FINDINGS: Although still considered experimental, TPE for heparin-induced thrombocytopenia for urgent cardiac surgery is the most promising recent advance. SUMMARY: Plasmapheresis, or TPE, removes monoclonal antibodies, immune complexes and paraproteins. The utility of TPE in the perioperative period has recently become more apparent. Antibody-mediated disorders are associated with postoperative morbidity and mortality and are treated with TPE. Indications for TPE for cardiac surgery include heparin-induced thrombocytopenia, thrombotic thrombocytopenia purpura and antiphospholipid syndrome. Other indications for perioperative TPE are typically related to immunomodulation during solid-organ transplant. Immunomodulation, primarily with immunosuppressive medications and TPE, of a previously allosensitized recipient pretransplant increases the likelihood of a successful match. TPE is also useful in the management of intentional and inadvertent ABO incompatible recipients and is essential in the treatment of hyperacute rejection. TPE will likely be more utilized in the future and understanding the essentials of the procedure will facilitate the perioperative management of antibody-mediated disorders.

Anesthesia for tracheal reconstruction and transplantation.

PURPOSE OF REVIEW: Tracheobronchial lesions requiring significant resection of the airway have limited surgical options and present significant obstacles to the anesthesiologist and surgeon. This article will review recent advancements in anesthetic and surgical management. RECENT FINDINGS: Technological advances have introduced novel approaches to the patient with large airway lesions. The use of pump-driven and pumpless extracorporeal life support has rapidly expanded and allow for prolonged periods of apneic airway surgery. Tracheal transplantation has advanced from the cadaveric decellularized scaffolds initially used to true synthetic based structures with autologous stem cell derived epithelium. SUMMARY: Significant leaps in tissue engineered airway transplantation have created curative options for patients previously considered inoperable. These patients pose significant challenges to the anesthesiologist during the entire perioperative period. Close collaboration with surgeons and intensivists and the use of recently developed systems for extracorporeal life support are required.
