The year 2020 was a monumental year in medicine, and this review focuses on selected articles for cardiothoracic anesthesiologists and perioperative physicians involved in the care of heart and lung transplant patients. In the field of lung transplantation, significant strides were made in our knowledge of risk stratification during the preoperative assessment of potential recipients, perioperative transfusion medicine, and the administration of coagulation factor concentrates. In addition, variations in perioperative management and outcomes between institutions were studied across an assortment of metrics regarding lung transplantation, including case volumes and anesthetic practices. Transitioning to topics in the field of heart transplantation, consideration was given to recipients with adult congenital heart disease, and separately, approaches to expanding the donor pool through donation after circulatory death. With regard to preoperative support, outcomes for the total artificial heart as well as the MitraClip as bridges to transplantation were published.

SummaryA national multicentre study was performed to investigate the effects of donorselection and the use of heat-treated plasma products on seroconversion to HIV in 157 Dutch haemophiliacs. All patients included in the study were seronegative for HIV antibodies in 1983.Thirteen percent (20/157) seroconverted between 1983 and 1986. Nineteen of 20 seroconversions could be related to the use of non heat-treated products in the year preceding HIV antibody seroconversion. One seroconversion occurred in a person using heat-treated non donor screened product.Seroconversion rate decreased as a result of the policy to discourage high risk blood donors and no seroconversions were observed following the introduction of donor screening in 1985.

Haemostatic Resuscitation

Although platelets play a central role in haemostasis, the dynamics of platelet counts during haemostatic resuscitation, the response to platelet transfusion, and effects on clinical outcome are poorly described for trauma patients. As a sub-study of the already published randomized controlled RETIC Study “Reversal of Trauma-induced Coagulopathy using First-line Coagulation Factor Concentrates or Fresh-Frozen Plasma” trial, we here analysed whether the type of first-line haemostatic resuscitation influences the frequency of platelet transfusion and determined the effects of platelet transfusion in coagulopathic patients with major trauma. Patients randomly received first-line plasma (FFP) or coagulation factor concentrates (CFC), mainly fibrinogen concentrate. In both groups, platelets were transfused to maintain platelet counts between 50 and 100 × 109/L. Transfusion rates were significantly higher in the FFP (n = 44) vs. CFC (n = 50) group (FFP 47.7% vs. CFC 26%); p = 0.0335. Logistic regression analysis adjusted for the stratification variables injury severity score (ISS) and brain injury confirmed that first-line FFP therapy increases the odds for platelet transfusion (odds ratio (OR) 5.79 (1.89 to 20.62), p = 0.0036) and this effect was larger than a 16-point increase in ISS (OR 4.33 (2.17 to 9.74), p = 0.0001). In conclusion, early fibrinogen supplementation exerted a platelet-saving effect while platelet transfusions did not substantially improve platelet count and might contribute to poor clinical outcome.

SummaryGuidelines of official societies for diagnosis and therapy of intraoperatively occurring hypocoagulability rely mainly on data of patients receiving whole blood transfusions. They recommend -provided that laboratory evaluation shows deficiency (values >1.5 fold normal)- administration of fresh frozen plasma, cryoprecipitate and platelet concentrates (platelet count <50 000 or <100 000/μl). This article describes the pathogenesis of coagulopathy in the light of the special intraoperative setting, emphasizes recent changes of blood component preparation, transfusion triggers, effects of volume therapy and challenges standard laboratory assays as reliable guide for intraoperative hemostatic therapy. The role of thrombelastographic monitoring is discussed as well as an alternative strategy to compensate deficiencies by the use of coagulation factor concentrates instead of or in addition to transfusion of FFP, a new concept which is illustrated by the presentation of an actual case report.

Bleeding is common in acute myeloblastic leukaemia (From our experience with 30 children suffering from AML we drew the following conclusions: At the time of diagnosis, the danger of bleeding cannot be predicted by laboratory means. However, the following factors represent increased risks: Promyeloblastic leukaemia, high blast count, low fibrinogen, low plasminogen. From coagulation studies performed at the time of bleeding complications, the pathomechanism leading to bleeding complications usually cannot be detected. The question, whether inpairment of production, consumption coagulopathy, or primary fibrinolysis causes the bleeding complications can only to answered by controlling frequently clinical and haemostatic criteria, which include the thrombocytic system as well as plasmatic coagulation and fibrinolysis. At the present time, the therapy of bleeding complications in AML is symptomatic. It consists of transfusion with thromlocytes or fresh whole wood , respectively. Coagulation factor concentrates shouls only be given in combination with Heparin to prevent the deterioration of consumption coagulopathy.
