Is Intra-Articular Administration of Fibrinogen Effective in Postoperative Total Knee Arthroplasty Blood Loss? A Randomized Clinical Trial

Evaluating the Importance of Patient Blood Management During COVID-19 Pandemic

Due to the COVID-19 pandemic, the demand for blood products may decrease as the health care system shifts toward treating the increased number of patients afflicted with COVID-19 and delaying selective surgeries and emergency procedures. One of the most important problems for blood transfusion services during COVID-19 pandemic is the reduction in the number of donors and a decrease in blood stocks. This happens due to the limitations of attendance of donors in blood centers, lack of awareness, misinformation, fear of being infected while donating blood, and restricting the freedom of blood collection teams to attend public places. Blood transfusion services should be prepared and well-responded in a timely manner. In this regard, appropriate use of blood, diminishing unnecessary transfusions, and implementation of patient blood management (PBM) principles are considered as significant measurements. PBM can help maintain blood supply throughout the crisis and reduce the pressure on blood demand. As a result, blood products can be saved for patients who need it urgently. PBM focuses on the patient, as well as the conditions that make patients transfuse blood, such as blood loss, coagulopathy, platelet dysfunction, and anemia. Thus, the majority of health systems in different countries have made recommendations to the PBM in hospitals.

Clinical Applications of Aspirin as a Multi-potent Drug Beyond Cardiovascular Implications: A Proof of Concept for Anesthesiologists- A Narrative Review

To the best of our knowledge, aspirin (ASA) is known as a commonly used medication worldwide. Although the cardiovascular aspects of ASA are well-established, recently, it has been identified that ASA can yield multiple extra-cardiovascular therapeutic potencies in facing neurodegenerative disorders, various cancers, inflammatory responses, and the COVID-19 pandemic. In this review, we aimed to highlight the proven role of ASA administration in the variety of non-cardiovascular diseases, particularly in the field of anesthesiology.
