Guidelines for Transfusions
Guidelines for Transfu- sion Prepared by: Community Transfusion Committee Lincoln, Nebraska CHAIR: Aina Silenieks, MD MEMBERS: L. Bausch, M.D. R. Burton, M.D. S. Dunder, M.D. D. Voigt, M.D. B. J. Wilson, M.D. COMMUNITY Becky Croner REPRESENTATIVES: Ellen DiSalvo Christa Engel Phyllis Ericson Kelly Gillaspie Pat Gilles Vic Grdina Jessica Henrichs Kelly Jensen Laurel McReynolds Christina Nickel Angela Novotny Kelley Thiemann Janet Wachter Jodi Wikoff Guidelines For Transfusion Community Transfusion Committee INTRODUCTION The Community Transfusion Committee is a multidisciplinary group that meets to monitor blood utilization practices, establish guidelines for transfusion and discuss relevant transfusion related topics. It is comprised of physicians from local hospitals, invited guests, and community representatives from the hospitals’ transfusion services, nursing services, perfusion services, health information management, and the Nebraska Community Blood Bank. These Guidelines for Transfusion are reviewed and revised biannually by the Community Trans- fusion Committee to ensure that the industry’s most current practices are promoted. The Guidelines are the standard by which utilization practices are evaluated. They are also de- signed to provide helpful information to assist physicians to provide appropriate blood compo- nent therapy to patients. Appendices have been added for informational purposes and are not to be used as guidance for clinical decision making. ADULT RED CELLS A. Indications 1. One of the following a.

27. Clinical Indications for Cryoprecipitate And
27. CLINICAL INDICATIONS FOR CRYOPRECIPITATE AND FIBRINOGEN CONCENTRATE Cryoprecipitate is indicated in the treatment of fibrinogen deficiency or dysfibrinogenaemia.1 Fibrinogen concentrate is licenced for the treatment of acute bleeding episodes in patients with congenital fibrinogen deficiency, including afibrinogenaemia and hypofibrinogenaemia,2 and is currently funded under the National Blood Agreement. Key messages y Fibrinogen is an essential component of the coagulation system, due to its role in initial platelet aggregation and formation of a stable fibrin clot.3 y The decision to transfuse cryoprecipitate or fibrinogen concentrate to an individual patient should take into account the relative risks and benefits.3 y The routine use of cryoprecipitate or fibrinogen concentrate is not advised in medical or critically ill patients.2,4 y Cryoprecipitate or fibrinogen concentrate may be indicated in critical bleeding if fibrinogen levels are not maintained using FFP. In the setting of major obstetric haemorrhage, early administration of cryoprecipitate or fibrinogen concentrate may be necessary.3 Clinical implications y The routine use of cryoprecipitate or fibrinogen concentrate in medical or critically ill patients with coagulopathy is not advised. The underlying causes of coagulopathy should be identified; where transfusion is considered necessary, the risks and benefits should be considered for each patient. Specialist opinion is advised for the management of disseminated intravascular coagulopathy (MED-PP18, CC-PP7).2,4 y Cryoprecipitate or fibrinogen concentrate may be indicated in critical bleeding if fibrinogen levels are not maintained using FFP. In patients with critical bleeding requiring massive transfusion, suggested doses of blood components is 3-4g (CBMT-PP10)3 in adults or as per the local Massive Transfusion Protocol. -
Transfusion Service Introduction Blood/Blood Products Requests and Turnaround Time Expectations
Transfusion Service Introduction All blood products and blood components are supplied to UnityPoint Health-Meriter Hospital by the American Red Cross Blood Services. Pathology consultation is available regarding blood and/or components and dosages. ABO and Rho(D)—specific type is used whenever possible for leuko-poor packed cell transfusions. ABO-compatible blood is used for all plasma and platelet components whenever possible. For any orders involving HLA-matched components, the patient must have been HLA typed (sent to the American Red Cross) a minimum of 48 hours prior to intended infusion of the component. HLA typing is only required once. Blood components that are thawed, pooled, washed, volume-reduced, or deglycerolized for a patient will be charged to the patient even if not transfused. The charge is done because these components may not be suitable for another patient. Examples include: Autologous or directed donations Pooled cryoprecipitate 4-hour expiration Thawed fresh frozen plasma 24-hour expiration Thawed cryoprecipitate 6-hour expiration Deglycerolized red cells 24-hour expiration Washed red cells 24-hour expiration All blood components must be completely infused within 4 hours of release from UnityPoint Health-Meriter Laboratories Blood Bank, or be infused within the expiration time. Refer to UnityPoint Health -Meriter’s Blood and Blood Products Transfusion Policy #123 for additional information located on MyMeriter. Blood/Blood Products Requests and Turnaround Time Expectations Requests from UnityPoint Health-Meriter Hospital are entered in the hospital computer system and print in the UnityPoint Health- Meriter Laboratories Blood Bank. For the comfort of the patient, it is important to coordinate collection for other tests with Blood Bank specimens. -

We investigated associations between blood groups and circulating inflammation-related molecules in 3537 non-Hispanic white participants selected from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. Whole-genome scans were used to infer blood types for 12 common antigen systems based on well-characterized single-nucleotide polymorphisms. Serum levels of 96 biomarkers were measured on multiplex fluorescent bead-based panels. We estimated marker associations with blood type using weighted linear or logistic regression models adjusted for age, sex, smoking status, and principal components of p 1234567890();,: 1234567890();,: population substructure. Bonferroni correction was used to control for multiple comparisons, with two-sided values < 0.05 considered statistically significant. Among the 1152 associations tested, 10 were statistically significant. Duffy blood type was associated with levels of CXCL6/GCP2, CXCL5/ENA78, CCL11/EOTAXIN, CXCL1/GRO, CCL2/MCP1, CCL13/ MCP4, and CCL17/TARC, whereas ABO blood type was associated with levels of sVEGFR2, sVEGFR3, and sGP130. -
Section 8: Hematology CHAPTER 47: ANEMIA
Section 8: Hematology CHAPTER 47: ANEMIA Q.1. A 56-year-old man presents with symptoms of severe dyspnea on exertion and fatigue. His laboratory values are as follows: Hemoglobin 6.0 g/dL (normal: 12–15 g/dL) Hematocrit 18% (normal: 36%–46%) RBC count 2 million/L (normal: 4–5.2 million/L) Reticulocyte count 3% (normal: 0.5%–1.5%) Which of the following caused this man’s anemia? A. Decreased red cell production B. Increased red cell destruction C. Acute blood loss (hemorrhage) D. There is insufficient information to make a determination Answer: A. This man presents with anemia and an elevated reticulocyte count which seems to suggest a hemolytic process. His reticulocyte count, however, has not been corrected for the degree of anemia he displays. This can be done by calculating his corrected reticulocyte count ([3% × (18%/45%)] = 1.2%), which is less than 2 and thus suggestive of a hypoproliferative process (decreased red cell production). Q.2. A 25-year-old man with pancytopenia undergoes bone marrow aspiration and biopsy, which reveals profound hypocellularity and virtual absence of hematopoietic cells. Cytogenetic analysis of the bone marrow does not reveal any abnormalities. Despite red blood cell and platelet transfusions, his pancytopenia worsens. Histocompatibility testing of his only sister fails to reveal a match. What would be the most appropriate course of therapy? A. Antithymocyte globulin, cyclosporine, and prednisone B. Prednisone alone C. Supportive therapy with chronic blood and platelet transfusions only D. Methotrexate and prednisone E. Bone marrow transplant Answer: A. Although supportive care with transfusions is necessary for treating this patient with aplastic anemia, most cases are not self-limited. -

Fresh Frozen Plasma in General Practice
Practical guide to using frozen and fresh frozen plasma in general practice Why every practice should keep a bag in the freezer Kit Sturgess; MA; VetMB; PhD; CertVR; DSAM; CertVC; FRCVS RCVS Recognised Specialist in Small Animal Medicine Advanced Practitioner in Veterinary Cardiology Introduction Keeping stock at reasonable levels in a practice is vital to good business management balancing the need to have a product available against the costs of keeping stock that is not used and potentially may go out of date and need to be replaced (as well as subtle small costs of space, stock taking, disposal of out-of-date product etc.). Practices need, therefore, to make decisions about preparedness for ‘what if’ scenarios and have protocols in place. The difficult question for many practices is how bizarre/uncommon should these scenarios be to warrant keeping a drug or treatment in stock or buying a specialist piece of equipment. This can only really be answered on an individual practice basis as it will depend on the type of cases seen as well as the likely ability of clients to want to pay if the treatment/investigation is expensive and the relationship with other local practices in terms of borrowing treatments or using equipment. It is also important to try and understand the value that a particular drug or treatment will have on morbidity and mortality of a particular condition and whether the patient could be referred onwards if necessary so not having calcium available if presented with a seizuring hypocalcaemic patient would be a significant issue in that patient’s care. -

Patient's Guide to Blood Transfusions
Health Information For Patients and the Community A Patient’s Guide to Blood Transfusions Your doctor may order a blood transfusion as part of your therapy. This brochure will focus on frequently asked questions about blood products, transfusions, and the risks and benefits of the blood transfusion. PLEASE NOTE: This information is not intended to replace the medical advice of your doctor or health care provider and is intended for educational purposes only. Individual circumstances will affect your individual risks and benefits. Please discuss any questions or concerns with your doctor. What is a blood transfusion? A blood transfusion is donated blood given to patients with abnormal blood levels. The patient may have abnormal blood levels due to blood loss from trauma or surgery, or as a result of certain medical problems. The transfusion is done with one or more of the following parts of blood: red blood cells, platelets, plasma, or cryoprecipitate. What are the potential benefits of a blood transfusion? If your body does not have enough of one of the components of blood, you may develop serious life-threatening complications. • Red blood cells carry oxygen through your body to your heart and brain. Adequate oxygen is very important to maintain life. • Platelets and cryoprecipitate help to prevent or control bleeding. • Plasma replaces blood volume and also may help to prevent or control bleeding. How safe are blood transfusions? Blood donors are asked many questions about their health, behavior, and travel history in order to ensure that the blood supply is as safe as it can be. Only people who pass the survey are allowed to donate. -

Prolonged Partial Thromboplastin Time Without Bleeding History; Fletcher Factor Deficiency
Prolonged Partial Thromboplastin Time Without Bleeding History; Fletcher Factor Deficiency Celalettin ÜSTÜN*, Anand JILLELLA*, Linda HENDRIKS*, Mary JONAH**, Ferdane KUTLAR*, Russell BURGESS*, Abdullah KUTLAR* * Section of Hematology Oncology, Department of Medicine, Medical College of Georgia, ** Department of Pathology, Medical College of Georgia, Augusta, USA ABSTRACT A 67-year-old patient was admitted to the hospital to perform an esophagogastrectomy because a lesion at the lower esophagus was strongly suspicious for cancer. Her medical history and her family his- tory were negative for bleeding tendency or thrombosis. Her activated partial thromboplastin time (aPTT) was prolonged (44 s) whereas her prothrombin time (PT) was normal (11 s) presurgery. Mixing of her plasma with normal plasma corrected her prolonged aPTT (27.9 s). Prolonged incubation shortened the patient’s aPTT (36.3 s). Fletcher factor activity was found to be 50%. The patient underwent an esopha- gogastrectomy without bleeding complications under spinal anesthesia. Fletcher factor deficiency, a ra- re disorder, should be considered in patients who have no history of bleeding tendency with a prolonged aPTT. Surgical interventions are safe in these patients.
