6 december 2021 (Monday) - Consent for Transfusion ?

I did my “Consent for Transfusion” e-learning today. From my perspective it was somewhat academic; I just provide the blood that the clinical staff ask me for, but it made me think…

Obviously it is important that people should be aware of what treatment they get when in hospital, but are most people *really* able to form a considered opinion as to whether or not a blood transfusion is in their best interests? I really worry that most patients would value the opinion of “Karen from Facebook” over any professionally produced information with which they might be provided. 

And I must admit to a sly smile when I read the bit about telling patients that they have been given a transfusion when they were not in a position to know that they were receiving one. My father found out about his blood transfusion purely by accident… Should I put in a formal complaint with the hospital in question?

3 December 2021 (Friday) - -Parasitology Competency Assessment

I did my parasitology competence review today... I got nine out of ten right.  I missed the P. malariae but the slide in which that parasite was lurking wasn't a good film... in fact it was rather old and the parasites were somewhat squafty (to coin a phrase).

On reviewing that film I saw what I'd missed. I’d not actually missed them; I’d thought they were large mis-shapen and deformed platelets. But this is CPD... I have spotted where I am weak. I need to beef up my awareness of  P. malariae

2 December 2021 (Thursday) - Transfusion News Update

The nice people at Transfusion News sent their update today. Three articles… I wish I could get my head round weak D and D variants…

 Daprodustat is Noninferior to Erythropoiesis-Stimulating Agents for Patients with Chronic Kidney Disease Undergoing Dialysis

According to the U.S. CDC, about 37 million adults in the United States have chronic kidney disease (CKD). As CKD progresses, many patients require dialysis and develop anemia, which is usually treated with blood transfusions, erythropoiesis-stimulating agents (ESAs), and intravenous iron. Previous clinical trials have linked ESA use, however, to increased risk of stroke, myocardial infarction, thrombosis, and even death when targeting a normal hemoglobin level (i.e., 13.0 to 14.0 g/dL).

X- and Gamma-Irradiation Impact Red Blood Cells Similarly

Transfusion-associated graft versus host disease (TA-GVHD) is a rare complication that occurs when histoincompatible viable lymphocytes are transfused into an immunocompromised individual. The transfused lymphocytes recognize the recipient as foreign and mount an almost universally fatal immunological response. Leukoreduction filters are not completely effective at eliminating TA-GVHD; therefore, red blood cell components are irradiated to prevent TA-GVHD. [Register Now]
