A total of 135 obstetric patients who were first-time transfusion recipients at the University of Maiduguri Teaching Hospital were studied with respect to the incidence and clinical severity of urticarial transfusion reactions (UTR) in relation to the number of previous pregnancies. The overall incidence of UTR was 12.6%. Analysing the data with respect to the number of previous pregnancies the incidence of UTR were 0%, 0%, 3.8%, 8.3%, 21.7% and 37.5% among patients with 0.1, 2, 3.4 and 5 previous pregnancies respectively. However, all cases of UTR in the affected patients were clinically mild, manifesting with urticarial rashes and pruritus without any features of anaphylaxis. This data would suggest that the risk of UTR increases with the number of previous pregnancies. Therefore, multiparous patients need closer observation during transfusion therapy.

Blood Transfusion and Agglutination

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Blood Transfusion

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...
Blood Typing01:10

Blood Typing

Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target antigens A,...
