Blood transfusion

The physicians evaluated the risk and benefits of using the blood transfusions and clearly understood the risks. If the outcome was death, without a transfusion the physicians by passed the normal protocol for evaluating the donor and the necessary lab tests that are required. The physicians generally practiced Western medicine and knew the risks associated with blood transfusions in Africa. As the practice of transfusions grew, so did the new development of other related risks associated…

are branches inside the Medical Technology that people can specialize on. Hematology is related to analysis of blood. Microbiology is to find the bacteria in wounds. Microbiologists in Medical Technology decides what antibiotics to use for what case. Blood banking is the transfusion of blood. For instance, Carter Blood Care. When people get into accidents, they have to figure out their blood type and match the right antibodies. There are various fields inside this career. He is a generalist so…

are inherited blood disorders which cause the body to make fewer healthy red blood cells and less haemoglobin (an iron-rich protein in red blood cells). The two major types of thalassaemia are alpha- and beta thalassaemia. Haemoglobin in red blood cells has two kinds of protein chains: alpha globin and beta globin. If the body doesn't make enough of these protein chains, red blood cells don't form properly and can't carry enough oxygen. 2. APLASTIC ANAEMIA: Aplastic anaemia is a blood disorder…

uncertainty. On the 15th of November 1910, Dr. James Herrick made the first discovery of sickle cell disease. He encountered multiple patients complaining of similar symptoms of acute chest pain. Dr. Herrick received a blood film, a test used to look for irregularities in red blood cells, each patient results showed signs of sickle cells. In later years’ studies showed that the disease was more common in people who are African-American, Hispanic, Central and South America descent. Currently,…

According to the article “Managing Sickle Cell Disease”, sickle cell disease is an inherited disorder affecting the red blood cells. The disease causes the red blood cells to become rigid and half-moon shaped, resulting in obstruction of capillary blood flow. Decreased oxygen to the tissues results in pain. The disease is inherited and has the greatest prevalence among Black Americans and Hispanics in the United States. Inheritance is autosomal recessive and results in production of sickle…

due to the change of single nucleotide in the beta globin chain. In this disease, normal red blood cells get changed into to sickle shaped or disc shaped showing concave from the center. They may change their shape in the form of banana. Cause of disease: Sickle cell anemia is caused due to deficiency of iron in the body which results in change in the shape of red blood cells. How it occurs: Red blood cells are flexible due to which they can easily pass from the delicate tubes called…

Hematocrit is a test that essentially test the total RBC’s volume in the blood. A small blood sample is extracted from the subject and the sample is then centrifuge to separate heavy components from lighter components. Typical that means that the heavy RBC’s should be compact at the bottom, while the lighter and less dense plasma so be at the top. Once separate the individual components can be accurately measured and assessed for determining the percentage of the RBC’s in the sample. If one…

relieved, for example when resuscitation and wound care are suboptimal, then persisting ischaemia will worsen, and the burn depth will increase. The third zone of hyperaemia is at the periphery of the burn characterised by a reversible increase in blood flow and inflammation. Fig.5. JACKSONS ZONESOF TISSUE INJURY. BURN CENTER REFERRAL CRITERIA [7] A burn center may treat adults, children, or both. Burn injuries that should be referred to a burn center include: 1. Partial thickness burns…

occur. Transfusion before transplantation was found to reduce solid organ transplant rejection by inducing regulatory T-cells and immunomodulation with down-regulation of the immune system. Similarly, ABO blood group matching, tissue typing, cross matching and using immune suppressants are among the methods used to avoid rejection. Interestingly, clinical observation in humans noted significant correlation between the rate of bone marrow rejection and the number of antecedent transfusion. This…

be carrying. People are usually educated on their genotypes after their child has developed a dreadful disease like sickle cell anemia. Sickle cell anemia is a chronic blood disorder in which a mutated form of hemoglobin causes the red blood cells to sickle. When the red blood cells sickle, they can cause clogging within small blood vessels. This can lead to severe pain, organ damage, and paralysis because the body does not get enough oxygen (Holtzchaw, Fred, Holtzclaw Theresa 108). Learning…
