The Mayo Clinic defines a blood transfusion as “a routine medical procedure in which donated blood is provided to you through a narrow tube placed within a vein in your arm”. The first human blood transfusion on record was conducted by Dr. Jean-Baptiste Denys, a French physician during the late 1600’s. Although Denys’ transfusions weren’t sound proof and often written off as unorthodox, he unknowingly ushered in a new era of medicine and laid the foundation for modern advances in Hematology. I choose this topic because I volunteer to donate blood four times a year alongside thousands of other people. On average these donations help save 4.5 million Americans that would die in a years’ time without a blood transfusion. These generous people …show more content…
Blood donations were being made on a regular basis come the 1900’s, yet the donator had to be present to give the blood directly to the recipient due to the accelerated coagulation of blood once it mixed with the open air. To rectify this problem hematologists started adding sodium citrate to the blood of the donator which would in turn delay the coagulation process by a few days. This allowed for the first storing of blood and introduced the term “Blood Bank”. Dr. Bernard Fantus, the director of the Cook County Hospital in northern Chicago, IL spearheaded this discovery. He thought by lowering the temperature of blood that it would lower its metabolism and thereby prolong its vitality. Unknowingly, Dr. Fantus created the first Blood Bank within the United States which would in turn change the course of medicine and human mortality forever. With this new leap forward in modern medicine, blood donations in the United Sates were at an all time high during the 20th Century due to WWI and WWII. Blood transfusions saved the life of countless individuals participating in the war efforts. The Red cross reported that they alone were “distributing 40 percent of the Countries blood supply”. Alongside aiding with the war efforts, blood transfusions also carried an array of health benefits as …show more content…
Blood transfusions allow for infected blood cells to be cycled out and replaced by fresh new blood cells in hope that hemoglobin levels will be restored within the body. When treating a person with liver disease it’s almost routine for them to experience several blood transfusions a month in order to help restore properly working blood cells back into their bodies. Blood transfusions are also a more structurally sound medical procedure when compared to several medications or radiation therapy alternatives, which can in turn cause a number of other problems. Another example of a disease that can be supported by the cycling of blood is Anemia. There several different types of anemia including aplastic, fanconi, hemolytic, and sickle cell anemia. The Mayo Clinic describes Anemia as “condition in which you don't have enough healthy red blood cells to carry adequate oxygen to the body's tissues”. Hematologists have been prescribing their anemia patients with several blood transfusions a month in hopes of training their bodies to make proper working blood cells once again. A study posted in the Journal of Palliative Medicine was conducted on 64 volunteer patients with several different forms of anemia to see if blood transfusions would benefit their hemoglobin values over a 15-day period. It turns out that 95 percent of the patients had some
In Blood In Blood Out is a drama directed by Taylor Hackford, and starring Damian Chapa (Miklo), Benjamin Bratt (Paco), and Jesse Borrego (Cruz), produced by Hollywood Pictures. The film was based off everyday life in East Los Angeles, from the 1970’s through the 1980’s. Damian Chapa stars as Miklo in the film, a Mexican-American who wanted to be accepted, not by his skin but for the Mexican within him. Benjamin Bratt (Paco) was the older cousin of Miklo, who learned his lesson throughout the movie and changed his ways. Jesse Borrego (Cruz) is the step-brother of Paco who was a talent artist, who ended up turning to drugs because of back problems caused by a rival gang incident.
In a world of constant evolution, a new generation of students deserves a contemporary education that will prepare them both academically and emotionally for the rest of their life. Vincent Lam’s novel, Bloodletting & Miraculous Cures, exhibits many traits that are beneficial to a 4U English class. Firstly, one of the main characters has a tragic flaw that negatively changes his way of life, similar to Hamlet and Amir studied earlier in the course. The author also explores the duality of human nature through different characters, tying the novel to one of the central themes in the course. This collection of short stories also illustrates many events and emotions that can be applicable to a 4U student and their journey into post-secondary life. In conclusion, Bloodletting & Miraculous Cures is an ideal new addition to the 4U English curriculum.
In the early 1900’s the United States’ medical field was stagnant causing many deaths in wartime. The majority of deaths in war times were often caused by diseases that were incurable. The United States medical field had to grow to current needs in war but it grew very slowly. The United States Army Ambulance Service was established on June 23, 1917 and the Sanitary Corps established one week later on the 30th. (David Steinert). The Sanitary Corps quickly expanded to nearly 3,000 officers during World War I but, this field was still much smaller than any other
On the 1950’s, the above statement drove the medical field insane, many doctors used to forced blood transfusion on Jehovah’s Witness and other doctors refused to provide treatment to those who refuse blood transfusion; even in a life threatening situation. For some time, doctors were put on a bad position, they faced a dilemma when caring for a Jehovah’s Witness patient because if a patient (Jehovah’s Witness) was not treated promptly must likely he/she would die, but if they were threated against his or her wishes with blood transfusions, the doctor was charged with “Assault”. As the time went-on, the blood transfusion topic became more controversial, mainly due to the increase number on cases of Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) acquired when used contaminated blood. The Scientifics, along with the medical field were forced to work together with Jehovah’s Witness in order to develo...

Charles Richard Drew was an African-American male born on June 3, 1904 in Washington D.C. He was very well-educated and intelligent, and he received his Doctor of Medical Science Degree in 1940 from Columbia University. During his residency at Columbia University’s Presbyterian Hospital, he became very interested in blood transfusions. Drew soon realized that the technology of blood transfusions was vastly limited; blood could only be stored for two days. He was determined to solve this dilemma because of the many lives it would save. Led by his motivation, Drew noticed that if the plasma was separated from the blood and the two were refrigerated separately, they could be combined up to a week later for a blood transfusion. He convinced Columbia University to start a blood bank and eventually established blood banks throughout Europe and the Pacific. Ironically, Drew died in 1950 after he had been severely injured in a car incident and wasn’t able to receive medical attention because of his race. According to an article entitled “Charles Drew,” “By the time he arrived at the more distant hospital for blacks he had lost so much blood that a transfusion was of no avail.” It was disputed whether or not Drew would have survived if given a blood transfusion immediately, and the story of his death angered many.
A blood transfusion is a procedure in which your child receives donated blood, including plasma, platelets, and red blood cells, through
Bad Blood: A Cautionary Tale focuses on the lives of many hemophilic patients and their journey to seek medical treatment which eventually led to exposure to hepatitis and AIDS for as many at 95% of the hemophilic community. The documentary focuses on the creation and consequences of a medication known as “factor 8”, which was used to stop bleeding in patients with hemophilia. The documentary exposes pharmaceutical companies and the fact that they were using contaminated blood to create such medications. These pharmaceutical companies were using unconventional methods of obtaining blood with the addition of not testing the blood for any diseases as they were looking to fulfill the large demand of the drug in the United States and many countries around the world. The film focuses on exposing the problem of the lack of governmental regulations to protect patients against the pharmaceutical companies in the United States, especially the hemophilic community. Patients with hemophilia had access to medication that would control their disease, however, that treatment was contaminated and would eventually cost them their lives. The film has one goal and that is to expose one of the worse outbreaks of diseases in the United States. It achieves its goal by putting emphasis on the fact that many lives could have been saved if someone had listened and stopped the pharmaceutical companies who were looking to make a profit out of their newly created “miracle”
(Topic sentence) According to the Health Care, Medicine, and Science, by Deborah Porterfield (1st citation), the word phlebotomy means “obtaining blood from a vein.” (P.34) Phlebotomy came a long way, as it was one of the traditional ways of medicine. According to Jamie Cohen (2nd citation), this practice is thought to have originated from ancient Egypt. From Egypt, this practice was starting to get used in Europe. Erasistratus, a popular physician in ancient Greece, believed that illness was caused due to too much blood. A little later, the Roman Empire believed in Erasistratus’s theory and performed phlebotomy more (P.1). With these two empires rising to the top, phlebotomy was spread throughout the world, including to places like India and Arabia as well. Years later in Europe, churches were not a big fan of cutting people open and let them bleed. So, who performed this...
Dr.Michelle Barron cautions that more research is needed to determine if treatments such as Blood plasma transfusion really does work since the data is mixed. In some instances the treatment appears to be helpful for certain types of diseases and other diseases that it has been used in, some people appear to get better and some don’t and the role the treatment plays in a patient recovery becomes
Red blood cells are carriers of oxygen. A percentage of these cells contain hemoglobin, which has the capacity to combine with iron. It's the iron-hemoglobin molecular structure that helps carry oxygen-rich blood from the lungs to your tissues and in return, delivers carbon dioxide back to the lungs to be expelled. A CBC with Differential that shows low red blood cell levels can indicate anemia. RBCs comprise about 40% of total blood volume; the RBC count is the number of red blood cells per cubic millimeter of blood (Rauen, 2012). Normal red blood cells values vary a...
By donating blood to insure there is enough in supply, the life we save may be our own.
Whether it be helping others that need a blood transfusion, or a supplemental source of income, donating plasma is an extravagant process that takes more effort than the normal citizen realizes. Previously I have explained the entirety of the donation procedure, including the waiting room ordeal, the donating, and then the end stages of the process. This information was presented so that others curious about plasma donation can vicariously live the donation process, and get a feel for what really goes on in the Biolife Plasma Center.
I will be investigating Human Blood as my specific tissue and giving an overview on the location, characteristics, and the benefits it has to the human body. Blood is extracellular matrix that is consists of plasma, red blood cells, platelets, and white blood cells. Blood is located within the capillaries/veins/arteries of the human body, which are blood vessels that run through the entire body. These blood vessels allow the blood to flow smoothly and quickly from the heart to distinct parts of the human body. The unique parts of human blood all work together for a purpose: the Red Blood Cells(erythrocytes) transports oxygen throughout the body, White Blood Cells(leukocytes) play a part in the bodies immune system, Platelets(thrombocytes) assist in creating scabs,
