The term ââ¬ËPhlebotomyââ¬â¢ Essay
venesection comes from the classical word phlebos, meaning veins, and tome, meaning incision. Bloodletting is one of the humanitys oldest medical examination practices, dating back thousands of years and is linked to many ancient cultures, including the Mayans, Aztecs, Egyptians and Mesopotamians. Evidence suggests rakebath for therapeutic reasons may fill begun in Egypt rough 1400B.C. Tomb paintings from this time show the application of a leech to a affected role. The enjoyment was to cure a person despicable from some anatomy of infirmity (leprosy, plague, pneumonia, stroke, and inflammation, pretty much anything). The patient was pierced or restrict and then drained of several ounces of blood until they fainted.In ancient Hellenic culture, a physician named Galen of Pergamon took the practice in a more scientific direction when he discovered that arteries were filled with blood, not air. Galens start out to battue was based on two key concepts. First, Galen believe d that blood didnt circulate, but stayed motionless in the personify until it either went stagnant or was let out. Secondly, he thought the balance of the four humors (blood, phlegm, black insolence and yellow bile) was the source of health or illness. Mapping out the blood vessels of the body, Galen would slashed his patients in different atomic number 18as, depending on what area he valued to accost. For example, the right hand would be cut and drained in score to treat liver problems. He was also know to give his patients drugs in magnitude to induce vomiting or urination. Bloodletting was also freehanded in the early years of some of the worlds intimately practiced religions.The Talmud (a central text of Judaism) included rules for days where bloodletting could be practiced. Early Christian writings outlined which saints days were the best for the ritual. Bloodletting is also referenced as a treatment for fevers in some early Islamic texts. Continuing into the middl e ages two surgeons and grooms were specializing in this bloody practice. Barber games which still decorate the outsides of barber shops are a leftover tradition dating back to the days of barber bloodletting. The swirling red line on the pole represents the blood itself, the white represents the tourniquet, and the pole itself represents the stick the patient would squeeze in his/her hand in order to dilate the veins.Bloodletting as a medical procedure migrated to the Americas along with the European colonists, stretching in time from the residents of Plymouth to the Founding Fathers. Physician benjamin Rush(one of the signers of the Declaration of Independence) recommended bloodletting to his patients on a consistent basis. As a matter of fact, George Washington, the head start U.S. president, died in 1799 from a throat contagious disease after having 3.75 liters (9 pints) of blood removed from his body within a 10 hour period as treatment for a throat infection. The wearyi ng of 16-30 ounces (1-4 pints) of blood was typical. Blood was often caught in a shallow bowl. When the patient became faint, the treatment was stopped. Bleeding was often encouraged over large areas of the body by multiple incisions. By the end of the nineteenth nose toleratedy (1875-1900), Phlebotomy was declared quackery.The main process of bloodletting in 19th century medicine included the use of leeches to drain blood from a patient. During the 1830s, France merchandise approximately 40 million leeches for the purpose of bloodletting. Francois-Joseph-Victor Broussais, a French physician, would reportedly recommend his patients be treated with as many as 50 leeches at a time. Bloodletting, also known as venesection, managed to survive into the first part of the twentieth century it was even recommended in a 1923 form of a textbook called The Principles and Practice of Medicine. During those days, there were four main bloodletting modes practiced by physicians. The first wa s the continued use of leeches as a bloodletting source.The second was called arteriotomy, a process in which the arteries in the temples would be punctured and bled. The third was phlebotomy (also known as breathing a vein) where a large external vein would be cut in order to draw blood. The last was scarification a particularly stomach-turning method which involved one of a varied set of tools made for the purpose of attacking superficial blood vessels. Such devices included spring-loaded lancets and a circular, mutli-bladed, device known as a scarificator. The scarificator had a series of cardinal blades. The device was cocked and the trigger released spring-driven rotary blades that caused many shallow cuts. The scarificator seemed more pitying than other bloodletting instruments.The reason bloodletting died comes as no confusion to modern readers that bloodletting killed far more people than it cured. Still, it wasnt until the 19th century that members of the medical commun ity seriously questionedthe merits of this practice. In the 1830s, Pierre Charles Alexandre Louis convincingly argued against the perceived effectiveness of phlebotomy for the treatment of pneumonia and fever. Ironically, with the gradual decline of bloodletting there was an increase of other dangerous and ineffective treatments, such as the use of electricity, elixirs and potions.These medications gained popularity for the same reason that bloodletting had in earlier time it sometimes worked as a placebo. Because the patients believed that receiving electric shock therapy would heal their illness, the mental factor may have been enough to actually make them olfactory property better. As the 20th century brought a myriad of new medical knowledge, technology and medicine, however, these archaic practices (including bloodletting) died out almost entirely within a few decades. With the advent of modern medicine, bloodletting was remembered as a diachronic fad, similar to the guillo tine as a form of death penalty.after nearly a century of new medical knowledge and leaps of board that include the development of electron microscopes, mapping the human genome and cloning invigoration tissue, how is it possible that the medical field is reconsidering the use of this ancient practice? The resolvent is fairly straightforward Where ancient bloodletting was used to treat and obstruct almost every infirmity imaginable, modern bloodletting (or phlebotomy) is used unaccompanied to treat specific medical conditions of which medical research has proven the benefits. research has shown that bloodletting could improve cholesterol, blood pressure and blood glucose levels for people suffering from metabolic syndrome. Metabolic syndrome is a term used to describe the come of medical problems facing people who are obese, such as hypertension, insulin opponent and glucose intolerance.People with this condition are at risk for clots and strokes. Bloodletting thins batch t he patients blood, helping to prevent these problems. Perhaps the most leafy vegetable use for modern bloodletting is a hereditary iron-overload condition known as hemochromatosis. As iron builds in the patients blood, it terminate have a negative impact on various areas of the body, including the rawness and the joints. This can eventually lead to disease and organ failure. Bloodletting, now normally referred to as a blood donation, is applied as the main treatment for hemochromatosis, with patients having their blood taken on atleast an yearly basis for life.There is another modern form of bloodletting outlay noting, if nothing else, because it never actually went away in the first place. Leeches have continued to be used for certain medical treatments throughout the 20th century right up to the present day. Whereas leeches were formerly used to treat all sorts of injuries and sicknesses, today they are mostly used by doctors in the reattaching of severed body parts such as fi ngers and toes. Attaching leeches is effective because they can help to get rid of any extra blood that cogency start problematically flooding in the tissue.Phlebotomy plays a major role in preventive healthcare, diagnosis and treatment of diseases. Although the instruments and methods used for obtaining blood in the beginning may appear crude in equation to the instruments and methods we use today, the concept remains the same. The exception being, instead of using bloodletting as a cure to remove the illness we use it as a way to analyze, diagnose and treat the illness. Without phlebotomy the process of accurately diagnosing diseases and infections would be impossible.
