Essay about Sickle Cell Anemi An Autosomal Disorder
Sickle cell anemia is an inherited disorder that allows for some treatment, however the average life expectancy of a patient will Sickle cell anemia is only 30 years. An inherited gene causes the hemoglobin in the blood to become misshaped. Hemoglobin is the part of the red blood cells (RBC) that carries the oxygen to all of the body’s tissues and organs. This leads to inadequate amounts of oxygen to be carried on the hemoglobin, thus resulting in insufficient oxygenation for the patient. In order to fully understand Sickle cell anemia this paper will look at the following: description, risk factors, inheritance pattern, statistics, body systems most affected, prenatal screenings available, and nursing implications for practice.
Sickle cell anemia is an inherited autosome recessive disorder that results in an abnormal form of hemoglobin in the blood for which there is no cure (Lewis, Dirksen, Heitkemper & Bucher, 2014, p. 644). Pathophysiology of Sickle cell anemia includes the red RBC actually sickling and is referred to as a “sickling episode” (Lewis et al., 2014, p. 644). This can occur with no cause or by low oxygen tension in the blood (Lewis et al., 2014, p. 644). The actual shape of the RBC becomes very firm and takes on an almost crescent like shape (Lewis et al., 2014, p. 644). The misshaped RBC leads to an inability to pass through the capillaries as well as a normal, healthy RBC (Lewis et al., 2014, p. 644). Usually sickling is…
