Anemia Anemia Presentation Transcript

  • Anemiawww.drjayeshpatidar.blogspot.com
  • DefinitionAnemia is a reduction in RBCswhich in turn decreases the oxygencarrying capacity of blood.Anemia is not a specificdisease state but a sign of anunderlying disorder.www.drjayeshpatidar.blogspot.in
  • Blood Components Red blood cells or erythrocytes appear asbiconcave discs averaging about 8 micro meter indiam. This flexible shape allows RBCs to squeezethrough narrow capillaries which is 3 micrometerwide. RED cells normally make up 40-50% of thetotal blood volume. Hemoglobin inside RBCscombine with oxygen to form oxyhemoglobin. Thered cells are produced continuously in our bonemarrow from stem cells at a rate of about 2-3million cells per second. People who are anemicgenerally have a deficiency in red cells.www.drjayeshpatidar.blogspot.in
  • Leukocytes White cells, or leukocytes make up a very small part ofbloods volume normally only about 1% in healthypeople. They occur most notably in the spleen, liver, andlymph glands. Most are produced in our bone marrowfrom the same kind of stem cells that produce red bloodcells. Others are produced in the thymus gland, which is atthe base of the neck. Some white cells are the firstresponders for our immune system. They seek out,identify, and bind to protein on bacteria, viruses, and fungiso that they can be removed. Other white cells (calledgranulocytes and macrophages) then arrive to surroundand destroy the alien cells. Individual white cells usuallyonly last 18-36 hours before they are removed, thoughsome types live as much as a year.www.drjayeshpatidar.blogspot.in
  • Platelets or thrombocytes, are cell fragments without nucleithat work with blood clotting chemicals at the site ofwounds. They do this by adhering to the walls of bloodvessels, thereby plugging the rupture in the vascularwall. They also can release coagulating chemicals whichcause clots to form in the blood that can plug up bloodvessels. Recent research has shown that platelets help fightinfections by releasing proteins that kill invading bacteriaand some other microorganisms. In addition, plateletsstimulate the immune system. Individual platelets are about1/3 the size of red cells. They have a lifespan of 9-10days. Like the red and white blood cells, platelets areproduced in bone marrow from stem cellswww.drjayeshpatidar.blogspot.in
  • Classification of anemia1. Hypoproliferative (resulting fromdefective production of Rbc) Iron deficiency Vitamin B12 deficiency Folate deficiency Decreased erythropoietin productionwww.drjayeshpatidar.blogspot.in
  • 2. Bleeding disorders(resulting from RBC loss) GI tract bleeding Menorrhagia Epistaxis Traumawww.drjayeshpatidar.blogspot.in
  • 3.Hemolytic (resulting from RBCdestruction) RBC membrane abnormality Sickle cell anemia Trauma Altered erythropoiesis Hemolysis Drug induced anaemia Infectionwww.drjayeshpatidar.blogspot.in
  • Iron deficiency anaemia Iron deficiency anaemia is caused by aninadequate supply of iron needed tosynthesis hemoglobin. Associated with inadequate absorptionor excessive loss of iron. Bone marrow produces Rbc`s that aredeficient in hemoglobin concentration.www.drjayeshpatidar.blogspot.in
  • Causes of iron deficiencyanaemia Acute & Chronic Bleeding Inadequate Intake of iron rich foods. Malabsorption syndrome Alcohol abuse (GI bleeding) Gastrectomy Pregnant women Menstruating womenwww.drjayeshpatidar.blogspot.in
  • Clinical Manifestations Clients often appear pale, particularly of palmlines,nailbeds,conjunctiva. Dry mucous membrane. Tissue hypoxia Fatigue Shortness of breath Dyspnea on exertion Palpitations Stomatitiswww.drjayeshpatidar.blogspot.in
  • Diagnostic tests: Hematology# Hb level: as low as 3.6gm/dl# Total erythrocyte count : below 3 million cells/dl# MCHC:20-30gm/dl# Serum iron level: as low as 10mg/dl#Iron binding capacity:350-500mg/dl Peripheral blood smear# Microcytic &hypochromic RBC`Swww.drjayeshpatidar.blogspot.in
  • Medical management Monitoring vital signs Semifowlers position Oxygen therapy Diet: high in iron,protein,vitamin [spinach, redmeat,eggyolk,wheat products] Oral iron preparations-ferrous sulfate0.2g tid,ferrous gluconate 0.3g bid. IV/IM administration iron dextran 100-250mg/dlwww.drjayeshpatidar.blogspot.in
  • Aplastic Anaemia Failure of bone marrow toproduce adequate amount oferythrocytes, leukocytes,platelets.www.drjayeshpatidar.blogspot.in
  • Causes of aplastic anaemia Idiopathic Exposure to chemicals causes bone marrowfailure Chemotherapy Radiation Drug induced:chloramphenicolwww.drjayeshpatidar.blogspot.in
  • Clinical Manifestations Fatigue Dyspnea Multiple infections Anorexia Pallor Palpitations Melena EpistaxisShort-limbed dwarfismwith bowing, combinedimmune deficiency,and late onset aplasticanemia.www.drjayeshpatidar.blogspot.in
  • Diagnostic test*Hematology: Peripheral blood Smear:pancytopenia. Erythrocyte count less than 1 million/mm2 Leukocyte count less than 2000/mm3 Total iron binding capacity :slightly reduced Platelet count 30,000-15,000/mm3*Fecal occult blood: positive*Urine chemistry: hematuria*Bone marrow biopsywww.drjayeshpatidar.blogspot.in
  • Medical management Monitoring vital signs Semi fowlers position Oxygen therapy Transfusion therapy: platelets & RBCs Antibiotics: penicillin. Analgesics Diet high protein, high calorie . Ferrous sulfate& iron dextran.www.drjayeshpatidar.blogspot.in
  • Pernicious Anemia Pernicious Anemia is a progressive anemiacaused by lack of intrinsic factor essentialfor the absorption of vitamin B12cobalamin. Lack of glycoprotein produced by parietalcells of gastric lining.www.drjayeshpatidar.blogspot.in
  • www.drjayeshpatidar.blogspot.in
  • Causes Deficiency of intrinsic factor Prolonged iron deficiency Malabsorption Poor administration of Vitamin B12 aftergastrectomy Bacterial /parasitic infections.www.drjayeshpatidar.blogspot.in
  • Clinical Manifestations Weakness Pallor Sore mouth Glossitis Dyspepsia (indigestion) Anorexia Wt losswww.drjayeshpatidar.blogspot.in
  • Sign&symptomswww.drjayeshpatidar.blogspot.in
  • Diagnostic test*Hematology Pbs Hb decreased. Erythrocyte count: blw 3 million/dl* Bone marrow Biopsy• Gastric analysis• Schilling testwww.drjayeshpatidar.blogspot.in
  • Medical management Vitamin derivatives Cyanocobalamin 100mg IM 2-3 times / week Folic acid upto 1mg/day orally Ferrous agents Digestantswww.drjayeshpatidar.blogspot.in
  • Sickle cell Anemia Sickle cell Anemia is a severe hemolytic anemiathat results from inheritance of sickle Hb (HBS)gene. This gene causes Hb molecule to be defective. The sickle Hb acquires a crystal like formationwhen exposed to low oxygen tension. RBC containing HBS loses its round, pliable,biconcave, disk shape & becomes deformed rigid&sickle shaped.www.drjayeshpatidar.blogspot.in
