Transcript

  • 1. Presented at: College Of Nursing Shifa Tameer-e-Millat University By: Muhammad Farooq RN, BSN, Dip Card.
  • 2.  At the end of this presentation, the audience will know:  What is Anemia  Causes of Anemia  What are different Types/classification of Anemia  Clinical feature of anemia  Diagnosis/investigation Of Anemia  Treatment Of Anemia
  • 3.  Taken from Greek language (an meaning absence & hemia meaning blood), the term Anemia is use to describe a reduction in the hemoglobin concentration or in the number of circulating RBCs below the level considered normal for the person's age, sex and locality.
  • 4. Normal reference values of Hb% Population Normal Hb% (at sea level) Newborn 14-22 g/dl Children 11-13 g/dl Non-pregnant women 12-16 g/d Pregnant women 11-15 g/d Men 14-18 g/dl Geriatric Age (Both Genders) 12 – 16 g/dl
  • 5. Normal Values of RBC Count Population RBCs Count (at sea level) Newborns–6 months 4.0–5.5 mil/µl Children 4.0–4.9 mil/µl Female 3.8 – 5.4 mil/µl Male 4.4 – 5.4 mil/µl
  • 6. Causes Of Anemia
  • 7.  There are many diseases, conditions and other factors causes anemia, few of which are:  Nutritional deficiencies i.e. Iron, vit B12, folate etc.  Hemolytic disorders e.g. Hypersplenism  Acute or chronic Blood loss e.g. from G.I Tract, Hemorrhage  Bone marrow disorder  Chronic Diseases e.g. Renal failure, Liver disease and Malignancies
  • 8. Causes Of Anemia (Cont….)  Infections and inflammation e.g. Malaria, Cl. Tetani  Toxicity (from drugs, metals and poisons) e.g. Lead Poisoning  Autoimmune disorders .e.g. SLE,  Heredity defect e.g. Thalassemia
  • 9. Classification Of Anemia  Classification of anemia can be made the bases of  RBCs Morphology  Etiology
  • 10. Morphological Classification  In morphological approach anemia is classified by the size or volume of RBC which is expressed as Mean Corpuscular or Mean Cell Volume(MCV).  On the basis of MCV, following are the types of anemia:  Microcytic Anemia (MCV<76fl)  Macrocytic Anemia (MCV >98fl)  Normocytic Anemia (MCV b/w 76 – 98 fl)
  • 11. Microcytic Anemia (<76 fL) Macrocytic Anemia (>98fL) Normocytic Anemia (76-98 fL) 1) Iron Deficiency anemia Vit. B12 & folate deficiency Vit B2 & B6 2) Thalassemia Alcoholism Hemolytic Anemia 3) Sideroblastic Anemia Acute Blood Loss Post Hemorrhagic Anemia 4) Lead Poisoning Anemia Liver disease Sickle Cell Anemia 5) Chronic Disease Anemia Aplastic Anemia Anemia in Pregnancy
  • 12. Etiological Classification  Etiological Classification of Anemia include  Anemia due to impaired RBC production  Anemia due to excessive destruction  Anemia due to Blood loss
  • 13. Clinical Features Of Anemia
  • 14. Clinical Manifestations  The clinical features of Anemia can result from following factors. 1. Tissue Hypoxia 2. Compensatory Mechanism 3. Rate of blood loss/destruction of RBCs 4. Causes of Anemia
  • 15. Symptoms of Tissue Hypoxia Largely affect Central Nervous System, Cardio-vascular system and Muscular system as their Oxygen requirement is high than other.
  • 16. Neurological Symptoms:  Dizziness, fainting, lack of concentration  Blurred or diminished vision  Headache, tinnitus, Vertigo  Paraesthesia in the fingers and toes  Insomnia, irritability, confusion
  • 17. Cardio Vascular Symptoms  Dyspnea  Palpitation  Angina On exertion or at rest (in sever cases)  Intermittent claudication  Heart Failure (high output)  Orthostatic Hypotension CV Signs includes  Tachycardia, bounding pulse  Loud HS with S3 over mitral or tricuspid area  Systolic murmur  Raised JVP
  • 18. Musculoskeletal symptoms  Exercise intolerance  Easy fatigability  Tiredness  Generalized Muscular weakness
  • 19. Other Features  Pallor of the skin, sclera and mucous membranes  Jaundice  Lymphadenopathy  Hepatosplenomegally  Bony Pain  Petechiae  Hair Loss  Anorexia, Weight Loss
  • 20. Compensatory Mechanism 1. Increase Cardiac Output (to maximize O2 delivery to tissue)  Tachycardia, bounding pulse 2. Increase Erythropoiesis  Liver and Yellow Bone marrow 3. Increase Plasma Volume 4. Redistribution of blood to more vital organs  By selective vasoconstriction to non-vital organs
  • 21. Specific Symptom due to Underlying Cause
  • 22. Iron Deficiency Anemia  People with an iron deficiency may experience these symptoms: 1. Pica habit 2. Koilonychias (spoon shape nails) 3. Red beefy tongue due to loss of papillae 4. Angular stomatitis/ cheilitis 5. Esophageal Web 6. Dysphagia, Odynophagia 7. RLS (Restless Leg Syndrome) in fewer cases PlummerVinson Syndrome
  • 23. Pernicious/ vit. B12 Deficiency Anemia  Paraesthesia and Numbness in hand and feet  Dementia, disorientation  Difficulty in walking  Sore tongue  Easy bruising or bleeding, including bleeding gums  Mood changes or Depression
  • 24. Sickle Cell Anemia 1. Leg Sore 2. Swelling of hand and feet 3. Sever Joint pain 4. Splenomegaly & LUQ Abdominal Pain 5. Susceptibility to infection 6. Delayed Growth in children 7. Retinopathy (visual disturbance)
  • 25. Thalassemia (Major)  Bony pain  Bossing of head  Delayed Growth  Splenomegaly  Hepatomegaly
  • 26. Aplastic Anemia  Frequent or prolonged infections  Unexplained or easy bruising  Nose & Gums bleeding  Prolonged bleeding from cuts  Skin rash
  • 27. How To Diagnose Anemia
  • 28. How To Diagnose Anemia History Physical examination Lab investigations
  • 29. History Taking  Diet (pure vegetarian)  Fever  Family history  Related symptom  Sign of other cytopenia
  • 30. History Taking (Cont….)  Last CBC  Previous diagnosis as anemia or transfusion  Medical history e.g. Chronic illness, drug use or abuse  Surgical Hx: Partial or complete gastrectomy  Previous jaundice, dark urine  Blood loss  Menstruation, Blood donation, GI loss, Concealed bleeding
  • 31. Physical Examination  Skin, sclera & Mucous membrane (for pallor)  Lymph node enlargement  Hepatosplenomegaly  Watch for the specific feature for suspected disease  Gum, Lips (Bleeding, cheliosis)  Nail fold (Koilonychea)  Facial or skull Bones abnormality
  • 32. Lab Investigations
  • 33. Lab Investigations 1) Complete Blood Count:  Hemoglobin level  Hematocrit Rate (M:40 – 52%, F: 35 – 46%)  RBC Count (M: 4.5 – 6.5, F: 4.0 – 5.4 mil/mm3)  MCV (76 – 98 fL) = (Hct/RBCs*10)  MCH (27 – 32 pg) & MCHC (32 – 36%)  WBCs and platelets
  • 34. Lab Investigations  S. Ferritin (M: 18-270 μg/L F: 18-160 μg/L)  TIBC (250–370 μg/dl)  Serum iron (M: 65–177 μg/dl, F: 50–170 μg/dl)  Reticulocyte Count (<2%)  Peripheral Blood Smear  Hemoglobin Electrophoresis
  • 35. Other Lab Investigations  Bone marrow aspiration  Liver and Renal Function Test  Coombs Test  Vit & mineral deficiencies  Hormonal Deficiencies
  • 36. How To Treat Anemia
  • 37. Treatment  Depends on Type, cause and severity  Goal is to increase Oxygenation to tissue and to treat the underlying cause  Certain modes of treatment include:  Dietary Changes or Supplemental Diet  Medicine  Procedures  Surgical Measurement
  • 38. Treatment  Dietary Changes & Supplements  To correct the deficient vitamin or mineral, the low level causes anemia.  Diet Rich in Minerals & Vitamins (B12, Vit C, folate)  Oral or Injectable supplement of these substance  Medicine including  Antibiotics / Anti-parasitic for infection or infestation  Hormones (Erythropoietin, Progesterone and Androgen)
  • 39. Procedures  Blood Transfusion  Usually used to treat severely anemic patients as in thalassemia major or sickle cell disease or to replace the blood loss after injuries or surgeries.  For multiple transfusion, Iron Chelation agent (Deferasirox) should be given to prevent iron over dose.  Allogeneic Bone Marrow Transplant  Surgical Measurement include repair or removal of G.I part causing blood loss and splenectomy.
