During pregnancy: 10-12 gm/dl i.e. physiological anaemia due to the increase in plasma volume more than RBCs volume.<br />www.freelivedoctor.com<br />
  3. 3.

  9. 9. Iron Deficiency Anaemia<br />www.freelivedoctor.com<br />
  10. 10. Iron Deficiency Anaemia<br />Iron Deficiency Anaemia<br />It is the most common type of anaemias (95%).<br />Daily Requirements:Normal iron requirement is 10 mg/day of which 1mg is absorbed. Requirement increases during pregnancy to 15mg/ day.<br />www.freelivedoctor.com<br />
  11. 11. Iron Deficiency Anaemia>Aetiology<br />Inadequate intake of iron.<br />Defective absorption of iron e.g. achlorhydria.<br />Increased demand e.g. menstruation and pregnancy.<br />Chronic blood loss e.g. abnormal uterine bleeding and piles.<br />www.freelivedoctor.com<br />

  33. 33. Congenital Spherocytosis<br />An autosomal dominant disorder in which there is deficiency in the lipoprotein of cell membrane leading to increased rigidity of the RBCs and hence its destruction especially in the spleen.<br />www.freelivedoctor.com<br />

Thalassaemia<br />a- thalassaemia major (homozygotes):<br />The foetus with this disorder is affected in utero showing polyhydramnios, erythroblastosis, anaemia and hydrops resembling Rh-incompatibility.<br />This foetus does not survive due to inability of oxygen transfer as the a-chain is responsible for O2 carrying capacity.<br />www.freelivedoctor.com<br />
  39. 39. Thalassaemia<br /> a- thalassaemia minor (heterozygotes):<br />Patient develops mild progressive anaemia during pregnancy.<br />www.freelivedoctor.com<br />
  40. 40. Thalassaemia<br />ß-thalassaemia major (homozygotes):<br />The disorder starts in childhood leading to death of the patient mostly in the 2 nd or 3rd decade.<br />www.freelivedoctor.com<br />
  41. 41. Thalassaemia<br />ß-thalassaemia minor (heterozygotes):<br />As a- thalassaemia minor.<br />www.freelivedoctor.com<br />
  42. 42. Thalassaemia<br />Effect on pregnancy:<br />* ß-Thalassaemia major is rarely encountered in pregnant women, but if this happened the prognosis is poor.<br />* Anaemia becomes severe in mid-pregnancy and may result in heart failure.<br />www.freelivedoctor.com<br />
  43. 43. Sickle Cell Anaemia<br />An autosomal inherited disorder in which glutamic acid in position 6 of the b - chain of the haemoglobin molecule is replaced by valine. This leads to production of HbS. Hb S on exposure to hypoxia forms insoluble aggregations and RBCs become sickle-shaped and are subsequently fragmented.<br />In addition, these sickle-shaped cells increase the blood viscosity and occlude blood vessels of various organs.<br />The manifestations appear usually in homozygous not in heterozygous.<br />www.freelivedoctor.com<br />
  44. 44. Sickle Cell Anaemia<br />Clinical picture:<br />* Feature of anaemia and haemolytic jaundice.<br />* Multiple infarcts due to obstruction of microcirculation in the spleen, kidney, CNS, retina, bone, lungs and heart.<br />* Increased susceptibility to infections especially urinary.<br />* Attacks of severe abdominal pain and fever are common due to ischaemia and infarctions.<br />www.freelivedoctor.com<br />
  45. 45. Sickle Cell Anaemia<br />Clinical picture:<br />* Pre-eclampsia like- syndrome with hypertension, oedema and proteinuria may develop.<br />* Increased foetal wastage from abortion, preterm labour and growth retardation associated with placental insufficiency due to maternal placental bed thrombosis.<br />www.freelivedoctor.com<br />
  46. 46. Sickle Cell Anaemia<br />Management of sickle cell disease during labour: <br />* Avoid: hypoxia, dehydration and acidosis.<br />* Treat crises by: rehydration, bicarbonate, analgesic, heparin or low molecular weight dextran.<br />* Prophylactic antibiotic.<br />www.freelivedoctor.com<br />
  47. 47. Investigations of HaemolyticAnaemia<br />Serum bilirubin: raised.<br />Urine: increased urobilinogen.<br />Stool: increased stercobilinogen.<br />www.freelivedoctor.com<br />
  48. 48. Investigations of HaemolyticAnaemia<br />Blood film: <br />shows normocyticnormochromicanaemia and;<br />o Small spherical RBCs in case of spherocytosis.<br />o Target cells in case of Thalassaemia major.<br />o Sickling after inducing hypoxia by addition of Na bisulphite in case of sickle cell anaemia.<br />www.freelivedoctor.com<br />
  49. 49. Investigations of HaemolyticAnaemia<br />* Electrophoresis: detect type of haemoglobin in haemoglobinopathies.<br />* Estimation of glucose-6-phosphate dehydrogenase activity.<br />www.freelivedoctor.com<br />
  50. 50. Treatment of HaemolyticAnaemia<br />* Blood transfusion: in acute attacks.<br />* Folic acid and iron therapy: may be indicated.<br />www.freelivedoctor.com<br />
  51. 51. Treatment of HaemolyticAnaemia<br />* Splenectomy: may be beneficial in spherocytosis and some cases of thalassaemia major, but not to be done during pregnancy.<br />* Avoid precipitating factors: as hypoxia in spherocytosis and oxidative agents in G-6-PD deficiency.<br />www.freelivedoctor.com<br />
