Blood Disorder Flashcards
Main Blood Disorder Drug
Anti Anemia Anti-Coagulant Anti-Platelet Anti-Fibrinolytic Anti-Hyperdemic
Anemia
Low con of HB in blood, Low o2 in blood
-2SD (Male14-16 gram %, Female 13-15 gram %)
Anemia characterized by
Pallor- Pale skin & mucous membrane
Fatigue - Tiredness
Shortness of Breath -Dyspenea
Type of Anemia
Microcytic(Fe)
Macrocytic(B12,Folic acid) (Megaloplastic)
Normocytic
Mixed
Normocytic Anemia
BM failure
Endocrine failure
Chronic disease
Clinical Indication Fe deficiency
Dietery deficiency Chronic blood loss Increased demand Inadequate absorption Early tt of pernicous anemia
Pernicous anemia
Atrophy of gastric mucosa(Produce intrinsic factor- Absorb B12)
B12 deficiency Megaloplastic Anemia
Anemia TT concept
Correct cause
Iron replacement theraphy
Anemia Oral Preparation
Ferrous Fumarate(Syrup)
Ferrous Gluconate
Ferrous Sulphate
Ferrous Succinate(Elixir)
Oral Anemia start small dose & increase gradually
Avoid GIT upset
Better with food
Oral Anemia Failure
Bad compliance
Continuous blood loss
Wrong diagnosis
Oral Anemia Adr
GI upset, might blacken the faces
Parenteral anemia Indication

Deferoxamine(desferal)
Chronic Iron Toxicity(Haemochromatosis)
in Chronic Iron Theraphy Repeated blood transfusion Haemolytic Anemia tt Venesection in non-anemic Chelation in anemic
b12 importance in
