The techniques for phlebotomy are applied in the treatment of a few medical conditions too. This is when we call it therapeutic phlebotomy. These are explained for better understanding.
Hemochromatosis: Why and how of application of phlebotomy in this condition?
In conditions when the body has an iron overload, more than the regular quantity of blood is drawn. As compared to 2.5 to a maximum of 10 ml in regular testing, around 470 ml of blood is drawn in this condition. It is drawn from the veins once every one to two weeks.
- The drawn blood may or may not be replaced by blood products or intravenous fluids.
- This eliminates around 250 mg of iron from the body in one draw.
- This improves the functioning of the heart and liver, provides relief from joint pains and leads to a reduced risk of liver cirrhosis.
- Phlebotomy procedure, in this case, is therapeutic phlebotomy.
- Repeated successful draws decrease the frequency of therapeutic phlebotomy.
Erythrocytosis: Why do we need to carry out phlebotomy?
- The body produces an increased number of RBCs to compensate for decreased oxygen supply to parts of the body. This can happen in sickle cell anaemia or polycythemia vera among others.
- The blood becomes thicker as a result of this.
- This induces headache, muscle fatigue, high blood pressure, shortness of breath, blurred vision, nosebleeds or even blood clotting.
- Phlebotomy is carried out to remove excess erythrocytes and improve blood flow.
