What is hemodilution?

Hemodilution is the process of diluting blood with fluids other than blood. This can be done for a number of reasons, including:

Decreasing blood viscosity to improve circulation

Increasing tissue oxygenation

Reducing the risk of blood clots

Replacing lost fluids and electrolytes

Hemodilution is often used in the following situations:

Major surgery: Hemodilution may be used before, during, or after major surgery to reduce the risk of blood loss and improve circulation.

Trauma: Hemodilution may be used to replace lost fluids and electrolytes in trauma patients.

Hemolytic anemia: Hemodilution may be used to treat hemolytic anemia, a condition in which red blood cells are destroyed.

Polycythemia vera: Hemodilution may be used to treat polycythemia vera, a condition in which the bone marrow produces too many red blood cells.

During hemodilution, a person's blood is mixed with a variety of fluids, including saline, Ringer's lactate, and dextran. The amount and type of fluid used will depend on the person's individual needs.

Hemodilution can be a safe and effective way to treat a variety of medical conditions. However, it is important to be aware of the potential risks associated with hemodilution, including:

Hypovolemic shock: This can occur if too much fluid is removed from the body.

Electrolyte imbalances: This can occur if the fluids used for hemodilution do not contain the same electrolytes as blood.

Infection: This can occur if the fluids used for hemodilution are not sterile.

Hemodilution should only be performed under the supervision of a qualified medical professional.
