Difference between infusion & transfusion.

Infusion and transfusion are two processes of transferring substances to the blood. The main difference between the two is that infusion is the transfer of a substance to the blood, altering the state of blood, whereas transfusion is the transfer of a substance to the blood without altering the state of blood.

Infusion is a therapy that can be received through a needle or catheter. It is important when there is no capable oral therapy. Infusion therapy is taken intravenously, epidurally, intramuscularly, or subcutaneously. The main importance of infusion therapy includes hydration or quick delivery of medications. Other substances used in infusion therapy include antibiotics, antiemetics, antifungals, antivirals, biologics, blood factors, chemotherapy, corticosteroids, growth hormones, immunoglobulin replacement, immunotherapy, and inotropic heart medications.

On the other hand, transfusion is the process of receiving blood and blood products intravenously. It can replace the lost components of the blood and can be used in various medical conditions. It is potentially a life-saving process that can replace blood during surgery or injury. The blood components that can be transfused include red cells, white cells, plasma, and platelets.
