Blood transfusion
Overview
A blood transfusion is a routine medical procedure in which donated blood is provided to you through a narrow tube placed within a vein in your arm.
This potentially life-saving procedure can help replace blood lost due to surgery or injury. A blood transfusion also can help if an illness prevents your body from making blood or some of your blood's components correctly.
Blood transfusions usually occur without complications. When complications do occur, they're typically mild.
