A machine, commonly known as a cell saver, is used to recover red blood cells lost during surgery and return them to circulation in the patient’s body. The first machine of this type was developed during the Vietnam War and used extensively in the field. This method may be acceptable for some of Jehovah’s Witnesses.
The salvage of blood lost in surgery effectively minimizes the need for blood transfusion. This technique has had successful applications in various operative procedures, including cardiac surgery, spine surgery, liver transplantation, trauma procedures, and vascular surgery.
