A discussion on the safety of blood transfusions

The most common adverse reactions from blood transfusions are allergic and febrile fever—associated reactions, which make up over half of all adverse reactions reported. Rare but serious adverse reactions include infection caused by bacterial contamination of blood products and immune reactions due to problems in blood type matching between donor and recipient. These adverse reactions are not common following blood transfusions but are tracked so that CDC can better understand them and develop interventions to prevent them.

Our quality management system includes a comprehensive herd management program to ensure the safety of all raw material used in production. All sourced cattle are born in the USA or Canada and obtained from pre-qualified suppliers that maintain comprehensive health and feed histories for each animal.

All collected material is held in quarantine until a post mortem inspection of the cattle is conducted by the onsite USDA veterinarian, and released for human consumption. Manufacturing process Our products are manufactured by an extensive purification procedure.

The purification of hemoglobin involves an automated state-of- the-art process consisting of multiple separation and filtration steps including specific hemoglobin isolation by large-scale, high-pressure ion exchange liquid chromatography.

During the manufacturing process hemoglobin is crosslinked and polymerized by reaction with glutaraldehyde under totally automated procedures. We have recently consolidated all manufacturing activities at our site in Souderton PA, where the facility is undergoing a multimillion dollar expansion to accommodate increased capacity for all production steps from collection of starting materials through aseptic fill finish.

Oxygen is indispensable to the life of all human tissues. Medical conditions such as ischemia or anemia can compromise tissue oxygenation.

Ischemia is a decrease or lack of RBC flow to an organ or body part due to obstructed or constricted blood vessels, as in heart attack, stroke and certain medical procedures.

Anemia is a deficiency of RBCs or hemoglobin associated with blood loss e.

Oxygen deprivation, even for several minutes, can result in cell damage, organ dysfunction and, if prolonged, death. The most critical property of each product is an ability to efficiently transport oxygen. There are two mechanisms by which oxygen transport is enhanced. Promoting both convective and diffusive oxygen delivery; the net result is an increase in oxygen delivery due to both an increase in the oxygen-carrying capacity of the plasma, and changes in the rheology of blood.

HBOC has a viscosity of 1. Addition of HBOC to blood decreases the overall viscosity. The products increase plasma and total hemoglobin concentration and thus increases arterial oxygen content.

Supplied in sterile IV infusion bags, the product is ready to be administered. No reconstitution or other preparation is required. Hemopure also does not need refrigeration and remains stable at room temperature for at least three years.
