What Researchers Did
Researchers reviewed the current status and promising developments in erythrocyte substitutes as alternatives to whole blood transfusions.
What They Found
They found that haemoglobin solutions and fluorocarbon emulsions are promising, non-blood-type-specific erythrocyte substitutes that could potentially satisfy some blood requirements. However, both require modification, such as reducing oxygen affinity and improving intravascular persistence for haemoglobin solutions, and requiring hyperbaric oxygen for fluorocarbons to significantly contribute to oxygen supply.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The primary limitation is that the discussed erythrocyte substitutes require significant modification before they can become clinically useful.
