when was the first synthetic blood approved for human use
Blood substitute The first approved oxygen-carrying blood substitute was a perfluorocarbon-based product called Fluosol-DA-20, manufactured by Green Cross of Japan. It was approved by the Food and Drug Administration (FDA) in 1989. Because of limited success, complexity of use and side effects, it was withdrawn in 1994. However, Fluosol-DA remains the only oxygen therapeutic ever fully approved by the FDA. As of 2017 no haemoglobin-based product had been approved.[9]
