Summary

In September 1993, the authors adopted the low glycerol rapid freezing technique for the cryopreservation of red blood cells. Over 2 years, they had 111 patients who used 227 bags of frozen-thawed blood. The period of time over which the blood was frozen in liquid nitrogen was from 21-40 days in 60% of the cases and more than 100 days in 7 cases. When compared to the previously utilized liquid-preservation (4 deg C) technique (up to 21 days), the new technique or cryopreservation permitted a relatively long-term preservation period. A combination of low glycerol rapid-freezing cryopreservation and liquid preservation techniques should be used to ensure an optimum supply of blood in hospitals.
