FIELD: medicine.
SUBSTANCE: presented method involves washing of a pre-preserved biological prosthesis in a solution of a sterile 0.9% sodium chloride solution and placement in a sterilizing agent on phosphate buffer. At that, a mixture of bactericidal preparations consisting of ethylparaben, methylparaben, propylparaben and phenoxyethanol prepared on 0.05-2.0 M phosphate buffer and containing 5-20% of ethanol at pH 4.0-8.0 in the concentration of 0.2-2.0% and temperature of 5-40°C is used as a sterilizing agent.
EFFECT: increased strength of the biomaterial during storage and reduced time of bioprosthesis washing before implantation.
