title: [Effectiveness of oxygen delivery to tissues during complete replacement of blood by bovine polyhemoglobin].
abstract: The study has been performed to test the hypothesis on feasibility of omitting pyridoxylation in production of bovine polyhemoglobin as compared to polyhemoglobin from human red cells. The model of a complete replacement of rabbit blood for polyglucin (Het approximately 2%) was used to compare efficacy characteristics for O2 delivery to tissues upon introduction of bovine polyhemoglobin against rabbit red cells. Immediately after the replacement, O2 release efficacy and that of circulation were identical, whereas 30 and 60 min after it, developing decompensation of hemodynamics indicated inability of bovine heterohemoglobin, unlike own red cells, to increase A-B difference by oxygen, probably due to metform rise.
