[One of the possible means of restoring the circulating blood volume in shock]

The possibility of increasing the efficacy of restoration of the circulating blood volume (CBV) in shock was demonstrated in experiments on 33 anesthesized female cats. Intramuscular injection of lactin one hour before blood loss (2% of body mass) in a dose of 5 U/kg or its intravenous infusion 90 minutes after blood loss in a dose of 50 U/kg was attended by restoration of the plasma volume in 5 hours. The prospects of further research into improvement of the efficacy of CBV in shock through activation of the body's reserves are substantiated.
