  • Title: [Effect of sodium hydroxybutyrate on coronary hemodynamics and microcirculation during hypotension caused by blood loss].

    Abstract:
    Experiments of 34 dogs were made to study alterations in the cardio- and hemodynamics and microcirculation in the mesenterium during hypotension caused by hemorrhage after intravenous injection of sodium hydroxybutyrate and intravenous re-infusion of heparinized blood under a pressure of 80-120 mm Hg. It was established that single injection of sodium hydroxybutyrate in a dose of 180-200 mg/kg after a 60-minute decrease in the arterial pressure to 40 mm Hg increases pump function of the heart, venous blood returns to the heart, and improves microcirculation. This improvement manifests by the rise in the blood flow rate in the microvessels and in the number of functioning capillaries, and by diminution of red cell aggregation. Favourable effect of the drug is seen within the first minutes after injection and remains unchanged for one hour. Intravenous blood pumping under long-term hypotension is an effective approach to making for the lost blood in the presence of the preceding injection of sodium hydroxybutyrate.
