[The effects of 20% saline solution on the circulatory dynamics during the hemorrhagic shock state].

Abstract
This experiment was performed to study the effects of administration of 20% saline solution 1.5 ml.kg-1 on the circulatory dynamics during the hemorrhagic shock state. Administration of 20% saline solution 1.5 ml.kg-1 during the hemorrhagic shock produced twofold increase of the mean arterial blood pressure for one hour, 2.5 fold increase of the cardiac output, increasing tendency in the mean pulmonary arterial pressure, central venous pressure, and the heart rate, accompanied by decrease in total peripheral resistance and the pulmonary blood vessel resistance. There were no improvements in acidosis and hematocrit. These data suggest that the circulatory improvements after the administration of 20% saline solution depend on an increase in cardiac output as the result of improvements in both pre- and after-load, but not of plasma volume expansion. The results also suggest that the administration of 20% saline solution 1.5 ml.kg-1 is useful for an emergency case with acute circulatory insufficiency or for emergency resuscitation.
