Abstract
AIM: To evaluate the effect of small-volume hypertonic sodium chloride hydroxyethyl starch injection on histopathological changes in the intestinal mucosa and plasma levels of NO in rats with hemorrhagic shock.
METHODS: Male SD rats were hemorrhaged to the mean arterial pressure of 40 mmHg ± 5 mmHg for 30 min to induce hemorrhagic shock. Animals were randomly divided into three groups: rats resuscitated with 4 mL/kg of 5.0% hypertonic sodium chloride hydroxyethyl starch injection and retransfused shed blood, those resuscitated with lactated Ringer's solution (two times the volume of shed blood) and retransfused shed blood, and those undergoing sham hemorrhage. The dynamic changes in plasma NO concentrations were monitored, and pathological changes in the small intestine were observed.
RESULTS: After resuscitation with hypertonic sodium chloride hydroxyethyl starch injection, NO showed no significant changes (P > 0.05), and pathological changes in the small intestine were significantly reduced. In contrast, plasma NO concentration significantly decreased (P < 0.05) and pathological damage to the small intestine showed no significant improvement in rats resuscitated with lactated Ringer's solution.
CONCLUSION: Resuscitation with hypertonic sodium chloride hydroxyethyl starch injection reduces intestinal damage in rats hemorrhagic shock possibly via a mechanism associated with protection of endothelial cell function.
