Abstract

BACKGROUND:

The aim of this study was to investigate the effects of small volume resuscitation with 7.5% hypertonic sodium chloride (HSS), hydroxyethyl starch 130/0.4 solution (HES), and hypertonic sodium chloride hydroxyethyl starch 40 injection (HSH) on endotoxin shock rat lung.

METHODS:

Thirty Sprague-Dawley (SD) rats were divided randomly into 5 groups ,Group C (negative control group), Group E (lipopolysaccharide, LPS +4 ml/kg saline), Group HSS (LPS +4 ml/kg HSS), Group HES (LPS +4 ml/kg HES) and Group HSH (LPS +4 ml/kg HSH). Endotoxin shock model of rat was produced by injection with LPS. Then small volume resuscitation with different fluids was implemented in each group, respectively.

RESULTS:

Compared to Group C(negative control group), lung injury in the other four groups was increased. Compared to Group E(LPS +4 ml/kg normal saline), lung injury of Group HSS(LPS +4 ml/kg HSS), HES(LPS +4 ml/kg HES), and HSH (LPS +4 ml/kg HSH)was lessened. Compared to Group C, oxygenation index in Groups E, HSS, HES, and HSH were decreased (P < 0.01). Compared to Group E, oxygenation indexes in Groups HSS, HES, and HSH were significantly increased (P < 0.01). Data of tumor necrosis factor (TNF)-α of lung tissue had similar results. However, protein concentration of bronchoalveolar lavage fluid and hydrogen sulfide (H(2)S) concentration indicated contrary results.

CONCLUSION:

Small volume resuscitation with 7.5% hypertonic sodium chloride, hydroxyethyl starch 130/0.4 solution, and hypertonic sodium chloride hydroxyethyl starch 40 injection could lessen lung injury caused by lipopolysaccharide. And this effect had relation to change of TNF-α and H(2)S.
