Methods Hypernatremic dehydration and hemorrhagic shock models were produced by Trachtma's and Krausz's methods in Sprague Dawley rats. Hemorrhagic changes of mean arterial blood pressure (MABP), left ventricular end diastolic pressure (LVEDP), ±dp/dtmax and heart rate (HR) were registered on polygraph. Plasma Na +, urea lactate and taurine content were assayed. Results After treatment with HS, the hemodynamic changes of hemorrhagic shock rats were significantly alleviated, and tissue fluid redistributed. When the hemorrhagic shock animals were treated with HS containing taurine (HST), in comparison with HS treatment, the hemodynamic improvement and hemodilution were more obvious. When the hemorrhagic animals complicated with hypernatremia were treated with HS, the symptoms of dehydration and shock further deteriorated, when the hemorrhage with hypernatremia animals were treated with an infusion of HST, the symptoms of dehydration and shock were significantly ameliorated. Conclusion The therapeutic effect of HS with taurine is obviously better than HS alone. So when hemorrhagic shock was complicated with hypernatremia, HS with taurine is recommended in stead of HS alone.展开更多
