OBJECTIVE To investigate the effects of Shenfu injection on hemodynamics in hemorrhagic shock dogs. METHODS The model of hemorrhagic shock was established by bleeding of femoral artery in dogs. Then recorded the output and started infusion. One times the amount of blood loss of drug solutions which was diluted with saline was infused for other groups with relative dose,respectively. The hemodynamic parameters were observed before bleeding,after 5 min,10 min,20 min,30 min,60 min,90 min,including HR,SBP,DBP,L...
