Abstract:
Objective To evaluate the effect of Shenfu injection(参附注射液) on hemodynamics and oxygen delivery(DO2) metabolism in dogs with cardiogenic shock.Methods A dog model of acute myocardial infarction was made by ligating the midpoint of left coronary artery.When the cardiogenic shock was found by the Swan-Gans vessel,18 dogs with cardiogenic shock were divided randomly into three groups: Shenfu,dopamine and control groups.The following drugs were intravenously administered: Shenfu injection 1 ml/kg to the Shenfu group,dopamine 10 ?g?kg-1?min-1 to the dopamine group and NaCl 5 ml/kg to the control group.Before the model was made and after the drugs were given for 30,60,90,120 and 180 minutes,the changes of the parameters of hemodynamics were monitored through the Swan-Gans vessel,inculding cardiac output(CO),pulmonary arterial wedge pressure(PAWP), pulmonary artery pressure(PAP),central venous pressure(CVP),heart rate(HR),blood pressure(BP) and angiosthenia(AP).Then the results of stroke volume(SV),stroke work(SW),mean arterial blood pressure(MAP),systemic vascular resistance(SVR) and pulmonary circulation resistance(PVR) were calculated by formulae.Arterial blood and mixed venous blood were used for blood gas analysis to measure and calculate the following hemodynamic parameters: DO2,oxygen consumption(VO2) and oxygen uptake rate(ERO2).The results were compared.Results ① In the control group,after NaCl was given,CO,SV,SW,HR and MAP were decreased gradually at the time points,while the PVR,PAWP and CVP were progressively increased at the same time(all P
