吡那地尔预处理对失血性休克大鼠血流动力学影响的实验观察(Experimental study of the effect of pretreatment with piracetam on hemodynamics in rats with hemorrhagic shock) Experimental study of the effect of pretreatment with piracetam on hemodynamics in rats with hemorrhagic shock 2010-01-15 Shao Chunhong, Hu Deyao, Xue Chunsheng Abstract: Objective To observe the effect of PC preconditioning (Preconditioning) on hemodynamics in rats with hemorrhagic shock. Methods the rat model of hemorrhagic shock before 24 hours in advance, rats were given intraperitoneal injection 2 times 25 g/kg pinacidil pretreatment, pretreatment observation on heart rate (HR), mean arterial pressure (MAP), left ventricular systolic pressure (LVSP), isovolumic systolic blood pressure (IP), maximal rate of left the rise and fall of the ventricular pressure (+ dp/dtmax), peak systolic velocity (VPM) and the measured myocardial systolic ring area (Lo). Results pretreatment significantly enhanced cardiac function, HR, MAP and LVSP were significantly higher in the observation phase than in the control group. The values of dp/dtmax, VPM and Lo reflecting the contractile and diastolic properties of the myocardium were higher than those in the C group. Conclusion pretreatment with piracetam can improve the hemodynamics of hemorrhagic shock and reduce the cardiac function damage caused by hemorrhagic shock in rats.

Methods Pinacidil preconditioning was processed 24h (a dose of 25 g/kg i.p.in twice before hemorrhagic shock model.The) making changes of
