家兔血流动力学生理参数的测定

STUDY THE HEMODYNAMICS PARAMETERS OF RABBIT

目的 :测定家兔血流动力学生理参数 ,为教学和科研中心功能的分析提供参考依据。方法 :对麻醉后的家兔经颈总动脉行左心室插管术 ,通过压力换能器将左心室内压力信号输入计算机 ,利用计算机BL～ 4 10生物机能实验系统测定家兔血流动力学常用参数生理值。结果 :MP:14.1± 1.7k Pa,LVSP:18.7± 2 .1k Pa,L VEDP:- 0 .0 2± 1.5k Pa,LV+dp/ dtmax:517± 12 1k Pa/ s,LV- dp/ dtmax:378±117k Pa/ s。结论

Objective:To study the hemodynamics parameters of rabbit and provide the reference of hearts function for education and study.Methods:Insert pipes into the anesthetized rabbitsleft ventrides through their neck arteries,input the pressure signal into the computer using pressure energy converter,measure the frequently used physical parameter with BL 410 Creature Function Test System.Results:MP:14.1±1.7kPa,LVSP:18.7±2.1kPa,LVEDP: 0.02±1.5kPa,LV+dp/dtmax:517±121kPa/s,LV dp/dtmax:378±117kPa/s.Conchusion:Gain aroulable rabbitshemodynamics parameter.
