摘　　要：本文对猫颅脑伤模型进行了伤后早期不同时间胃网膜动脉多普勒测定，并对比研究了伤后早期胃血流及其声像图特征。结果显示，实验动物颅脑撞击伤后，收缩期血流峰值速度（ＰＦＶ），舒张末期血流速度（ＥＤＶ）和平均血流速度（ＭＦＶ）３小时测值最大，到６小时又回落接近伤前水平。此外，动脉搏动指数（ＰＩ）和阻力指数（ＲＩ）则随着伤后时间的延长逐渐增大，将上述参数行组间和组内对照，差异显著（ｐ＜０．０５，ｐ＜０．０１）Changes in gastric blood flow and ultrasonogram are discussed,eparately in head-injuriedand non-injuried cats. boppler flow parameterters in gastro-epiploic arteries were measured at 1,3,6 hours after se-vere brain injury. The results showed that the peak syxtolic flow velocity(PFV),end diastolic flow velocity(EDV),and mean flow velocity(MFV)increased significantly in comparison with control group.The differenceis significant(p<0.01).The dynamics of blood flow in head-injuried cats was evaluated by pulsatility index(PI)and resixtance index (RI)
