| 摘 要： | 本文报告20只兔胫骨以不同速度延长时用末梢微循环测定系统动态连续监测局部血流量变化的结果,发现一次延长>1 mm时,局部肌肉血流量开始急骤下降,恢复延长前血流量所需的时间>8 h。作者认为肢体的血管、肌肉等组织对1 mm/次/d延长速度有相当大的生物适应性。延长速度>1 mm/次/d易造成局部血流量大幅度减少。延长肢肌肉萎缩、肌力减弱可能与血流量减少有关。 |

| Abstract: | The regional blood flow measurement (RBFM)of lenghtened limb with a peripheral circulation mesuremnt system was carried ou t in 20 rabbits after their tibia was lengthened in different lengthening rates.It was found that whenever a limb was lengthened with a rate over 1 mm/day,the RBFM of the lengthened limb decreased rapidly and returned to preoperative level 8 hours later.It is believed that the vascular and muscular tissues of a limb possess good adaptive capcity to the lengthening rate of 1 mm/day,When the lengthening rate exceeds 1 mm/day,it is liable to result in a significant re-duct of regional blood flow,and then atrophy and weakening of the muscles will occur. |
