彩色多普勒超声诊断仪在高压电击伤血管损伤诊断中的应用

目的：了解彩色多普勒超声诊断仪在肢体电击伤血管损伤中的诊断价值。方法：采用ALTULTRAMARK9型彩色多普勒超声诊断仪于电击伤肢体切开减张前后作彩色多普勒检查，观察血管直径、血管壁、血管内膜、血管内容物和血流速度等变化。结果：严重肢体电击伤的血管尤其静脉血管血管壁肿胀、内膜粗糙、血管呈“串珠样改变”或血管内有泥沙样物质阻塞，血流速度减慢或血流通过。结论：彩色多普勒超声检查肢体电击伤后血管损伤，可以及时、准确的为临床诊断、治疗、和预后估计提供依据。

The Application of Color Doppler Ultrasonic Diagnostic Apparatus in the Diagnosis of Blood Vessel Injury due to High Voltage Electric Burn

Objective:To evaluate the application of color Doppler ultrasonic diagnostic apparatus in the diagnosis of electric injury.Method:Altultramark type 9 color Doppler ultrasonic diagnostic apparatus was used to observe the changes in blood vessel diameter,blood vessel wall,inner membrane,blood content and blood flow rate in electrically injured limbs post and prior to fasciotomy. Result:Blood vessels,especially veins wall were swelling,inner membrane became coarse,vessels had “ beaded changes” or vessels were obstructed by sand－ like materials.Blood flow lowered down. Conclusion:Using color Doppler ultrasonic diagnostic apparatus for investigating blood vessel injury post electric burn can provide timely and accurate evidence for clinical diagnosis and treatment and the estimation of prognosis.
