海洛因依赖者脑底动脉血流动力学检测

The Detection of the Cerebral Arterial Hemodynamics of Heroin Depender

为探讨海洛因对脑血流的影响和变化规律,我们对海洛因戒断者117人分别于戒断当日和六个月时采用德国EME公司3D-TCD探头频率为2.0MHz,对ACA、MCA,PCA的血流动力学进行了检测。戒断当日的脑血流结果显示:44.4%的ACA、MCA、PCA的平均血流速度在正常范围,42.7%平均血流速度加快,12.8%平均血流速度减慢。戒断六个月时复测结果表明:88人(75.2%)的脑血流恢复正常,12人(10.7%)脑血流速度虽仍然力口快但与戒断当日较相比却有好转,提示对多数人,在戒断六个月时药物对血管的影响已消除。禁戒征也随之消失,而少数脑血流仍不正常者禁戒征仍然存在。通过对复吸人员的调查分析中也可看出在戒断六个月时也均程度不同的存在着脱瘾症,这可能是复吸的原因之一。

The blood flow velocities of ACA, MCA and PCA in 117 abstinece patients were examined using 3D - TCD,the results were : at the day of the abstinece. the blood flow velocities increased in 50/117 cases (42. 5%), decreased in 15/117 cases (12. 8%), about 52/117 cases (44. 4%) with in normal level. At the six month of the abstience. the blood flow velocities recovered to normal in about 88 cases (75. 2%), only cases (10. 7%) remain were within high level but the blood flow velocities decreased obviously comparing the results of one day of the abstinece.
