超声-中频电治疗脑梗塞的临床观察

Clinical research of ultrasound-medium frequency current therapy on cerebral infarction

按国家统一制定的诊断标准,明确诊断为脑梗塞患者164例,按均衡配对原则随机分为两组,每组82例。一组采用临床常规药物治疗,另一组采用临床常规药物并超声一中频电治疗。均于一个疗程后按统一疗效标准判断疗效,两组疗效差异有显著性(P<0.05)。观察证明,病程越短疗效越高,年龄越大疗效越低,病灶浅者疗效较好。本组病例的脑血流图结果提示并用超声-中频电治疗组脑血流明显改善,治疗部位(患侧)的流入时间、主峰角和波幅等三项指标的变化差异均有非常显著性(P<0.01)。并讨论了超声-中频电治疗脑梗塞适应证的选择、剂量与波型及其作用机制。

In accordance with the unified diagnostic criterion formulated by the state,164 cases were exactly diagnosed as cerebral infarction,they were,randomly and equivalently,divided into the treatment group which were treated with ultrasound-medium frequency current and clinical routine medication,and the control group which were only used the clinical routine medication.After one course of treatment,the curative effects were compared by Ridit analysis between both groups.The re- sult showed that the curative effect of the treatment group was remarkably superior to that of the con- trol group(P<0.05).Moreover,the relationship between the curative effect and duration of illness or the cerebral infarct region was analysed.The analysis showed that the shorter the course of disease is, the higher the curative effect is;the more superficial the focus,the higher the curative effectis is;the older the patients are,the lower the curative effect is.There were a significant differences (P<0.05). At the same time,the cerebral blood flow had been improved by rheoencephalogram test in treatment group.The rheoencephalogram indicated that the inflow time,highest peak angle and wave amplitude of affected region obtained obvious change and difference.Lastly,the dose,indication and waveform of ultrasound-medium frequency current to cerebral infarction,and its mechanism are also discussed in the paper.
