为探索低血糖对脑损伤的危害及低血糖性偏瘫的特征及预后。对象与方法:全部偏瘫患者急查血糖≤2.8mmol/L并经给与葡萄糖输注后偏瘫迅速或较短时间缓解的患者为观察对象;21例偏瘫患者入院后急查头部CT显示18例正常,2例轻度脑萎缩1,例陈旧性基底节梗塞;入院后24～48小时内对18例头部CT正常的患者,其中8例复查头部MRI,2例可见脑皮层双侧顶叶、颞叶T1WI正常、T2WI高信号影。1例可见双侧枕叶、海马、黑质T1WI斑点状低信号、T2WI高信号影。结果:全部病例经积极治疗,血糖水平恢复正常后,偏瘫迅速或较快时间缓解。其中3例头部MRI于T1及T2信号异常的患者,经住院5～7天后复查MRI均恢复正常。
To explore the hypoglycemic effects on brain injury and the characteristics and prognosis of hypoglycemic hemiplegia. Subjects and Methods: All patients with hemiplegia urgently check blood sugar ≤2.8mmol / L and given to patients with acute or late hemiplegia after glucose infusion were observed; 21 patients with hemiplegia after admission emergency head CT showed 18 cases Normal, 2 cases of mild brain atrophy 1 case of old basal ganglia infarction; 24 to 48 hours after admission to 18 cases of normal head CT patients, including 8 cases of recurrent head MRI, 2 cases visible cortical bilateral top The temporal lobe T1WI normal, T2WI high signal shadow. One case showed bilateral occipital lobe, hippocampus, substantia nigra T1WI spotted low signal, T2WI high signal. Results: All cases were actively treated, blood glucose levels returned to normal, rapid or faster hemiplegia time to ease. Three cases of head MRI in T1 and T2 signal abnormalities patients, after 5 to 7 days after hospital review MRI returned to normal.
