早期体感诱发电位检测对脑出血患者肢体运动障碍程度及预后判断的研究

目的 探讨早期检测脑出血患者短潜伏期体感诱发电位（short-latency somatosensory evoked p otential,SLSEP）在判断肢体瘫痪程度及预后中的意义。方法 对62例天幕上脑出血患者在发病10d内检测SLSEP，根据SLSEP异常程度不同将患者分成轻度、中度及重度异常3组。在发病初期及发病后3个月，按改良受丁堡－斯堪的那维亚脑卒中量表中肢体运动功能部分（partial revised Edinburgh-Scandinavia Stroke Scale,PRESSS）对每位患者计算积分，并根据积分的多少将患者分为轻度、中度及重度瘫痪。结果 在发病初期及3个月后，不同程度SLSEP异常患者组间的PRESSS积分差异有显著性意义（P＜0.05）,SLSEP异常程度越严重，PRESSS积分越坑，肢体瘫痪越严重；按二种方法分组的实际一致率分别为74.19％及66.13％。结论 对脑出血患者早期检测SLSEP有助于判断瘫痪肢体运动障碍的严重程度及预后。

Study on early application of the somatosensory evoked potential in the judgement of limb movement disorder and its prognosis in the patients with cerebral hemorrhage

Objective To explore the significance of early application of short latency somatosensory evoked potential(SLSEP) recording in judging the extent of limb paralysis and its prognosis in the patients with cerebral hemorrhage. Methods Sixty two patients were submitted to SLSEP recording within 10 days after attack of supratentorial cerebral hemorrhage, and consequently divided into three groups based on SLSEP abnormality: slight, moderate and severe. These patients were assessed using partial revised Edinburgh Scandinavia Stroke Scale(PRESSS) at onset and at post stroke 3 months, respectively, and further classified as slight, moderate and heavy palsy according to PRESSS score. Results PRESSS score was statistically significant among three groups with different levels of SLSEP abnormality both at onset and in 3 months(P< 0.05 ). And the SLSEP abnormality was in direct proportion to the PRESSS score, as well as the severity of paralysis. Actual agreements of dividing groups through two methods were 74.19 % and 66.13 %. Conclusion early application of SLSEP recording has significant value for predicting the extent of paralytic limb and its prognosis in cerebral hemorrhage patients.
