脑卒中急性期空腹胃电图动态变化分析

Feature of Fasting Cutaneous Electrogastrogram in Acute Stroke

目的观察脑卒中患者急性期空腹胃电图参数的动态变化,并探讨其相关发生机制。方法应用体表胃电图检测127例急性脑卒中患者入院24 h及入院1周时空腹胃电参数变化,并与34名健康对照组相对比。结果与正常组相比,脑卒中患者入院24 h胃窦及胃体部胃电振幅明显降低,入院1周时两部位胃电振幅则升高接近正常水平。胃窦及胃体部两不同时间的胃电频率与正常组相比无统计学意义。同时,脑出血患者入院24 h胃窦及胃体部的胃电振幅与正常组相比均明显降低(P<0.05),入院1周时已升高至正常水平。而脑梗死患者胃窦及胃体部两不同时间胃电振幅与正常组相比均无统计学意义。结论脑卒中患者急性期胃窦、胃体部的蠕动频率未见明显改变,而胃窦、胃体部的蠕动强度受到抑制,且不同性质的脑卒中类型对胃动力的影响亦不相同,其中脑出血患者胃窦、胃体部的蠕动强度降低尤为明显。

Objective To observe the dynamic features of fasting cutaneous electrogastrogram（EGG） parameters in patients（pts） with acute stroke.Methods The fasting cutaneous EGG parameters of 24 hours and 1 week after admission were measured in 127 pts with acute stroke,compared with those of 34 control cases.Results Compared with the normal group,the gastric electrical amplitudes in the gastric antrum and the gastric body at 24 hours after admission were significantly lower,while that in two parts at 1 week after admission were elevated and close to normal.The EGG frequencies of the gastric antrum and the gastric body were no significant difference compared with the normal group.At the same time,the gastric electrical amplitudes of the gastric antrum and the gastric body was distinctly decrease in pts with cerebral hemorrhage and the healthy at 24 hours after admission,while it was elevated to normal level at 1 week after admission.The fasting EGG parameters in pts with acute cerebral infarction were no obvious difference at different times compared with the normal group.Conclusion There were no changes of the frequencies of peristalsis of the gastric antrum and the gastric body significantly in the acute phase of stroke.The intensity of gastric peristalsis was significantly restrained,and in pts with cerebral hemorrhage was lower than that in other groups significantly.
