60例2型糖尿病病人的BAEP变化

目的　观察 2型糖尿病患者BAEP的变化。方法　随机选取 60例 2型糖尿病患者检查其BAEP ,根据其有无周围神经损害分为A、B两组 ,另设 3 0例非 2型糖尿病患者作为对照组。结果　 2型糖尿病患者的BAEP的Ⅲ、Ⅴ波潜伏期为 4.0 5± 0 .2 1ms ,6.0 8± 0 .2 4ms。对照组BAEP的Ⅲ、Ⅴ波潜伏期为 3 .83± 0 .18ms ,5 .87± 0 .2 1ms。两者比较有显著性差异 (P <0 .0 0 1)。I-Ⅲ、Ⅲ -Ⅴ、I-Ⅴ峰间期在 2型糖尿病患者与正常组分别为 2 .2 8± 0 .19msvs 2 .0 4± 0 .2 5ms,2 .0 7± 0 .2 5msvs 1.84± 0 .2 1ms ,4.3 1± 0 .2 1ms,vs 4.12± 0 .2 6ms,两者相比有显著性差异 (P <0 .0 0 1)。在糖尿病患者中有周围神经损害的BAEP测值各参数 ,均明显高于无周围神经损害患者 ,P <0 .0 5～ 0 .0 0 1。结论　 2型糖尿病患者的BAEP的Ⅲ、Ⅴ波潜伏期与正常组相比明显延长 ,且有周围神经损害比无周围神经损害的 2型糖尿的患者的BAEP异常率明显增高

The BAEP Changes in Type 2 Diabetics

Objective To observe the brainstem auditory evoked porentil(BAEP)changes in type diabetics (T2DM). Methods 60 cases type diabetics who underwent BAEP were categorized into group A (with neuropathies)and group B (without neuropathies).30 non-T2DM patients healthy persons were as normal control group.Results The Ⅲ wave and Ⅴ wave latent periods of BAEP were 4.05±0.21 ms and 6.08±0.24 ms in T2DM group and 3.83±0.18 ms and 5.87±0.21 ms in control group,respectively(P<0.001).I-Ⅲ,Ⅲ-Ⅴ,I-Ⅴ interspike intervals in T2DM were longer than those in normal controls(2.28±0.19 ms VS 2.04±0.25 ms,2.07±0.25 ms Vs 1.84±0.21 ms,4.31±0.21 ms VS 4.21±0.26 ms,P<0.001).In T2DM,BAEP value for each parameter was srynificantly higher in those with peripheral neruopathier than that in those without peripheral neuropathies (P<0.05～0.001).Conclusions The latent periods of Ⅲ wave and V wave of BAEP are prolonged significantly in T2DM than those in normal controls.The abnormal rate is even higher in T2DM with peripheral neuropathies.
