突发性聋的发病时间规律与血液流变学的关系

目的探讨突发性聋患者的发病时间规律及血液流变学变化的内在联系。方法观察198例突发性聋患者的血液流变学指标，并与60例正常对照组的相关指标进行整体对比分析，探讨突发性聋与血液流变学之间的关系。仔细询问198例患者的发病时间，每2h为一个时间段，统计每时段的发病人数，观察各时间段发病的突发性聋患者的血液流变学变化，从而更精确的说明二者之间的关系。同时检测了30例突发性聋患者一昼夜3次的血液流变学指标，观察突发性聋患者1d中的血液流变学变化规律。结果突发性聋患者的血液流变学指标与对照组相比有多项差异有统计学意义。突发性聋患者一昼夜血液流变学变化以晨起时的血流变指标为最高。各时间段发病人数以上午4～8时发病者最多，二者占全部突发性聋患者的42．9％，其余10个时段每段发病人数均不超过总人数的9％；12时段的血液流变学指标，又以上午4～8时段发病者为最高。结论血液流变学异常与突发性聋的发病密切相关，与心脑血管疾病一致，其发病高峰亦在晨时4—8时，且血流变指标高的患者更容易在清晨发病。

Study of relationship between the onset time of sudden deafness and blood rheology

Objective To investigate the correlation of the onset time of sudden deafness and blood rheology using a large-scale retrospective study. Methods One hundred and ninety-eight patients of sudden deafness were examined with blood rheology and compared with 60 healthy people. Thirty patients were as subjects to study the circadian of blood rheology in order to search whether the blood rheology of morning was the highest. By divided 24 hours into twelve groups, each group contained two hours. Then the 198 patients were separated into twelve groups according to the time of onset. The blood rheology of each group was analyzed and compared with each other to observe which group was the highest. Results Most blood rheology index of the patients were higher than that of the healthy people. The onset time in most of the patients was during 4 am-8 am, but 45 patients during 4 am-6 am and 40 patients during 6 am-8 am, By analyzing and comparing the blood rheology of each group, the results showed that the blood rheology index in the group of 4 am-8 am was highest. And the blood rheology index of sudden deafness was highest in the morning. Conclusions There was a close relation between blood rhoology and sudden deafness. The peak time of onset was 4 am-8 am, and the patients whose blood rheology were the highest should be more predisposed to sudden deafness than the other patients.
