睡眠呼吸暂停综合征患者眼震电图的改变及意义

Change and significance of ENG in patients with sleep apnea syndrome

目的 探讨睡眠呼吸暂停综合征 (SAS)患者的眼震电图 (ENG)改变及临床意义 .方法 对 36例 SAS患者进行了视眼动系统反应、自发性眼震、冷热试验、位置性眼震试验检查 .结果 视眼动系统反应异常者 14例 (4 4.4% ) ,7例(19.3% )记录到自发性眼震 ,30例 (83.3% )引出位置性眼震 ,SAS患者 SPV比较对照组有显著性差别 (P<0 .0 5 ) .冷热试验 2 0例出现异常 .结论 SAS患者病变可累及前庭及其中枢 。

AIM To investigate the change of electronystagmography (ENG) in sleep apnea syndrome (SAS) patients and its clinical significance. METHODS ENG was used to examine 36 patients with SAS. Thirty healthy people were taken as control group. The differences of ENG parameters between these two groups were checked. RESULTS The abnormal optokinetic reflex (OKR) in 14 (44.4%) patients, pathological spontaneous nystagmus (SN) in 7 patients ( 19.3% ) and positional nystagmus (PN) in 30 (83.3%) patients were found. The slow phase velocity of PN in SAS was significantly higher than that in control ( P <0.05). Therewere 20 patients with decreased function or paralysis of semicircular cannals in caloric test. CONCLUSION These results suggest that the SAS may influence the vestibule and vestibular center and ENG could be used as a objective test in SAS.
