额叶损伤后睡眠障碍的多导睡眠脑电图研究

目的 探讨额叶脑伤患者的多导睡眠图异常改变.方法 采用多导睡眠仪对16例额叶脑伤后伴睡眠障碍患者(脑伤组)和20例健康体检者(对照组)进行整夜睡眠描记.结果 脑伤组与对照组比较 ,睡眠潜伏期延长 ,睡眠时间及慢波睡眠时间均显著缩短 ,快速眼动期(REM )时间、REM周期数比较差异有统计学意义( P＜0 .05 ) ,REM 潜伏期、REM 强度、密度比较 ,差异无统计学意义(P＞0 .05).结论 额叶脑伤患者多导睡眠图变化以REM睡眠时间延长及周期数缩短为主.

Study on polysomnography in patients with sleep disorder induced by traumatic frontal lobe injury

Objective To explore the abnormal changeof the polysomnography(PSG) in the patientwith traumatifrontal lobe injury .MethodTotally 16 patientwith traumatifrontal lobe injury accompanying sleep disorde(brain traumgroup) and 20 individualof physical examination (control group) were performed the whole nighPSG .ResultCompared with the control group ,the incubative stage of sleep in the brain traumgroup waprolonged ,while the sleep time and slow wave sleep time were shortened .The rapid eye movemen(REM) time and the periodicity of REM had statistical differencebetween the two group,buthe REM incubative stage ,density and intensity of REM had no statistical differencebetween the two goup.Conclusion The changeof PSG in the patientwith traumatifrontal lobe injury are dominated by the extension of the REM time and the shorten-ing of REM periodicity .
