亚谵妄综合征相关研究进展

Research progress on Subsyndromal Delirium

亚谵妄综合征患者常表现出意识水平波动、注意力不集中、感知觉障碍、思维紊乱中的部分症状,虽达不到完全谵妄的诊断标准,却严重影响临床预后,导致患者病死率增加、住院时间及机械通气时间延长,因此受到研究者广泛关注。本文将从亚谵妄综合征的流行病学、病因学、诊断学、治疗学以及疾病预后角度对相关研究进行综述,旨在为未来国内对亚谵妄综合征进行更好地探索、监测、识别患者意识状态,提供有针对性的医疗护理措施,改善亚谵妄综合征患者预后提供依据。

Subsyndromal Delirium （SSD） patients often show symptoms such as fluctuation of consciousness level, inattention, perceptual and thinking disorders. They don＇t meet the diagnostic criteria of full delirium, but their clinical outcomes will be impacted by SSD severely. SSD will lead to higher mortality, prolonged length of hospital stay and duration of mechanical ventilation.SSD has been highly concerned by researchersin the world. This article reviewed the epidemiology, etiology, diagnosis, treatment and clinical outcomes of SSD, so that to provide evidence for nurses to recognize and monitor patients＇ consciousness level in an effective way.
