OBJECTIVE
To objectively record sleep patterns in intensive care unit patients using the Bispectral Index as an electroencephalographic measure of sleep and to determine if the sleep pattern is correlated with various clinical factors.
METHODS
Adult intensive care patients were recruited who were in the recovery phase of their illness and on minimal sedation. The sleep pattern was examined using an overnight recording of the patient's Bispectral Index and submental electromyogram.
RESULTS
Twenty-seven adult patients in a tertiary level general intensive care unit were enrolled. The sleep pattern was examined using an overnight recording of the patient's Bispectral Index and submental electromyogram. No intensive care unit patients showed a completely normal sleep pattern, but about half showed 40-90 min cyclical periods of slow wave sleep that approached a normal sleep pattern.
CONCLUSIONS
Traditional classifications of EEG sleep staging are deficient when used to describe sleep in intensive care unit patients.
目的
使用脑电双频指数作为睡眠的脑电图测量指标，客观记录重症监护病房患者的睡眠模式，并确定睡眠模式是否与各种临床因素相关。
方法
招募处于疾病恢复期且使用最低剂量镇静剂的成年重症监护患者。通过对患者的脑电双频指数和颏下肌电图进行整夜记录来检查睡眠模式。
结果
三级综合重症监护病房的27名成年患者入组。通过对患者的脑电双频指数和颏下肌电图进行整夜记录来检查睡眠模式。没有重症监护病房患者表现出完全正常的睡眠模式，但约一半患者表现出接近正常睡眠模式的40 - 90分钟周期性慢波睡眠。
结论
当用于描述重症监护病房患者的睡眠时，传统的脑电图睡眠分期分类存在不足。
