Sleep-disrupting effects of nocturnal nursing interventions in intensive care unit patients: A systematic review

An aromatherapy massage intervention on sleep in the ICU: A randomized controlled feasibility study

We conducted a feasibility randomized controlled trial exploring the effect of aromatherapy massage on sleep in critically ill patients. Patients were randomized to receive aromatherapy massage or usual care, and feasibility of recruitment and outcome data completion was captured. Sleep (depth) was assessed through Bispectral Index monitoring and self/nurse-reported Richards-Campbell Sleep Questionnaires, and the Sleep in the ICU Questionnaire. Thirty-four patients participated: 17 were randomized to aromatherapy massage and 17 to control. Five participants who received the intervention completed outcomes for analysis (alongside eight controls). A larger study was deemed unfeasible in this population, highlighting the value of testing feasibility of complex interventions, such as massage for sleep in ICU.

Recent Progress in Long-Term Sleep Monitoring Technology

Sleep is an essential physiological activity, accounting for about one-third of our lives, which significantly impacts our memory, mood, health, and children's growth. Especially after the COVID-19 epidemic, sleep health issues have attracted more attention. In recent years, with the development of wearable electronic devices, there have been more and more studies, products, or solutions related to sleep monitoring. Many mature technologies, such as polysomnography, have been applied to clinical practice. However, it is urgent to develop wearable or non-contacting electronic devices suitable for household continuous sleep monitoring. This paper first introduces the basic knowledge of sleep and the significance of sleep monitoring. Then, according to the types of physiological signals monitored, this paper describes the research progress of bioelectrical signals, biomechanical signals, and biochemical signals used for sleep monitoring. However, it is not ideal to monitor the sleep quality for the whole night based on only one signal. Therefore, this paper reviews the research on multi-signal monitoring and introduces systematic sleep monitoring schemes. Finally, a conclusion and discussion of sleep monitoring are presented to propose potential future directions and prospects for sleep monitoring.
