Non-pharmacological Interventions for Sleep Promotion in the Intensive Care Unit

In this extensive review, the authors examined 30 studies, many of which were randomized controlled trails,  that evaluated the effects of non-pharmacological interventions for sleep promotion in patients admitted to the ICU who were 18 years of age or older.  In these studies, there were at total of 1569 patients.  The authors we able to review many interventions and their effects on sleep. They concluded that the quality of existing evidence pertaining to using non-pharmacological interventions for promoting sleep on critically ill adult patients was low or very low. However, they did find that earplugs or eye mask may have a small benefit on sleep and delirium in the ICU.
