earplugs in ICU

Q: Use of earplugs may decrease the incidence of delirium in ICU patients?

A) True
B) False


Answer: A

At least one randomized trial has shown that using earplugs at night is associated with a lower incidence of delirium in ICU. This is probably due to decrease noise pollution and improved physiologic sleep. This effect can further be enhanced by supplementing other endeavors like avoiding elective nursing interventions at night hours, and prescribing medications during awake hours.
