ICU sleep study: does checking patients every hour or every two hours matter?
NCT ID NCT05864300
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 1 time
Summary
This study looks at how often nurses should check on people in the ICU after they have had a brain aneurysm treated. The goal is to see if checking every hour versus every two hours affects how well patients sleep. Thirty adults who had a planned aneurysm coiling will take part, and their sleep will be measured overnight using brain wave monitors.
