Standardized Sleep Bundle for Cardiac Surgery Patients

Recruiting now · Not applicable

Conditions studied: Sleep

In brief

The goal of this clinical trial is to evaluate the feasibility of using a standardized sleep bundle in adults undergoing cardiac surgery. The main questions it aims to answer are: 1. Can eligible participants be recruited and retained in the study? 2. Can participants follow the study procedures, including using sleep aids and completing daily assessments? 3. Can sleep and other clinical data be reliably collected during the hospital stay? Researchers will compare participants who receive the sleep bundle to participants who receive usual postoperative care. Participants will: * Use non-drug sleep aids, including a sleep mask, ear plugs, and a noise machine (sleep bundle group only). * Take sleep medications if needed, following a stepwise protocol (sleep bundle group only). * Complete daily sleep assessments using the Richards-Campbell Sleep Questionnaire (RCSQ). * Wear a Fitbit device at night to track sleep. * Follow usual postoperative care routines (control group) The study will also collect and describe data on sleep duration, nighttime awakenings, subjective sleep quality, incidence of postoperative delirium, and hospital length of stay to inform the design of a future larger trial.

Run-in Period Exclusions:
After enrolment and before randomization, participants will be monitored for specific postoperative criteria. Those meeting any of the following criteria will be withdrawn prior to randomization.
Radial artery harvest required (unable to place Fitbit device on the wrist contralateral to the arterial monitoring line).
Prolonged intubation or sedation (> 48 hours) post-surgery.
