The Impact of Overnight Nutrition Support on Sleep and Circadian Rhythm Disruption in the ICU

Description

The purpose of this study is to determine whether modifying the timing of nutrition support from overnight to daytime enhances sleep quality, preserves circadian rhythms, and improves overall inflammation and cardiometabolic profiles in postoperative patients in the cardiac surgical ICU on enteral nutrition.
