Mixed
Postoperative sleep disturbances, characterized by fragmentation and loss of deep/REM sleep, significantly increase the risk of postoperative delirium, cardiovascular events, and delayed recovery.
Recognize that poor sleep after surgery is not just 'being tired' but a clinical risk factor for confusion (delirium) and heart issues. Advocate for sleep-promoting measures like minimizing night interruptions, using earplugs/eye masks, and discussing sleep aids with the medical team.
GoodSupportsHIGH confidence
Development of sleep disturbances produces harmful effects on postoperative patients, that is, leading to higher risk of delirium, increased sensitivity to pain, more cardiovascular events, and poorer recovery.
Why this rating
Based on a review of multiple studies including RCTs and cohort studies, though the paper itself is a review.
