Research Progress on Non-Pharmacological Sleep Interventions in the Prevention of Delirium in Postoperative ICU Patients

Sleep disorders are a significant risk factor for delirium in postoperative ICU patients. Sleep interventions can effectively reduce the incidence of delirium, but most studies have focused on pharmacological approaches. Non-pharmacological sleep interventions have shown significant efficacy in preventing delirium in postoperative ICU patients. This review examines non-pharmacological sleep interventions for delirium prevention in ICU patients, aiming to provide a reference for the prevention of delirium in postoperative ICU patients.
