Meta Analysis
Melatonin for delirium prevention in hospitalized patients: A systematic review and meta-analysis.
Melatonin, a pineal gland hormone is reported to have a protective effect against delirium. This systematic review and meta-analysis explores the effect of melatonin and melatonin receptor agonist, ramelteon on delirium prevention in adult hospitalized patients. ⋯ Melatonin/ramelteon are associated with reduction in delirium incidence in hospitalized patients. However, this effect seems confined to surgical and ICU patients. The optimum dosage and formulation of melatonin, and treatment duration remain uncleared and open to further studies with larger sample sizes.
