Melatonin for Prevention of Post- Operative Delirium Pilot Study Protocol

Withdrawn before enrolling · Phase 4 · Has a placebo group

Conditions studied: Delirium

In brief

To test the efficacy of melatonin compared to placebo in preventing post-operative delirium and reduction in intensity or duration of delirium in individuals 65 years of age and older who undergo orthopedic surgery after low energy lower extremity fractures (LELEF). Biomarkers may play important roles in the detection, prediction and management of delirium especially in frail elderly individuals. Predictive biomarkers may help characterize an individual's susceptibility to delirium and thereby help specialized treatment, care and management of such individuals during their hospitalization. They may also help predict treatment response to a specific modality and help in selection of such modality. Recent studies performed in the UK and published in 2011 have measured plasma cholinesterase activity and determined that these levels were lower in patients who developed delirium compared with remaining subjects. Other studies have indicated that CRP may also have a role in delirium prediction as they have found that CRP measured on admission to an ICU had predictable changes that occurred within 24 hours that in turn were predictors of delirium. One the aims of the study is to compare the predictive and treatment response values of groups of biomarkers that have been hypothesized to be of predictive value.

You may not qualify if…

• Patients with previous adverse reaction or side-effects to melatonin
• Inability or unwillingness of individual or legal guardian/representative to give written informed consent.
• Inability to communicate in English
• Patients with a Montreal Cognitive Assessment (MoCA) score of below 7 will not be included in the study because of their inability to give informed consent at that stage. This score is approximately 2 standard deviation below average score for Alzheimer's Dementia.
