Delirium

Brief summary

1) Feasibility, 2) tolerability and 3) exploratory efficacy, defined as: 1) Recruitment rate, protocol adherence (number of administered doses divided by number of planned doses), participant retention, follow-up completeness and effectiveness of blinding; 2) Local nasal adverse events (e.g., irritation, epistaxis) and incidence of hypoglycaemia, defined as the number of local nasal adverse events and hypoglycaemia events; 3) Delirium severity (DRS-R-98)
