Intranasal sufentanil for pre‐operative sedation

Sufentanil, a short-acting and potent narcotic agent, was studied as a premedicant administered by the nasal route. A total dose of 5 micrograms appeared to be too low, while either 10 or 20 micrograms was very effective in producing sedation. Side effects were minor. There appeared to be no differences between nose drops and spray. In a further study, sufentanil nose drops were compared with saline 0.9% in a double-blind fashion. Sedation of rapid onset but of limited duration was observed in the majority of patients who received sufentanil.
