NCT03283020

Brief Summary

The purpose of the study is to evaluate the impact of different bolus volumes and viscosity on remifentanil-induced swallowing dysfunction in healthy volunteers.Hence, whether swallowing tasks can be done safer during sedation by altering bolus volumes and viscosities will be revealed. Furthermore, the study will clarify underlying mechanisms (central vs. peripheral effects) of remifentanil-induced swallowing dysfunction. If methylnaltrexone reverses the remifentanil-induced effects on swallowing, this would suggest a dominant peripherally mediated mechanism.

Study Arms (2)

RemifentanilMNTX

ACTIVE COMPARATOR

Volunteers are given an intravenous infusion with remifentanil, with an effect-site target concentration of 3 ng/ml via a target-controlled infusion (TCI) pump. After a series of swallowing tests an intravenous injection of methylnaltrexone of 0,3 mg/kg is given.

Drug: RemifentanilMNTX

PlaceboMNTX

ACTIVE COMPARATOR

Volunteers are given an intravenous infusion with saline 0,9%. After a series of swallowing tests an intravenous injection of methylnaltrexone of 0,3 mg/kg is given.

Drug: PlaceboMNTX

Interventions

Remifentanil infusion TCI 3 ng/ml, Methylnaltrexone injection 0.3 mg/kg

Also known as: Methylnaltrexone, Remifentanil, Relistor, Ultiva
