Does Perineural Dexmedetomidine Prolong Duration of a Nerve Block?

• Status: Completed
• Trial end date: 2015-09-01
• Target enrollment: 0
• Participant gender: Male

Summary

Brief Summary: The aim of this trial is to investigate if dexmedetomidine prolongs the duration of an adductor canal block. By using healthy volunteers the investigators can perform a bilateral adductor canal block and thereby control for a systemic effect to clarify if the effect is actually peripheral or systemic. The investigators hypothesis is that dexmedetomidine as an adjunct to a local anaesthetic prolongs the duration of a peripheral nerve block by a peripheral mechanism.
