E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective is to investigate if the administration of naloxon can reinduce secundary hyperalgesia areas after a first degree burn injury in volunteers |
Formålet er at undersøge om administration af naloxon, kan re-introducere sekundære hyperalgesi-arealer efter en førstegrads varmeskade hos frivillige forsøgspersoner. |
