NCT02054468

Brief Summary

This study is designed to determine the effective-doses ED-50 and ED-95 (the doses required for a 50% and 95% twitch inhibition, respectively) of the non-depolarizing muscle relaxant rocuronium after single-shot or steady-state propofol anesthesia in a clinical setting.

Outcome Measures

Primary Outcomes (2)

  • ED-50 of rocuronium

    The primary outcome measure is the 1) ED-50 of rocuronium during anesthesia induction with propofol and after steady-state propofol anesthesia

    Anesthesia time during their surgical procedure (=arrival in the OR until discharge from the post-anesthesia care unit), ca. 180min

  • ED-95 of rocuronium

    The primary outcome measure is 2) the ED-95 of rocuronium during anesthesia induction with propofol and after steady-state propofol anesthesia

    Anesthesia time during their surgical procedure (=arrival in the OR until discharge from the post-anesthesia care unit), ca. 180min

Secondary Outcomes (1)

  • Pharmacodynamics of rocuronium (composite outcome measure)

    Anesthesia time during their surgical procedure (=arrival in the OR until discharge from the post-anesthesia care unit), ca. 180min

Study Arms (2)
