Study arms

  • Active comparator
    rocuronium 0.45 - neostigmine

    when anesthetic induction, inrocuronium 0.45 mg/kg will be administered for muscle relaxation. When the end of operation, a injection of neostigmine or sugammadex will be administered.

    Other: Injection of neostigmine or sugammadex

  • Active comparator
    rocuronium 0.9 - sugammadex

    When anesthetic induction, rocuronium 0.9 mg/kg will be injected to rocuronium 0.9 - sugammadex group for muscle relaxation. When the end of operation,, a injection of neostigmine or sugammadex be administered.

    Other: Injection of neostigmine or sugammadex

Interventions

  • OtherInjection of neostigmine or sugammadex

    At anesthetic induction, rocuronium 0.45 to rocuronium 0.45 - neostigmine group or rocuronium 0.9 mg/kg to rocuronium 0.9 - sugammadex group will be injected for muscle relaxation. During surgical procedure, we will monitor train of four (TOF) using nerve stimulator. After operation, neostigmine 50 mcg/kg or sugammadex 4 mg/kgl be injected.

    Also known as: neostigmin or sugammadex

What researchers measure

Primary outcomes

  1. Laryngoscopic Score

    Definitions for evaluation of Laryngoscopycondition. : Easy = jaw relaxed, no resistance to blade insertion, fair = jaw not fully relaxed, slight resistance to blade insertion, difficult = poor jaw relaxation, active resistance of the patient to laryngoscopy. Variables Excellent Good Poor

    Time frame: At the beginning of surgery, the surgeon rated the laryngoscopy condition

Secondary outcomes

  1. Recovery Time From Neuromuscular Blockade

    We measured recovery time ffrom the injection of neostigmine or sugammadex to TOF ratio 0.9

    Time frame: from the injection of neostigmine or sugammadex up to 30 minutes
