About this study

For successful intraoperative neuromonitoring (IONM), adequate reversal of neuromuscular blocking agent is a prerequisite in thyroid surgery with .

The aim of this study is to investigate the feasibility of neostigmine just after tracheal intubation on the IONM in thyroid surgery.

This study will be performed as a randomized controlled trial with two groups (N group: neostigmine group and NS group: normal saline group).

For the N group, neostigmine (0.03 mcg / kg) and glycopyrrolate with a 5:1 ratio will be administered just after tracheal intubation.

For the NS group, normal saline with a same volume of the N group will be administered just after tracheal intubation.

For all patients of two groups, investigators evaluate the quality of signal of IONM during the surgery.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • open thyroid surgery with intraoperative neuromonitoring

Exclusion criteria

  • refusal to participate in the study
  • rocuronium should not be used (e.g. renal dysfunction patient)

Treatment and study plan

Neostigmine

Drug

For the N group, neostigmine (0.03 mcg / kg) and glycopyrrolate with a 5:1 ratio will be administered just after tracheal intubation.

Investigators evaluate the quality of signal of IONM during the surgery.

Other names: N group

normal saline

Drug

For the NS group, neostigmine normal saline (0.09 cc/kg; the same volume of the group N) will be administered just after tracheal intubation.

Investigators evaluate the quality of signal of IONM during the surgery.

Other names: NS group

Primary outcomes

  1. Time to recovery of cricothyroid muscle twitching

    Time frame: perioperative

    Time from the rocuronium administration to recovery of cricothyroid muscle twitching

Secondary outcomes

  1. amplitude of EMG for V1

    Time frame: During surgery

    micro-volts (uV), Electromyography amplitude of the vagus nerve before tumor manipulation

  2. amplitude of EMG for R1

    Time frame: During surgery

    micro-volts (uV), Electromyography amplitude of the recurrent laryngeal nerve before tumor manipulation

  3. amplitude of EMG for R2

    Time frame: During surgery

    micro-volts (uV), Electromyography amplitude of the recurrent laryngeal nerve after tumor removal

  4. amplitude of EMG for V2

    Time frame: During surgery

    micro-volts (uV), Electromyography amplitude of the vagus nerve after tumor removal

  5. number of patients with involuntary movements disrupting surgery

    Time frame: During surgery

    number, number of patients who move involuntarily during surgery, which disrupt and pause the surgery to prevent harmful events, such as tracheal injuries by a sharp surgical devices during the surgery
