Clinical Trial Summary

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.

Description:

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.

Intervention

Drug:
• Neostigmine
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.
• Normal saline
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.
