Investigators assess and compare postoperative sore throat and hoarseness in the group using the muscle relaxant and not using it during the operation.
The muscle relaxant is usually used during the operation to maintain moderate relaxation but, it can't be used in the surgery to need eletrophysiological monitoring during the operation. In this sturdy, the investigators assess the postoperative sore throat and hoarseness and compare the effect of muscle relaxant in the group using the muscle relaxant and not using it in terms of the incidence and severity of postoperative sore throat and hoarseness.
Study Type
OBSERVATIONAL
Enrollment
117
In the group to need the eletrophysiological monitoring during the operation, we don't inject muscle relaxant except anestheitic induction.

Overall cumulative incidence of postoperative sore throat
The incidence sore throat is assessed by the presence of sore throat
Time frame: Within 24 hr evaluation period after operation
Overall cumulative incidence of postoperative hoarseness
The incidence sore throat is assessed by the degree of hoarseness
Time frame: Within 24 hr evaluation period after operation
Incidence of postoperative sore throat
The incidence of sore throat is assessed by the presence of sore throat.
Time frame: At 1,6, and 24 hr after operation
Severity of postoperative sore throat
A 0-100 mm NRS is used to evaluate the severity of sore throat (0, no pain; 100, worst pain imaginable).
Time frame: At 1,6, and 24 hr after operation
Incidence and severity of postoperative hoarseness
Hoarseness is defined as a voice quality different from the preoperative voice and graded as follows: none (no hoarseness), mild (recognized by the patient), moderate (obvious to the investigator), and severe (aphonia).
Time frame: At 1,6, and 24 hr after operation
Post operative analgesic consumption
the amount of patient-controlled analgesia and other analgesic medication consumed
Time frame: within 24 hrs after operation
