Investigators assess and compare postoperative sore throat and hoarseness in the group maintaining moderate relaxation and deep relaxation during operation.
In this sturdy, the deep block is applied when the surgeon requests for deep muscle relaxation to improve surgical field condition in the surgery such as laparotomy known that the deep block is helpful and in the other surgeries, the moderate block is maintained. The investigators assess the postoperative sore throat and hoarseness and compare the effect of muscle relaxation depth in the deep block group and moderate block group in terms of the incidence and severity of postoperative sore throat and hoarseness.

RECRUITINGOverall incidence of postoperative sore throat
The overall cumulative incidence of postoperative sore throat is assessed in the 24-hr evaluation period
Time frame: Within 24 hrs after operation
The incidence of postoperative sore throat
The presence of sore throat is assessed.
Time frame: At 1,6, and 24 hrs after operation
The severity of postoperative sore throat
The severity of sore throat is assessed by using a 100-point numerical ratig scale (NRS, 0 \[no pain\], 100 \[worst pain imaginable\]).
Time frame: At 1,6, and 24 hrs 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 hrs after operation
Postoperative analgesic consumption
The amount of patient-controlled analgesia and other analgesic medication used
