About this trial

This is an interventional prevention trial for Sore Throat focused on measuring muscle relaxant

Eligibility Criteria

20 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Requirement for mechanical ventilation under general anesthesia

Exclusion Criteria:

  • Hoarseness and sore throat existed before surgery
  • Upper respiratory infection
  • Known or predicted difficult airway
  • Liver, renal disease
  • Requirement of postoperative ventilator care
  • the operation within 2hrs
  • Laparoscopic surgery
  • Other positions except supine during surgery

Arms of the Study

Arm 1

Arm 2

Arm Type

Active Comparator

Experimental

Arm Label

Moderate muscle relaxation

Deep muscle relaxation

Arm Description

Rocuronium is administered to maintain moderate relaxation during operation. This is conventional muscle relaxation level of this institute.

Rocuronium is administered to maintain deep relaxation during operation.

Outcomes

Primary Outcome Measures

Overall incidence of postoperative sore throat
The overall cumulative incidence of postoperative sore throat is assessed in the 24-hr evaluation period

Secondary Outcome Measures

The incidence of postoperative sore throat
The presence of sore throat is assessed.
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]).
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).
Postoperative analgesic consumption
The amount of patient-controlled analgesia and other analgesic medication used

5. Study Description

Brief Summary
Investigators assess and compare postoperative sore throat and hoarseness in the group maintaining moderate relaxation and deep relaxation during operation.
Detailed Description
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.
