Recruiting

• Conditions: Sore Throat; Tracheal Tubes With an Inner Diameter of 6.0mm; Tracheal Tubes With an Inner Diameter of 6.5mm; Tracheal Tubes With an Inner Diameter of 7.0mm

• Registration Number: NCT06967896
• Lead Sponsor: Anqing Municipal Hospital

Brief Summary

Objective:Compare whether the use of tracheal catheters of models 6.0 and 6.5 causes less sore throat in women after thyroid surgery compared with the traditional use of model 7.0 tracheal catheters.Methods: Investigators enrolled 180 female patients with American Society of Anesthesiologists (ASA) physical status I and III, aged 18-65 years, and scheduled for elective undergoing thyroid surgery with general anesthesia. The participants were randomly assigned into three groups(n=60 each group):Group A: Tracheal catheter group with an inner diameter of 6.0mm, Group B: Tracheal catheter group with an inner diameter of 6.5mm, Group C: Tracheal catheter group with an inner diameter of 7.0mm.The incidence and severity of postoperative sore throat were recorded in three groups at 1 h, 6 h, 24 h and 48 h after operation.
