What this Trial Is About
This research aims to compare whether using different sizes of tracheal catheters causes less sore throat in women after thyroid surgery. It involves female patients aged 18 to 65 years with physical health status ranging from ASA I to III, all scheduled for thyroid surgery under general anesthesia. The study focuses on evaluating sore throat incidence and severity following the procedure. Participants are randomly assigned to one of three groups, each receiving a tracheal catheter with a different inner diameter: 6.0 mm, 6.5 mm, or the traditional 7.0 mm size. The study monitors how each catheter size affects postoperative sore throat at multiple time points after surgery, specifically at 1 hour, 6 hours, 24 hours, and 48 hours. During the study, researchers record the presence and severity of sore throat at these times to assess differences among the groups. The trial includes women undergoing elective thyroid surgery under general anesthesia who meet the eligibility criteria. The study is expected to run until October 2026, with participant involvement mainly around the surgery and follow-up sore throat assessments.
