Is this trial a fit for you?

Likely a good fit

Ideal candidates are female patients aged 18-65 years scheduled for elective thyroid surgery under general anesthesia.

Probably not a fit

Patients with pre-existing throat conditions or those who have had previous throat surgeries may not benefit from this study.

What this trial studies

This observational study aims to compare the incidence and severity of postoperative sore throat in female patients undergoing thyroid surgery using three different models of tracheal catheters: 6.0mm, 6.5mm, and the traditional 7.0mm. A total of 180 female patients, aged 18-65 years and classified as ASA grade I-III, will be randomly assigned to one of the three groups, with 60 participants in each group. The study will assess sore throat outcomes at multiple time points post-surgery to determine which catheter model minimizes discomfort. The findings could provide insights into optimizing anesthesia practices for thyroid surgery.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative comfort for women undergoing thyroid surgery.

How similar studies have gone: While similar studies have explored tracheal catheter designs, this specific comparison of models in female thyroid surgery is relatively novel.
