Overview

The goal of this clinical trial is to find out whether applying Endotra Gel, a hyaluronic acid-based gel, to the endotracheal tube can help reduce sore throat and hoarseness after surgery. These symptoms are common after general anesthesia when a endotracheal tube is placed into the trachea. They can cause discomfort and affect patient recovery. The main questions this study aims to answer are: * Does Endotra Gel reduce the chance of having a sore throat after surgery? * Does it help improve hoarseness or coughing after surgery? Participants in this study will: * Undergo general anesthesia for breast cancer surgery * Be randomly assigned to one of two groups: * One group will receive Endotra Gel applied to the endotracheal tube before intubation * The other group will have standard care with no gel * Be monitored for sore throat, hoarseness, and coughing right after surgery and on the day after surgery * Answer questions about their symptoms and satisfaction with their recovery The results will help researchers learn whether using Endotra Gel during intubation can improve patient comfort and reduce airway irritation after surgery.

Outcomes

Primary Outcomes

Incidence and Severity of Postoperative Sore Throat

Postoperative sore throat (POST) will be assessed using a standardized 4-point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe) through direct patient interview. Assessment will be performed by blinded outcome assessors.

Time frame: Up to 1 hour after extubation at PACU

Secondary Outcomes

Incidence and Severity of Postoperative Hoarseness

Hoarseness will be evaluated using a 4-point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe) through patient interview. Evaluation will be performed by blinded assessors.

Time frame: Up to 1 hour after extubation at PACU and on postoperative day 1 (within 24 hours after surgery)

Incidence and Severity of Postoperative Cough

Postoperative cough will be assessed on a 4-point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe) through direct questioning. Evaluation will be conducted by blinded assessors.

Time frame: Up to 1 hour after extubation at PACU and on postoperative day 1 (within 24 hours after surgery)

Patient Satisfaction with Intubation Experience

Patient satisfaction regarding intubation-related discomfort will be evaluated using two structured questions: "Postoperative discomfort related to intubation interfered with daily life." "Overall, I am satisfied with the intubation experience." Each item will be rated on a 5-point Likert scale: 1 = Strongly agree, 2 = Agree, 3 = Neutral, 4 = Disagree, 5 = Strongly disagree. Responses will be collected on postoperative day 1 and analyzed as ordinal variables.

Time frame: On postoperative day 1 (within 24 hours after surgery)
