Design outcomes

Primary

Measure	Time frame
Tracheal tube cuff pressure Measurements. Timepoint: Based on different time intervals (T1 at the beginning before inserting the probe, T2. TEE, the maximum pressure during the insertion of the TEE probe. T3, 5 minutes after inserting the TEE probe, and T4, the maximum pressure during the TEE. T5, 5 minutes after the completion of the TEE) . Method of measurement: Manometer (Mallinckrodt).;Airway Pressure Measurements. Timepoint: Peak and mean airway pressures were continuously monitored, intraoperatively,fashion using a pressure transducer connected to the “Y” piece of the anesthesia circuit. Method of measurement: calibrated pressure transducers (TruWave PX600; Edwards Lifesciences, Irvine, CA).	—

Measure	Time frame
Adjusting the cuff pressure to prevent complications such as sore throat and hoarseness after surgery. Timepoint: immediately at the beginning and every minute after the surgery. Method of measurement: It will be done by an anesthesiologist using a standard manometer.	—
