The goal of this observational study is to learn about whether the loss-of-resistance syringe technique is beneficial when adjusting endotracheal cuff pressure in pediatric patients. The main questions it aims to answer are: * Is the loss of resistance syringe technique useful when adjusting endotracheal cuff pressure in pediatric patients? * Is there a difference between the measurements of two different cuff manometers used in the clinic, if so, what is the safety margin between the two manometers? The participants who will be operated under general anesthesia will be anesthetized with the standard anesthesia method, the cuffs of the endotracheal tubes will be inflated with an epidural loss of resistance syringe, the syringe piston will be released, and then the syringe piston will be pushed back with oscillation. Then, cuff pressures will be measured and recorded with a cuff manometer (VBM Cuff Pressure Gauge) and an electronic injector measuring cuff pressure (AG Cufill).
