Study: NCT04948359

Intervention type: OTHER
Intervention: Group I (The patients intubated with cuffed ETT of ID number 4.5)
Description: Groups are classified according to endotracheal tube ID numbers. Inflating the endotracheal tube cuff with more than normal volume leads to decreased capillary blood flow and mucosal damage, while inflating the endotracheal tube cuff with less than normal volume leads to insufficient ventilation of the patient and an increase in the risk of pulmonary aspiration. The cuff pressure safety range is recommended between 20-30 cmH2O to prevent gas leakage and the risk of aspiration. We aimed to determine the optimal cuff volume that ensures airway safety in pediatric patients intubated with a 4.5 size inner diameter (ID) endotracheal cuff tube. Choosing the appropriate tube for endotracheal intubation is of great importance, especially in children. In our study, the transverse diameter of the subglottic airway will be measured by USG for the selection of the appropriate ETT to be used for each patient (the formulas for the selection of ETT in the literature will be used)

Intervention type: OTHER
Intervention: Group II (The patients intubated with cuffed ETT of ID number 5.0)
Description: Groups are classified according to endotracheal tube ID numbers. Inflating the endotracheal tube cuff with more than normal volume leads to decreased capillary blood flow and mucosal damage, while inflating the endotracheal tube cuff with less than normal volume leads to insufficient ventilation of the patient and an increase in the risk of pulmonary aspiration. The cuff pressure safety range is recommended between 20-30 cmH2O to prevent gas leakage and the risk of aspiration. We aimed to determine the optimal cuff volume that ensures airway safety in pediatric patients intubated with a 5.0 size inner diameter (ID) endotracheal cuff tube. Choosing the appropriate tube for endotracheal intubation is of great importance, especially in children. In our study, the transverse diameter of the subglottic airway will be measured by USG for the selection of the appropriate ETT to be used for each patient (the formulas for the selection of ETT in the literature will be used)
