1. Explanation of how to evaluate diaphragm muscle thickness:
a) the approximate time to perform the measurement is 20-30 seconds,
b) the measurement does not have an association with the operation or the surgery region, and
c) Ultrasonic measurement shall be made 4 times in total, basal, after intubation, before extubation and after extubation.
2. Medical doctor will administer the ultrasound.

Statistical methods / analysis
Descriptive statistics will be presented continuously variables as mean SD. X 2 tests will be used to assess differences in groups
for the categorical variables. Sensitivity, specificity, positive predictive
value (PPV) and negative predictive value (NPV) will be
calculated for ultrasound derived measurements of tdi in the groups in predicting
extubation success.

Summary
Brief summary
The use of ultrasonography in the operating room is increasing day by day. Ultrasonography is a method used to evaluate diaphragm thickness. There are publications that demonstrate the usefulness of evaluating diaphragm thickness, diaphragm function, and contribution to respiratory workload. Measurement of the diaphragm thickness is a parameter that can be used for decision making before mechanical ventilation and extubation. Adenotonsillectomy operations are frequently performed in the operating room between the pediatric age group. In these cases, which are operated and extubated at the end of the operation, the ratio of the diaphragm muscle thickness to the final inspiratory and final exhalation before extubation will be examined. We think that the determination of this ratio may be meaningful for the determination of the extubation time.
In this study, we plan to evaluate diaphragm thickness rates with USG in pediatric patients who underwent adenotonsillectomy operation and evaluate whether they provide extubation criteria in these patients.
