Summary

This study uses ultrasound to measure diaphragm function in children aged 1-12 with suspected obstructive sleep apnea who are having surgery. Researchers will compare these children to those without sleep apnea to see if diaphragm movement differs. The goal is to better understand breathing issues in these young patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Children aged 1-12 years who are followed at the Department of Otolaryngology of Istanbul University Istanbul Faculty of Medicine and are scheduled for surgery will be included in this study. Participants will be assessed preoperatively using the Pediatric Sleep Questionnaire (PSQ). Children who answer "yes" to at least 8 of the 22 items and are scheduled to undergo adenotonsillectomy will be assigned to the obstructive sleep apnea syndrome (OSAS) group, whereas children who answer "yes" to fewer than 8 items and are scheduled to undergo elective non-airway-related otolaryngologic surgery will be included in the control group. Only children with ASA physical status I-II who meet the inclusion and exclusion criteria and for whom informed consent has been obtained will be enrolled.

Ages

1 year to 12 years
