An observational study in Difficult Airway, sponsored by Istanbul University. Recruiting at 1 site in Turkey. Open to participants aged 1 Year to 12 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-05-09.
Sponsored by Istanbul University · Observational
This study was designed to assess the accuracy of ultrasonographic parameters in combination to clinical parameters in the prediction of difficult airway in pediatric population.
All patients underwent a standard airway examination and sonographic airway assessment preoperatively and the predictive values for difficult airway of these methods were recorded.
Difficult airway in a pediatric patient is associated with more stresful situation than adults. Therefore, various clinical airways parameters have been investigated in the prediction of difficult airway. Sonographic evaluation to predict difficult airway is still primitive especially in pediatrics.
Ultrasonography and clinical parameters have been shown to be used in predicting difficult airway, but there is no study showing which is a better predictor.
Istanbul University is the lead sponsor of 496 studies on the registry; 79 are open to participants now.
Of its 5 completed or terminated interventional studies of FDA-regulated products, 1 (20%) have results posted.
Counted across the registry records on this site, refreshed daily.
The patients, aged between 1-12 years, who required endotracheal intubation under general anesthesia for elective procedures were included in the study.
