Overview
Brief Summary
The aim of this study will be to test the accuracy of Sonography in determining the endotracheal tube size in pediatric patients whether cuffed or un-cuffed.
Detailed Description
* Children's tracheas have traditionally been intubated with un-cuffed tracheal tubes (TT) due to differences between adult and pediatric sub-glottic anatomy and fears that cuffs may lead to mucosal damage and subglottic stenosis. Despite this, cuffed TTs are increasingly used in pediatric anesthesia. Over the last 20 years, evidence suggests that cuffed TT may have advantages over un-cuffed, and are associated with at least similar, if not superior, airway outcomes when compared with un-cuffed TT in children. * Formulas based on age and height often fail to reliably predict the proper endotracheal tube (ETT) size in pediatric patients. Visualization of the pediatric subglottic airway diameter by ultrasonography (USG) can enable a practitioner to better predict ETT size, preventing unnecessary tube changes and airway trauma. Also, Visualization of the transvers diameter of epiphyseal end of distal radius by ultrasonography (USG) has been recently investigated and can enable a practitioner to better predict ETT size. Recent reports suggest that the diameter of the subglottic upper airway can be determined by ultrasonography in healthy young adults and pediatric patients . However, the extent to which ultrasonography by these two measurements can predict optimal ETT size in pediatric patients remains under investigation.
