Tracheostomy is a commonly performed intervention in patients requiring ventilatory support. The insertion of inappropriately sized tracheostomy tubes carries risk decannulation, tissue damage, difficulties, premature tube change or discomfort. Currently, no clear guidelines exist determining the most appropriate size tube. Imaging airway preoperatively could aid clinical judgement and reduce risk. Patients included adult critical care who had preoperative imaging. computed tomography scans chest radiographs were reviewed. Measurements taken scaled to known internal diameter an endotracheal A four-point scoring system was developed identify better suited non-standard Data from 23 analyzed using Statistical Package for Social Sciences™ (SPSS). Four measured points on imaging corresponded patients' size. Appropriate correlates with tracheal at tip (r2 = 0.135), carina 0.128), midpoint larynx 0.146), bronchial left mainstem 0.323), intrathoracic length 0.23). Among our cohort, score 4 predicts need larger Simple provides accurate measurement dimensions. Our method ensures selected according patient size, potentially reduces risks associated inappropriate sizing.
