Abstract:
This report describes a case of sudden ventilatory failure, originally diagnosed as bronchospasm, in a child during general anesthesia. A blood clot impaction in the nasotracheal tube was detected using flexible fiberoptic bronchoscopy. The clot was successfully treated as a result of its passage. We hope this report will stress to dental anesthesiologists the intraoperative importance of fiberoptic bronchoscopy not only as an intubation-aiding device but also as a diagnostic and therapeutic tool.

The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...
Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
