Abstract:
Cicatricial tracheal stenoses are mainly related to iatrogenic injury as postintubation, posttracheotomy or postoperative. Advances in airway prosthetics have provided a variety of silicone stents and expandable metal stents as a therapeutic option for tracheal stenoses. Nowadays, dynamic tracheal stents are performed prevalently for the treatment of tracheal stenosis. Four major problems are currently associated with airway stents: Mucostasis, formation of granulation tissue, infection and migration. In this report, we present a case of swallowing a tracheal dynamic stent as an unusual complication of tracheal stents.

Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Oxygen Delivering System III: Tracheostomy and T-piece
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
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.
