Abstract :
Prolonged mechanical ventilation via tracheostomy is a recognised cause of acquired subglottic and tracheal
stenosis. Anaesthetic management for endoscopic tracheal dilation in such patients is challenging, particularly when coexisting tracheomalacia raises concern for dynamic airway collapse with neuromuscular blockade, and when concurrent
laser use mandates a low fraction of inspired oxygen (FiO2). We report the case of a 23-year-old male who developed CottonMyer grade III subglottic/tracheal stenosis after four months of tracheostomy-assisted ventilation following exploratory
laparotomy for blunt abdominal trauma. He underwent tracheal dilation using a muscle-relaxant-free, spontaneousventilation technique with a dexmedetomidine infusion (loading dose 1 mcg/kg over 10 minutes, maintenance 0.3
mcg/kg/hour), high-dose fentanyl, and a supraglottic airway device (i-gel), at low FiO2 to accommodate simultaneous laser
use. This approach preserved spontaneous respiration, avoided airway collapse, minimised operating room pollution, and
maintained an adequate depth of anaesthesia throughout the procedure.
