Trick of the Trade: Tracheostomy leak temporization

By |Categories: ENT, Tricks of the Trade|

Patients who are tracheostomy and ventilator dependent are at increased risk for complications the longer they remain in this condition. One common complication is tracheomalacia. Progressive tracheomalacia can lead to air leaks around the tracheostomy cannula balloon. Initially, this can be managed by placing a longer tracheostomy cannula deeper into the trachea, however, these are often unavailable in the emergency department [1]. A second line strategy is to temporarily over-inflate the balloon, however, with chronic overinflation, eventually both the trachea and the neck stoma become too large, leading to an inability to maintain appropriate positive pressure (PEEP) and tidal volume [+]

He is afebrile, and mildly tachycardic, but his lung exam is fairly benign and he’s breathing easily without retractions. You can clearly see he has congestion. You instruct the parents to use saline irrigation and then nasal suctioning to clear the congestion as needed, and they say, “How can we do this if our child struggles? Won’t we just end up with a wet, angry, and congested child?” [+]

By |Categories: EMRad, Orthopedic, Radiology, Trauma|

Enter the “Can’t Miss” series: a series organized by body part that will help identify common and catastrophic injuries.
