Trick of the Trade: Deflate an Undeflatable Gastrostomy Tube
A 54-year-old female with a past medical history of throat cancer presents for gastrostomy tube (G-tube) replacement. The initial G-tube was placed 3 years ago. Most recently, the patient had the G-tube changed 7 months ago. She presents to the Emergency Department because the G-tube is leaking from the tubing that is external to the skin. When you attempt to deflate the cuff, you are unsuccessful.
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 necessary to ventilate the patient [2].
