Trick of the Trade: Nasal foreign body removal using foley catheter

    A healthy 4 year-old boy is brought in by mom for a plastic bead up his nose. The mom states, “The last time the other doctors had to be called, and it took forever. Oh, and I have to pick up his brother from school in 30 minutes.

Alternatively, the video above by Dr. Mellick demonstrates how a Katz Extractor can be used (start at 00:34 if you want to skip the introduction). This commercial device is based on the same idea, but it is more rigid, allowing for a single-handed technique. The catheter-based approach is often a favorite of emergency physicians over positive or negative pressure, glue, or forceps, because anecdotally it is better tolerated by patients and parents. However, the limited available literature is not able to support one technique over another. Pitfalls: Visualization: This technique still requires visualization. Do not insert the catheter blindly as the foreign body may dislodge posteriorly. If it does, immediately check the oropharynx. Although not reported, this may be a technique theoretically to avoid in very posterior foreign bodies … Continue reading Trick of the Trade: Nasal foreign body removal using foley catheter
