Neodymium Magnet-Guided Removal of Metallic Soft Tissue Foreign Bodies in the Emergency Department
Efficacy and Safety of Neodymium Magnet-Guided Removal of Metallic Foreign Bodies in Soft Tissue in the Emergency Department
The goal of this clinical trial is to learn if a strong magnet (neodymium magnet) can help doctors remove metal objects stuck under the skin in adults. It will also learn about the safety of this method. The main questions it aims to answer are:
- How often can doctors remove the metal object with the help of the magnet?
- How long does the procedure take?
- How often do doctors need to make a cut in the skin, and how long is the cut?
- What problems do participants have within 15 days after the procedure?
- How satisfied are participants with the procedure?
Participants will:
- Have an X-ray to find the metal object
- Have the metal object removed with the help of the magnet in the emergency department, with or without numbing medicine (local anesthetic)
- Come back for a wound check 15 days after the procedure

Descripción detallada
This prospective, single-center, single-arm study is conducted in the Emergency Department of Bursa Uludag University Faculty of Medicine Hospital. Before the procedure, the location of the foreign body and its distance from the skin surface are measured on X-ray, and the entry site is photographed. Before sterile preparation, the magnetic property of the foreign body is confirmed with the neodymium magnet. After sterile preparation, the foreign body is localized with a sterile-draped neodymium magnet. Local anesthesia is applied if needed. The foreign body is removed through the existing wound or, if there is none, through a skin incision. The site is photographed again after removal. Prophylactic antibiotics are given for contaminated wounds. Participants are re-evaluated at suture removal or 15 days after the procedure.

Experimental: Neodymium Magnet-Guided Removal
Adults with a magnetic metallic foreign body in the soft tissue. The foreign body is removed with the help of a neodymium magnet in the emergency department, with or without local anesthesia. |
After sterile preparation, the foreign body is localized and pulled toward the skin surface with a sterile-draped neodymium (NdFeB) magnet, and removed through the existing wound or a skin incision.
