The requirement to remove jewelry before any surgical procedure is a mandatory safety protocol enforced across all healthcare facilities. This rule is based on distinct, verifiable risks that metal, stones, and other materials introduce into the operating room environment. The presence of jewelry, even small pieces, can directly interfere with medical equipment and compromise the patient’s well-being. Understanding these risks is fundamental to recognizing why this is a non-negotiable step in pre-operative preparation.
Preventing Electrical Burns
The primary concern regarding metal jewelry during surgery is the potential for severe thermal burns caused by electrosurgical units (ESUs). These devices, commonly known as electrocautery, are routinely used to cut tissue and seal blood vessels by passing a high-frequency electrical current through the patient’s body. A specialized return electrode pad, or grounding pad, is placed on the patient to safely draw the current out and complete the electrical circuit.
Metal jewelry acts as an unintended alternative pathway for this electrical current, especially if the return pad is compromised or the jewelry is near the surgical site. Because the surface area of jewelry is significantly smaller than the return pad, electrical energy concentrates at the contact point between the metal and the skin. This high concentration of energy generates intense heat, which can cause a burn at the jewelry site, sometimes resulting in deep tissue damage. A malfunction in the ESU system can turn any metal on the patient’s body into a point of injury, even if the jewelry is not near the surgical site.
Reducing Infection Risk and Maintaining Sterility
Jewelry poses a threat to maintaining the sterile field, the zone immediately surrounding the patient and surgical instruments. The complex surfaces of rings, watches, and earrings, including settings, clasps, and grooves, are difficult to thoroughly clean and sterilize. These areas become reservoirs for bacteria and other microorganisms, even after a surgical scrub.
Surgical safety bodies recommend removing all jewelry because it inherently harbors a higher bacterial load than bare skin. Leaving jewelry on makes the necessary antiseptic skin preparation around the surgical site less effective, increasing the risk of a surgical site infection. Furthermore, jewelry could potentially fall off or snag and tear a sterile drape or a surgeon’s glove. This instantly contaminates the sterile environment and exposes the patient to pathogens.
Avoiding Physical Injury and Logistical Issues
Beyond electrical and infection risks, jewelry presents mechanical dangers and logistical complications within the operating room. During a procedure, the patient is often repositioned, or drapes and equipment are moved. This creates a risk that jewelry could snag on gowns, monitoring wires, or surgical instruments. Snagging can result in physical trauma, such as a tear to the skin around a piercing site.
Post-operative swelling is a common response to surgery and intravenous fluid administration, making rings and bracelets a particular concern. If a ring is left on and swelling occurs, the constriction can impede blood flow, potentially leading to tissue damage and requiring the ring to be cut off. Logistically, metal jewelry interferes with pre-operative and post-operative imaging, such as X-rays, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). The metal creates artifacts, or bright white distortions, on the images that can obscure underlying anatomy and make accurate diagnosis difficult or impossible. Finally, the busy environment of the operating room creates a risk for loss or damage of valuable items, which is prevented by removing all jewelry beforehand.
