Surgical glue, also known as tissue adhesive or liquid stitches, is a medical adhesive used to close wounds and incisions. It bonds tissues together, offering an alternative to traditional stitches or staples. This adhesive provides a strong, flexible, and waterproof barrier over the wound, aiding healing.
How Surgical Glue Works
Surgical glue typically relies on cyanoacrylate-based compounds. When this glue comes into contact with moisture on the skin or tissue, it rapidly polymerizes, forming a strong bond within seconds. This quick setting creates a protective, flexible layer over the wound, helping to hold the edges of the skin together.
Natural Detachment Process
The body naturally sheds surgical glue as the skin heals beneath it. This process occurs as the outer layers of the skin flake and peel away. Surgical glue is formulated to remain in place for a typical timeframe of 5 to 10 days, though some can last up to 2 or 3 weeks, depending on the location of the wound and the specific type of glue used. During this period, the glue will gradually wear off on its own, which is the safest and intended method of removal.
Professional Removal and Why Self-Removal is Discouraged
Medical professionals should remove surgical glue if necessary. They may use specialized medical-grade solvents, such as petroleum jelly or acetone, to gently loosen the adhesive, but only when medically indicated.
Attempting to remove surgical glue at home is strongly discouraged due to several risks. Picking, scratching, or scrubbing the glue can cause skin irritation, reopen the wound, or delay healing. Using household chemicals, alcohol, or non-medical solvents can lead to allergic reactions, chemical burns, or further damage to the healing skin. These actions can also compromise the wound’s protective barrier, increasing the risk of infection and scarring.
When to Seek Medical Advice
Contacting a medical professional is important if you experience specific issues with surgical glue. Signs of a potential infection include increased redness, swelling, warmth, pain, or pus draining from the wound. You should also seek advice if you notice a rash, hives, or severe itching, which could indicate an allergic reaction. If the wound reopens, bleeds, or if the glue has not come off naturally after the expected timeframe, professional medical assessment is advised.
