Surgical glue, also known as tissue adhesive, is a medical adhesive used to seal and bond tissues together after a wound or incision. It provides a protective, waterproof barrier over the wound, helping to hold the edges closed while the body naturally heals underneath. This method of wound closure is often favored for its rapid application, minimal discomfort, and aesthetic benefits, as it can lead to less noticeable scarring.
Typical Duration and Influencing Factors
Surgical glue typically remains on the skin for about 5 to 10 days, eventually forming a scab-like layer that peels or flakes off as the wound heals. In some cases, it can last up to two or three weeks, depending on various factors.
Several factors influence how long surgical glue lasts, including wound location. Areas with frequent movement, such as joints, or those prone to friction from clothing, may cause the glue to detach more quickly. Skin type and moisture levels also contribute, as oily or excessively moist skin can reduce the adhesive’s effectiveness.
The specific type of surgical glue used can impact its longevity, with different formulations designed for varying adhesive properties and flexibility. A patient’s activity level can affect the glue’s duration; high activity or excessive sweating may lead to premature detachment. As the wound progresses through its natural healing stages, the underlying skin strengthens, and the glue naturally loses its adherence and begins to come off.
Caring for Surgical Glue
Proper care of surgical glue helps ensure it functions as intended. Keeping the glued area dry is important, especially in the initial days after application. While brief showers are permissible after the first 24-48 hours, avoid prolonged soaking from baths, swimming, or hot tubs, as this can cause the glue to soften and detach prematurely. After showering, gently pat the area dry instead of rubbing.
Cleaning around the wound should be done gently with soap and water, avoiding scrubbing or aggressive cleaning directly on the glue. Avoid applying lotions, ointments, or petroleum-based products directly over the glue, as these substances can break down the adhesive and cause it to come off sooner. This includes antibiotic ointments, unless specifically instructed by a healthcare provider.
Protecting the glued site from friction and scratching is advisable. Avoiding tight clothing or anything that might rub against the area can help preserve the glue. Resist the urge to pick or peel at the glue, even if it starts to lift at the edges; allow it to come off naturally as the wound heals.
When Surgical Glue Detaches
Surgical glue will gradually peel or flake off on its own as the skin underneath heals. This detachment typically occurs in pieces rather than all at once. It is not necessary to intervene or try to remove the glue yourself, as doing so could disrupt the healing wound.
However, there are specific signs that warrant contacting a doctor. These include any indications of infection, such as increasing redness, warmth, swelling, significant pain, or the presence of pus or foul-smelling discharge around the wound. Medical attention is also needed if the wound reopens or gaps before the glue has fully detached and the wound has healed.
If the surgical glue detaches much sooner than expected and the wound edges are not staying together, or if you experience severe pain, it is important to seek medical advice. While rare, if the glue remains on the skin significantly longer than the typical timeframe (e.g., several weeks) and causes concern, consulting your surgeon is appropriate.
