Surgical glue, also known as tissue adhesive, is a common method for closing wounds after surgical procedures or injuries. This medical adhesive holds skin edges together, creating a protective barrier that supports healing. It offers an alternative or complement to traditional sutures or staples, often chosen for its ease of application and ability to seal wounds. Surgical glue is designed to gradually detach as the wound heals underneath.
The Natural Shedding Process
Surgical glue forms a strong, flexible film over the wound, which then peels off as the skin regenerates. This natural shedding process usually occurs within 5 to 14 days following application. The glue gradually loosens and flakes away, often beginning at the edges of the treated area. As the outermost skin layer exfoliates, the adhesive naturally detaches. It is important to allow the glue to fall off independently and to avoid picking or peeling it, as premature removal can disrupt the healing wound.
Factors Influencing Shedding Time
Several factors influence how quickly surgical glue detaches from the skin. The wound’s location plays a role; glue on areas with more movement or friction, like joints, may come off sooner. Wound size and depth also impact retention, with larger or deeper wounds sometimes retaining glue longer.
Different glue formulations affect adhesion strength and duration; cyanoacrylate-based glues often last 5 to 10 days, while others dissolve faster. An individual’s skin healing rate also contributes. Post-operative care practices, such as maintaining dryness, also influence how long the adhesive stays on.
Care and Precautions
Proper care of the surgical site is important while the glue is present to ensure healing and prevent its premature removal. Keeping the area dry is recommended, as prolonged water exposure, soaking, or scrubbing can cause the glue to soften and detach too early. Brief showers are permissible, but the glued area should be gently patted dry afterward.
It is important to avoid picking, scratching, or rubbing the glue, allowing it to fall off naturally. Protecting the wound from friction, such as from tight clothing, also helps maintain the glue’s integrity. Lotions, creams, or ointments should not be applied over the glue, as these products can degrade the adhesive and lead to early detachment.
When to Seek Medical Advice
While surgical glue is safe, there are specific situations that warrant contacting a healthcare provider. Signs of a potential infection include increasing redness, swelling, warmth, worsening pain, or the presence of pus or foul-smelling discharge from the wound site. If the wound edges separate before the glue has come off, seek medical attention, as this indicates improper wound closure. Persistent or excessive itching or irritation caused by the glue also warrants consulting a doctor. If the surgical glue has not detached after the expected timeframe and there is concern, a healthcare provider can offer guidance.
