Surgical glue is a medical adhesive used to close skin wounds after surgical procedures. It holds the edges of an incision together without the need for traditional stitches or staples. This method secures the wound, allowing the body’s natural healing processes to begin. Surgical glue also serves as a protective barrier over the incision, which can simplify wound care for patients.
Understanding Surgical Glue
Surgical glues are specialized medical adhesives designed to hold skin edges together. One common type is cyanoacrylate-based adhesive, formulated for medical use, which polymerizes rapidly upon contact with skin moisture. Another type is fibrin-based sealant, mimicking the body’s natural blood clotting process. These glues form a flexible, waterproof film over the wound. This film acts as a protective barrier, keeping the wound closed and helping to prevent bacteria from entering.
The Healing Journey
Surgical glue sets within minutes, providing immediate incision closure. This allows the underlying tissue to begin its repair process. For superficial skin healing, the surgical glue typically starts to peel or fall off within 5 to 10 days, though it can take up to three weeks to completely detach. This natural shedding indicates that the superficial skin layers have sufficiently healed.
While the surface glue detaches, deeper tissue healing continues for a much longer period. Wounds gradually increase in strength over approximately six weeks following the injury. The remodeling phase of healing, where collagen strengthens tissue and scars mature, can last from 21 days up to two years. Therefore, while the visible glue is gone relatively quickly, full internal healing and scar maturation are ongoing for several months to a couple of years.
Variables Affecting Recovery
Several factors influence how quickly a surgical incision closed with glue heals. A patient’s overall health is important; younger individuals generally heal faster than older adults. Adequate nutrition, including protein and vitamin intake, also aids tissue repair. Chronic medical conditions, such as diabetes or immune system issues, can slow healing.
The incision’s characteristics also affect recovery time. Larger or deeper incisions, or those in high-movement areas like joints, may take longer to heal. A clean surgical cut typically heals more predictably than an irregular wound. External factors, such as infection, can significantly delay healing and require additional medical intervention.
Post-Surgical Care and Concerns
Proper care of a surgical incision closed with glue is important for optimal healing. Keep the wound clean and dry, especially for the first 24 to 48 hours after surgery. After this, gentle showering is permitted, but pat the area dry immediately, avoiding scrubbing or rubbing. Avoid soaking the wound in baths, hot tubs, or swimming pools until the glue has completely fallen off.
Do not pick, scratch, or rub the surgical glue, as this can cause premature detachment and potentially reopen the wound. Applying creams, ointments, or lotions over the glue is also not recommended, as these products can soften the adhesive and cause it to detach prematurely. Activity restrictions, such as avoiding strenuous movements or stretching that put tension on the wound, are often advised for several weeks to allow for deeper healing.
Monitor the incision site for any signs of complications. Symptoms indicating infection include increasing redness, swelling, warmth, or pain around the wound. The presence of pus, a foul odor, or fever requires immediate contact with a healthcare provider. If wound edges separate or the incision reopens, medical attention is necessary.
