Surgical Adhesives: Types, Benefits, Risks & Uses

Surgical adhesives are medical glues (synthetic polymers like polyethylene glycol or polyurethane) used to close wounds, repair tissues, and secure devices—often replacing sutures or staples.

Benefits

• Fast, suture-free closure
• Less scarring
• Minimally invasive
• Versatile across procedures
• Can reduce bleeding and provide infection barrier

Common Types

• Hydrogel-based: Water-based gel; gentle, for small wounds.
• Fibrin-based: Blood-derived protein; stronger, for larger wounds; costlier.
• Cyanoacrylate-based: Synthetic; bonds tissue to metal/plastic; very strong but can irritate skin.
• Sutures: Not adhesives, but often used with them; synthetic or natural (nylon, silk).

Forms & Selection

Liquids, gels, films—chosen based on procedure and tissue type.

Risks

• Skin irritation, allergic reactions
• Infection if contaminated
• Bleeding if near vessels

Discuss adhesive vs. suture options with your surgeon.
