Removing Simple Interrupted Sutures: A Step-by-Step Guide

Steri-strips are adhesive strips used to approximate wound edges after staples or sutures are removed, applied using clean technique rather than sterile technique; the procedure involves selecting appropriately sized strips, cleaning the wound edges, optionally applying benzoin tincture to improve adhesion, and placing strips across the wound from one end to the other while pulling edges together, with strips falling off naturally during healing and patients instructed not to pull them off as this could disrupt granulation tissue.

Effective post-surgical wound care involves proper dressing application and patient education. Steri-strips provide mechanical support and come off naturally when healing is complete. Tincture of benzoin secures strips but must avoid wound contact to prevent stinging. Non-stick dressings protect healing tissue. Patients must keep wounds dry and avoid ointments that may obscure healing progress. Scar cream applies only after complete healing. Clear instructions ensure proper recovery and prevent complications.

Wound closure strips (steri-strips) are adhesive strips used to hold together the edges of minor cuts, working like sutures but applied topically; they are best suited for fresh, minor wounds with straight edges and low contamination risk, and should not be used on facial wounds due to scarring risks. The proper application process includes irrigating the wound to remove debris, applying direct pressure with non-stick gauze to stop bleeding, ensuring the skin around the wound is dry, cutting the strips in half for better coverage, applying them approximately every eighth inch starting from the center, and covering with a non-stick dressing secured by medical tape. Patients should monitor for infection signs such as purulent drainage, redness, swelling, worsening pain, or bad odor, and seek medical attention if symptoms persist beyond three days or if the wound is deep, contaminated, won't stop bleeding, or is more than four hours old.

Steri-strips (white or brown tapes) bring the skin around the wound together and should be kept dry as moisture reduces their ability to stick. When tapes curl or peel away after 5 to 7 days, they can be gently wetted and removed. For daily washing, use liquid soap but avoid rubbing or actively washing the wound area for the first weeks; instead, rinse gently with warm water and pat dry before drying the rest of the body. Avoid creams, talcs, or ointments on the wound for the first months.

Steri-strips are applied after staple removal to help prevent wound dehiscence (wound opening) and maintain wound integrity. They serve as a protective measure against complications that can occur when staples or sutures are removed. The strips provide support to the healing incision and reduce the risk of the wound reopening during the healing process.

Proper suture management is critical to prevent complications like suture granulomas. Surgeons should count and verify all sutures placed during procedures, as dark hair can make it difficult to distinguish between hair and suture material. Running stitches require knots on both sides of the wound; removing only one knot and cutting the other strand can leave embedded material. Complete removal of all suture material, including knots and loops, is essential to prevent continued inflammation. When sutures are removed by others, the risk of missing material increases. Systematic verification and complete removal prevent foreign body reactions, sinus track formation, and recurrent inflammation.

Wound dehiscence occurs when a surgical wound opens completely or partially, or when there is discharge of serous fluid or pus. If there are no signs of infection and the wound simply opened with redness, it may be possible to resuture, but this requires evaluation by the operating surgeon to determine if the wound edges can be brought together and closed properly.

This video demonstrates the proper technique for removing simple interrupted surgical sutures, emphasizing key safety practices including verifying physician orders, obtaining patient consent, assessing the wound for infection before removal, using sterile gloves and antiseptic to prevent infection, removing every other suture first to prevent wound dehiscence, cutting the suture thread on the side of the knot closest to the skin to avoid introducing germs, and applying steri-strips to reinforce the wound closure.

Wound dehiscence is separation of sutured tissues, classified as superficial (skin/subcutaneous) or deep (muscle/aponeurosis). Primary cause is surgical site infection; other factors include technical errors, hematoma, increased intra-abdominal pressure, obesity, corticosteroids, malnutrition, and chronic diseases. Evisceration is protrusion of viscera through the incision, representing the most severe form. Management ranges from conservative observation for small defects to surgical revision for large dehiscences or evisceration.

When sutures become embedded in tissue, surgical removal is necessary to prevent complications. The procedure involves making a small incision to access and extract the embedded material. This is typically performed as an outpatient (ambulatory) surgery, meaning the patient does not need to be admitted to the hospital overnight. The incision is small and heals relatively quickly, though patients may need to take a few days off from normal activities.

This comprehensive protocol covers the complete process of removing wound closure devices. The core principle is the 'every other' removal technique, which involves removing alternating sutures or staples first to prevent wound dehiscence if healing is incomplete. The procedure includes: (1) Cleaning the wound area with normal saline and gauze, avoiding alcohol due to stinging; (2) Using proper tools—scissors with divots for sutures and specialized staple removers; (3) Removing devices by grabbing knots or prongs, never pulling through tissue; (4) Applying steri-strips to maintain wound closure during healing. The protocol emphasizes patient comfort, infection prevention, and proper wound assessment throughout the removal process.

To properly remove surgical staples from a healed laceration, use a staple remover with the two-toothed side positioned underneath the staple; gently squeeze to fold the staple backward and pull upward, avoiding downward pressure that could reopen the wound or cause bleeding; clean the area with an alcohol swab before removal and stop immediately if the wound opens during the procedure.

This comprehensive procedure covers the entire process of staple or suture removal. Pre-procedure steps include confirming the order, identifying the patient, explaining the procedure, assessing pain levels, and gathering necessary supplies (stapler remover kit, gauze, skin barrier, stair strips, normal saline, gloves, drape). Perform hand hygiene and set up a clean work area. Remove any dressings using the pull-and-hold skin method. Assess the wound for drainage, odor, skin approximation, swelling, redness, and temperature. Clean the wound using aseptic technique from center outward with new gauze for each wipe. Dry the wound from center to outside. Remove staples by positioning the remover under each staple and pressing down, removing every other staple systematically. Apply skin barrier around the incision and steri-strips to keep edges approximated. Document the procedure, count and discard staples, and reassess pain levels. Apply surgical gauze and tape it in place.

This video demonstrates proper techniques for removing surgical staples and sutures, including the method of removing alternate items first while keeping the wound well approximated, using sterile gauze as a barrier during staple removal, and applying ster strips afterward to maintain wound approximation and provide tensile strength without requiring a physician's order.

Surgical staples are small metal devices used to close wounds during surgery, and their removal is a nearly painless procedure that does not require sedation or local anesthetic; the surgeon uses a specialized staple remover tool that bends the staple's edges upward and extracts it quickly from the skin, leaving minimal discomfort and typically only a small amount of bleeding that stops quickly.

Scar maturation involves progressive collagen organization and vascularization over months to years. Myofibroblasts mediate wound contraction and matrix deposition. Growth factors coordinate the remodeling process. Scar tissue provides mechanical strength but lacks functional properties of original tissue. Hypertrophic scars remain confined to wound boundaries, while keloids extend beyond original margins.

The remodeling phase begins 1-2 weeks post-injury and lasts up to one year, with overlapping periods. Collagen reorganizes parallel to skin tension lines, with vitamin C facilitating cross-linking. Scar tissue never regains full tensile strength (reaching only 80% of uninjured tissue). Keloids extend beyond wound boundaries with 20x normal collagen and random orientation, affecting African Americans and Hispanics. Hypertrophic scars remain within boundaries with organized type III collagen. Understanding these distinctions guides appropriate treatment selection.

Hypertrophic scars progress through immature (red, vascular, firm) and mature (pale, flat, pliable) stages. Keloids extend beyond wound boundaries, occurring in 6-16% of African populations, and rarely resolve spontaneously. Comprehensive assessment includes objective methods (Cutometer for elasticity, Tensiometer for firmness, Chromameter for color, Doppler ultrasound for vascularity, ultrasound for thickness) and subjective methods (Vancouver Scar Scale with 13 parameters, Patient-Observer Scale, Visual Analog Scale). Surface area and volume are measured using digital calipers or tracing paper.

Scar formation involves fibroblast proliferation, matrix production, and collagen remodeling. Fibroblasts produce collagen, fibronectin, and other matrix components. During maturation, collagen synthesis and degradation reach equilibrium. Abnormal scarring (hypertrophic scars, keloids) results from dysregulated fibroblast activity and excessive collagen production. Hypertrophic scars remain within wound boundaries and may regress; keloids extend beyond boundaries and are more likely to recur. Scar maturation involves continuous collagen remodeling through enzyme action. The balance between collagen synthesis and degradation determines final scar strength. Macrophages play a crucial role in scar maturation by releasing enzymes that remodel the matrix and producing growth factors that regulate fibroblast activity.

This section addresses the two main types of problematic scars. Hypertrophic scars appear thickened and red within three months, typically flattening over one to two years without expanding beyond wound margins. Treatment options include intralesional steroid injections to reduce collagen production, laser treatments for redness reduction, and scar massage combined with silicone application. Pressure therapy may help but requires uncomfortable pressures (>34mmHg) for extended periods, making compliance difficult. Keloids extend beyond wound margins in a claw-like fashion, behaving like non-cancerous tumors with fibroblasts continuously producing collagen. Unlike hypertrophic scars, keloids grow during the remodeling phase (6-18 months) and often recur after treatment cessation. Management includes intralesional steroids, chemotherapy injections, radiation therapy (with excision), and magnetic pressure earrings for ear piercing keloid history. The overarching principle remains: tension minimization is key, and individualized surgeon consultation is essential for optimal outcomes.
