Suture and staple removal: a nursing guide

Suture and staple removal is a core nursing clinical skill performed once a wound has healed sufficiently to hold its edges without mechanical support. Nursing students encounter this procedure in surgical, medical-surgical, and outpatient settings. Getting it right requires more than following a sequence of steps–it demands sound wound assessment, knowledge of removal timing by anatomical site, and the judgment to stop and escalate when healing is inadequate. This guide covers interrupted, continuous, mattress, and subcuticular suture removal as well as surgical staple removal, with timing tables, step-by-step rationale, and NCLEX-focused content to build both competence and test-readiness.

Quick-reference overview

Before diving into technique, orient yourself with this overview. A provider order is required before removal in most facilities.

Wound assessment before removal

Never remove sutures or staples from a wound that is not ready. The assessment happens before you open a suture removal kit.

Signs that healing is adequate:

• Wound edges are well approximated (touching, not gaping)
• No erythema extending beyond the immediate wound margin
• No warmth, induration, or fluctuance along the wound edges
• No purulent or malodorous drainage
• Granulation tissue visible at wound base (in open wounds being observed)
• Patient reports diminishing (not increasing) pain at the site

Signs that removal should be delayed or escalated:

• Wound edges separating or undermined
• Active infection: erythema spreading, warmth, purulent exudate, fever
• Wound less than minimum healing time for the anatomical site
• Patient on high-dose corticosteroids, immunosuppressants, or with uncontrolled diabetes–healing is delayed and sutures may need to stay longer
• Wound edges fragile or macerated from moisture

Document your pre-removal wound assessment in the patient’s chart, including wound dimensions, approximation status, drainage character, and periwound skin condition. If the wound is not ready, hold the procedure and notify the provider.

Equipment setup

Gather supplies before approaching the patient. In most facilities, removal is performed using sterile or clean technique depending on facility policy–confirm before starting.

Supplies:

• Suture removal kit (iris scissors or suture scissors + tissue forceps) or staple remover device
• Sterile gauze pads (4×4)
• Clean or sterile gloves (per facility policy)
• Antiseptic solution or normal saline for wound cleaning
• Steri-Strips and skin closure reinforcement tape (if needed post-removal)
• Waterproof trash bag
• Adequate lighting

Suture removal procedure

Interrupted sutures

Interrupted sutures are the most common type you will encounter in clinical practice and the most frequently tested on NCLEX. Each suture is tied and cut individually, so removing one does not compromise the others.

Continuous/running sutures

A continuous suture is a single strand that runs the full length of the wound in an uninterrupted pattern. The key risk: pulling the entire strand through as one piece drags external (contaminated) suture material through the suture track.

Technique:

1. Identify the knot at one end of the wound.
2. Cut the suture at the knot and at the loop just distal to it–this creates the first removable segment.
3. Pull the segment out and set it aside.
4. Continue cutting each exposed loop on the external surface and pulling the segment beneath out, working your way from one end of the wound to the other.
5. Never grasp the full length of suture and attempt to pull it free in one motion–this drags contaminated external material through tissue.

Mattress sutures

Mattress sutures provide tension reduction and are commonly placed in high-stress areas such as orthopaedic incisions, abdominal closures, and wounds under mechanical load.

Horizontal mattress sutures: The suture passes through the skin twice, parallel to the wound, forming a horizontal bridge on each side. Cut the exposed portion on one side close to the skin, then pull the entire suture out from the opposite side. Take care not to drag the external segment through tissue.

Vertical mattress sutures: The suture has both a deep bite and a superficial bite. Cut at the skin surface on both the superficial and deep portions, then remove each segment individually. Wound edges may appear slightly inverted–this is expected. Assess edges carefully after removal, as the deep bite means sutures have been providing more structural support than interrupted sutures.

Subcuticular/intradermal sutures

Subcuticular sutures run beneath the epidermis parallel to the wound surface. They are often used on the face and areas where cosmesis matters.

1. Locate the exposed tail or anchoring knot at one end of the wound.
2. Grasp the tail with forceps.
3. Press a folded piece of gauze firmly against the skin on either side of where the suture exits–this stabilizes tissue and prevents the suture from breaking during traction.
4. Pull the suture out in a slow, steady motion parallel to the skin surface. Avoid pulling perpendicular to the skin (upward) as this increases the risk of breaking the strand.
5. If resistance is felt, gently advance toward the wound a few millimeters and try again. Some serous attachment forms along the suture track after several days.

If the suture is absorbable, confirm with the provider whether removal is still indicated–many absorbable subcuticular sutures are left to dissolve.

Surgical staple removal procedure

Surgical staples are metal clips inserted with a stapling device. They are removed with a dedicated staple remover–a hinged instrument with a lower jaw that slides under the staple bridge and, when the handles are compressed, bends the staple into a W shape that lifts its legs free from the tissue.

Step-by-step:

1. Verify the provider order. Confirm the wound meets assessment criteria for removal.
2. Perform hand hygiene; don gloves.
3. Clean the staple line with saline or antiseptic.
4. Position the staple remover so the lower jaw is fully under the center of the first staple’s bridge–the curved lower arm must be completely beneath the staple before compressing.
5. Squeeze the handles fully and smoothly in one motion until both arms are together. This bends the staple into a W configuration and raises both prongs simultaneously from the tissue.
6. Lift the remover straight up and away from the wound–do not tilt or rock the device, which can tear tissue.
7. Place the removed staple on gauze.
8. In high-tension areas (abdominal closures, joint incisions), remove every other staple first. Assess wound integrity. Remove remaining staples if edges hold well, apply Steri-Strips over the remaining staples’ former sites.
9. Clean the staple line; apply Steri-Strips across the wound if additional support is needed.
10. Document the number of staples removed and wound appearance.

For context on post-surgical care that accompanies staple removal, see our guides on JP drain nursing care and Hemovac drain nursing.

Wound assessment after removal

Once sutures or staples are out, reassess the wound immediately and again before the patient leaves.

Reassessment checklist:

• Wound edges remain approximated after closure material is removed
• No bleeding from suture tracks (minor ooze is expected; active bleeding is not)
• No visible gap or separation along the wound line
• Periwound skin is intact, not macerated or fragile
• Patient reports no sudden pain increase

Steri-Strip application: Apply Steri-Strips when wound edges need reinforcement after removal, particularly in wounds that are borderline on timing, under tension, or in patients with healing risk factors. Place strips perpendicular to the wound, bridging both edges with slight but deliberate tension. Do not stretch the strip so tightly that it creates skin blistering. Instruct the patient to allow Steri-Strips to fall off naturally–typically within 7–10 days–rather than pulling them off, which can reopen the wound.

When to stop and call the provider:

• Wound dehiscence (edges separating) after staple or suture removal: do not continue. Cover with a moist sterile dressing, keep the patient calm and still, and notify the provider immediately.
• Wound evisceration (abdominal wound with organ protrusion): this is a surgical emergency. Cover exposed organs with a sterile saline-moistened dressing, do not attempt to push organs back, place patient in low Fowler’s position with knees flexed, call the provider emergently and activate emergency response per facility protocol.
• Signs of active infection discovered after removal: purulent drainage, significant erythema, warmth, patient febrile–notify provider and document.

For comprehensive infection prevention principles applicable to wound care, see our guide on infection control and isolation precautions.

Timing guidelines by wound location

Suture and staple removal timing depends on the anatomical location because vascularity, skin thickness, and mechanical stress differ across the body. The face heals faster due to excellent blood supply; areas over joints or under high tension heal more slowly.

These timing windows are guides, not rigid rules. Wound appearance at the time of scheduled removal always takes precedence over the calendar.

Patient education

Patients are discharged with sutures or staples still in place more often than many students expect–particularly after outpatient procedures or early surgical discharge. Teaching them what to look for and how to care for the wound at home is part of the nursing role.

What to expect after removal:

• The wound may feel slightly tender for 24–48 hours after removal.
• Minor ooze from suture tracks is normal for a few hours.
• A faint scar line is normal and will continue to fade over months.
• Steri-Strips, if applied, should be left in place until they fall off on their own–usually within 7–10 days.

Activity restrictions:

• Avoid soaking the wound (bath, pool, hot tub) for at least 24–48 hours after removal; showering is generally permitted with gentle water flow.
• Avoid activities that stretch or stress the wound site for the first week after removal–heavy lifting, vigorous exercise, or positions that maximally flex a joint over a healing incision.
• Sun protection: new scar tissue is highly susceptible to UV damage, which causes hyperpigmentation. Apply sunscreen (SPF 30+) to the scar once the wound is fully closed, or keep covered, for 6–12 months.

When to seek care:

• Wound edges separate or a visible gap appears.
• Increasing redness, warmth, or swelling at the site (not immediately after the procedure–this should decrease, not increase, with time).
• Purulent or foul-smelling drainage.
• Fever above 101°F (38.3°C).
• Severe or worsening pain.

NCLEX high-yield: 20 tips for suture and staple removal

1. A provider order is required before suture or staple removal in most facilities–never remove without one.
2. The cardinal rule of interrupted suture removal: cut the short arm below the knot, on the side of the wound, as close to the skin as possible.
3. Why cut below the knot? Cutting the short arm prevents dragging the contaminated external portion of the suture through subcutaneous tissue.
4. After cutting, pull the suture away from the wound (not across it) to minimize shear stress on healing tissue.
5. Never remove sutures from an infected wound without a specific provider order to do so–infection disrupts healing and the wound may not hold its edges.
6. Wound dehiscence after removal: cover with sterile moist dressing, keep patient still, notify provider immediately.
7. Wound evisceration (organ protrusion): sterile saline-moistened dressing over organs, do not push back, low Fowler’s with knees flexed, emergent provider notification.
8. The staple remover must be fully positioned under the staple bridge before compressing handles–a partial insertion bends only one prong and tears tissue.
9. Compressing the staple remover handles fully creates a W shape that simultaneously raises both prongs from the tissue.
10. Face and scalp sutures come out earliest (3–5 days for facial wounds) because facial vascularity supports rapid healing.
11. Joint sutures stay in the longest (14 days minimum) because mechanical stress from movement delays wound tensile strength.
12. Patients with diabetes, corticosteroid use, or malnutrition may need sutures left in place longer than the standard timing window.
13. Alternate-staple removal (every other staple, then reassess) reduces dehiscence risk in high-tension incisions.
14. Steri-Strips are applied perpendicular to the wound, bridging both edges with slight tension; they should fall off naturally.
15. Subcuticular suture removal: pull parallel to the skin surface, not perpendicular–pulling upward breaks the strand.
16. For continuous sutures, cut at each loop individually rather than pulling the full suture through; prevents dragging contaminated material through the suture track.
17. Mattress sutures are placed over high-tension wounds; horizontal and vertical types differ in how they distribute tension at the wound edges.
18. Do not soak the wound for at least 24–48 hours after removal–water immersion can soften healing tissue and reopen the wound.
19. Scar tissue is highly UV-sensitive; new scars should be protected with sunscreen or covering for 6–12 months to prevent hyperpigmentation.
20. If a wound is not ready for removal (infected, poorly approximated, ahead of minimum timing), hold the procedure and notify the provider–do not proceed based on the calendar alone.

Mastering suture and staple removal reinforces a broader clinical picture: every wound has a healing trajectory shaped by patient physiology, wound location, and the type of closure used. Assessing that trajectory–not just following a protocol–is what makes the difference between a safe removal and a dehiscence avoidable with one more day’s patience.
