Wound Closure Strips: Sizes, Technique and When to Choose Them Over Sutures

A skin closure strip is the least invasive way to hold the edges of a small laceration together, and it is the easiest way to make a wound worse if it is used on the wrong one. The decision is about tension, depth and contamination, not about convenience.

What Strips Do Well

Adhesive strips approximate the skin edges of a superficial wound that is not under tension: small lacerations on the forehead, the scalpel nick from a minor procedure, a clean cut that has already stopped bleeding. A sterile 1/2 × 4 inch closure strip comes six to a pack and fifty packs to a box, which is a practical reserve for a clinic that closes a small wound every week or two. The strip holds the epidermis; it does not close a deep layer, and it does not replace a layered repair when muscle or fat is involved.

Sizing and Application

Prepare the skin first. Dry the surrounding skin and remove any ointment, because adhesive does not stick to a greasy surface, and a strip that lifts in the first hour has failed. Benzoin or a skin barrier preparation improves adhesion where the wound sits on a moving area, provided the wound itself is not contaminated with it. Place the first strip across the middle of the wound, perpendicular to the wound line, then add strips working outward with even spacing, pressing each end down onto dry skin rather than onto the wound edges. Pulling the two skin edges together by hand before laying the strip keeps the wound approximated instead of tented.

Strip width and length should span the wound with enough margin to stick: an inch of adhesion on either side is a working rule. A narrow strip on a wide wound peels at the edges, and an oversized strip on a small cut lifts the skin when the patient moves.

When Strips Are the Wrong Choice

Do not close a laceration with strips if it is gaping, deep, visibly contaminated, bleeding actively, over a joint that will be flexed, or on a patient whose wound is already showing signs of infection. Bites, puncture wounds and crush injuries are referred or managed differently because closing the surface can trap contamination underneath. Where closure is required and strips will not hold, the clinic uses sutures or adhesive glue and follows its own scope of practice, and closure tape versus sutures sets out the comparison in more detail.

Follow-Up and Stocking

Tell the patient to keep the strips dry for the first day, avoid soaking, and return if the wound opens, bleeds or becomes painful and hot. Public Health Ontario's infection prevention and control material covers the dressing and wound care routines around that follow-up.

Strips are usually left in place for several days and either fall off or are removed when the wound has sealed, and the timing is a clinical decision rather than a supply decision. Reinforce a strip that lifts at one corner with a fresh strip rather than taping over it.

Keep closure strips with the rest of the minor procedure shelf: cloth tape, transparent tape, dressings and hypoallergenic paper tape for patients who react to adhesives. A laceration repair supplies checklist and suture removal kit selection cover the rest of the set-up, and the learning hub indexes the wound care series.

Frequently Asked Questions

Which lacerations suit wound closure strips?

Small, superficial, clean wounds that are not under tension and have stopped bleeding. Strips hold the skin edges together while they heal; they do not close deep tissue.

How long should closure strips stay on?

Several days, until the wound has sealed, or until the strips fall off. The timing is a clinical decision. Keep the area dry for the first day and replace any strip that lifts at a corner.

How wide should each strip be?

Long enough to span the wound with about an inch of adhesion on each side. Strips that are too narrow peel at the edges, and oversized strips pull at the skin when the patient moves.

When should a clinic use sutures instead?

When the wound gapes, is deep or contaminated, bleeds actively, crosses a joint, or shows signs of infection. Bites and puncture wounds are managed differently because closing the skin can trap contamination.
