Wound closure strip

Wound closure strip is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wound closure strip rather than just read about it. In short: Wound closure strips are porous surgical tape strips which can be used to close small wounds. They are applied across the laceration in a manner which pulls the skin on either side of the wound together.

Key takeaways

Wound closure strip belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wound closure strip to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wound closure strip from memory before moving on to harder problems.

Reference excerpt

Wound closure strips are porous surgical tape strips which can be used to close small wounds. They are applied across the laceration in a manner which pulls the skin on either side of the wound together. Wound closure strips may be used instead of sutures (stitches) in some injuries, because they lessen scarring and are easier to care for.

Names Wound closure strips are often referred to using the genericized trademark Steri-Strips, the brand name used by 3M's Nexcare. The precursor to the Steri-Strip was 3M's Micropore brand of microporous surgical tape.

Usage

Wound closure strips are ideal for use in highly contoured areas or areas of musculoskeletal movements, such as joints. They are also for use in areas where swelling, edema, hematomas, or bloating may occur. Additionally, they provide wound support following early suture or staple removal. Wound closure strips may also be applied together with special glue (e.g. 2-Octyl cyanoacrylate, also known as Dermabond) to secure the wound.

Benefits The porous fabric of Steri-Strips allows more fresh air to the wound and prevent skin maceration. Plastic or other non-porous bandages often prevent perspiration and other bodily fluids from drying and are more likely to cause the wound to be macerated, which increases risk of bacterial or fungal infection. Steri-strips result in less scarring when compared to staples or sutures. They present a lesser chance of infection than sutures or staples.

Variations Reinforced skin closures: These are sterile skin closure strips that are made of a porous, non-woven backing coated with a pressure-sensitive, hypoallergenic adhesive and reinforced with polyester filaments for added strength. They provide general wound support for increased tensile strength and finer wound edge approximation. Blend tone skin closures non-reinforced: These are sterile, light beige skin closure strips made of a porous, non-woven backing coated with a pressure sensitive, hypoallergenic adhesive. They blend with and allow the natural skin tone (of light beige people) to show through. They are for use in areas where a cosmetically pleasing appearance is desirable, such as the face or arms. Butterfly closure strips: Butterfly closures are a type of adhesive strip consisting of two connected adhesive pads. The pads are attached to either side of the wound to hold the wound closed. Like wound closure strips, butterfly closures do not require a medical professional to apply and can result in improved cosmetic outcomes for small wounds, compared to surgical sutures. Waterproof closure strips: Steri-Strips are paper-based, so durability and usage can be compromised if they get wet, requiring dryness and precision. But some variations are made of a synthetic material that will repel water and therefore remain in place longer. The alternative 'butterfly' version of the strips, with two broader pads, has also waterproof variants.

Alternatives Some forms of cyanoacrylate glue may also be used for similar purposes. There are three cyanoacrylate compounds currently available as topical skin adhesives. 2-Octyl cyanoacrylate is marketed as Dermabond, SurgiSeal, and more recently LiquiBand Exceed. n-Butyl cyanoacrylate is marketed as Histoacryl, Indermil, GluStitch, GluSeal, PeriAcryl, and LiquiBand. The compound ethyl 2-cyanoacrylate is available as Epiglu.

Worked examples

Example 1 — a first encounter with Wound closure strip

Start with the simplest possible case. Write down what Wound closure strip claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wound closure strip before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wound closure strip ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wound closure strip

In research: Wound closure strip appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wound closure strip in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wound closure strip is common in secondary-school and first-year university syllabi. It links to neighbouring topics Adhesive tape, First aid, Medical dressings, so understanding it makes those chapters shorter.
In everyday life: Look for Wound closure strip outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
