Skin Primary Closure (Suturing): A Complete Guide for Operating Room Nurses
Category: Basic Surgical Skills / Wound Closure
Reading Time: 10–12 minutes
What Is Primary Skin Closure?
Primary skin closure is the process of approximating the edges of a clean wound immediately after surgery or trauma using sutures, staples, adhesive strips, or tissue adhesives. Proper wound closure restores skin integrity, minimizes infection risk, reduces bleeding, and improves cosmetic outcomes.
For operating room nurses, understanding closure techniques and assisting surgeons efficiently are essential skills.
📌Quick Facts
| Item | Details |
|---|---|
| Procedure | Primary Skin Closure |
| Specialty | General Surgery / All Surgical Specialties |
| Anesthesia | Usually Local Anesthesia |
| Common Closure Methods | Simple Interrupted, Vertical Mattress, Horizontal Mattress, Subcuticular, Staples |
| Main Instruments | Needle Holder, Tissue Forceps, Scissors, Sutures |
Indications
Primary skin closure is indicated for:
- Clean surgical incisions
- Acute lacerations with healthy tissue
- Surgical wounds immediately after an operation
Contraindications
Primary closure should generally be avoided in:
- Heavily contaminated wounds
- Infected wounds
- Wounds with significant tissue necrosis
These situations may require delayed closure or secondary healing.
Preoperative Wound Preparation
Before skin closure, appropriate wound preparation is essential.
Hair Removal
Hair should only be removed when necessary. Routine shaving is discouraged because it may increase the risk of surgical site infection.
Irrigation
The wound should be irrigated thoroughly with sterile saline under pressure to remove debris and decrease bacterial contamination.
Wound Cleansing
Carefully remove foreign material while minimizing additional tissue injury.
Debridement
Devitalized tissue should be excised before closure to improve wound healing.
Patient Position
The patient should be positioned to allow the surgeon comfortable access to the wound while avoiding excessive tension on the operative site.
Instruments Required
- Needle Holder
- Tooth Forceps
- Surgical Scissors
- Sterile Gauze
- Appropriate Suture Material
🕒Surgical Techniques
1. Simple Interrupted Suture
The most commonly used skin closure technique.
Advantages
- Easy to perform
- Excellent wound edge approximation
- Individual stitches can be removed independently
- Strong wound security
Key Points
- Enter the skin at approximately 90 degrees.
- Take symmetrical bites on both sides.
- Evert the wound edges.
- Tie knots without excessive tension.


2. Vertical Mattress Suture
Vertical mattress sutures provide both deep and superficial closure.
Indications
- High-tension wounds
- Thick skin
- Areas requiring wound edge eversion
Advantages
- Excellent wound eversion
- Reduces dead space
- Strong wound support


3. Horizontal Mattress Suture
Used for wounds under moderate tension.
Advantages
- Distributes tension evenly
- Improves wound stability
- Useful for fragile skin
Avoid excessive tightening because it may compromise blood supply.

4. Subcuticular (Subcuticular) Suture
A continuous intradermal suture placed beneath the epidermis.
Indications
- Cosmetic closure
- Clean elective surgery
- Plastic surgery
- Pediatric surgery
Advantages
- Excellent cosmetic appearance
- No external suture marks
- Comfortable for patients

Staple Closure
Skin staples are commonly used for:
- Scalp
- Abdomen
- Extremities
Advantages
- Very fast
- Easy removal
- Suitable for long incisions
Disadvantages
- Poor cosmetic outcome compared with sutures
- Less precise skin approximation

Surgical Adhesive Strips
Adhesive strips can be used:
- After suture removal
- Together with sutures
- For superficial low-tension wounds
They provide additional support while minimizing skin trauma.

Tissue Adhesives
Cyanoacrylate tissue adhesive is suitable for:
- Small clean wounds
- Pediatric patients
- Low-tension wounds
Advantages
- No suture removal
- Quick application
- Excellent patient comfort
Avoid using tissue adhesive on wounds under significant tension.
Suture Removal
Proper suture removal is as important as proper placement.
General principles include:
- Cut the suture close to the skin.
- Pull the clean portion through the wound.
- Avoid dragging contaminated external suture material beneath the skin.
- Inspect wound integrity throughout removal.

⚠️Common Closure Errors
| Problem | Prevention |
|---|---|
| Wound inversion | Ensure proper wound edge eversion |
| Excessive tension | Tie knots gently |
| Unequal bites | Symmetrical needle placement |
| Tissue ischemia | Avoid overtightening |
| Poor cosmetic result | Select the appropriate closure technique |
💎OR Pearls
✔ Enter the skin at a 90° angle whenever possible.
✔ Always evert the wound edges.
✔ Never tie knots too tightly.
✔ Match the closure technique to wound tension.
✔ Keep the operative field clean before closure.
✅30-Second OR Checklist
✅ Wound irrigated
✅ Debridement completed
✅ Appropriate suture selected
✅ Needle count correct
✅ Wound edges everted
✅ Hemostasis confirmed
✅ Dressing applied
Frequently Asked Questions
Which skin closure technique is used most often?
Simple interrupted sutures remain the standard technique because they are reliable, easy to perform, and allow selective stitch removal.
When should a vertical mattress suture be used?
It is preferred for wounds under high tension or when wound edge eversion is important.
Why is a subcuticular suture popular?
Because it provides excellent cosmetic results with minimal visible scarring.
When are skin staples preferred?
Staples are ideal for long surgical incisions where rapid closure is required, such as abdominal or scalp procedures.
Conclusion
Primary skin closure is one of the most fundamental surgical skills. Whether using simple interrupted sutures, mattress sutures, subcuticular techniques, staples, or tissue adhesives, the goals remain the same: precise wound edge approximation, minimal tissue trauma, reduced infection risk, and optimal cosmetic healing.
Operating room nurses should understand each closure method, recognize its indications, prepare the appropriate instruments, and assist surgeons efficiently to ensure safe and effective wound closure.
