When Does a Cut Need Stitches? A Wound Care Guide from a Physician

You’re bleeding. You’ve got a kitchen knife cut, a fall on concrete, a broken glass injury, or your child split their chin open on the coffee table. The first question: does this need stitches, or can I handle it at home?

I’m Dr. Lisa Clay, board-certified family physician and founder of Monarch Medicine Urgent Care in Carmel. I perform laceration repair on adults and children regularly. Here’s the assessment I want you to make while you’re holding pressure on that wound.

Your Cut Probably Needs Stitches If:

You Can Probably Manage at Home If:

The 6-Hour Rule

If a cut needs stitches, timing matters. The ideal window for primary wound closure is within 6–8 hours of the injury (up to 12–24 hours for facial wounds). After that, the risk of trapping bacteria under the closure increases, and your physician may choose to leave the wound open, clean it, and let it heal by secondary intention.

Don’t wait until tomorrow to see if it gets better. If you think it might need stitches, come in today.

What Happens During Laceration Repair

At Monarch Medicine, laceration repair follows a standard protocol:

1. Assessment — wound depth, length, location, mechanism of injury, tendon/nerve involvement
2. Anesthesia — local lidocaine injection to numb the area (the injection stings briefly, then you feel nothing)
3. Irrigation — thorough wound cleaning with saline to remove debris and reduce infection risk
4. Closure — sutures (stitches), staples, or wound adhesive (glue) depending on the wound
5. Tetanus assessment — booster given if yours isn’t current (every 10 years, or 5 years for dirty wounds)
6. Wound care instructions — how to care for the wound, when to return for suture removal, signs of infection to watch for

Sutures vs. Staples vs. Glue

• Sutures (stitches) — most common method. Best for deep wounds, facial lacerations, and wounds over joints. Removed in 5–14 days depending on location.
• Staples — faster application. Used for scalp lacerations and linear wounds on the trunk or extremities. Removed in 7–10 days.
• Wound adhesive (Dermabond) — no removal needed. Best for clean, shallow cuts, especially in children. Falls off on its own in 5–10 days.

Wound Care for Children

Kids get cuts constantly — playground falls, kitchen accidents, roughhousing with siblings. At Monarch Medicine, we use age-appropriate techniques to minimize pain and anxiety. For smaller cuts, wound glue is often the best choice for children — it’s painless to apply, doesn’t require removal, and the cosmetic result is excellent.

We see children of all ages. MinuteClinic and pharmacy clinics cannot do stitches at any age — they’ll refer you to the ER, where you’ll wait 2–4 hours and pay significantly more.

Signs of Wound Infection

Whether your wound was stitched or managed at home, watch for these signs in the days following the injury:

• Increasing redness spreading from the wound edges
• Warmth around the wound
• Swelling that’s getting worse, not better
• Pus or cloudy drainage
• Red streaks extending from the wound toward the heart
• Fever
• Increasing pain after the first 24–48 hours (pain should be improving, not worsening)

If you notice any of these, walk back in. Wound infections caught early are easily treated with antibiotics. Delayed treatment can lead to abscess formation or cellulitis.
