How effective is wound suturing for cuts and lacerations?

Sutures hold separated skin edges in a controlled position so the body can repair the tissue between them. They may help control bleeding, protect deeper structures and produce a neater healing line when used after appropriate cleaning. A clinician first checks the wound's depth, contamination, location, age and effect on movement or sensation. Some wounds are better managed with adhesive, strips, delayed closure or a dressing. Closing a contaminated, infected or bite wound without the right plan can trap harmful material inside.

Apply gentle pressure with clean gauze, rinse away surface dirt with clean running water and cover the wound while arranging assessment. Do not push an embedded object out or try to stitch the wound yourself. After suturing, keep the area clean and follow the instructions about bathing, dressing changes and activity. Protect the repair from stretching and attend the planned appointment for wound review or suture removal when advised. Tell the clinician about allergies, medicines that affect bleeding and your tetanus history.

Seek urgent assessment for persistent bleeding, a deep or gaping wound, exposed tissue, numbness, weakness, reduced movement or an injury over a joint. Get prompt help if stitches split, the wound edges separate, redness spreads, swelling increases, pus appears, fever develops or pain is worsening. A facial wound, hand wound, bite or heavily contaminated injury may need specialist planning even when it looks straightforward.

Ask whether sutures are suitable, how the wound was cleaned and when the closure should be reviewed. Ask how to protect the repair, which symptoms suggest infection and whether tetanus protection needs updating.
