What should you know about sterile stitches?

Sutures bring separated skin or deeper tissue into a position that supports healing. They may be dissolvable, or they may need removal by a healthcare professional. The thread can be smooth or textured and is selected according to the wound, its location, tension, and the tissue involved. Local anaesthetic such as lidocaine may be used to numb the area during repair.

Sterility reduces contamination during the procedure, but it does not make a wound immune to infection afterward. Mild tenderness, tightness, bruising, or a small amount of dried blood can occur as the site settles. The wound still needs protection from dirt, stretching, and unnecessary handling.

Keep the wound and surrounding dressing as directed by the treating team. Wash your hands before checking it, and do not pick at scabs or pull at thread ends. Avoid soaking the area until you have been told it is suitable; brief washing may be allowed depending on the wound and repair. Reduce activities that stretch the stitched skin, especially if the wound crosses a joint.

Attend the planned review or removal appointment. Tell the clinician if you take medicines that affect bleeding, have diabetes, or have reacted to suture materials before. If the injury was dirty or caused by an object that could carry tetanus, ask whether vaccination is needed.

Get prompt advice if redness spreads, pain worsens, swelling increases, pus appears, the skin becomes hot, or you develop fever. Seek urgent help for uncontrolled bleeding, a wound that opens, new numbness, reduced movement, or a pale or blue area beyond the repair. A stitch that loosens is worth reporting because the wound may need assessment.

Ask whether your stitches dissolve or require removal, how to clean the area, when you can return to normal activity, and what dressing is appropriate. Confirm the review date and ask how to protect the scar from friction and strong sunlight once the wound has closed.
