Deep wound stitches: what to know

A deep cut can affect skin, fat, muscle, tendons, nerves or blood vessels. A clinician first checks movement, sensation and circulation, then cleans the wound and removes visible debris. Local anaesthetic such as lidocaine can numb the area while the wound is repaired. Deep or absorbable sutures may support tissue beneath the skin; other stitches may close the surface and later need removal. Some wounds should not be closed immediately if they are heavily contaminated, infected or have damaged structures needing specialist care.

Follow the dressing and washing instructions given at the visit. Keep the wound protected, avoid picking at scabs or pulling the thread, and limit activity that stretches the area. Keep the limb raised when advised for swelling. Take prescribed medicine as directed and check before applying creams. Attend the planned review so stitches can be checked or removed at the appropriate time; removal timing varies with the wound’s site and depth.

Seek emergency help for bleeding that continues despite firm direct pressure, loss of movement or sensation, a cold or pale limb, or a wound caused by a major crush or bite. Contact a clinician promptly for spreading redness, increasing warmth or swelling, pus, worsening pain, fever, wound edges opening, or red streaks moving away from the wound. Ask about tetanus vaccination if the injury was dirty, deep or caused by a puncture.

Ask which layers were injured, whether absorbable stitches were used, how to dress and wash the wound, when review or removal is due, and whether tetanus protection is needed.
