The suture in the tissue does not need to be removed, but the skin suture needs to be removed. The suture removal time depends on the suture site and surgical method. Generally, the head, face and neck wounds are removed in 4-5 days, the chest, abdomen, back and buttocks wounds are removed in 7-9 days, the perineum wounds are removed in 5-6 days, and the limbs wounds are removed in 10- 14 days to reduce the wound tension.

operation sequence/order

1 Uncover the dressing, expose the seam, and wipe off the tape traces with a gasoline or turpentine cotton swab.

2. Disinfect the suture and surrounding skin with 2% iodine, 70% alcohol or iodophor for 5 ~ 6 cm from the inside out, and air dry.

3. Check whether the incision has been firmly healed, and then remove the stitches after confirmation.

4. Gently lift the knotted thread on the suture mouth with toothless tweezers to expose the suture buried in the skin, cut the exposed part with thread scissors, gently pull it out, wipe it with alcohol cotton ball 1 time after thread removal, cover it with dressing, and then fix it with adhesive tape. If the wound healing is not reliable, stitches can be removed intermittently.

5. If the surface of the wound is cracked, you can disinfect the flame of the alcohol lamp with butterfly-shaped adhesive tape, and then close and fix the bandage on both sides.

6. Remove the stitches gently, and don't cut both ends at the same time to prevent the stitches from remaining under the skin.

Matters needing attention

1. When cutting the thread, the position should not be in the middle of the suture or on the opposite side of the knot. Otherwise, when the thread is pulled out, the suture exposed under the skin and contaminated by bacteria will be pulled under the skin, increasing the chance of infection.

2. It is best to cut the suture with scissors tip when removing the suture, so as to avoid the pain caused by excessive traction of the suture and local infection caused by moving the suture.

3. Observe the wound condition 1 ~ 2 days after taking out stitches to see if there is any wound dehiscence. If the wound does not heal well or split, you can use butterfly tape to protect the wound until it heals.

4. Delayed suture removal should be considered in the following situations: ① severe anemia, emaciation and cachexia; (2) Serious water loss or water-electrolyte metabolic disorder has not been corrected; (3) Old people and infants with poor wound healing; (4) Thoracic and abdominal wounds with respiratory tract infection and cough; ⑤ The local edema of incision is obvious and lasts for a long time.
