From the Guidelines
Sutures from upper extremities should be removed between 10 to 14 days after the surgical intervention. This recommendation is based on the most recent evidence available, which suggests that sutures can be safely removed within this timeframe to promote optimal wound healing and minimize the risk of complications 1. The specific location and nature of the wound should be taken into account when determining the exact timing of suture removal. For example:
- Hand and finger sutures may require removal after 7-10 days
- Forearm and upper arm sutures can remain for 10-14 days
- Wounds over joints may need sutures removed earlier (7-10 days) to prevent restriction of movement
Before removal, it is essential to ensure that the wound edges appear well-approximated with minimal redness or drainage. The removal process should be performed using sterile technique with clean forceps and suture scissors. After removal, applying adhesive strips (like Steri-Strips) can provide additional support during the final healing phase. These strips can remain in place for 3-5 days and will often fall off naturally. It is crucial to watch for signs of infection, including increasing pain, redness, swelling, warmth, or drainage, which would warrant medical attention. The timing for suture removal balances the need for adequate wound healing against the risk of suture marks or tissue reaction from leaving them in too long. Although another study suggests removal within 7-10 days 1, the most recent and highest quality study recommends removal between 10 to 14 days 1.
From the Research
Optimal Time for Suture Removal
The optimal time for suture removal from the upper extremities depends on various factors, including the location of the wound, co-morbidity, and signs of early wound complications 2.
Factors Influencing Suture Removal Time
- Location of the wound: The timing of suture removal varies depending on the anatomical location of the wound 2.
- Co-morbidity: Patients with co-morbidities may require longer or shorter suture removal times depending on their individual condition 2.
- Signs of early wound complications: Wounds showing signs of infection or dehiscence may require earlier or delayed suture removal 3.
Recommended Suture Removal Times
- A study on rabbits found that removing sutures after 5 days resulted in the best wound healing outcomes compared to removal after 3 or 7 days 4.
- However, the recommended time for suture removal in humans is not explicitly stated in the provided studies, but it is generally agreed that sutures should be removed once the wound has sufficiently healed 3.
- The timing of suture removal can range from 3-14 days, depending on the location and type of wound 2.
Suture Removal Procedure
- Before removing sutures, the wound should be checked for signs of infection and indications of dehiscence 3.
- Removing sutures at the recommended time can help prevent new skin growth from covering the sutures and reduce scarring 3.
- An aseptic non-touch technique (ANTT) is recommended for suture removal, but local policy should always be followed 3.
