From the Guidelines
The recommended suture size for skin closure is 4-0, as it provides a balance between tensile strength and minimal tissue trauma, according to the most recent and highest quality study 1. When considering the size of the suture for skin closure, several factors come into play, including the anatomical location of the wound, the depth and tension of the wound, and the patient's healing characteristics.
- For most surgical sites, a 4-0 suture size is commonly used, as seen in studies comparing continuous versus interrupted sutures, where 4-0 poliglecaprone and 4-0 polyglactin were used for continuous subcuticular sutures 1.
- The choice of suture size is crucial, as it affects the wound's healing process and the risk of complications such as superficial wound dehiscence and surgical site infections (SSI).
- A 4-0 suture size is preferred because it retains approximately 50 to 75% of its original tensile strength after 1 week in situ, providing extra support for the wound and reducing the risk of superficial wound dehiscence 1.
- While other suture sizes, such as 3-0,5-0, or 6-0, may be used for specific wound locations or characteristics, the 4-0 suture size is generally considered the most appropriate for skin closure, as it balances tensile strength with minimal tissue trauma.
- It's worth noting that the use of triclosan-coated sutures, as mentioned in another study 1, may reduce SSI prevalence, but this does not directly impact the choice of suture size.
From the Research
Suture Size for Skin Closure
- The recommended suture size for skin closure is not explicitly stated in the provided studies 2, 3, 4, 5, 6.
- These studies focus on the treatment and management of keloids and hypertrophic scars, rather than the specifics of suture size for skin closure.
- The studies discuss various treatment options, including intralesional injections, laser therapies, and surgical revisions, but do not provide information on suture size.
- It is likely that the choice of suture size for skin closure depends on the specific surgical procedure, the location of the incision, and the patient's individual characteristics, but this information is not available in the provided studies.
