Sutures for Wound Closure
Wound closure is the most fundamental application of surgical sutures, spanning emergency lacerations, elective incisions, and traumatic injuries. Selecting the correct suture material and size for each tissue layer directly impacts wound tensile strength, scar formation, and infection risk. A layered closure approach — using absorbable sutures for deep tissues and non-absorbable or fast-absorbing sutures for the skin — remains the standard of care.
Key Suture Selection Considerations
Match suture tensile strength duration to the tissue healing timeline — fascia and muscle require 4–6 weeks of support, while skin regains strength within 7–14 days.
Use braided absorbable sutures (e.g., PGA) for subcutaneous and fascial layers where knot security is critical.
Select monofilament sutures for skin closure to reduce capillary wicking and lower infection risk.
In contaminated wounds, monofilament absorbable sutures minimize bacterial harboring compared to braided alternatives.
Gauge selection should follow the principle of using the smallest diameter suture that will hold the wound edges under anticipated tension.
Fast-absorbing sutures eliminate the need for suture removal in pediatric patients and areas where follow-up is difficult.
Recommended Desmo Care Sutures
DesmoNex
PGA braided absorbable suture providing 28–35 days of tissue support — ideal for deep dermal and subcutaneous layers in layered wound closure.
DesmoNex Rapid
Fast-absorbing PGA with 7–10 days of support — suitable for superficial skin closure and pediatric wounds where suture removal is impractical.
DesmoMid
Polypropylene monofilament with the lowest tissue reactivity — preferred for percutaneous skin closure in clean wounds requiring precise cosmetic results.
DesmoCryl
PGCL monofilament absorbable with 21–28 days of support — excellent for intradermal continuous closure with smooth tissue passage.
Clinical Notes & Best Practices
Layered wound closure begins with hemostasis and debridement of devitalized tissue. Deep layers (fascia, subcutaneous tissue) should be approximated with interrupted absorbable sutures placed 5–8 mm apart, burying the knots to prevent suture extrusion. The dermal layer benefits from inverted buried sutures using a braided absorbable material like PGA for reliable knot security. Skin edges are then approximated with either percutaneous interrupted sutures, continuous subcuticular technique, or adhesive strips depending on tension and cosmetic requirements. In high-tension closures, consider a far-near-near-far Smead-Jones technique to distribute forces evenly across the wound. Suture removal timing depends on anatomical location: face 3–5 days, scalp and trunk 7–10 days, extremities 10–14 days.
Frequently Asked Questions
What suture material is best for wound closure?
▼
The best material depends on the tissue layer. Absorbable braided sutures like PGA (DesmoNex) are preferred for deep layers, while monofilament non-absorbable sutures like polypropylene (DesmoMid) or fast-absorbing sutures (DesmoNex Rapid) are preferred for skin closure.
Should I use absorbable or non-absorbable sutures for wound closure?
▼
Use absorbable sutures for any buried layer (fascia, subcutaneous, deep dermis) since they do not require removal. Non-absorbable sutures are used for skin closure when suture removal is planned, while fast-absorbing sutures offer a middle ground by dissolving before requiring removal.
What suture size should I use for wound closure?
▼
Use the smallest suture that will maintain wound closure under expected tension. Common sizes are 3-0 or 2-0 for fascial closure, 3-0 or 4-0 for subcutaneous layers, and 4-0 to 6-0 for skin depending on anatomical location. Facial wounds typically require 5-0 or 6-0 sutures.
How does suture selection affect wound infection risk?
▼
Monofilament sutures harbor fewer bacteria than braided sutures due to the absence of interstices where microorganisms can shelter. In contaminated wounds, monofilament absorbable sutures like DesmoCryl reduce infection risk compared to braided alternatives.
When should fast-absorbing sutures be used for wound closure?
▼
Fast-absorbing sutures like DesmoNex Rapid are ideal for superficial skin closure in children, mucosal wounds, and situations where patients may not return for suture removal. They provide 7–10 days of support before absorption begins.
