Suture Selection for Minor Lacerations
For minor lacerations, use monofilament absorbable sutures (such as poliglecaprone/MONOCRYL or polyglyconate/Maxon) in 4-0 or 5-0 size, as they reduce infection risk, eliminate the need for removal, and provide excellent cosmetic outcomes. 1, 2
Optimal Suture Material
Monofilament absorbable sutures are the preferred choice for the following reasons:
- Monofilament sutures cause less bacterial seeding and reduce infection risk compared to multifilament (braided) sutures, making them superior for routine wound closure 1, 2
- Absorbable options eliminate the need for suture removal, saving time and reducing patient anxiety and discomfort 1, 3
- Poliglecaprone (MONOCRYL) demonstrates minimal tissue reactivity and is excellent for routine lacerations 2
- Polyglyconate (Maxon) provides good tensile strength while maintaining absorbability 1, 2
- Rapidly absorbing synthetic sutures like polyglactin 910 (VICRYL RAPIDE) can be considered when faster absorption is desired, though they cost more than standard synthetic sutures 4, 1
Materials to Avoid
- Catgut sutures should be avoided as they are associated with more pain and higher risk of requiring resuturing 4, 1
- Standard synthetic multifilament sutures may require removal if non-absorbable material persists 4
Suture Size Selection
- 4-0 or 5-0 is appropriate for most routine lacerations including facial, scalp, and hand wounds 1, 2, 5
- This size provides optimal wound closure without excessive tissue trauma 1, 2
Suturing Technique
Use continuous non-locking subcuticular technique rather than interrupted sutures:
- Distributes tension more evenly across the suture line, reducing tissue edema and necrosis risk 1, 2
- Results in lower rates of superficial wound dehiscence (RR 0.08; 95% CI 0.02 to 0.35) 2
- Provides better seal against bacterial invasion 2
- Minimizes visible scarring through subcuticular closure 2, 5
Technical Considerations
- Use the "small bite" technique (approximately 5mm from wound edge and between stitches) to ensure adequate tension distribution and minimize tissue damage 5
- Avoid overly tight sutures that can strangulate wound edges and impair healing 2, 5
Location-Specific Modifications
Hand Lacerations
- Use 4-0 or 5-0 monofilament absorbable sutures due to high mobility in this area 2, 5
- Absorbable sutures are particularly advantageous as removal can be painful in the hand 5
- Consider polyglyconate for good tensile strength in this high-mobility area 5
Facial/Scalp Lacerations
- 4-0 or 5-0 monofilament absorbable sutures are appropriate 1, 2
- No difference in long-term cosmetic results between absorbable and permanent sutures in clean facial wounds 3
Post-Repair Care
- Keep wound clean and dry for first 24-48 hours 1, 2, 5
- Avoid excessive tension on the wound during initial healing 2, 5
- Follow up within 24 hours by phone or office visit to ensure proper healing 1, 2, 5
- Use acetaminophen or ibuprofen for pain management 2
Complications to Monitor
- Signs of infection: increasing pain, redness, swelling, or discharge 1, 2, 5
- Pain disproportionate to injury severity may suggest deeper complications such as periosteal penetration 1, 2, 5
- Monitor for wound dehiscence, especially in high-mobility areas 2
Common Pitfalls to Avoid
- Do not use braided sutures in contaminated wounds as they increase infection risk 2
- Do not place sutures too tightly, which strangulates tissue and impairs healing 2, 5
- Do not use inappropriate suture size for the anatomical location 2
- Do not fail to consider area mobility when selecting suture material 2, 5
