Suture Material and Size for Routine Lacerations in Primary Care
Optimal Suture Material Selection
- Monofilament sutures are preferred over multifilament (braided) sutures as they cause less bacterial seeding and may reduce infection risk in mobile areas 1, 2
- Absorbable monofilament options provide several advantages, including poliglecaprone (MONOCRYL) which is excellent for routine lacerations due to minimal tissue reactivity 2
- Absorbable sutures maintain 50-75% of tensile strength after one week, providing extended wound support 3
Suture Size Recommendations
- For most routine lacerations: 4-0 or 5-0 suture size is appropriate 1, 2
- For hand lacerations: 4-0 or 5-0 is typically recommended 1
- For scalp lacerations: 4-0 or 5-0 is generally appropriate 4
Suturing Technique
- Continuous non-locking subcuticular suturing technique is preferred over interrupted sutures as it distributes tension more evenly across the suture line, results in lower rates of superficial wound dehiscence (RR 0.08; 95% CI 0.02 to 0.35), and provides better seal against bacterial invasion 3
- Avoid overly tight sutures that can strangulate wound edges 3
Anatomical Considerations
- Hand lacerations require special attention, with longer suture retention times (10-14 days) needed due to high mobility 1
- Thumb webbing specifically benefits from extended suture duration (12-14 days) 2
- Subcuticular closure minimizes visible scarring 2
Post-Repair Care Instructions
- Keep the wound clean and dry for the first 24-48 hours 2
- Avoid excessive tension on the wound during initial healing 2
- Use acetaminophen or ibuprofen for pain management 5
- Follow up within 24 hours either by phone or during an office visit to ensure proper healing 1
Complications to Monitor
- Signs of infection: increasing pain, redness, swelling, or discharge 4
- Pain disproportionate to injury severity may suggest deeper complications 4
- Monitor for wound dehiscence, especially in high-mobility areas 3
