Suture Selection for Minor Lacerations

Optimal Suture Material

Monofilament absorbable sutures, such as poliglecaprone or polyglyconate, are the preferred choice for minor lacerations as they reduce infection risk and provide excellent cosmetic outcomes, according to the American College of Surgeons 1, 2
Monofilament sutures cause less bacterial seeding and reduce infection risk compared to multifilament sutures, making them superior for routine wound closure 1, 2
Absorbable options, like poliglecaprone, eliminate the need for suture removal, saving time and reducing patient anxiety and discomfort 1
Polyglyconate provides good tensile strength while maintaining absorbability, making it suitable for high-mobility areas 1, 2
Rapidly absorbing synthetic sutures, such as polyglactin 910, can be considered when faster absorption is desired, though they cost more than standard synthetic sutures, as recommended by the American Journal of Obstetrics and Gynecology 3, 1

4-0 or 5-0 is the appropriate suture size for most routine lacerations, including facial, scalp, and hand wounds, as it provides optimal wound closure without excessive tissue trauma 1, 2, 4

The continuous non-locking subcuticular technique is recommended as it distributes tension more evenly across the suture line, reducing tissue edema and necrosis risk, and results in lower rates of superficial wound dehiscence (RR 0.08; 95% CI 0.02 to 0.35) 1, 2
This technique also provides a better seal against bacterial invasion and minimizes visible scarring through subcuticular closure 2, 4

For hand lacerations, 4-0 or 5-0 monofilament absorbable sutures are recommended due to high mobility in this area, and absorbable sutures are particularly advantageous as removal can be painful in the hand 2, 4
For facial/scalp lacerations, 4-0 or 5-0 monofilament absorbable sutures are appropriate, as recommended by the American College of Surgeons 1, 2

The wound should be kept clean and dry for the first 24-48 hours, and excessive tension on the wound should be avoided during initial healing, as recommended by the American College of Surgeons 1, 2, 4
Follow-up within 24 hours by phone or office visit is recommended to ensure proper healing, and acetaminophen or ibuprofen can be used for pain management 1, 2, 4

Signs of infection, such as increasing pain, redness, swelling, or discharge, should be monitored, as well as pain disproportionate to injury severity, which may suggest deeper complications, as recommended by the American College of Surgeons 1, 2, 4
Wound dehiscence, especially in high-mobility areas, should also be monitored 2

Braided sutures should not be used in contaminated wounds as they increase infection risk, and sutures should not be placed too tightly, which strangulates tissue and impairs healing, as recommended by the American College of Surgeons 2, 4
Inappropriate suture size for the anatomical location should be avoided, and area mobility should be considered when selecting suture material, as recommended by the American College of Surgeons 2, 4
