Management of Small Cheek Laceration with Erythema
For a small scratch to the cheek with surrounding redness but no signs of significant infection, antibiotics are not indicated—wound care alone is sufficient. 1
When Antibiotics Are NOT Needed
The decision to withhold antibiotics is appropriate when the following criteria are met:
- Erythema extends less than 5 cm from the wound edge 1
- Temperature remains below 38.5°C 1
- Heart rate stays below 100-110 beats per minute 1
- White blood cell count is less than 12,000 cells/µL 1
- No purulent drainage is present 1
- Patient is immunocompetent 1
The IDSA guidelines explicitly state that if these minimal criteria are met, antibiotics provide no clinical benefit and are unnecessary. 1 Multiple studies of superficial wounds and abscesses have demonstrated no benefit when antibiotics are added to appropriate wound care. 1
Appropriate Wound Management
Local wound care is the cornerstone of treatment:
- Thorough cleansing of the wound to remove debris and reduce bacterial load 2, 3
- Monitor for signs of progression including increasing erythema, warmth, swelling, or purulent drainage 1
- Elevation of the affected area if any swelling develops 1
When to Reconsider and Add Antibiotics
Antibiotics become indicated if the patient develops any of the following:
- Temperature ≥38.5°C or heart rate ≥100-110 beats/minute 1
- Erythema extending beyond 5 cm from the wound margins 1
- Development of purulent drainage 1
- Signs of systemic inflammatory response syndrome (SIRS) 1
- Evidence of deeper tissue involvement such as bullae, skin sloughing, or necrosis 1
If antibiotics become necessary, a short course of 24-48 hours targeting Staphylococcus aureus and Streptococcus pyogenes is appropriate, with agents such as cephalexin, dicloxacillin, or amoxicillin-clavulanate for facial wounds. 1, 2
Critical Pitfalls to Avoid
Do not prescribe prophylactic antibiotics for simple superficial wounds with minimal erythema, as this provides no clinical benefit and contributes to antibiotic resistance. 1, 4 The evidence consistently shows that drainage and wound care alone are sufficient for superficial infections meeting the criteria above. 1
Watch carefully for rapid progression, particularly within the first 48 hours, as early streptococcal or clostridial infections can present with deceptively minimal local findings but significant systemic toxicity. 1 However, this is exceedingly rare with simple superficial scratches. 1
Flat erythematous changes around minor wounds during the first week without swelling or drainage typically resolve without any treatment, including antibiotics. 1
