Treatment of Minor Wound Infections

Initial Assessment and Wound Care

The American Heart Association recommends thorough wound cleansing with running tap water or sterile saline, followed by application of an occlusive dressing, and medical evaluation if signs of worsening infection develop 1, 2
Thoroughly irrigate superficial wounds until there is no obvious debris or foreign matter in the wound 2
Use running tap water or sterile saline solutions for wound irrigation instead of antiseptic agents such as povidone-iodine 1, 2
After cleaning, cover clean superficial wounds with an occlusive dressing to promote wound healing 1, 2
Occlusive dressings result in better wound healing than dry dressings and maintain a moist wound environment essential for optimal healing 2

If redness, swelling, foul-smelling wound drainage, increased pain, or fever develops, remove the dressing, inspect the wound, and obtain medical care 1, 2
These signs indicate potential infection progression requiring professional evaluation 2

For mild superficial infections, first-line antibiotic options include amoxicillin-clavulanic acid, cloxacillin, and cefalexin 3, 4
Incision and drainage is the primary treatment for simple abscesses or boils, often without requiring antibiotics 5

Animal or human bite wounds or wounds contaminated with saliva should be evaluated in a medical facility as soon as possible 1, 2
For animal bites, amoxicillin-clavulanic acid is the recommended oral treatment 3, 4
For diabetic wound infections, antibiotic selection should be based on infection severity and likely pathogens 5

For mild infections, antibiotic therapy typically lasts 1-2 weeks 5
Antibiotics should be continued until resolution of infection signs, not through complete wound healing 6

Treating clinically uninfected wounds with antibiotics is unnecessary and may contribute to antibiotic resistance 6
Using antiseptic irrigation offers no advantage over sterile saline or tap water 1, 2
Continuing antibiotics through complete wound healing rather than just until resolution of infection signs 6
Failing to obtain proper cultures before starting antibiotics in moderate to severe infections 6
