Lesions that appear superficial can often have associated abscess formation that is not clearly appreciated without debridement of the wound or, on occasion, additional

At the time of I&D, a sample should be obtained for culture and sensitivity testing. Superficial wound swabs of the purulent drainage prior to I&D is of limited utility and NOT recommended.

Antibiotics are an adjunct to I&D in the management of uncomplicated skin abscesses caused by CA-MRSA.

Antibiotic therapy should be given BEFORE I&D in patients with prosthetic heart valves
or other conditions placing them at high risk for endocarditis.
