Abscess Drained by surgeon: • Abscess in any of the following locations: o Perirectal o Anterior and lateral neck o Hand abscess o Abscesses adjacent to vital nerves or blood vessels o Abscesses in central triangle of face o Breast abscesses • Recurrent or multiple abscesses need surgeon to address/assess for fistula • Patients who are not good candidates for procedural sedation Emphasize the following important features of incision and drainage: ? An abscess may be much larger than it appears on the surface. Thus, it may require a longer incision than the patient expects. ? Scarring should be expected, including the possibility of keloid formation. ? Recurrence is relatively common, particularly in patients with hidradenitis suppurativa or an infected sebaceous cyst. Equipment: ? Sterile gloves, drapes, and 4 x 4 inch gauze ? Goggles or other eye protection (eg, surgical mask with integrated visor) ? Povidone-iodine solution ? Local anesthetic (eg, 1 or 2 percent lidocaine) ? 3 to 10 mL syringe and needle of 25, 27, or 30 gauge ? Culture swab ? Number 11 blade and scalpel holder ? Curved hemostats ? Forceps ? Scissors ? Needleless 30 to 60 mL syringe with 19 gauge IV catheter or needleless irrigation device with splash protection (eg, Zerowet Splashield) ? Basin with sterile saline solution ? Packing material (eg, iodoform or plain gauze packing tape) ? Dressing of choice PACKING After incision and drainage, we suggest packing any abscess cavity that meets any of the following criteria: ? Abscess >5 cm in diameter ? Pilonidal abscess ? Abscess in an immunocompromised or diabetic patient Closure Available evidence is of low quality and does not indicate a clear benefit for primary closure of abscesses over healing by secondary intention. If sutures are placed, close wound follow-up must be assured to evaluate for reaccumulation of pus. Also, primary closure should be avoided in patients with the following conditions: ? Immunocompromise (eg, diabetes mellitus, chronic immunosuppressive therapy, or human immunodeficiency virus infection) ? Signs of systemic infection (eg, fever, chills, hypotension) ? Significant cellulitis (>5 cm of surrounding erythema)
