Potential Complications?
- cellulitis of collection of pus
- bacteremia and septicemia if inadequately treated
- perianal abcess incison and drainage fequently results in a chronic anal fistula up to 50% time
- infections of the palmar aspect of the hand can extend from superfical to deep tissue via palmar fascia
- Deep infection should be suspected when simple I and D fails to reduce swelling, redness, pus or pain

2. To keep it open so that it can drain
simple abscess?
cut open and drain
complex abscess?
- cut open
- explored and packed it
- 3 to 4 times more costly than a simple abcess
treatment of abscesses?
Small abscess may respond to warm compresses or antibiotic therapy
If no better, consider I & D
Obtain culture if possible
patient preparation?
Notify patient of benefits and risks
Discuss post procedure care as well
Provide opportunity for question/answer period
Comfortable/supine position
special consideraiton
Primary management of abscesses should be incision and drainage with routine culture
Antibiotic therapy not indicated for typical abscesses in patient with normal defenses
Abscesses requiring antibiotics are those with surrounding cellulitis or lymphangitis
antibiotic must cover what organism?
staphylococcus until cultures back
pain relief
May require acetaminophen or NSAID.
Narcotics rarely needed (if taking the scalpel to them)
Procedure alone generally provides sufficient pain relief
follow up care instructions?
Warm wet soaks to area four to six times a day for 5-7 days.... or warm bath tubes...clean first and after (isolated bath tube) the tube
Nonadherent dressing should be applied over wound (Adaptic, Telfa)
Motion may interfere with healing
Elevate injured extremity-improves venous and lymphatic drainage, helps control swelling, pain and edema
follow up and care instructions cotninued?
Wound must be kept clean and dry
Remove dressing in 2 days
Replace with dry, sterile dressing.
Change dressing daily
Needs follow-up for packing changes-some patients
Watch for signs of recurrence or cellulitis
Notify provider immediately if any redness, drainage, pus, fever, chills or swelling
