Incision and drainage
(Redirected from Incision and Drainage)
Indications
- Abscess of skin or superficial soft tissue
Contraindications
- No absolute contraindications
- Abscesses that may require OR management or specialist consultation include[1]:
- Large or deep abscesses that are difficult to access or anesthetize
- Abscesses of the palms, soles, or nasolabial folds
- Areas in which cosmesis is important (face, breast)
Equipment Needed
- PPE
- Local anesthetic
- Incision and Drainage Tray:
- Scalpel
- Hemostat
- Forceps
- Gauze
- Drape / towel
- Iodine swabs

Lidocaine | 5 mg/kg (max 300mg) | 7 mg/kg (max 500mg) | 30-90 min |
|
Mepivicaine | 7 mg/kg | 8 mg/kg | ||
Bupivicaine | 2.5 mg/kg (max 175mg) | 3 mg/kg (max 225mg) | 6-8 hr |
|
Ropivacaine | 3 mg/kg | |||
Prilocaine | 6 mg/kg | |||
Tetracaine | 1 mg/kg | 1.5 mg/kg | 3hrs (10hrs with epi) | |
Procaine | 7 mg/kg | 10 mg/kg | 30min (90min with epi) |
Procedure[1]
Standard Technique
Sterile technique recommended, but not required
- Cleanse skin overlying and surrounding abscess site with chlorhexidine or Iodine
- Anesthetize skin of planned incision site
- Local anesthesia
- Field block
- Regional block
- In some cases, procedural sedation may be indicated
- Make a linear incision (along skin tension lines) over the center of the abscess cavity
- Advance depth until abscess cavity entered
- Ensure incision is large enough to accommodate drainage and introduction of forceps/hemostat
- Manually express contents
- Introduce hemostat and bluntly dissect to break up loculations
- Packing with iodoform gauze may be performed (goal is to prevent premature wound closure), however evidence indicates that packing is not necessary.[2][3]
Irrigation of abscess cavity has no benefit[4]
LOOP Technique
- Incise at most fluctuant area of abscess
- Incise second location <4cm from original incision
- For larger abscesses can repeat this step thus creating several LOOPs.
- Break-up loculations with hemostat
- Irrigate wound
- Pass hemostat through both incisions and pull penrose through
- Tie penrose drain loosely over 30cc syringe to form LOOP
- Patient can follow up with primary care provider or cut in 5-7 days
- Retrospective study showed decreased failure rate in LOOP technique vs standard I&D. [5]
Complications
- Damage to surrounding structures
- Progression of infection
- Transient bacteremia
Follow-up
- Wound check in 1-2 days.
- Warm soaks to help facilitate ongoing drainage
- 7-day course of Trimethoprim–Sulfamethoxazole has been shown to decrease treatment failure[6]
- Previously antibiotics were indicated only for 1) overlying cellulitis; 2) evidence of systemic infection[7]; for immunosuppressed patients; or abscess that does not respond to standard treatment [8]
- Clindamycin shown to be as effective as TMP/SMX, but with higher adverse events[9]
