Finger probe test is useful in the diagnosis of necrotizing fasciitis.
:**After infiltrating the area, a 2cm [[incision]] is made down to the [[fascia|deep fascia]].
 
:**[[Fascia]] will be swollen and grey on gross inspection.
*'''Procedure'''
:**Gentle probing with index finger is performed at the level of deep fascia and if the tissue dissects with the minimal resistance, then finger probe test is considered positive.

:***Lack of bleeding
:*[[Fascia]] will be swollen and grey on gross inspection.
:***Lack of normal tissue resistance on finger probe
:*Gentle probing with index finger is performed at the level of deep fascia and if the tissue dissects with the minimal resistance, then finger probe test is considered positive.

Overview

Surgery is the mainstay of treatment for necrotizing fasciitis. Immediate surgical referral remains the only method of reducing mortality and morbidity.

Surgery

Surgery is the mainstay of treatment for necrotizing fasciitis.[1]

  • Indications include:[1]

Finger Probe Test

Finger probe test is useful in the diagnosis of necrotizing fasciitis.

  • Procedure
  • This test is carried out in the ward, emergency room, or in the theater under local or general anesthesia.
  • After infiltrating the area, a 2cm incision is made down to the deep fascia.
  • Fascia will be swollen and grey on gross inspection.
  • Gentle probing with index finger is performed at the level of deep fascia and if the tissue dissects with the minimal resistance, then finger probe test is considered positive.
  • Signs suggesting necrotizing fasciitis include:
    • Lack of bleeding
    • Lack of normal tissue resistance on finger probe
    • Oozing of malodorous "dish water fluid"

Extremities

  • Debridement of the tissue is the main surgical procedure.[2][5]
  • To achieve better surgical wound healing and less scarring, incisions are performed parallel to Langer's lines.[1]
  • Wide resection is performed with boundaries at least as wide as the rim of cellulitis until surrounding healthy bleeding tissue found.
  • After drainage of pus and/or hemorrhagic fluid, ventricle incisions are made, keeping the wound open which allows drainage and removal of additional necrotic tissue.
  • Patients should be closely monitored after surgery and re-exploration with serial debridements, spaced 12 to 36 hours, may be needed to control the infection.
  • The extent and depth of debridement is so extensive that it may involve group of muscles which requires removal of all the muscles.

Amputation

Indications for amputation include:[6][7]

  • Extensive soft tissue necrosis with involvement of the underlying muscles
  • ASA (American Society of Anaesthesiologists) score III and above[8]
  • Shock

Perineal, perianal or scrotal infection

  • A temporary diverting colostomy should be considered to facilitate the decrease need for frequent change of dressings, protect the skin graft for reconstruction and wound hygiene.
  • After scrotal resection, the testes are treated by placing them in pockets in the medial aspects of the thighs.

Abdominal wall infection

Incision:[1]

  • Skin incision is made in the longitudinal direction along the muscle-fascial layers of the inner abdominal wall until healthy tissue is found.

Postoperative management:

  • Serial dressing changes until the wound is free of ongoing or recurrent infection.
  • In the case of progression of infection, aggressive surgical debridement should be repeated.

Extension of infection into the bowel:

  • In cases of extension of infection into the bowel, an exploratory laparotomy is required.
  • Radical surgical debridement at the site of infection and retroperitoneal site is performed followed by partial bowel excision depending on the part of the bowel involved.
  • A diverting colostomy with multiple drainages's of infected abdominal fluid collections is required.
  • Hartmann’s resection is the procedure of choice in patients with perforated colon with peritonitis and in elderly patients with multiple co-morbidities.

Breast and axilla

  • As the axillary region is rich in blood and lymphatic supply, this enables the infection to spread rapidly to distant sites. Hence the delay in surgical debridement proves to be lethal.[9]
  • Care must be taken to avoid contractures.[10][11]

Vacuum-assisted closure device

  • Vacuum assisted closure device is used for faster and effective wound closure.[12][1]
  • Helps wound healing by absorbing excess exudates, reducing localized edema, and finally drawing wound edges together.
