What is the management approach for fecal matter impact on wound care?

Management of Fecal Matter Impact on Wound Care

The management of fecal contamination in wounds requires a combination of fecal diversion techniques, negative pressure wound therapy, and appropriate wound care protocols to prevent infection and promote healing. 1

Fecal Diversion Options

Temporary Fecal Management Systems

• Rectal diversion devices (silicone tubes) can effectively divert fecal matter away from wounds, protecting them from contamination and reducing the risk of skin breakdown 1
• These devices should be limited to short periods (10-14 days) to avoid intra-rectal damage 1
• Fecal management systems can be used in combination with negative pressure wound therapy (NPWT) for effective isolation of wounds from fecal contamination 1

Surgical Diversion (Colostomy)

• Indicated in cases of:
  • Anal sphincter involvement 2
  • Fecal incontinence preventing wound healing 2
  • Continued fecal contamination despite standard measures 2
  • Deep tissue involvement with repeated contamination 2
• Decision for colostomy should be postponed for at least 48 hours to allow acute inflammation and edema regression 1
• Consider the risk-benefit analysis, as colostomy increases healthcare costs and requires subsequent closure procedure 1, 2

Wound Management Techniques

Negative Pressure Wound Therapy (NPWT)

• NPWT is recommended for wound care after complete removal of necrosis in wounds affected by fecal contamination 1
• Benefits include:
  • Increased blood supply and tissue perfusion 1
  • Reduced edema 1
  • Absorption of fluids and exudates 1
  • Inhibition of infection 1
  • Promotion of granulation tissue formation 1
  • Removal of bacterial contamination 1

Wound Debridement

• Radical surgical debridement of the entire affected area should be performed, continuing into healthy-looking tissue 1
• Cultures of infected fluid and tissues should be obtained during initial surgical debridement to guide antibiotic management 1
• Regular debridement is essential for removing nonviable tissue and promoting healing 1

Wound Care Protocol

• Maintain a moist wound bed while controlling drainage and exudate 1
• Avoid tissue maceration 1
• Use appropriate dressing products that help manage biofilm 1
• Perform repeated wound assessments to evaluate healing progress and identify signs of infection 1

Special Considerations

Perianal and Sacral Wounds

• Particularly challenging due to proximity to the source of contamination 2, 3
• Fecal management systems have been successfully used for perianal wounds when colostomy is not preferable or contraindicated 3
• For sacral pressure injuries, consider early fecal diversion to prevent continued contamination 2

Multidisciplinary Approach

• Involve general/emergency surgeons, urologists, intensivists, and plastic surgeons early in the decision-making process 1
• Consult wound and ostomy nurses for specialized wound care expertise 2
• Consider plastic surgery for complex wound closure once infection is controlled 2

Complications to Monitor

• Risk of continued contamination despite interventions 4
• Potential for device-related complications with fecal management systems 4
• Increased healthcare costs associated with temporary stoma formation 1

By implementing appropriate fecal diversion techniques and wound care protocols, healthcare providers can effectively manage wounds affected by fecal contamination, prevent infection, and promote optimal healing.
