Management of Dehisced Wound

Immediate Assessment and Initial Management

The American College of Surgeons recommends immediate irrigation of the wound with copious sterile saline or clean tap water, reapproximation of the skin edges without suturing, application of a non-adherent dressing, and monitoring closely for infection over 24-48 hours 1
The initial management of a dehisced wound involves wound preparation, including irrigation with sterile saline or clean tap water to remove debris and reduce bacterial burden, and reapproximation of skin edges using Steri-Strips or similar tension-free methods 1
A non-adherent dressing should be applied to protect the wound while allowing drainage, and aggressive cleansing with antiseptics or antimicrobial dressings should be avoided unless clear infection is present 1

Monitor for specific signs that indicate infection requiring intervention, including fever >38.5°C (101.3°F) or heart rate >110 bpm, expanding erythema >5 cm around the wound margins, purulent discharge with foul odor, and severe pain disproportionate to wound appearance 1
Secondary signs of infection, such as wound bridging, undermining, pocketing, or increased warmth, should also be monitored 2, 3

The American College of Surgeons recommends planning for delayed primary closure or healing by secondary intention rather than immediate resuturing 1
Delayed primary closure may be considered after 3-5 days if the wound shows early granulation tissue and no signs of infection, and Steri-Strip approximation without tension should be continued 1
If any doubt about closure viability, manage with secondary intention healing using dressing changes every 5-7 days, and consider negative-pressure wound therapy (NPWT) for appropriate dressings to reduce fluid loss, limit microbial colonization, control pain, and accelerate re-epithelialization 4, 5, 6

Dressings should be changed every 5-7 days if no complications arise, and appropriate moisture-control dressings (hydrogels, hydrocolloids) should be used to promote epithelialization 1, 2
Collagen matrix dressings may be considered to reduce protease activity and promote fibroblast proliferation 2

The patient should be examined within 24 hours of initial presentation to assess for infection, and continue monitoring for signs of clinical deterioration, extension of dehiscence, or delayed healing 1, 4, 5
If wound conversion occurs (progression to deeper defect) or local sepsis develops, consider surgical debridement followed by biosynthetic xenograft or allograft closure 4, 5, 6

Antibiotics should not be started without clear signs of infection, and indiscriminate prophylactic antibiotics may increase colonization with resistant organisms and Candida 1, 4, 5, 6
Antimicrobial therapy should only be instituted when clinical signs of systemic infection, rising C-reactive protein and neutrophilia, or monoculture on repeat swabs indicating predominant organism are present 4, 5, 6
