Negative Pressure Wound Therapy Guidelines

Clinical Context and Evidence Base

The American Diabetes Association recommends considering NPWT as one of several adjunctive treatments for chronic ulcers that have failed optimal standard care 5
NPWT demonstrates superior outcomes for post-surgical wounds compared to standard dressings, with 43.2% complete closure versus 28.9% with advanced wound therapy (P = .007) 1
The 2018 WSES guidelines specifically recommend considering NPWT for wound care after complete necrosis removal in necrotizing infections (Grade 1C) 3
The 2018 WSES guidelines recommend NPWT with continuous fascial traction as preferred temporary abdominal closure technique (Grade 2B) 4
NPWT results in superior delayed fascial closure rates compared to non-negative pressure systems 4
For severe peritonitis patients specifically, negative pressure temporary closure showed favorable outcomes in mortality and abdominal closure rates 4
Sharp debridement remains preferable to topical agents as the foundation of wound care 6, 7, 5

The Infectious Diseases Society of America states that for infected wounds, available evidence is insufficient to recommend routine use of NPWT for treatment or prophylaxis 6, 7
NPWT should not be used as a substitute for proper surgical debridement 6, 7
Sharp debridement with scalpel, scissors, or tissue nippers remains the gold standard and is generally preferable to any topical agent 6, 7, 5
