Enzymatic Debridement in Burns Patients: A Comparison to Standard of Care
Enzymatic Debridement in Burns Patients (Children & Adults): A Comparison to Standard of Care (Protocol MW 2004-11-02)

Burns represent one of the most severe and dreaded traumas. Burned and traumatized tissue is known as eschar. The dead eschar, if not removed, often becomes heavily contaminated and is the source of local and/or systemic infection or sepsis. The local inflammation and infection destroy healthy surrounding tissues and extends the original damage. In order to prevent these complications, and in order to minimize the risk of infection, it is imperative to evaluate the burn and remove all of the offending eschar at the earliest possible opportunity. This removal of dead tissue is termed "debridement".

The most direct debridement method for eschar removal is surgery. Traditional, conservative non-surgical debridement is a lengthy process which often involves many complications.

The objective of this study is to evaluate the safety and enzymatic debriding efficacy of Debrase Gel Dressing (DGD) in hospitalized patients with deep partial thickness and/or full thickness thermal burns and to compare DGD to standard of care (SOC).

Inclusion Criteria:

  1. Males and females between 4 years to 55 years of age,
  2. Thermal burns caused by fire/flame, scalds or contact,
  3. Deep partial thickness (mixed deep dermal) and/or full thickness (3°) burn wounds ≥ 5% and ≤ 30% Total Body Surface Area (TBSA); all these wounds must receive study treatment,
  4. At least one wound of ≥ 2% TBSA deep partial thickness and/or full thickness burn,
  5. Total burn wounds ≤ 30% TBSA,
  6. Signed written informed consent.

Exclusion Criteria:

  1. Deep partial thickness and/or full thickness facial burn wounds, > 0.5% TBSA; study treatment of facial burns is not allowed,
  2. Study treatment of perineal and/or genital burns (A patient with these wounds may be enrolled but the wounds may not be designated as target wounds),
  3. Circumferential anterior/posterior trunk full thickness fire/flame burns, > 15% TBSA, (Circumferential is defined as encircling ≥ 80% of the trunk circumference.)
  4. Pre-enrollment escharotomy,
  5. Heavily contaminated burns or pre-existing infections,
  6. Signs that may indicate smoke inhalation,
  7. General condition of patient would contraindicate surgery,
  8. Pregnant women (positive pregnancy test) or nursing mothers,
  9. Poorly controlled diabetes mellitus (HbA1c>9%),
  10. Cardio-pulmonary disease (MI within 4 weeks prior to injury, pulmonary hypertension, COPD or pre-existing oxygen-dependent pulmonary diseases),
  11. Pre-existing diseases which interfere with circulation (PVD, edema, lymphedema, surgery to the regional lymph nodes, obesity, varicose veins),
  12. Immediate life threatening conditions (such as immuno-compromising diseases, life threatening trauma, severe pre-existing coagulation disorder, cardiovascular, liver or neoplastic disease),
