3M™ AbThera™ Open Abdomen Negative Pressure Therapy

AbThera Therapy is designed to:

• Actively remove fluid and help reduce edema^1,2
• Provide medial tension, which helps minimize fascial retraction and loss of domain^2,3,4
• Help protect abdominal contents from external environment
• Provide separation between the abdominal wall and viscera, protecting abdominal contents
• Allows for rapid access for re-entry and does not require sutures for placement

3M™ AbThera™ Advance Open Abdomen Dressing
The next generation in temporary abdominal closure

Under negative pressure, the unique configuration of the 3M™ AbThera™ Advance Perforated Foam is designed to collapse medially while maintaining its vertical rigidity⁵.

In a comparative study^5,6 of 4 healthy pigs with an open abdominal wound that were treated with 3M™ AbThera™ SensaT.R.A.C.™ Open Abdomen Dressing and AbThera Advance Dressing at -125mmHg for 5 minutes, 82 measurements over 28 placements demonstrated that the AbThera Advance Dressing had a difference in the following:

• 31% increase in overall tissue movement (N=82, p<0.005)
• 39% increase in skin movement (N=42, p<0.05)
• 20% increase in fascia movement (N=40, p<0.05)

In this animal study, NO change in intra-abdominal pressure was observed when negative pressure was applied.

• No correlation to humans can be made
