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 study5,6 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:
In this animal study, NO change in intra-abdominal pressure was observed when negative pressure was applied.
