• Allows rapid access for re-entry
• No sutures required for placement
• Provides separation between the abdominal wall and viscera, protecting abdominal contents
• Allows rapid access for re-entry and does not require sutures for placement
• Perforated foam dressing actively facilitates drawing wound edges together


The 3M™ AbThera™ Advance Open Abdomen Dressing is indicated for temporary bridging of abdominal wall openings where primary closure is not possible and/or repeat abdominal entries are necessary. Intended use of this system is for use in open abdominal wounds, with exposed viscera, including but not limited to abdominal compartment syndrome. The intended care setting is a closely monitored area within the acute care hospital, such as the ICU. The abdominal dressing will most often be applied in the operating theater.


Contraindicated for use on patients with open abdominal wounds containing non-enteric unexplored fistulas. Protect vital structures with 3M™ AbThera™ Fenestrated Visceral Protective Layer at all times during therapy. Never place exposed foam material directly in contact with exposed bowel, organs, blood vessels, or nerves.

Warnings and Precautions

Key Warnings (for all warnings, refer to Instructions for Use):
-Not for use with instillation therapy.
-Do not substitute, alter or breach the tubing set.
-Monitor closely for bleeding.
-Monitor for intra-abdominal pressure. If IAH/ACS persists, discontinue AbThera Therapy and address underlying
condition as medically indicated.
-3M™ AbThera™ Fenestrated Visceral Protective Layer or 3M™ AbThera™ Visceral Protective Layer should completely cover all exposed viscera and completely separate the viscera from
contact with the abdominal wall.
-Formation of adhesions may reduce the likelihood of fascial reapproximation and increase risk of fistula development,
common complications in patients with exposed viscera.
Key Precautions (for all precautions, refer to the Instructions for Use):
-When using intra-abdominal packing with the AbThera (NPT) System, packing material may be drier than anticipated.
-Monitor fluid output: the volume of exudate in the canister and tubing should be frequently examined.
-Patient size and weight: Use lower negative pressure for elderly/small patients at risk for fluid depletion or
dehydration; monitor fluid output including volume in tubing and canister.
