Changing negative pressure wound dressings in open abdomen - general and visceral surgery

After removing the old NPWT dressing, prepping and sterile draping of the surgical field, inspect the abdomen and resolve any adhesions between the intestinal loops.

Extensive irrigation and lavage of the abdomen.

Tip: Depending on local findings and underlying condition, respectively, the procedure may need to be extended.

Moisten the intra-abdominal component (perforated film with integrated sponge) of the NPWT system and insert it into the abdomen with moist dissecting sponges.

Tip: Ensure that the film is inserted as deeply into the abdomen as possible and that it separates the abdominal wall from the bowel. Around the liver and the ligament or a stoma, the intra-abdominal film may need to be incised in order to insert it well deep into the abdomen without wrinkling.
