Abstract
PURPOSE: The purpose of this technologic analysis was to critique technologic features of devices designed to deliver negative pressure wound therapy with instillation or irrigation (iNPWT).
APPROACH: Published literature regarding negative pressure wound therapy (NPWT) devices with the added feature of instillation or irrigation was reviewed to provide an overview of iNPWT. Varied features of devices currently available in the United States were described based on instructions published by individual manufacturers. Safety information regarding iNPWT was derived from the Manufacturer and User Facility Device Experience (MAUDE) Database.
CONCLUSIONS: The additional option of instillation or irrigation available with some NPWT devices may provide clinical benefits in carefully selected patients. Advantages may be related to facilitated removal of thick exudate and necrotic tissue. Devices with instillation options are indicated for inpatient settings, with ongoing monitoring of health care professionals. A simpler device with an intermittent irrigation option may be used in the home setting, with proper supervision. More research is needed to demonstrate the clinical effectiveness and cost of the therapy.
