Which condition is a contraindication for using a negative pressure system?

• A. On a wound with infection, necrosis, malignancy, fistulas, osteomyelitis, or visible arteries/veins in the wound
• B. On a wound with healthy granulation tissue
• C. On a closed surgical incision
• D. On a wound with no drainage

Answer: (A)

Negative pressure wound therapy should not be used when the wound has conditions that make suction unsafe or won’t allow healing to occur. The presence of infection with necrotic tissue, malignancy within the wound, a fistula, osteomyelitis, or exposed major vessels/arteries or veins creates real risks—infection can be trapped and spread, necrotic tissue won’t be adequately cleared, cancer cells could be disseminated, fistulas can worsen drainage or contaminate adjacent areas, and exposed vessels can bleed severely under suction. Because of these risks, using a negative pressure system is contraindicated in such wounds. If a wound shows healthy granulation tissue, a closed surgical incision, or no drainage, these scenarios do not by themselves rule out NPWT and may be appropriate candidates depending on the overall clinical picture.
