The nurse is caring for a patient with a large stasis ulcer. She has just changed the wound dressing and is using a negative-pressure wound system. What can the nurse tell the patient about the functioning of this system?
a. Decreases the amount of angiogenesis
b. Reduces mechanical stretch of tissue
c. Dressing should not need to be changed for 48 hours
d. Helps create a dry environment
C
The dressing is changed on a scheduled basis, usually no earlier than 48 hours. Researchers believe that blood flow increases because of the removal of wound fluid and angiogenesis (development of new blood vessels), and that this stimulates the production of new blood vessels via mechanical stretch of the tissue. The dressing placed into the wound maintains a moist environment to facilitate healing. A suction device is placed over the dressing, and the dressing, suction, and wound area are covered with a transparent dressing, which provides the air-tight seal necessary for negative-pressure wound therapy (NPWT).
