CHAPTER FIFTEEN. Negative Pressure Wound Therapy
The principle of ______________________ is defined as the stimulation of cells within the wound bed with mechanical force, thus stimulating them to reproduce.
A wound referred for NPWT has a 7 cm sinus at the lateral border. Which of the following dressings is the best choice for filling the sinus?
a. Black reticulated foam
c. White, nonadherent foam
d. No dressing needs to be put in the sinus
You place an NPWT dressing on a patient with a large abdominal wound after hernia repair. The recommended pressure setting would be
b. 125 mmHg—the pressure that is recommended as producing the fasted wound closure
c. 150 mmHg—recommended because of the wound size and the presence of hernia mesh in the wound bed
d. The pressure between 75 and 125 mmHg that is most comfortable for the patient and adequately removes the wound exudates
Which of the following is an indication to delay application or discontinue the use of NPWT?
a. The wound shows evidence of bleeding that does not stop with pressure.
b. The patient complains of the inconvenience of carrying the pump.
c. The wound size has decreased 50%.
d. The wound is more than 70% granulated.
Your patient calls to tell you that the NPWT pump stopped working during the night, and the patient has not been able to reestablish good suction. Your advice to the patient is
a. Add extra drape to the edges and come in for the regularly scheduled appointment the next day.
b. Remove the dressing, apply dry gauze, and come in the next day.
c. Seal the wound to prevent fluid leakage and come in as soon as possible so that the dressing can be removed, the wound cleansed and assessed, and a new NPWT dressing applied.
