BACKGROUND: Disposable negative-pressure wound therapy (NPWT) represents a useful tool to treat difficult healing skin defects in an outpatient setting. In this paper, authors performed a retrospective analysis regarding all patients treated with electrical or mechanical portable NPWT devices.
METHODS: NPWT devices used from November 1st, 2015 to May 1st, 2018 have been considered, for a total of 72 treatments in 53 patients, average age 67 years (median age 73.7 years; IQR 53.8-86.7); all types of ulcers have been treated. The average duration of treatment was 17 days (median duration 14 days; IQR 7-27). We used one model of electrical devices at -125 mmHg (ED125) and two model of mechanical devices at -75 mmHg and -125 mmHg (MD75 and MD125). The type of dressing was identical in the three systems.
RESULTS: In this series no statistical difference has been observed between mechanical and electrical devices (bivariate descriptive analysis with chi-squared or Fisher’s Exact test) in terms of healing, lesion evolution, ability to prepare the wound bed for skin grafts or for the switch to advanced dressings. On the other hand, we have encountered significant difference (P=0.022) for the better ability of devices set at -125 to manage exudates.
CONCLUSIONS: We believe that the choice of the device should be made by evaluating the amount of secretions, the possibility to obtain a good adhesion of the system and, primarily, the compliance of the patient. Both systems represent a valid support for the treatment of difficult healing wounds.
