A study, published in the Journal of Arthroplasty, examined the effectiveness of closed incision negative pressure therapy through the Prevena Incision Management System.
Researchers conducted a single center, open-label study of 592 patients undergoing either total knee arthroplasty or total hip arthroplasty treated with ciNPT on clean surgical wounds. Researchers treated the incisions of 169 patients with the Prevena system and 400 patients with traditional gauze dressing.
Here's what they found:
1. The Prevena group experienced significantly decreased infection rates (1 percent versus 3.5 percent in the gauze group).
2. The Prevena group had a lower overall complication rate (1.5 percent as compared to 5.5 percent among gauze group patients).
3. Patients treated with the Prevena system were four times less likely to experience a surgical site complication.
4. Prevena-treated patients also had lower pain scores at 24 hours postoperation than the gauze group.
