Outpatient Debridement with Low Frequency Contact Ultrasound
This was a prospective, randomized, controlled, clinical study involving 76 subjects with venous ulcers over a 24-week period in an outpatient hospital-based wound care center. The ultrasonic debridement procedures were performed using a low-frequency (22.5 kHz), high-intensity (~60 W/cm2) contact ultrasound device that produces cavitation. Wounds debrided ultrasonically healed significantly faster than wounds debrided with sharp debridement (curettage). The incidence of complete healing was significantly greater (P < .05) after 20 and 24 weeks in subjects receiving ultrasonic debridement.
