NONCONTACT, LOW-FREQUENCY ULTRASOUND THERAPY* FOR INFECTED PRESSURE ULCERS IN A PATIENT WITH MULTIPLE COMORBIDITIES

This article represents the results of research of low-frequency ultrasound with levocetirizine in patients with acute infectious rhinitis (AIR). Low-frequency ultrasound therapy with levocetirizin effectively reduces rhinitis symptoms (nasal obstruction, sneezing, rhinorrhea) duration, demonstrates anti-inflammatory activity and reduces of topical decongestants requirement in AIR patients. Effectiveness of this therapy was estimated by objective and subjective methods.

Background: A feasibility study was conducted to characterize the effects of noncontact low-frequency ultrasound therapy for chronic, recalcitrant lower-leg and foot ulcerations.Methods: The study was an open-label, nonrandomized, baseline-controlled clinical case series. Patients were initially treated with the Mayo Clinic standard of care before the addition of or the switch to noncontact low-frequency ultrasound therapy. We analyzed the medical records of 51 patients (median ± SD age, 72 ± 15 years) with one or more of the following conditions: diabetes mellitus, neuropathy, limb ischemia, chronic renal insufficiency, venous disease, and inflammatory connective tissue disease. All of the patients had lower-extremity ulcers, 20% had a history of amputation, and 65% had diabetes. Of all the wounds, 63% had a multifactorial etiology, and 65% had associated transcutaneous oximetry levels below 30 mm Hg.Results: The mean ± SD treatment time of wounds during the baseline standard of care control period versus the noncontact low-frequency ultrasound therapy period was 9.8 ± 5.5 weeks versus 5.5 ± 2.8 weeks (P < .0001). Initial and end measurements were recorded, and percent volume reduction of the wound was calculated. The mean ± SD percent volume reduction in the baseline standard of care control period versus the noncontact low-frequency ultrasound therapy period was 37.3% ± 18.6% versus 94.9% ± 9.8% (P < .0001).Conclusions: Using noncontact low-frequency ultrasound improved the rate of healing and closure in recalcitrant lower-extremity ulcerations.

Airborne Ultrasound

The diabetic foot ulcer (DFU) healing rates remain dismally low. Therefore, many adjunctive therapies have been evaluated including ultrasound therapy. The prior studies with noncontact, low-frequency ultrasound were retrospective, single arm, unblinded, or with historical controls. The aim of the present study was to compare the efficacy of noncontact, low-frequency airborne ultrasound (Glybetac) therapy with sham therapy added to standard treatment in patients with neuropathic, clinically infected, or noninfected DFU (wound size >2 cm2), Wagner grades 2 and 3. Patients received ultrasound or sham therapy for 28 days dosed daily for first 6 days followed by twice a week for next 3 weeks along with standard of care. The primary outcome was percentage of patients with at least >50% decrease in wound area at 4 week of intervention. Fifty-eight patients completed the study protocol. The duration of wound was 15.8 ± 11.2 weeks and 12.1 ± 10.9 weeks and wound area of 11.3 ± 8.2 cm2 and 14.8 ± 13.8 cm2 ( P = .507) in the ultrasound and sham groups, respectively. A >50% reduction in wound area was observed in 97.1% and 73.1% subjects ( P = .042) in ultrasound and sham groups, respectively. Wound contraction was faster in the first 2 weeks with ultrasound therapy, 5.3 cm2, compared with 3.0 cm2 ( P = .025) with sham treatment. Overall, wound area reduction of 69.4 ± 23.2% and 59.6 ± 24.9% ( P = .126) was observed at 4 weeks in the ultrasound and sham groups, respectively. We conclude that the airborne low-frequency ultrasound therapy improves and hastens the healing of chronic neuropathic DFU when combined with standard wound care.
