301ULTRASOUND IRRADIATION SURGERY IN ELDERLY PRESSURE ULCER PATIENTS: EFFICACY AND MECHANISMSThis study aimed to assess the efficacy of ultrasound irradiation as an adjunct to standard care in reducing wound size and exudate weight in elderly patients with pressure ulcers. Five elderly patients (two males and three females, aged 76 to 92) with seven ulcers were included in an ABABA study design, following National Pressure Ulcer Advisory Panel (NPUAP) recommendations for stage III or IV pressure ulcers. Ultrasound irradiation was administered alongside moist wound healing dressing (A) in alternating treatment periods, with sham ultrasound used as a control (B). Ultrasound pulses of 1MHz or 3MHz at 20% duty cycle were applied five times a week for 2–4 weeks. Results showed a significant reduction in ulcer size in the treatment group compared to controls, with increased exudate weight observed during sham ultrasound periods. These findings suggest that ultrasound may promote pressure ulcer healing when used in conjunction with standard care, though further research is warranted to determine effectiveness and underlying mechanisms]]>1122021Ultrasound irradiation, Pressure ulcers, Elderly patients, Wound healing, ExudateDr G Uday Kiran, Dr Ajeya JoshiAssociate Professor, Department of General Surgery, Great Eastern Medical School & Hospital, Ragolu, Srikakulam, India 2Associate Professor, Department of General Surgery, Nimra Institute of medical sciences, Jupudi, Vijayawada, India
