Abstract
OBJECTIVES: This case report examines the effectiveness of Mist Ultrasound Healing Therapy® by Celleration, Inc. (Eden Prairie, MN) in promoting wound healing and selective debridement for a deep tissue injury. The patient in this report is an 81 year old male presenting with a necrotic deep tissue injury. METHODS: This patient received Mist ultrasound, a non-contact, low frequency ultrasound (25 to 40 kHz) delivered to the wound bed via fine saline spray, while monitoring for signs of healing. This intervention was given once daily for four consecutive days in the acute setting. The treatment was discontinued due to the patient’s discharge to a skilled nursing facility for short-term rehab. The Mist Therapy® was predicted to assist healing by reducing the area of eschar in the patient’s wound and reducing the entire area of the wound bed. Additionally, greater amounts of healing tissue or epithelialization would be supplanted. The wound is photographed and measured daily before each treatment to help confirm that healing of the wound is taking place. RESULTS: The patient’s total wound area decreased from 14.06cm2 to 9.52cm2 and the area of necrosis decreased from 1.0cm2 to 0.54cm2 after receiving Mist ultrasound. DISCUSSION: Mist ultrasound shows promise toward achieving notable healing of deep tissue injuries. The findings in this case report warrant further investigation of the effects of Mist Therapy® on deep tissue injuries and other wound types.
