Clinicians treating diabetic ulcers are trained in the science and biology of what is happening on a cellular level. Their organized approach to converting a nonhealing wound takes into consideration adequate blood flow and oxygenation, removal of necrotic tissue or bioburden, edema control, and moisture balance. Like stars, all the elements must align to put the wound on the pathway to healing.
The special characteristics of medical grade honey (eg, MEDIHONEY®, Derma Sciences Inc, Princeton, NJ) are applicable to this organized treatment approach. In the past decade, research looking at medical grade honey — using Manuka as a search criteria — and its relevance in advanced wound care has spiked. Made with active Leptospermum honey, MEDIHONEY® dressings provide an osmotic effect. They draw moisture from deeper tissues to bathe the wound environment, cleaning out debris and softening and removing necrotic tissue,1-4 enabling the wound to get back on course for healing. MEDIHONEY® dressings also have a naturally low pH (3.5–4.5), helping modulate wound pH,5-7 a benefit often forgotten because we don’t regularly monitory pH levels. Lowering the pH of the wound environment affects the body’s natural processes that, in turn, can impact protease reduction and increase the supply of oxygen. Both characteristics — osmotic pull and low pH — play key roles in both chronic and acute wound healing.
The following cases represent how MEDIHONEY® is harnessed to heal wounds in patients with diabetes and other comorbidities.
Case 1. A 50+-year-old, noninsulin-dependent woman with diabetes has coronary artery disease and hyperlipidemia. She developed fluid overload where a cane injured her dorsal left foot. She exhibited erythema and fever, was admitted to the hospital, and was provided surgical debridement. MEDIHONEY® Gel was initiated on day 3 to help cleanse the wound and modulate the pH. Within 3 weeks, the MEDIHONEY® treatment had autolytically debrided the wound bed and an amniotic tissue product (AMNIOEXCEL®, Derma Sciences Inc, Princeton, NJ) was applied to advance the healing. By day 79 (2.5 months later), this large wound had greatly reduced in size from 3.0 cm x 3.0 cm x 2.0 cm to 1.7 cm x 2.4 cm x 0.1 cm, and we returned to MEDIHONEY® Gel for final closure. In a little more than 3 months (100 days), the wound was healed with the aid of these 2 therapies (see Figures 1a,b,c).
Case 2. A 56-year old renal transplant patient with diabetes and loss of protective sensation with a medical history including hepatitis A, transient ischemic attack, hypertension, hyperlipidemia, and osteomyelitis had surgery to excise the metatarsal head; the wound dehisced. Treatment included IV antibiotics, 3-layer compression, and absorbent gauze. For the first 28 days, a collagenase ointment was used; however, progress was slow and the wound was not filling in. Treatment was changed to MEDIHONEY®. Over the next 6 weeks, the wound filled in by 50% and within 10 weeks the wound was healed (see Figures 2a,b,c,d).
These positive clinical outcomes are an example of how MEDIHONEY® dressings can be harnessed to aid a scientific and organized approach to wound care. No other product combines these 2 mechanisms of action (ie, high osmotic effect and low pH) in 1 product to provide a timely approach to autolytic debridement and healing.
