Diabetic foot ulcer: 2,5 year old wound on the heel improves with PLASOMA cold plasma, in a tropical environment

Patient introduction, recovery course prior to PLASOMA

An 86-year-old African woman from the USA went to St Maarten to visit family. She had a wound on the lateral (outer) side of her left heel for 2.5 years. She has been under the treatment of a surgeon in the USA for 2 years. She has peripheral arterial disease and has been receiving regular antibiotics for her wound. Unfortunately, the wound has not reduced much in size over the past 2 years. She reported to the clinic in St Maarten on 5 November 2022 with a request to have a look at her wound as she would be staying on the island for about 6 weeks.

She is known to have type 2 diabetes mellitus for which she is taking Repaglinide and Metformin. Due to diabetes, she has considerable neuropathy in her feet, and has many complaints of painful tingling. For this she uses Gabapentin. She also uses Metoprolol, Losartan, Cyclobenzaprine, Loratadine and Meloxicam. The wound developed when she spent a lot of time in bed. She sleeps with her left ankle on a pillow to reduce the pressure on the wound. She started PLASOMA cold plasma treatment on 8 November 2022 in the hope that the wound will respond to it.

Results and frequency PLASOMA cold plasma treatment

• PLASOMA cold plasma treatment: 2 times per week, 9 Cold plasma treatments in total.

• Increase in new epithelial tissue. The wound size reduced with 90% in 4 weeks.
