Effect on healing rates of wounds treated with direct cold atmospheric plasma: a case series.

Objective: The response of different critical acute and hard-to-heal wounds to an innovative wound care modality-direct application of cold atmospheric plasma (CAP)-was investigated in this clinical case series.

Method: Over an observation period of two years, acute wounds with at least one risk factor for chronification, as well as hard-to-heal wounds were treated for 180 seconds three times per week with CAP. CAP treatment was additional to standard wound care.
