Perspectives for wIRA for the
improvement of healing of acute wounds

As far as perspectives for the use of wIRA are concerned, it seems clinically prudent to use wIRA both pre- and postoperatively, e.g. in abdominal and thoracic opera-tions. wIRA can be used preoperatively (e.g. over 1–2 weeks) to precondition donor and recipient sites of skin flaps, transplants or partial-thickness skin grafts, and postoperatively to improve wound healing and to decrease pain, inflammation and infections at all mentioned sites. wIRA can be used to support routine pre- or intraoperative antibiotic administration or even a replacement of the latter with wIRA can be discussed under certain conditions [2].

wIRA for wound seromas

During rehabilitation after hip and knee endoprosthetic operations the resorption of wound seromas and wound hematomas was both clinically and sonographically faster and pain was reduced by irradiation with wIRA(+VIS) [2]. An additional example is presented in Figure 12.

Figure 12: Example of a successful treatment of recurrent wound seromas with wIRA
A 64 year-old female patient had relapsing wound seromas and wound hematomas (without infection) after a hip operation
(replacement of the acetabulum part of a 15 year-old endoprosthesis) even after an additional operation with the sole intention of stopping the wound seromas and after approximately 8 aspirations of seroma fluid (up to approximately 90 mL within one aspiration) within 2 months, and a third operation was seriously considered: Figure A shows the sonographic state. At that time, wIRA(+VIS) irradiation was commenced, beginning with 30 minutes twice per day and increasing up to 3 times one hour per day. Within a few days the seroma no longer increased as usual; after approximately one week a slight decrease of seroma size was noticed clinically (Figure B). Figure C shows reduced seroma size after 18 days and Figure D after 29 days. After approximately 2 months the seroma had resolved completely (both clinically and sonographically) without any aspiration of seroma fluid or operation since commencement of wIRA(+VIS) irradiation (sonographic pictures published with kind approval of Dr. Michael Paulus, Herzogenaurach, Germany) (from [2]).

wIRA for persistent postoperative pain

wIRA can be used successfully for persistent postopera-tive pain e.g. after thoracotomy [2].
