OxyGenesys Dissolved Oxygen Dressing and Gauze Dressing
OxyGenesys Dissolved Oxygen Dressing is a closed-cell foam wound dressing enriched with gaseous and dissolved oxygen for use in the management of wounds. Standard Gauze Dressing: A sterile 4x4 covered by an adhesive Tegaderm will serve as the comparator for this study. Each study participant acted as her own control (one breast of each participant was treated with OxyGenesys, while the other breast was treated with the standard dressing (control)).

Each study participant was supposed to act as her own control (one breast to be treated with the test article, the other breast with the control article).

SECONDARY outcome

Timeframe: 30 days post nipple-sparing mastectomy

Population: Each participant acted as her own control - one breast received OxyGenesys, while the other breast received the standard dressing. Two patients in the OxyGenesys study arm, and one patient in the Control study arm did not provide follow-up data.

Patient and Observer Scar Assessment Scale - range = 1 - 10. "1" is best condition ("normal skin") and "10" is worst condition ("worst scar imaginable"). The scale is used to assess each of six different wound characteristics, including vascularity, pigmentation, thickness, relief, pliability, and surface area. The means of these combined scores and their respective standard deviations are reported for each study group. The range of the final evaluation score, based on the collective evaluation of each of the six wound characteristics is "6" (if each of the six scores equals "1") to "60" (if each of the six scores equals "10").

SECONDARY outcome

Timeframe: 30 days

Population: There is just one NRS value calculated for the indicated time-frame, and thus a comparison between study groups with respect to this outcome was not made. The single NRS value at 30 days is reported here. One patient did not provide follow-up data at this time-point, and thus the total number of participants is 26 instead of 27 for this outcome.

Numerical Rating Scale (NRS) - range = 0 - 10. "0" corresponds to "no pain" and "10" indicates "worst pain imaginable". The means of these scores and their respective standard deviations are reported for each study group.
