OxyBand Dressing Accelerates Wound Healing

TM
OxyBand treated wounds and 8.8 days + 0.7 for placebo treated wounds. The
difference between the means was 2.6 days faster on the OxyBand side. A difference
TM
TM
was significant at p < .001. OxyBand treated wounds healed 28.4% faster as
measured by % epithelialization compared to placebo treated wounds on the same
subject.

TM
There was a dramatic difference in amount of exudate between the OxyBand
and the placebo treated wounds on days 3 (Photos 3A & 3B, R and B on arms = Red

and Blue coded dressings) through 7. Table 2 also shows a significant difference in the

mean scores for exudate. On day 3, the mean exudate was essentially twice as much
for the placebo treated wounds when measured on the 5-point scale compared to the

TM
OxyBand treated wounds. Beyond this time, there was no significant exudate in either
wound, the mean difference between the groups was .77 score (on a 1 to 5 scale for

exudate) or significantly more exudate for the placebo treated wounds compared to the
OxyBand treated wounds.
TM
Redness on the placebo wounds was greater, especially in the initial days of

evaluation (Table 2). The placebo treated wounds were significantly redder, mean score
1.09 out of a 5 point scale for the placebo treated wounds compared to .29 for the

TM
OxyBand treated wounds over follow up evaluations. The difference between the
means for the mean redness scores was significant; placebo treated wounds had a

mean redness score that was .80 greater than the OxyBand treated wounds on a 5-
TM
point scale.
Mean pain scores also indicate significantly greater pain in placebo wounds

TM
compared to OxyBand treated wounds. The mean pain score for placebo was nearly
TM
3 times greater than OxyBand wounds on day 3 (Table 2). Mean pain scores
continued to be significantly greater for the placebo treated wounds compared to the

OxyBand treated wounds on days 5 and 6.
