Evaluation of Human Amniotic Membrane as a Wound Dressing for Split-Thickness Skin-Graft Donor Sites
Figure 7
Box plot diagrams illustrate the results of a comparison between group A (wounds treated with HAM, ), group B (first control group of wounds, covered directly and solely by polyurethane foam), and group C (second control group of wounds in which polyurethane foil and consecutive paraffin gauze served as a cover of the STSG-donor site). (a) shows the exudation of ichor on a scale from 0 to 4 (0 = dry; 1 = visible exudate; 2 = moist visible exudate; 3 = wet exudate visible; 4 = dripping exudate visible). (b) shows the overall required amount of dressing changes during the first 14 postoperative days. (c) shows the relative pain sensation value (visual analog pain scale: 0 = no pain to 10 = unbearable pain) during dressing changes recorded by the patients. (d) shows the mean of pruritus development during the first 14 days of wound-healing (0 = no itching; 1 = light; 2 = moderate; 3 = strong; 4 = very strong). (e) shows evaluation of comfort as reported by the patients (0=excellent; 1 = well; 2 = satisfactory; 3 = uncomfortable; 4 = inacceptable).
