Chronic venous leg ulcers are difficult to treat and recurrences are common. Among various modalities of treatment, platelet-rich fibrin (PRF) has shown promising results in ulcer healing by providing necessary growth factors. Unna's paste dressing has also proven to enhance wound healing.
The aim of this study is to compare the efficacy of autologous PRF versus Unna's paste dressing in chronic venous leg ulcer patients and to compare the mean reduction in ulcer area at the end of 4 weeks.
Twenty patients with chronic venous leg ulcers were randomly divided into two groups. Group 1: Patients received PRF dressing which was repeated every week for 4 weeks. Group 2: Patients received Unna's paste dressing once a week for 4 weeks. The ulcer size was assessed with the help of photographs, and ulcer area was measured.
The mean reduction in the area of the ulcer size in the PRF group was 86.03% and in the Unna's paste group was 71.97%, which was not statistically significant with a value of 0.223.
We conclude that though there was no statistical significance between the groups, PRF showed a significant reduction in ulcer size.
下肢慢性静脉性溃疡难以治疗且复发常见。在各种治疗方式中,富血小板纤维蛋白(PRF)通过提供必要的生长因子,在溃疡愈合方面显示出了有前景的结果。尤纳氏糊剂敷料也已被证明可促进伤口愈合。
本研究的目的是比较自体PRF与尤纳氏糊剂敷料对下肢慢性静脉性溃疡患者的疗效,并比较4周结束时溃疡面积的平均缩小情况。
20例下肢慢性静脉性溃疡患者被随机分为两组。第1组:患者接受PRF敷料,每周重复一次,共4周。第2组:患者接受尤纳氏糊剂敷料,每周一次,共4周。借助照片评估溃疡大小,并测量溃疡面积。
PRF组溃疡大小面积的平均缩小率为86.03%,尤纳氏糊剂组为71.97%,P值为0.223,差异无统计学意义。
我们得出结论,尽管两组之间无统计学意义,但PRF显示出溃疡大小有显著缩小。
