Venous leg ulcer is a chronic condition, and various treatment modalities are available. Platelet-rich fibrin (PRF) is one of the newer modalities and it contains fibroblast growth factor (GF), vascular endothelial GF, angiopoitin and platelet-derived GF which enhances the wound healing. Hence, we conducted a randomised controlled trial to compare the efficacy of PRF versus saline dressing in chronic venous leg ulcers.
This study aims to compare the efficacy of autologous PRF with saline dressing in patients with chronic venous leg ulcer and to compare the mean reduction in ulcer area at the end of 4 weeks.
Fifteen patients with chronic venous leg ulcers of >6 months duration having an ulcer area of 1 cm × 1 cm to 5 cm × 5 cm were taken into the study and were randomly divided into two groups. Group 1: Patients received PRF dressing. Ten millilitres of patient's blood was taken and centrifuged at 3000 rpm for 15 min. A fibrin clot obtained in the middle of the tube was removed and used for dressing over the wound surface. It was repeated every week for 4 weeks. Group 2: Patients received saline dressings once a week for 4 weeks. The assessment of the ulcer size was done with the help of photographs, and ulcer area was measured.
The mean reduction in the area of the ulcer size in PRF group was 85.51%, and the mean reduction in the area of the ulcer size in Saline group was 42.74% which was statistically significant with a < 0.001 and = 4.11.
We conclude that PRF dressing can be used as it is effective, inexpensive, safe and an outpatient procedure.
下肢静脉溃疡是一种慢性疾病,有多种治疗方式。富血小板纤维蛋白(PRF)是较新的治疗方式之一,它含有成纤维细胞生长因子(GF)、血管内皮生长因子、血管生成素和血小板衍生生长因子,可促进伤口愈合。因此,我们进行了一项随机对照试验,以比较PRF与生理盐水敷料治疗慢性下肢静脉溃疡的疗效。
本研究旨在比较自体PRF与生理盐水敷料治疗慢性下肢静脉溃疡患者的疗效,并比较4周结束时溃疡面积的平均减少量。
选取15例病程超过6个月、溃疡面积为1cm×1cm至5cm×5cm的慢性下肢静脉溃疡患者纳入研究,并随机分为两组。第1组:患者接受PRF敷料治疗。采集患者10毫升血液,以3000转/分钟的转速离心15分钟。取出试管中部获得的纤维蛋白凝块,用于伤口表面的敷料。每周重复一次,共4周。第2组:患者每周接受一次生理盐水敷料治疗,共4周。借助照片评估溃疡大小,并测量溃疡面积。
PRF组溃疡面积的平均减少率为85.51%,生理盐水组溃疡面积的平均减少率为42.74%,差异具有统计学意义(P<0.001,t=4.11)。
我们得出结论,PRF敷料因其有效、廉价、安全且为门诊治疗方法而可被采用。
