An increasing number of compression systems available for treatment of venous leg ulcers and limited evidence on the relative effectiveness of these systems are available. The purpose of this study was to conduct a randomised controlled trial to compare the effectiveness of a four-layer compression bandage system and Class 3 compression hosiery on healing and quality of life (QL) in patients with venous leg ulcers. Data were collected from 103 participants on demographics, health, ulcer status, treatments, pain, depression and QL for 24 weeks. After 24 weeks, 86% of the four-layer bandage group and 77% of the hosiery group were healed (P = 0·24). Median time to healing for the bandage group was 10 weeks, in comparison with 14 weeks for the hosiery group (P = 0·018). The Cox proportional hazards regression found participants in the four-layer system were 2·1 times (95% CI 1·2-3·5) more likely to heal than those in hosiery, while longer ulcer duration, larger ulcer area and higher depression scores significantly delayed healing. No differences between groups were found in QL or pain measures. Findings indicate that these systems were equally effective in healing patients by 24 weeks; however, a four-layer system may produce a more rapid response.
目前有越来越多的压缩系统可用于治疗静脉性腿部溃疡,但关于这些系统的相对有效性的证据有限。本研究旨在开展一项随机对照试验,比较四层加压绷带系统和 3 级压力弹力袜对静脉性腿部溃疡患者的愈合效果和生活质量(QOL)的影响。在 24 周的时间里,对 103 名参与者的人口统计学、健康状况、溃疡状况、治疗、疼痛、抑郁和 QOL 数据进行了收集。24 周后,4 层绷带组有 86%的患者和弹力袜组有 77%的患者实现了愈合(P=0.24)。绷带组的中位愈合时间为 10 周,而弹力袜组为 14 周(P=0.018)。Cox 比例风险回归分析发现,与弹力袜组相比,使用 4 层系统的患者愈合的可能性要高出 2.1 倍(95%CI 1.2-3.5),而溃疡持续时间较长、溃疡面积较大和抑郁评分较高则显著延迟了愈合。两组在 QOL 或疼痛测量方面没有差异。研究结果表明,这两种系统在 24 周内对患者的愈合效果相当;然而,4 层系统可能会产生更快的反应。
