Compression therapy is not common for venous leg ulcer patients in Hong Kong.
This randomized controlled trial compared the clinical effectiveness of compression bandaging using four-layer bandaging (4LB) or short-stretch bandaging (SSB) and usual care (moist wound healing dressing without compression). The 24-week study looked at venous leg ulcer patients aged >60 years in a community setting. The primary parameter was time to ulcer healing. Secondary parameters were ulcer area and pain reduction comparing week 0 (start) vs week 24 (end), measuring results per group and between groups. Intention-to-treat analysis involved descriptive statistics, survival analysis, and repeated measures analysis of variance. The log-rank test was used for univariable analysis. All withdrawn patients had a negative outcome score over the whole study duration.
Of 321 patients who received randomized treatment, 45 (14%) did not complete the 24-week study period. At 24 weeks, Kaplan-Meier analysis on healing time was statistically significant (P < .001) in favor of the compression groups. The mean (SD) healing time in the SSB group (9.9 [0.77]) was shorter than that of the 4LB group (10.4 [0.80]) and the usual care group (18.3 [0.86]). Pain reduction was significant (P < .001) for the compression-treated groups only.
Compression bandaging was more effective than usual care without compression. Both compression systems were safe and feasible for venous ulcer patients in a community setting in Hong Kong.
在香港,静脉性腿部溃疡患者并不常采用压迫疗法。
本随机对照试验比较了使用四层包扎(4LB)或短拉伸包扎(SSB)与常规护理(不使用压迫的湿性伤口愈合敷料)对静脉性腿部溃疡患者的临床效果。这项 24 周的研究观察了社区环境中年龄>60 岁的静脉性腿部溃疡患者。主要参数是溃疡愈合时间。次要参数是比较第 0 周(开始)和第 24 周(结束)时溃疡面积和疼痛减轻情况,对每组和组间的测量结果进行评估。意向治疗分析包括描述性统计、生存分析和重复测量方差分析。对数秩检验用于单变量分析。所有退出患者在整个研究期间的结果评分均为负面。
在接受随机治疗的 321 名患者中,有 45 名(14%)未完成 24 周的研究期。在 24 周时,愈合时间的 Kaplan-Meier 分析在统计学上具有显著性(P<.001),有利于压迫组。SSB 组的平均(SD)愈合时间(9.9[0.77])短于 4LB 组(10.4[0.80])和常规护理组(18.3[0.86])。仅在接受压迫治疗的组中,疼痛减轻具有统计学意义(P<.001)。
压迫包扎比不使用压迫的常规护理更有效。在香港社区环境中,两种压迫系统对静脉性溃疡患者均安全且可行。
