摘　　要：目的:评估双通道真空密封引流(dual-channel vacuum sealing drainage,DC-VSD)相较于单通道技术(singlechannel vacuum sealing drainage,SC-VSD)在难愈性创面愈合中的临床效能,重点关注患者满意度、住院成本、住院时间及感染发生率。方法:2023年05月—2024年5月,选取汕头大学医学院第二附属医院80例难愈性创面患者,随机分为DC-VSD组和SC-VSD组,每组40例。采用压疮愈合评分(pressure ulcer scale for healing,PUSH)评估术后28 d内创面愈合情况,并收集患者满意度、住院费用、住院时间及感染率等数据。数据采用SPSS 23.0进行统计分析。结果:基线特征显示,两组患者基本人口统计数据、创面性质和合并症相似。PUSH评分显示,DC-VSD组与SC-VSD组之间存在显著差异(P<0.001),效应量中等至高。不同时间点PUSH评分变化显著(P<0.001),效应量高效;组别×时间交互作用显著(P=0.007),效应量中等,表明DC-VSD疗效随时间逐渐优于SC-VSD。此外,DC-VSD组患者满意度更高(P=0.02),住院费用更低(P=0.03),住院时间更短(P=0.005),感染发生率降低(P=0.04)。多因素分析结果一致。结论:双通道VSD技术在治疗难愈性创面方面表现出显著的临床优势,不仅提高创面愈合速度,还提升护理满意度,缩短住院时间,降低了细菌感染率,且未增加患者经济负担。Objective:To evaluate the clinical efficacy of dual-channel vacuum sealing drainage(DC-VSD)compared to single-channel vacuum sealing drainage(SC-VSD)in chronic wound healing,with a focus on patient satisfaction,hospitalization costs,length of stay,and infection rates.Methods:From May 2023 to May 2024,80 patients with refractory wounds were selected from the Second Affiliated Hospital of Shantou Medical University and randomly divided into DC-VSD and SC-VSD groups,with 40 patients in each group.The Pressure Ulcer Scale for Healing(PUSH)was used to assess wound healing within 28 days postoperatively,and data on patient satisfaction,hospitalization costs,length of stay,and infection rates were collected.Data were statistically analyzed using SPSS 23.0.Results:Baseline characteristics showed that the two groups were similar in terms of demographic statistics,wound nature,and comorbidities.The PUSH scores revealed significant differences between the DC-VSD and SC-VSD groups(P<0.001),with moderate to high effect sizes.Significant changes in PUSH scores were observed at different time points(P<0.001),with high effect sizes;the group-by-time interaction was also significant(P=0.007),with a moderate effect size,indicating that the efficacy of DC-VSD gradually surpassed SC-VSD over time.Additionally,patients in the DC-VSD group had higher satisfaction(P=0.02),lower hospitalization costs(P=0.03),shorter lengths of stay(P=0.005),and reduced infection rates(P=0.04).Multivariate analysis results were consistent.Conclusion:DC-VSD technology demonstrates significant clinical advantages in the treatment of refractory wounds,not only improving wound healing speed but also enhancing nursing satisfaction,shortening hospital stays,reducing bacterial infection rates,and not increasing the economic burden on patients.This study provides new evidence for the treatment of refractory wounds and supports the clinical value of DC-VSD technology.
