Negative pressure wound therapy is widely used in the treatment of hard-to-heal wounds; however, pain during dressing changes, which is often associated with pain on the commencement and cessation of pressure application and because of in-growth of new granulation tissue into interstices of foam dressings, is often experienced. Anecdotal reports have suggested that choice of gauze as the negative pressure wound therapy dressing may reduce the pain associated with dressing changes. A prospective, multi-center, non-comparative clinical investigation was carried out using gauze-based negative pressure wound therapy in chronic and acute wounds. Over 152 patients were evaluated. Median duration of therapy was 18 days with 91% of patients progressing towards healing at the end of therapy. Wound pain and odour were significantly reduced (P < 0.001) over the course of therapy. Wound pain during dressing changes was reported to be absent in 80% of dressing removals. No damage to the wound bed following dressing removal was observed in 96% of dressing changes. Dressing applications were considered easy in 79% of assessments and took a median of 20 min to complete. In patients susceptible to pain, gauze-based negative pressure therapy may be a viable option to maximise patient comfort.
负压伤口疗法被广泛应用于治疗难以愈合的伤口；然而，在更换敷料时会感到疼痛，这通常与开始和停止施加压力时的疼痛以及由于新肉芽组织长入泡沫敷料的间隙有关。有传闻称，选择纱布作为负压伤口疗法的敷料可能会减轻与敷料更换相关的疼痛。一项使用基于纱布的负压伤口疗法治疗慢性和急性伤口的前瞻性、多中心、非对照临床研究进行了评估。超过 152 名患者接受了评估。中位治疗时间为 18 天，91%的患者在治疗结束时朝着愈合方向进展。在治疗过程中，伤口疼痛和气味显著减轻（P<0.001）。80%的敷料去除时报告敷料更换时无伤口疼痛。96%的敷料更换时未观察到对伤口床的损伤。79%的评估认为敷料应用简单，完成时间中位数为 20 分钟。对于容易疼痛的患者，基于纱布的负压治疗可能是一种可行的选择，以最大限度地提高患者的舒适度。
