Chronic wounds are painful and debilitating to patients, pose a clinical challenge to physicians, and impose financial burden on the health-care system. New treatment options are therefore highly sought after. Ultrasound debridement is a promising technology that functions to disperse bacterial biofilms and stimulate wound healing. In this review, we focus on low-frequency ultrasound (20-60 kHz) and summarize the findings of 25 recent studies examining ultrasound efficacy. Ultrasound debridement appears to be most effective when used 3 times a week and has the potential to decrease exudate and slough, decrease patient pain, disperse biofilms, and increase healing in wounds of various etiology. Although current studies are generally of smaller size, the results are promising and we recommend the testing of low-frequency ultrasound therapy in clinical practice on a larger scale.
慢性伤口会给患者带来疼痛和功能障碍，给医生带来临床挑战，并给医疗保健系统造成经济负担。因此，人们迫切需要新的治疗方法。超声清创术是一项很有前景的技术，其作用是分散细菌生物膜并促进伤口愈合。在本综述中，我们聚焦于低频超声（20 - 60千赫），并总结了最近25项研究超声疗效的研究结果。超声清创术每周使用3次时似乎最为有效，并且有可能减少渗出物和腐肉，减轻患者疼痛，分散生物膜，并促进各种病因伤口的愈合。尽管目前的研究规模普遍较小，但结果很有前景，我们建议在临床实践中更大规模地测试低频超声治疗。
