Mechanical debridement can be considered as an alternative to surgical debridement if surgery is not available, or is considered impractical or too high risk. One form of selective mechanical debridement is ultrasonic-assisted wound (UAW) debridement. As the published evidence on this is limited, a closed international expert meeting was held to review the existing evidence base on it, present preliminary findings of research currently in progress and discuss individual cases selected from the clinical experts' own practice. The panel also explored the potential barriers to the implementation of UAW debridement and how these might be addressed. It concluded there is sufficient evidence that UAW debridement is an effective method of cleansing and debriding almost all hard-to-heal wounds. Patients who are most likely to benefit from it are not medically stable, on anticoagulants, unable to visit a hospital for wound treatment, and/or have wounds with a poor vascular supply or are close to critical structures. The panel also observed that UAW debridement can be used to prepare the wound for negative pressure wound therapy (NPWT) or as an adjunctive to it. Given the potential to experience pain during the procedure, the panel considered that patients will benefit from topical analgesia. The panel noted that health professionals, patients and visitors must be protected from the aerosolisation associated with UAW, to reduce risk of cross-contamination.
如果无法进行手术,或者认为手术不切实际或风险过高,机械清创可被视为手术清创的替代方法。选择性机械清创的一种形式是超声辅助伤口(UAW)清创。由于关于此方法的已发表证据有限,因此召开了一次闭门国际专家会议,以审查其现有证据基础,介绍当前正在进行的研究的初步结果,并讨论从临床专家自身实践中选取的个别案例。该小组还探讨了实施UAW清创的潜在障碍以及如何解决这些障碍。会议得出结论,有足够的证据表明UAW清创是清洁和清创几乎所有难愈合伤口的有效方法。最有可能从中受益的患者是病情不稳定、正在服用抗凝剂、无法前往医院进行伤口治疗,和/或伤口血供不良或靠近关键结构的患者。该小组还观察到,UAW清创可用于为负压伤口治疗(NPWT)准备伤口或作为其辅助手段。鉴于该过程中可能会出现疼痛,该小组认为患者将受益于局部镇痛。该小组指出,必须保护医护人员、患者和访客免受与UAW相关的气溶胶影响,以降低交叉污染风险。
