The medical-surgical treatment of the difficult wounds represents a socio-sanitary problem in continuous growth, currently involving in our Country around 2,000,000 people. The "difficult wound" is a loss of cutaneous substances, usually due to multifactorial pathogenesis, that do not spontaneously lead to a complete recovery. Numerous studies in the literature have evidenced that the use of the advanced wound dressings allows to reach the best clinical and economic results in the process of recovery of the difficult wounds. The advanced would dressing assures a longer period of permanence on the injury and shorten the time of treatment and, as a consequence, it is required a smaller number of applications in comparison with the traditional medications. The Wound Bed Preparation (WBP) can be defined as the global and coordinate management of the cutaneous injury, enabling to chip off the local barriers to the recovery, or promoting the effectiveness of the innovative therapeutic instruments. The term advanced wound dressing indicates the dressing material having biocompatibility characteristics. The purpose of the advanced wound dressings is the one to create the ideal environment for the cicatrization process and isolate the wound from traumas and external infections.
The "Difficult Wounds" Unit of the Department of Plastic and Reconstructive Surgery of the Policlinico Umberto I in Rome, from January to December 2006, treated 570 patients (308 men and 262 women), whose age was between 2 days and 85 years, affected by ulcers of various nature. Among our cases, 200 patients were selected and randomly separated in two different groups: group A consisting of 100 patients entirely treated with traditional medications; group B composed by 100 patients treated with advanced dressings. Every patient has locally been treated with periodic and specific medications, according to the type of difficult wound, and subsequently they proceeded to find out how to treat the systemic factors causing ulcer. The patients underwent 3 times a week to medications in those cases presenting infection signs and 2 times a week in those cases where no infection signs were shown, for period varying from 1 month up to one year for the chronic forms.
The results showed a higher percentage of recovery reached by using the advanced dressings. Group A showed the followings results: the 53% of patients recovered from wounds; the remaining 47% patients did'nt not recover but in 17% cases medications showed to be of some help in the preparation of the vascular bed for the execution of a definitive operation (application of grafts or local edges), while the remaining 30% has shown a scarce improvement of the injury and they are still under treatment. Group B showed the 65% of patients recovered from wounds; as for the remaining 35% not recovered patients, medications represented an auxiliary aid to the preparation of the vascular bed for the execution of a definitive operation (application of grafts or local edges) for the 15% of patients, while the remaining 20%, even if not completely recovered, showed a notable improvement of the injury (reduction of the dimensions and disappearance of the infection and improvement of the patient quality of life).
In synthesis, it emerges that the advanced dressings, if correctly used, offer advantages in terms of clinical effectiveness (rapid recovery from the injury), patient quality of the life and cheapness. It has also to be considered that the difficult wound is often the epiphenomenon of a systemic illness. The difficult wound requires, therefore, a multidisciplinary treatment.
难愈伤口的外科治疗是一个日益严重的社会卫生问题,目前在我国约有200万人受其影响。“难愈伤口”是一种皮肤组织缺损,通常由多因素致病机制引起,不会自发完全愈合。文献中的大量研究表明,使用先进伤口敷料能在难愈伤口的愈合过程中取得最佳临床和经济效果。先进伤口敷料能确保在伤口上停留更长时间,缩短治疗时间,因此与传统药物相比,所需的换药次数更少。伤口床准备(WBP)可定义为对皮肤损伤的全面协调管理,能够消除局部愈合障碍,或提高创新治疗手段的有效性。先进伤口敷料这一术语指具有生物相容性特征的敷料材料。先进伤口敷料的目的是为愈合过程创造理想环境,使伤口免受创伤和外部感染。
罗马翁贝托一世综合医院整形与重建外科的“难愈伤口”科室在2006年1月至12月期间治疗了570例患者(308例男性和262例女性),年龄在2天至85岁之间,患有各种类型的溃疡。在我们的病例中,选择了200例患者并随机分为两组:A组由100例完全采用传统药物治疗的患者组成;B组由100例采用先进敷料治疗的患者组成。根据难愈伤口的类型,每位患者局部接受定期和特定药物治疗,随后针对导致溃疡的全身因素进行治疗。出现感染迹象的患者每周接受3次药物治疗,未出现感染迹象的患者每周接受2次药物治疗,慢性伤口的治疗时间为1个月至1年。
结果显示,使用先进敷料的伤口愈合率更高。A组的结果如下:53%的患者伤口愈合;其余47%的患者未愈合,但在17%的病例中,药物治疗在为最终手术(移植或局部边缘手术)准备血管床方面有一定帮助,而其余30%的患者伤口改善甚微,仍在接受治疗。B组有65%的患者伤口愈合;对于其余35%未愈合的患者,药物治疗对15%的患者在为最终手术(移植或局部边缘手术)准备血管床方面起到辅助作用,而其余患者(20%)即使未完全愈合,伤口也有明显改善(尺寸减小、感染消失、患者生活质量提高)。
综合来看,先进敷料如果正确使用,在临床疗效(伤口快速愈合)、患者生活质量和成本方面具有优势。还应考虑到,难愈伤口往往是全身性疾病的外在表现。因此,难愈伤口需要多学科治疗。
