非愈合性溃疡难以管理,因为它们偏离正常的伤口愈合过程。使用盐水敷料的标准治疗在治疗具有此类伤口的患者中无效;需要高级伤口护理敷料。基于壳聚糖的高级伤口敷料因其独特的特性而越来越受欢迎,如吸收性,一致性,和减轻伤口的疼痛。介绍了一例在蜂窝织炎后发展并通过应用壳聚糖基敷料治愈的溃疡。
一名患有高血压的81岁女性因高烧入院,广义弱点,厌食症,右下肢疼痛伴发红。在彩色多普勒超声上明显可见右下肢静脉功能不全,表现为右股股和股动脉交界处的早期功能不全以及右腿静脉曲张。诊断为蜂窝织炎;患者接受抗生素治疗并出院。蜂窝织炎进展,第二次入院时进行右腿切开引流。病人又入院两次,伤口手术清创两次,并给予抗生素。在此期间,患者接受盐水换药治疗近4周.因为伤口在第四次住院期间未愈合并感染,使用基于壳聚糖的敷料。每日换药10天产生100%肉芽组织。稍后,患者接受了植皮手术,最终出院。
使用基于壳聚糖的敷料导致进展到完全造粒,随着渗出物的管理,疼痛,和假单胞菌感染。这种情况的结果表明,溃疡不愈合的患者可能会从早期使用高级伤口护理敷料中受益。
Nonhealing ulcers are difficult to manage because they deviate from the normal wound healing process. The standard treatment with saline dressings is not efficient in treating patients with such wounds; advanced wound care dressings are needed.
Chitosan-based advanced wound dressings are gaining popularity because of their unique characteristics, such as absorbency, conformability, and pain alleviation at the wound bed. A
case of an ulcer that developed after cellulitis and healed with application of a
chitosan-based dressing is presented.
An 81-year-old female with hypertension was admitted to the hospital with a high-grade fever, generalized weakness, anorexia, and right lower limb pain with redness. Venous insufficiency in the right lower limb in the form of early insufficiency at the right saphenofemoral and saphenopopliteal junctions along with right leg varicosities was evident on color Doppler ultrasound. A diagnosis of cellulitis was made; the patient was treated with antibiotics and discharged from the hospital. The cellulitis progressed, and an incision and drainage of the right leg was performed on the second admission. The patient was admitted twice more, and the wound was surgically debrided twice and antibiotics were administered. During this period, the patient was treated with saline dressing changes for almost 4 weeks. Because the wound was nonhealing and infected during the fourth hospital admission,
chitosan-based dressings were used. Daily dressing changes for 10 days resulted in 100% granulation tissue. Later, the patient underwent skin grafting and was eventually discharged.
The use of
chitosan-based dressings resulted in progression to complete granulation, along with the management of exudate, pain, and Pseudomonas infection. The results of this
case suggest patients with nonhealing ulcers may benefit from early use of advanced wound care dressings.
