PRP联合新型敷料在治疗慢性伤口中的应用效果观察

目的研究富血小板血浆(PRP)联合新型敷料在治疗慢性伤口中的应用效果。方法选取我院慢性伤口患者67例,按入院顺序分为2组。对照组(33例)采取传统敷料干预,观察组(34例)采取PRP联合新型敷料干预。比较2组的疗效。结果观察组伤口愈合时间短于对照组;干预1周、2周、4周、6周后VAS评分低于对照组;护理效果满意度高于对照组。以上差异均有统计学意义(P0.05)。结论 PRP联合新型敷料应用于治疗慢性伤口,可减轻疼痛程度,缩短伤口愈合时间,提高护理效果满意度。     

不同敷料组合对烧伤患者供皮区创面微环境的影响

目的 了解不同敷料组合对烧伤创面微环境及愈合的影响.方法 选择烧伤后需行手术植皮的患者186例,供皮区创面取皮厚度均为0.3 mm.将200个供皮区创面按表格随机法进行分组,分为藻酸盐棉垫组(藻酸盐敷料+棉垫)、凡士林棉垫组(凡士林油纱+棉垫)、藻酸盐泡沫组(藻酸盐敷料+泡沫敷料)、凡士林泡沫组(凡七林油纱+泡沫敷料).观察各种敷料对患者创面水分蒸发量及pH值的影响,比较各组创面的细菌定植情况、揭除敷料时患者疼痛程度及创面愈合时间.结果 共有184例患者的198个创面完成试验全过程,4种组合敷料可造成不同的创面微环境.藻酸盐棉垫组、凡士林棉垫组、藻酸盐泡沫组、凡士林泡沫组患者创面的敷料表面水分蒸发量分别为(35.5±3.2)、(31.3±2.8)、(23.1±2.9)、(18.1±2.3)mL·h-1·m-2,保湿性能以凡士林泡沫组为佳;创面pH值分别为7.22±0.06、7.41±0.03、7.05±0.03、7.34±0.06.创面细菌培养阳性率以藻酸盐泡沫组(4.0%)最低,凡士林泡沫组(22.4%)最高.揭除患者创面敷料时疼痛程度以藻酸盐泡沫组最轻(0.98±0.12),凡士林棉垫组最重(8.14±0.82).创面愈合时间藻酸盐泡沫组最短,为(6.7±0.8)d;凡士林泡沫组最长,为(15.6±3.5)d.结论 不同敷料在同样创面上使用,会营造不同的创面微环境;该环境与创面愈合时间密切相关,湿度对创面愈合的影响比pH值更为重要.     

碳纤维敷料在烧伤创面中的临床应用

目的观察碳纤维敷料对烧伤创面的治疗作用。方法选择浅Ⅱ°、深Ⅱ°和残余创面共277例,随机分为对照组(碘伏纱布换药)和治疗组(碳纤维敷料换药)。观察敷料吸收容量、创面炎症反应,并做创面细菌定量和创面组织学检查,记录创面愈合时间等。结果与对照组相比,治疗组敷料吸收容量大,创面炎症反应轻,创周炎症消退快,痂下组织细菌定量低。浅Ⅱ°、深Ⅱ°及残余创面愈合时间分别为(7．4±2．1)d、(16．2±2．6)d、(19．4±6．2)d,均较对照组缩短,对照组分别为(9．6±2．4)d、(19．6±3．4)d和(28．8±10．4)d。结论碳纤维敷料是一种具有吸附能力强、可有效控制炎症反应、促进创面愈合等特点的新型敷料。

不同敷料组合对烧伤患者供皮区创面微环境的影响

Objective To investigate the effect of dressing materials in various combinations on bum wound microenvironment and healing condition. Methods Two hundred donor sites with wounds of 0.3 mm in depth in 186 burn patients, who needed skingrafting and admitted to our ward were enrolled in study, and they were divided into A ( with dressing composed of aiginate + cotton pad for donor area), B ( with dressing composed of vaseline gauze + cotton pad for donor area) , C (with dressing composed of algi-nate+ foam dressing for donor area), D ( with dressing composed of vaseline gauze + foam dressing for donor area) groups according to random table method. Effect of dressings on wound evaporation and pH value were observed. Bacterial colonization, degree of pain complained by patients after dressing change, and wound healing time in each group were compared. Results One hundred and eighty-four patients complied with the study, while 2 patients were excluded due to untimely falling-off of the dressing. Wound evaporaton in respectively, among them B group showed optimal effect of keeping humidity (P<0.01). Wound pH value in A, B, C, D groups was 7.22±0.06, 7.41±0.03, 7.05±0.03, 7.34±0.06, respectively, among them it was highest in B group. The positive rate of bacteria in D group was highest (22.4%), and lowest in C group (4.0%). Pain was lightest in C group (score was 0.98±0.12), and most serious in B group ( score was 8.14±0.82). The shortest wound healing time was seen in C group (6.7±0.8 d) , and longest in D group (15.6±3.5 d). Conclusions Application of various dressings on similar wounds can pro-duce different wound microenvironment, which is closely related to wound healing time. Compared with pH value, humidity is the more important factor for wound healing.

透明型明胶/壳聚糖烧伤创面敷料的研制

研制烧(创)伤后创面的覆盖敷料，需找到一种载药性好、可生物降解、副作用小、应用面广的载体材料。明胶／壳聚糖凝胶则符合以上要求，且可根据不同目的制成凝胶或凝胶样膜使用。笔者通过对明胶／壳聚糖柔韧性和吸胀性的研究，探讨其作为创面敷料的可行性。
