摘要:

文题释义:
加速康复外科(enhanced recovery aftersurgery,ERAS):是指在围术期实施各种已证实有效的方法减少手术患者的应激及并发症,减少生理及心理创伤和应激,降低病死率及缩短住院时间,加快患者的康复速度。
碱性成纤维细胞生长因子:是一种多功能的多肽生长因子,在创面愈合3个阶段中均发挥着重要作用:在炎症期可对炎性细胞产生趋化作用,进而有利于清除伤口异物及坏死组织;在增生期能促进成纤维细胞和新生毛细管生长、促肉芽组织形成;在成熟期可促进损伤区域的神经纤维再生,以上作用均有利于组织修复和创面愈合。

背景:纳米银抗菌敷料和水凝胶是新型敷料,用于感染伤口的治疗。重组人碱性成纤维细胞生长因子是临床常应用于开放性伤口的活性多肽类药物。
目的:探究外用重组人碱性成纤维细胞生长因子、纳米银抗菌水凝胶敷料在踝部开放骨折清创术后创面愈合中的应用。
方法:收集踝部开放骨折清创术后患者99例,根据随机对照表分为对照组、试验A组和试验B组,每组33例。对照组创面敷以凡士林纱条及无菌纱布;试验组采取重组人碱性成纤维细胞生长因子喷涂于创面及周围,试验A组创面采用无菌纱布覆盖;试验B组创面予以纳米银抗菌水凝胶敷料覆盖,各组均每2 d换药1次。当患者符合下列任一情况时,皆终止研究项目的治疗措施:清创切口及皮损转归为符合择期手术皮肤及软组织条件时;明确为创面感染并需进一步进行再次清创、皮瓣移植、真空负压负压吸引等措施时。治疗结束后记录并统计对比分析3组患者血运恢复时间、创面愈合转归时间、关节肿胀评分、疼痛目测类比评分(VAS)、血清炎症因子、氧化应激指标(丙二醛、超氧化物歧化酶)及术后切口并发症发生率。研究经中国医科大学附属盛京医院医学伦理委员会批准,患者均签署知情同意书。
结果与结论:①与对照组相比,试验B组、试验A组临床总有效率、超氧化物歧化酶较高,关节肿胀评分、疼痛目测类比评分、白细胞介素6、C-反应蛋白、肿瘤坏死因子α、D-二聚体、丙二醛较低(P < 0.05);治疗后与试验A组相比,试验B组上述各项指标较低(P < 0.05),血运恢复时间、创面愈合转归时间缩短(P < 0.05);②与试验A组和对照组相比,试验B组术后切口并发症发生率较低,但差异无统计学意义   (P > 0.05);③结果说明,联合应用外用重组人碱性成纤维细胞生长因子、纳米银抗菌水凝胶敷料能减轻局部肿胀、缓解术后疼痛、促进踝部开放骨折创面恢复,缓解炎症反应及氧化应激反应,有效降低术后切口并发症发生率。

Abstract: BACKGROUND: Nano-silver antibacterial dressings and hydrogels are both new types of dressings used for the treatment of infected wounds. Recombinant human basic fibroblast growth factor is an active peptide drug commonly used for open wounds.
OBJECTIVE: To explore the application of topical recombinant human basic fibroblast growth factor and nano-silver antibacterial hydrogel dressing in wound healing of patients with open ankle fracture after debridement. 
METHODS: A total of 99 patients scheduled for debridement due to open ankle fracture were randomly divided into control group, test group A and test group B, with 33 patients in each group. Vaseline gauze and sterile gauze were applied in the control group. Test group A was treated with recombinant human basic fibroblast growth factor and wounds were covered with sterile gauze. Test group B was treated with recombinant human basic fibroblast growth factor, and wounds were covered with nano-silver antibacterial hydrogel dressing. Dressing in each group was changed every 2 days. The therapeutic measures related to the study should be terminated if one of the following conditions occurs: (1) after debridement, the incision and skin lesions are converted to meet the requirements of elective surgery with regard to skin and soft tissue; (2) wound infections are confirmed and requires further debridement, skin flap transplantation, vacuum negative pressure suction and other measures. After treatment, time of blood supply recovery, time of wound healing, joint swelling score, Visual Analogue Scale score, serum inflammatory factors, oxidative stress index (malondialdehyde, superoxide dismutase) and postoperative incision complications were compared and analyzed. The study protocol was approved by the Medical Ethics Committee of Shengjing Hospital Affiliated to China Medical University, and each patient signed an informed consent form.
RESULTS AND CONCLUSION: Compared with the control group, the total clinical response rate and superoxide dismutase level were significantly higher in the two test groups, and the joint swelling score, Visual Analogue Scale score, levels of interleukin-6, C-reactive protein, tumor necrosis factor-α, D-dimer, and malondialdehyde were significantly lower in the two test groups (P < 0.05). After treatment, the above-mentioned indexes were all lower in the test group B than the test group A (P < 0.05). The blood supply recovery time and wound healing time were also shorter in the test group B than the test group A (P < 0.05). Compared with the test group A and control group, the incidence of postoperative incision complications was lower in the test group B; however, there were no significant difference (P > 0.05). Findings of the present study reveal that topical application of human recombinant basic fibroblast growth factor combined with nano-silver antibacterial hydrogel dressings can relieve swelling and pain, promote wound healing, relieve inflammatory responses and oxidative stress, and effectively reduce postoperative incision complications.
