摘要:

目的 分析局部氧疗联合重组牛碱性成纤维细胞生长因子(rb⁃bFGF)合并负压引流技术 (VSD)在慢性难愈性创面的作用。方法 选取 2020 10 月至 2021 10 月蚌埠医学院第一附属医院整 形烧伤科收治的 40 例慢性难愈性创面患者,随机分为对照组和观察组。对照组清创扩创后予以封闭式 负压引流(VSD)联合生理盐水治疗,观察组在对照组的基础上采用创面局部氧疗并联合 rb⁃bFGF 溶液灌 洗治疗。对比两组患者住院时间及费用、临床疗效、NRS 疼痛评分,取术前、术后 7 d 创面组织 HE 染色观 察组织病理学变化情况(创面炎性细胞变化),取术前、术后 714 d 创面组织进行免疫组化染色检测 VEGF HIF⁃1α 表达情况。结果 与对照组相比,观察组住院时间明显缩短,住院费用减少较明显,疼痛 减轻也较明显,差异有统计学意义(P < 0.05);与对照组相比,观察组治疗总有效率较高,差异有统计学意 义(P < 0.05);与对照组相比,观察组创面组织 HE 染色炎性细胞明显减少,差异有统计学意义(P < 0.05); 与对照组相比,观察组创面组织 VEGF HIF⁃1α 免疫组化染色提示,VEGF 表达量明显增高,HIF⁃1α 表 达量减少,差异均有统计学意义(P < 0.05)。结论1)局部氧疗联合 rb⁃bFGF 合并 VSD 治疗,治疗效果 明显优于 VSD 联合生理盐水冲洗治疗;(2)局部氧疗联合 rb⁃bFGF 合并 VSD 治疗,可明显改善创面状态, 降低 HIF⁃1α 表达量,提高 VEGF 表达量,改善创面微循环,加速创面愈合,缩短患者住院时间,减轻患者经 济负担。

Abstract:

Objective To analyze the effect of local oxygen therapy combined with recombinant bovine basic fibroblast growth factor(rb ⁃ bFGF)and negative pressure drainage(VSD)on chronic refractory wounds. Methods From October 2020 to October 2021,40 patients with chronic refractory wounds who were admitted to the Department of Plastic and Burn Surgery,The First Affiliated Hospital of Bengbu Medical College,were selected and randomly divided into control group and experimental group. The control group was treated with debridement and then with closed negative pressure drainage(VSD)combined with normal saline,while the experimental group was treated with local oxygen therapy combined with rb⁃bFGF lavage on the basis of the control group. The hospital⁃ ization time and cost,clinical efficacy,and NRS pain score were compared between the two groups,and the wound tissues were collected before operation,7 days after the operation to observe the histopathological changes (the number of inflammatory cells in the wound),and immunohistochemical staining of VEGF and HIF⁃1α expres⁃ sion. Results Compared with the control group,the experimental group had significantly shorter hospitalization time,lower hospitalization expenses,and less pain,and the differences were statistically significant(P < 0.05). Compared with that in the control group,the number of inflammatory cells in the wound tissue of the experimental group was significantly reduced,showing statistical significance(P < 0.05). The immunohistochemical staining of VEGF and HIF⁃1α in the wound tissue in the experimental group showed that the expression of VEGF was signifi⁃ cantly increased,but that of HIF⁃1α was decreased,and the differences were statistically significant(P < 0.05). Conclusion The therapeutic effect of local oxygen therapy combined with rb⁃bFGF and VSD is significantly betterthan that of VSD combined with saline irrigation. Local oxygen therapy combined with rb⁃bFGF and VSD can signif⁃ icantly reduce HIF⁃1α,increase the expression of VEGF,and improve the microcirculation of the wound and the healing of the wound. It also helps to shorten hospital stay,and reduce the economic burden of the patients.
