目的 探究褥疮创面修复中,负压封闭引流技术（VSD）结合臀大肌带蒂肌皮瓣对促进患者愈合的效果。方法 纳入2020年6月—2023年3月入院的60例骶尾部褥疮合并皮肤软组织缺损患者作为研究对象,按照不同治疗方案分为常规组（n=30）和研究组（n=30）,常规组接受臀大肌上部肌皮瓣修复治疗,研究组接受VSD结合臀大肌带蒂肌皮瓣治疗。观察两组患者创面愈合情况、术后感染发生情况、创面愈合时间、换药次数、抗菌药物使用时间和住院时间。结果 研究组甲级愈合率高于常规组;与常规组比较,研究组换药次数少,愈合时间、抗菌药物应用时间与住院时间更短,差异有统计学意义（P<0.05）。结论 褥疮创面修复中,VSD结合臀大肌带蒂肌皮瓣手术能够提高愈合质量,加快创面恢复,值得临床推广和应用。

Objective To explore the effect of vacuum sealing drainage combined with gluteus maximus pedicled myocutaneous flap on promoting the healing of bedsore wounds in patients. Methods A total of 60 cases of sacrococcygeal bedsore and skin and soft tissue defects were recruited in the study from June 2020 to March 2023. They were divided into two groups according to different treatment schemes： routine group （n=30） and study group （n=30）. The routine group received repair treatment of the upper gluteus maximus myocutaneous flap， and the study group received VSD combined with gluteus maximus pedicled myocutaneous flap treatment. Wound healing， occurrence of postoperative infections， wound healing time， number of dressing changes， use time of antibiotics， and length of hospital stay were recored of the two groups. Results Compared with the routine group， the study group had a higher grade A healing rate， less dressing changes， and shorter healing time， use time of anitbiotics， and length of hospital stay （P<0.05）. Conclusion In the repair of bedsore wounds， VSD combined with pedicled myocutaneous flap of gluteus maximus can elevate healing quality， facilitate wound recovery， and is worthy of clinical promotion and application.
