水胶体敷料对难愈性创面临床治疗的队列研究

Cohort study on hydrocolloid dressings for clinically treating refractory wound

目的观察水胶体敷料治疗难愈性创面的临床治疗效果。方法将该院2015年1月至2017年8月收治的532例难愈性创面患者随机分为对照组(266例)和试验组(266例),经常规处理后对照组采用无菌生理盐水纱布湿敷后无菌夹纱棉垫包扎,试验组采用水胶体敷料覆盖后用无菌夹纱棉垫包扎,每2~3d换药1次。观察创面新鲜肉芽生长时间、愈合率及炎性反应发生情况。结果试验组创面新生肉芽生长所需时间、愈合率、炎性反应发生率显著优于对照组,差异均有统计学意义(P<0.01)。结论无菌水胶体敷料有利于难愈性创面坏死组织的脱落,促进新鲜肉芽生长,能有效缩短创面愈合时间,值得在临床中推广应用。

Objective To observe the clinical effect of hydrocolloid dressing for treating refractory wounds. Methods A total of 532 patients with refractory wounds in this hospital from January 2015 to August 2017 were randomly divided into the control group （266 cases） and experimental group （266 cases）.The control group adopted the sterile cotton pad bandage after sterile saline gauze wet compressing,while the experimental group adopted sterile cotton pad bandage after hydrocolloid dressing covering,once dressing change every 2-3 d.The fresh granulation growth time of wound surface,healing rate and inflammatory reaction occurrence were observed. Results The required time for fresh granulation growth,healing rate and occurrence rate of inflammatory reaction in the experimental group were significantly better than those in the control group,and the difference between the two groups was statistically significant （ P 〈0.01）. Conclusion Sterile hydrocolloid dressing is conducive to the exfoliation of wound surface necrosis tissue,promotes the growth of fresh granulation,can effectively shorten the wound healing time,and is worth promotion in clinicx.
