自行研发封闭式负压引流联合海绵敷料治疗Ⅲ～Ⅳ期难愈性压疮的效果观察

目的探讨自行研发封闭式负压引流(vacuum assisted closure,VAC)联合海绵敷料治疗Ⅲ～Ⅳ期难愈性压疮效果。方法将60例Ⅲ～Ⅳ期压疮患者随机分为实验组和对照组,每组各30例。实验组采用自行研制的VAC装置联合海绵敷料治疗难愈性压疮,对照组采用传统敷料换药治疗。比较两组患者创面新鲜肉芽组织增生时间、填充创面时间、治愈时间及治疗费用情况。结果实验组患者创面新鲜肉芽组织增生与填充创面缺损时间、治愈时间明显短于对照组,治疗费用明显低于对照组,两组比较,差异具有统计学意义(均P<0.05)。结论使用自行研发封闭式负压引流联合海绵敷料换药治疗Ⅲ～Ⅳ期难愈性压疮,压疮创面新鲜肉芽组织增生、填充创面的时间快,有效缩短治愈时间,减轻患者的痛苦及经济负担,值得在基层医院推广应用。

Effect of self-designed closed negative pressure drainage combined with sponge dressing on refractory wounds

Objective To investigate the effect of self-designed closed negative pressure drainage combined with sponge dressings on refractory wounds.Methods Sixty patients with phase III-IV pressure ulcers were randomly divided into experiment group and control group in equal number.The self-designed closed negative pressure drainage combined with sponge dressing was applied in the experiment group and in the control group the conventional dressings were used.The two groups were compared in terms of hyperplasia of fresh granulation tissue,time for filling the defect and the healing time and the medical expense.Results Compared to the control group,the time for hyperplasia of fresh granulation tissue,the time for filling the defect and the healing time in the experiment group were all significantly shorter,and the medical expense of the experiment group was significantly less（all P 0.01）. Conclusion The self-designed closed negative pressure drainage combined with sponge dressings in the treatment of phase III-IV refractory pressure ulcers may effectively shorten the healing time,improve the curative effects and reduce the economic burden of patients.
