持续负压引流技术对老年慢性难愈性创面的疗效观察

Effective observation of continued negative pressure drainage in the treatment of chronical wound in the aged people

目的观察持续负压引流技术治疗老年慢性难愈性创面的临床效果。方法选2005-12～2009-7入住本科的60岁以上慢性难愈性创面患者共38例,随机分为负压治疗组及常规治疗组,负压治疗组采用清创后装置持续负压引流装置,以负压值200～400mmHg压力持续负压吸引,炎症消退肉芽充填后植皮修复创面。常规治疗组采用保守换药、清创植皮、皮瓣等方法修复创面。结果负压治疗组在治疗时间、换药次数、治疗费用上均明显低于常规治疗组(P<0.05)。结论与常规治疗组相比,持续负压引流技术的应用能明显缩短慢性难愈性创面的愈合时间,减少换药次数及治疗费用,效果显著。

Objective To observe the clinical effect of continued negative pressure drainage in treating chronic wound in the aged people. Methods Thirty-eight patients over 60 years old suffered from the above wound and hospitalized into our section from December 2005 to July 2009 were divided into negative pressure treatment group （ Ⅰ group） and normal treatment group（ Ⅱ group） at random. In Ⅰ group,the device of continued negative pressure drainage was used after clearing the wound to drain at the negative pressure of 200 to 400 mmHg. As soon as the inflammation faded away and new issues grew up, it was necessary to recover the wound by making skin grafts. In the Ⅱ group, methods like conservative changing medicine, clearing wound and skin graft as well as skin flap were used to recover the wound. Results The Ⅱ group was obviously lower than the Ⅱ group in treatment period,times of changing medicine and treatment expense （ P 〈 0. 05 ）. Conclusion In comparison with the Ⅱ group, the application of the continued negative pressure drainge may obviously shorten the healing period of chronic wound, decrease times of changing medicine and treatment expense with evident effect.
