自制负压引流装置不同负压值对创面愈合效果的影响观察

Effect of Appropriate Negative Pressure on Wound Healing by Self-made Negative Pressure Drainage Device

目的:观察自制负压引流装置治疗皮肤创面时不同负压值对愈合效果的影响。方法:选择2014年10月-2016年9月的慢性溃疡型皮肤创面和外伤型皮肤创面患者100例,两种类型皮肤创面患者根据随机数字表法随机分为高负压值组(-201mm Hg^-300mm Hg)和低负压值组(-100mm Hg^-200mm Hg),清创后应用自制负压引流装置行负压引流治疗,治疗期间每天采集1次负压值,直到创面愈合,记录创面愈合时间。结果:慢性溃疡型皮肤创面患者低负压值组创面愈合时间为(23.55±12.70)d,高负压值组愈合时间为(38.19±23.69)d,差异有统计学意义(P<0.05);外伤型皮肤创面患者低负压值组创面愈合时间为(26.83±9.48)d,高负压值组愈合时间为(37.35±14.75)d,差异有统计学意义(P<0.05)。结论:使用自制负压引流装置治疗慢性溃疡型、外伤型皮肤创面,选择-100mm Hg^-200mm Hg的低负压值能更有效地促进创面愈合。

Objective To observe the effect of different negative pressure value on skin wounds healing when treated with self-made negative pressure drainage device. Methods 100 cases of chronic ulcerative skin wounds and traumatic skin wounds patients were selected from October 2014 to September 2016. Two types of skin wound patients were randomly divided into two groups： high negative pressure group （-201mmHg - -300mmHg） and low negative pressure group （-100mmHg- -200mmHg）. After debridement treatment, the patients were treated with negative pressure drainage by self-made negative pressure drainage device. The negative pressure was collected every day during treatment until the wound healed ,the healing time was recorded too. Results In the patients with chronic ulcerative skin, the healing time of the low negative pressure group was （23.55±12.70）d, and the healing time of the high negative pressure group was （38.19±23.69）d, the difference was statistically signifcant （P〈0.05）. In the patients with traumatic skin wounds, the healing time of the low negative pressure group was （26.83±9.48）d, and the healing time of the high negative pressure group was （37.35±14.75）d, the difference was statistically signifcant （P〈0.05）. Conclusion The low negative pressure value of -100mmHg - -200mmHg can be more effectively promote the healing of wound surface by using a self-controlled negative pressure drainage device to treat chronic ulcer type and traumatic skin wound.
