探讨自制负压装置在糖尿病足患者"创面床准备"中的应用和优缺点。

回顾性分析2014年2月至2015年8月新疆维吾尔自治区人民医院烧伤、创面修复外科收治的60例糖尿病足患者的病例资料，其中30例患者采用自制负压封闭引流装置修复创面(治疗组)，30例患者采用山东威高新生医疗器械有限公司生产的封闭创伤负压引流装置(对照组)，比较两组患者的换药次数、治疗时间、疼痛程度评分、治疗费用及1周内创面肉芽覆盖面积等。计量资料比较采用t检验，等级资料比较采用秩和检验。

两组患者住院期间无死亡，无严重并发症出现。出院后随访3～7个月，中位随访时间为5个月。治疗组疼痛程度评分[(4.82±1.35)分]与对照组[(4.01±2.07)分]比较，差异无统计学意义(t＝1.194，P＝0.142)；但换药次数、治疗时间的比较中，对照组[(5.06±4.69)次、(19.54±28.97) d]少于治疗组[(10.22±7.32)次、(24.01±23.11) d]，差异均有统计学意义(t＝4.238、3.783，P＝0.024、0.048)；治疗费用的比较中，治疗组[(2.58±1.19)万元]明显低于对照组[(4.33±2.78)万元]，差异有统计学意义(t＝5.482，P＝0.017)。两组患者1周内肉芽覆盖面积的比较差异无统计学意义(Z＝0.345，P＝0.730)。

自制负压封闭引流装置相较于正规厂家生产的封闭创伤负压引流装置在糖尿病足患者"创面床准备"方面，在保证基本相同疗效的前提下能大大减少患者住院费用，适合基层医院应用推广。

To explore the application, advantages and disadvantages of self made simple negative pressure device in the preparation of wound bed for diabetic foot.

Statistical analysis 60 patients of diabetic foot in burns, wound repair surgery, People′s hospital of Xinjiang uygur autonomous region from February 2014 to August 2015, 30 patients underwent self made simple negative pressure device(treatment group), and 30 patients underwent the vacuum sealing drainage of Shandong wei gao xinsheng medical instrument co., LTD (control group). To compare the two groups of patients with times of dressing change, treatment time, pain degree, treatment cost and the area of wound granulation in a week and so on. Measurement data was analyzed with t test, grade data with rank sum test.

There was no perioperative deaths and serious complications duration of hospital stay in this two groups. After discharge, the patients were followed up for 3 to 7 months, with a median of 5 months.The difference was not statistically significant in pain degree [(4.82±1.35) points vs (4.01±2.07) points, t=1.194, P=0.142]. But times of dressing change and treatment time of control group were better than treatment group [times of dressing change(10.22±7.32) times vs (5.06±4.69) times, t=4.238, P=0.024; treatment time (24.01±23.11) d vs (19.54±28.97) d, t=3.783, P=0.048]. The treatment cost of treatment group was better than control group [(2.58±1.19) ten thousand yuan vs (4.33±2.78) ten thousand yuan, t=5.482, P=0.017]. The difference was not statistically significant in the area of wound granulation in a week(Z=0.345, P=0.730).

Self made negative pressure drainage device in the production of negative pressure drainage device in patients with diabetic foot wound bed preparation, in the premise of ensuring the same efficacy can greatly reduce the cost of hospitalization, suitable for primary hospital application promotion.
