自制便携式简易封闭负压引流装置在术后切口愈合不良中的应用

Application of a self- made portable simplified vacuum sealing drainage device in patients with poor surgical wound healing

目的探讨一种自制便携式简易封闭负压引流装置在手术后切口愈合不良中的应用效果。方法回顾性分析2015年1月至2018年10月在江苏省靖江市人民医院烧伤整形科进行术后切口愈合不良治疗的50例患者资料。其中,25例采用自制便携式简易封闭负压引流装置进行持续低负压吸引设为治疗组,25例采用碘伏纱条填塞引流换药,设为对照组。观察2组创面形态学变化;比较2组患者的切口愈合时间、换药次数、疼痛程度、换药材料费用指标。对数据行t检验。结果治疗组患者创面清洁,肉芽组织新鲜红润;对照组患者创面肉芽组织生长不佳,渗液较多。治疗组患者的切口愈合时间、换药次数、疼痛程度、换药材料费用分别为(14.7±4.3)d、(5.1±1.4)次、(5.9±1.4)分、(639.5±127.4)元,对照组患者对应的指标分别为(38.6±5.9)d、(49.2±9.7)次、(8.2±1.8)分、(1 357.5±135.9)元,2组对应指标比较,差异均有统计学意义(t=-16.3、-32.8、-4.9、-38.5,P值均小于0.05)。结论自制便携式简易封闭负压引流装置在术后切口愈合不良患者中,能显著缩短切口愈合时间,减少换药次数,减轻疼痛程度,换药材料费用明显减少,大大提高了手术切口治愈率,优于传统方法换药,具有一定的推广价值。

Objective To discuss the application effect of a self-made portable simplified vacuum sealing drainage device in patients with poor surgical wound healing.Methods Retrospective analysis was made on 50 patients with poor surgical wound healing,which were hospitalized from January 2015 to October 2018 in Department of Burns and Plastic Surgery,Jingjiang People′s Hospital.Among them,25 patients who used self-prepared portable simple-type were set as the treatment group,and 25 patients of continuous low negative pressure suction with iodine volv gauze packing and drainage were set as the control group.Morphological changes of wounds were observed in the two groups.The wound healing time,number of dressing changes,pain intensity,and cost of dressing changes were compared between the two groups.Data were processed with t test.Results In the treatment group,the wound surface was clean and the granulation tissue was fresh and rosy.In the control group,the growth of wound granulation tissue was not good and there was more effusion.The wound healing time,number of dressing changes,pain intensity,and cost of dressing changes of the treatment group were(14.7±4.3)d,(5.1±1.4)times,(5.9±1.4)points,(639.5±127.4)yuan,the corresponding indexes of the control group respectively were(38.6±5.9)d,(49.2±9.7)times,(8.2±1.8)points,(1 357.5±135.9)yuan,there were statistically significant differences in these corresponding indexes of patients between the two groups(t=-16.3,-32.8,-4.9,-38.5,with P values below 0.05).Conclusions This self-made portable simplified vacuum sealing drainage device can significantly reduce the wound healing time,number of dressing changes,pain intensity,and cost of dressing changes;greatly increase the healing rate of surgical wounds,better than the traditional method of dressing changes.Therefor,it is superior to the conventional dressing change and suitable for broader clinical use.
