自制负压封闭引流装置在人工血管动静脉内瘘术后切口不愈合患者中的应用效果

Application Effect of Self-made Negative Pressure Closed Drainage Device in Patients with Non-healing Incision After Artificial Vascular Arteriovenous Fistula Surgery

目的:探讨自制负压封闭引流装置在人工血管动静脉内瘘(AVG)术后切口不愈合患者中的应用效果。方法:选取2019年1月—2021年12月广州医科大学附属第二医院收治的AVG术后切口不愈合患者24例作为研究对象,随机数字表法分为试验组和对照组,各12例。对照组给予碘伏涂抹与纱条填塞引流换药,试验组给予自制负压封闭引流装置,比较两组患者的切口愈合指标与疼痛程度。结果:试验组切口愈合时间短于对照组,换药次数少于对照组,差异有统计学意义(P<0.05);试验组疼痛评分低于对照组,差异有统计学意义(P<0.05)。结论:自制负压封闭引流装置在处理AVG术后切口不愈合中能加速切口愈合,减少换药次数,降低疼痛感,值得推广。

Objective:To explore the application effect of self-made negative pressure closed drainage device in the patients with non-healing incision after artificial vascular arteriovenous fistula(AVG)surgery.Methods:A total of 24 patients with non-healing incision after AVG surgery who were treated in the Second Affiliated Hospital of Guangzhou Medical University from January 2019 to December 2021 were selected as the study subjects.The subjects were divided into experimental group and control group by using random number table method,with 12 cases in each group.The control group was given iodophor application and gauze tamponade drainage and dressing change,and the experimental group was given a self-made negative pressure closed drainage device.The incision healing index and pain level of the two groups were compared.Results:The incision healing time in the experimental group was shorter than that in the control group,the number of dressing changes in the experimental group was lower than that in the control group,and the difference was statistically significant(P<0.05).The pain score in the experimental group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion:The self-made negative pressure closed drainage device can accelerate the healing of the incision,reduce the number of dressing changes,and reduce the pain in the treatment of non-healing incision after AVG surgery,which is worthy of promotion.
