双向牵引皮肤减张技术治疗胸腔引流管处愈合不良的疗效观察

Effect of bidirectional traction skin tension reduction technique in treatment of patients with poor healing at position of thoracic drainage tube

目的探讨双向牵引皮肤减张技术治疗胸腔引流管处愈合不良的疗效。方法将100例肺癌胸腔镜术后胸腔引流管处愈合不良患者随机分为观察组和对照组,每组50例。在伤口床准备后,对照组采用传统换药方法直至伤口愈合,观察组采用双向牵引皮肤减张技术闭合伤口。比较2组患者伤口愈合时间、换药次数、伤口愈合质量和伤口护理满意率。结果观察组患者伤口愈合时间、换药次数短于或少于对照组,差异有统计学意义(P<0.05)。伤口愈合3个月时,观察组温哥华瘢痕量表各项评分及总分均低于对照组,差异有统计学意义(P<0.05)。观察组患者伤口愈合总满意率为94.00%,高于对照组的72.00%,差异有统计学意义(P<0.05)。结论在肺癌胸腔镜术后胸腔引流处愈合不良的治疗中,运用双向牵引皮肤减张技术能促进伤口愈合,缩短伤口愈合时间,提高伤口愈合质量,减少瘢痕增生,提高患者对伤口护理的满意度。

Objective To explore the effect of bidirectional traction skin tension reduction technique in the treatment of patients with poor healing at position of thoracic drainage tube.Methods A total of 100 patients with poor healing at thoracic drainage tube after thoracoscopic surgery for lung cancer were randomly divided into observation group and control group,with 50 cases in each group.After preparing the wound bed,the control group was treated with traditional dressing change until wound healing,while the observation group was treated with bidirectional traction skin tension reduction technique to close the wound.The wound healing time,the number of dressing change,wound healing quality and satisfaction degree of wound nursing were compared between the two groups.Results Wound healing time and the number of dressing change in the observation group were significantly shorter and less than those in the control group(P<0.05).At 3 months of wound healing,the score of each item and total score of the Vancouver Scar Scale in the observation group were significantly lower than those in the control group(P<0.05).The total satisfaction rate of wound healing in the observation group was 94.00%,which was significantly higher than 72.00%in the control group(P<0.05).Conclusion In the treatment of patients with poor healing at thoracic drainage tube after thoracoscopic surgery for lung cancer,the application of bidirectional traction skin tension reduction technology can promote wound healing,shorten wound healing time,improve wound healing quality,reduce scar hyperplasia,and increase patients′satisfaction degree to wound nursing.
