To observe the application effect of double-tube negative pressure drainage in the repair of refractory wounds.
From January 2020 to April 2023, 50 patients undergoing refractory wound repair in the Department of Burn and Plastic Surgery of Jingjiang People's Hospital, Jiangsu were selected. According to different treatment methods, they were divided into an observation group and a control group, with 25 patients in each group. The observation group was treated with double-tube negative pressure drainage inside and outside the wound, while the control group was treated with negative pressure drainage inside the wound. By two-week observation, the wound healing status and complication rate after treatment, as well as the wound bacterial clearance rate, wound pain score and patient satisfaction 3, 7 and 14 d after treatment were compared between the two groups. Statistical analysis was carried out to determine the efficacy.
After treatment for two weeks, the observation group showed a higher grade A healing rate (92% vs. 60%, X = 7.018, P = 0.008), a higher wound bacterial clearance rate (100% vs. 76%, X = 6.818, P = 0.03), a lower pain score (1.44 ± 0.51 vs. 2.36 ± 0.49, t = -6.53, P < 0.01), a higher patient satisfaction score (8.48 ± 0.96 vs. 6.64 ± 0.95, t = 6.80, P < 0.01), and a lower complication rate (8% vs. 40%, X = 7.018, P = 0.008) compared with the control group.
Double-tube negative pressure drainage has a significant application effect in the repair of refractory wounds. It can accelerate wound healing, shorten treatment time, effectively eliminate bacteria, relieve wound infection, reduce complications, alleviate pain and improve patient satisfaction. Therefore, the application, promotion and research of double-tube negative pressure drainage should be strengthened in clinical practice.
观察双管负压引流在难治性创面修复中的应用效果。
选取 2020 年 1 月至 2023 年 4 月在江苏省靖江市人民医院烧伤整形科行难治性创面修复的患者 50 例，根据不同治疗方法分为观察组和对照组，各 25 例。观察组采用内外双管负压引流治疗，对照组采用单纯内管负压引流治疗。通过两周的观察，比较两组患者的治疗后创面愈合情况及并发症发生率，以及治疗后 3、7、14 d 的创面细菌清除率、创面疼痛评分和患者满意度。采用统计学分析方法评估疗效。
治疗两周后，观察组愈合率 A 级（92% vs. 60%，X ²=7.018，P=0.008）、创面细菌清除率（100% vs. 76%，X ²=6.818，P=0.03）更高，疼痛评分（1.44±0.51 vs. 2.36±0.49，t=-6.53，P<0.01）更低，患者满意度评分（8.48±0.96 vs. 6.64±0.95，t=6.80，P<0.01）更高，并发症发生率（8% vs. 40%，X ²=7.018，P=0.008）更低。
双管负压引流在难治性创面修复中具有显著的应用效果。它可以加速创面愈合，缩短治疗时间，有效消除细菌，缓解创面感染，减少并发症，减轻疼痛，提高患者满意度。因此，应加强双管负压引流在临床实践中的应用、推广和研究。
