肝移植术后脂肪液化伤口采用水胶体拉合免缝法联合负压治疗效果观察

Effect observation of hydrocolloid for closure without suture combined with negative pressure wound therapy in fat liquefaction incision after liver transplantation

目的探讨水胶体拉合免缝法联合负压治疗肝移植术后脂肪液化伤口的效果。方法 47例肝移植术后脂肪液化患者按照入院时间分组,2017年2月至2018年7月的患者分为对照组(26例),2018年8月至2019年12月的患者分为观察组(21例)。两组均行伤口评估及常规伤口床准备,对照组采用常规方法行伤口换药,观察组采用水胶体拉合免缝法联合负压治疗。结果两组伤口总愈合时间、总愈合速度、总换药时间、换药总次数、换药费用、单位时间伤口缩小面积、单位时间伤口深度改变、单位时间伤口愈合速度等指标比较,差异有统计学意义(均P<0.01)。结论水胶体拉合免缝法联合负压治疗能促进肝移植术后脂肪液化伤口愈合,且不增加经济负担,同时减轻护理工作量。

Objective To explore the effect of hydrocolloid for closure without suture combined with negative pressure wound therapy(NPWT) in patients with fat liquefaction after liver transplantation. Methods A total of 47 patients with fat liquefaction after liver transplantation were divided into two groups chronologically, the 26 patients hospitalized from February 2017 to July 2018 were defined as a control group, and other 21 patients hospitalized from August 2018 to December 2019 were regarded as an intervention group. The two groups received wound assessment and routine wound bed preparation, and the control group was treated with conventional dressing change, while the intervention group was treated with hydrocolloid for closure without suture combined with NPWT. Results The wound healing time, total healing speed, total wound dressing time, dressing frequency, treatment cost, change of wound area per unit time, change of wound depth per unit time, wound healing speed per unit time etc. between the two groups were significantly different(P<0.01 for all). Conclusion Hydrocolloid for closure without suture combined with NPWT promotes the healing of fat liquefaction wound after liver transplantation, it doesn’t add economic burden, and it reduces nursing work load.
