负压吸疱术修复烧伤残余创面的临床疗效观察

The efficacy of negative pressure suction blister in treatment of residual burn wounds

目的对比分析传统换药方法与负压吸疱术修复烧伤残余创面的临床疗效。方法选取50例烧伤残余创面患者,随机分为实验组(负压吸疱术)和观察组(传统换药),每组25例。比较两组患者治疗后各时间段创面愈合率、分泌物细菌培养阳性率、愈合时间及住院时间,分析不良反应。结果实验组患者治疗后10、15、30d内创面愈合率显著高于对照组患者,差异具有统计学意义(P<0.01);创面愈合时间和住院时间较对照组患者均显著缩短,差异具有统计学意义(P<0.001);创面分泌物细菌培养阳性率较对照组患者低,差异具有统计学意义(P<0.001)。治疗过程中均未出现不良反应。结论本次研究表明负压吸疱术修复烧伤残余创面,明显缩短创面愈合时间,减少创面感染,避免感染加深和扩大创面,且安全、可靠,值得进一步在临床上推广应用。

Objective This article aims to compare the efficacy of traditional dressing method and negative pressure suction blister technique for treatment of burn remnant wounds. Methods Fifty burn patients with residual wounds were selected and were randomly divided into an experimental group （n =25,patients received negative pressure suction blister technique）and an observation group （n =25,patients received conventional treatment）.The comparison of post-treatment wound healing rate at each time points,the positive- bacteria rate of wound secretion culture,wound healing time and hospitalization duration between the two groups were done and adverse reactions were analyzed. Results Patients in the experimental group had higher post -treatment wound healing rate on 10,15,30 days than those of the control group patients,there were statisti-cally significant differences （P 〈0.01）.The wound healing time and hospitalization duration for the observa-tion group were significantly shorter than those of the control group patients,there were statistically significant differences （P 〈0.001 ）;the positive-bacteria rate of wound secretion culture was lower than those of the control group patients,there were statistically significant differences （P 〈0.001 ）.No adverse reactions oc-curred in the two groups during the course of treatment. Conclusion The research results suggest that nega-tive pressure suction blister technique can safely and reliably repair burn remnant wounds,which can signifi-cantly shorten the wound healing time,reduce the wound infection,avoid the wound deepening and widening, and be worthy of further clinical recommendation.
