负压封闭引流对Ⅱ度烧伤患儿创面愈合及疼痛的影响

Effect of the negative pressure closed drainage on the wound healing and pain in children with second-degree burns

目的探究在Ⅱ度烧伤患儿的临床治疗中运用负压封闭引流技术的效果及对创面愈合和疼痛的影响。方法选择北海市人民医院2019年1月—2021年12月收治的Ⅱ度烧伤患儿55例,以随机分配的原则进行分组,对照组(n=28)给予常规的烧伤换药治疗,研究组(n=27)则在常规烧伤换药治疗基础上采取负压封闭引流术进行治疗,分别观察统计治疗1周、2周和3周后的创面愈合情况,并详细记录患儿体温持续时间、创面平均愈合时间、疤痕指数、换药次数和住院时间,采用视觉模拟评分法(VAS)分析患儿治疗前后的疼痛程度。结果研究组患儿在治疗1周、2周和3周后的创面愈合率分别为44.44%、77.78%和100.00%,均优于对照组同一时段的愈合率(P<0.05);且研究组患儿体温持续时间、创面平均愈合时间、住院时间分别为(18.27±1.74)h、(25.17±2.48)d、(14.42±1.25)d,均短于对照组,疤痕指数、换药次数分别为(5.02±1.06)、(2.21±0.16)次,均低于对照组,差异有统计学意义(P<0.001);研究组患儿治疗后VAS评分为(2.04±0.31)分,低于对照组(P<0.001)。结论在Ⅱ度烧伤患儿的临床治疗中运用负压封闭引流技术的效果更为理想,能够有效地促进患儿创面愈合,减轻患者的疼痛程度,减少感染概率,安全性较高,值得推广。

Objective To explore the effectiveness of the application of negative pressure closed drainage in the clinical treatment of children with second-degree burns and its influence on the wound healing and pain.Methods 55 children with superficial second-degree burns admitted into Beihai People's Hospital from January 2019 to December 2021 were selected and divided into two groups on the principle of random allocation.Control group(n=28)were given the conventional treatment of burn dressing changes,and study group(n=27)were additionally treated with the negative pressure closed drainage on the basis of conventional treatment of burn dressing changes.The wound healing progress,duration of body temperature,average wound healing time,scar indexes,frequency of dressing changes and length of hospital stays for both groups were closely observed and recorded at the end of the 1st week,the 2nd week and the 3rd week of treatment.And visual analogue scale(VAS)was also used to analyze the degree of pain in children before and after treatment.Results The wound healing rates of the study group at the end of the 1st week,2nd week and 3rd week of treatment were 44.44%,77.78%and 100.00%respectively,which were better than those of the control group at the same period(P<0.05).In addition,the duration of body temperature,average wound healing time,and length of hospital stay of the study group were(18.27±1.74)h,(25.17±2.48)d,and(14.42±1.25)d respectively,which were all shorter than those of the control group,and the scar index and the number of dressing changes of the study group were(5.02±1.06)and(2.21±0.16)times respectively,which were also lower than those of the control group,and difference was statistically significant(P<0.001).The children's VAS score in the study group after treatment was(2.04±0.31),lower than that of the control group(P<0.001).Conclusion The effect of the clinical treatment with negative pressure closed drainage on children with second-degree burns is more ideal.It can effectively promote the wound healing,alleviate the degree of pain,and reduce the probability of infection with high safety,which is worthy of promotion.
