脉冲短波促进烧伤患儿创面愈合的效果观察

Efficacy of pulsed shortwave diathermy on wound healing in children with burns

目的观察脉冲短波对上肢烧伤患儿创面的促愈合效果,并对其作用机制进行初步探讨。方法选取西南医科大学附属医院整形烧伤科2021年6月至2023年6月收治的40例上肢深二度烧伤患儿,按随机数字表法分为对照组和观察组,每组各20例。对照组患儿采用常规换药治疗;观察组患儿从烧伤后采用常规换药联合脉冲短波治疗。记录患儿创面愈合时间、创面再生上皮岛首次出现时间及首次再生上皮岛数目;采用eKare inSight 3D创面管理系统观察创面肉芽面积占比;采集创面分泌物行细菌培养检查,观察2组患儿创面细菌阳性率;采用血流测量仪检测患儿创面血流灌注量。结果观察组患儿创面愈合时间和再生上皮岛首次出现时间均快于对照组(P<0.05)。观察组患儿创面肉芽组织生长速度明显快于对照组(P<0.05)。同时,观察组患儿创面细菌感染控制情况优于对照组(P<0.05)。血流测量仪检测结果显示观察组患儿创面在脉冲短波治疗后血流灌注量没有明显增加(P>0.05),随着时间的推移,2组患儿创面血流灌注均呈升高的状态(P<0.05)。结论脉冲短波可通过促进创面坏死组织清除、肉芽组织再生而有效促进烧伤患儿创面的愈合速度,推测其机制可能与脉冲短波的非热效应有关。

Objective To observe the promoting effect of pulsed shortwave therapy on wound healing in pediatric patients with upper limb burns and explore its underlying mechanisms.Methods A total of 40 children with deepⅡ°upper limb burns treated in our hospital from June 2021 to June 2023 were enrolled,and randomly divided into a control group and an observation group,with 20 cases in each group.The control group received conventional dressings,and the observation group received conventional dressings combined with pulsed shortwave therapy.The wound healing time,first appearance of skin islands on the wound,and initial number of skin islands were observed and recorded using a camera.The proportion of granulation tissue area in the wound was observed using eKare inSight 3D.The positive rate of wound bacteria was detected by collecting wound secretions for bacterial culture examination.Blood flow perfusion on the wound was measured using a blood flow meter.Results The observation group showed significantly faster wound healing and initial appearance of epithelialization(P<0.05),and obviously higher rate of granulation tissue growth than the control group(P<0.05).Moreover,the observation group demonstrated better control of bacterial infection in the wounds than the control group(P<0.05).Blood flow measurement results revealed no significant increase in blood flow perfusion after pulsed shortwave therapy in the observation group(P>0.05).However,with the elapse of time,both groups exhibited an increasing trend in blood flow perfusion(P<0.05).Conclusion Pulsed shortwave therapy effectively promotes wound healing in pediatric patients with burns,by facilitating necrotic tissue clearance and granulation tissue regeneration,which may be associated with its non-thermal effects.
