自制简易负压引流装置联合普朗特液体伤口敷料治疗腹部感染性伤口的效果分析

Self-made negative pressure drainage technique combined with Prontosan^(■) for abdominal wound infection

目的分析自制简易负压引流装置联合普朗特液体伤口敷料治疗腹部感染性伤口的效果。方法回顾性分析2019年1月至2020年12月我院收治的45例腹部手术后发生伤口感染患者的临床资料,按照伤口换药处置方式的不同,将患者分为普通换药组(n=14)、自制负压引流组(n=15,使用自制简易负压引流装置)及联合治疗组(n=16,使用自制简易负压引流装置联合普朗特液体伤口敷料)。比较三组创面愈合及伤口深度变化情况。结果三组创面初始面积比较差异无统计学意义(P>0.05)。在换药第3、7、10天时,自制负压引流组、联合治疗组创面愈合百分率均高于普通换药组,在换药第10天时,联合治疗组创面愈合百分率高于自制负压引流组(均P<0.05)。联合治疗组创面愈合时间短于普通换药组、自制负压引流组(均P<0.05)。三组伤口深度随时间增长呈逐渐变浅趋势(均P<0.05),普通换药组初始伤口深度与换药第3天时伤口深度比较差异无统计学意义(P>0.05),余各组内不同测量时间点伤口深度比较差异均有统计学意义(均P<0.05)。在初始测量及换药第3天时,三组伤口深度比较差异均无统计学意义(均P>0.05)。在换药第7天时,三组伤口深度比较差异有统计学意义(P<0.05),联合治疗组伤口深度较其余两组浅(均P<0.05)。在换药第10天时,三组伤口深度比较差异有统计学意义(P<0.05),联合治疗组伤口深度较其余两组浅,自制负压引流组伤口深度较普通换药组浅(均P<0.05)。结论在腹部感染性伤口治疗过程中,自制简易负压引流装置与普朗特液体伤口敷料的联合使用对促进创面愈合有较为理想的效果,具有良好的临床应用价值。

Objectives To investigate the efficacy of self-made negative pressure drainage technique combined with Prontosan^(■) for abdominal wound infection.Methods This was a retrospective analysis of 45 patients who experienced wound infection after abdominal surgery at our hospital between January 2019 and December 2020.Depending on the dressing change technique,patients were divided into Group A(n=14,receiving routine wound dressing change),Group B(n=15,receiving self-made negative pressure drainage technique),and Group C(n=16,receiving the combination of self-made negative pressure drainage technique and Prontosan®).Wound healing and changes in wound depth were compared among the three groups.Results The three groups did not differ significantly in the initial wound area(P>0.05).Wound healing rate on the 3rd,7th,and 10th day was significantly higher in Group B and C than in Group A(P<0.05).The wound healing rate on the 10th day was significantly higher in Group C than in Group B(P<0.05).Wound healing time was significantly shorter in Group C than in Group A and B(P<0.05).Wound depth decreased gradually over time in all three groups(P<0.05).In Group A,wound depth on the 3rd day was similar to the initial wound depth(P>0.05),while there were differences between every two remaining time points(P<0.05).In Group B and C,wound depth at different time points differed significantly(P<0.05).Initial wound depth and wound depth on the 3rd day was similar among the three groups(P>0.05).Wound depth on the 7th day was significantly different among the three groups,with smaller wound depth in Group C than in the other two groups(P<0.05).Wound depth at the 10th day was significantly different among the three groups,with smaller wound depth in Group C than in the other two groups,and smaller wound depth in Group B than in Group A(P<0.05).Conclusion For abdominal wound infection,the combination of self-made negative pressure drainage technique with Prontosan®was beneficial for wound healing.It has a potential for clinical use.
