烧伤患者皮肤软组织扩张瘢痕修复术Ⅰ期术后感染影响因素分析

Analysis of influencing factors of infection after stage Ⅰ postoperative skin and soft tissue expansion scar repair in burned patients

目的 分析烧伤患者皮肤软组织扩张瘢痕修复术Ⅰ期术后感染相关影响因素。方法 回顾性分析2018年3月至2021年4月在上海长海医院行皮肤软组织扩张瘢痕修复术Ⅰ期的106例患者临床资料,统计烧伤患者住院期间切口感染发生情况及感染患者病原菌分布情况。采用logistic回归分析法分析影响患者感染发生的危险因素。结果 本研究行皮肤软组织扩张瘢痕修复术Ⅰ期的烧伤患者共11例,占比10.38%。11例感染患者中共检出菌株24株,革兰阴性菌、革兰阳性菌分别占比66.67%、33.33%。术前白细胞计数(WBC)、扩张囊容积均为烧伤患者皮肤软组织扩张瘢痕修复术Ⅰ期术后发生感染的危险因素(OR=2.838、3.340,P均<0.05)。结论 术前WBC、扩张囊容积均为影响烧伤患者皮肤软组织扩张瘢痕修复术Ⅰ期术后发生感染的危险因素。

Objective To analyze the influencing factors of postoperative infection in burn patients after stage Ⅰ expansion and scar repair of skin and soft tissues.Methods The clinical data of 106 patients who underwent stage Ⅰ skin and soft tissue expansion scar repair in Shanghai Changhai Hospital from March 2018 to April 2021 were retrospectively analyzed.Logistic regression analysis was used to analyze the risk factors affecting the occurrence of infection in patients.Results In this studythere were 11 cases of burn patients who underwent stage Ⅰ skin and soft tissue expansion scar repair,accounting for 10.38%.A total of 24 strains were detected in 11 infected patients,and Gram-negative bacteria and Gram-positive bacteria accounted for 66.67% and 33.33%,respectively.Preoperative white blood cell count( WBC) and dilatation capsule volume were both risk factors for postoperative infection in burn patients with skin and soft tissue dilation scar repair at stage Ⅰ( OR = 2.838,3.340,P < 0.05).Conclusions Preoperative WBC and dilatation capsule volume are both risk factors for postoperative infection in burn patients with skin and soft tissue dilation scar repair.
