目的

探究腹壁疝术后感染的危险因素分析。

方法

回顾性分析2020 年1 月至2023年1 月阜南县人民医院296 例接受腹壁疝手术患者的临床资料，根据患者术后是否发生感染，将其分为感染组（36 例）和未感染组（260 例），采用单因素及Logistic 回归分析筛选腹壁疝术后感染的危险因素。

结果

共纳入腹壁疝手术患者296 例，其中发生术后感染患者36 例，术后感染的发生率为12.16%（36/296）。感染组和未感染组的性别、体重指数、高血压、饮酒、吸烟、手术时长、肠坏死、腹壁疝病史、腹部手术史，术后1 d 白蛋白、降钙素原（PCT）、中性粒细胞与淋巴细胞比值（NLR）比较，差异无统计学意义（P＞0.05）；而年龄、切口感染、糖尿病、肠坏死、二次手术、术后1 d C 反应蛋白（CRP）、白细胞计数等资料比较，差异有统计学意义（P＜0.05）；进行二元Logistic 回归分析，结果显示年龄≥65 岁（OR=3.224）、伤口感染（OR=3.517）、糖尿病（OR=3.187）、肠坏死（OR=4.046）、二次手术（OR=3.543）、术后1 d CRP（OR=3.701）、白细胞计数（OR=4.061）是发生腹壁疝术后感染的危险因素（P＜0.05）。

结论

年龄、伤口感染、糖尿病、肠坏死、二次手术、术后1 d CRP、白细胞计数是腹壁疝术后感染的危险因素，根据其危险因素进行针对性的干预可有效降低腹壁疝术后感染。

Objective

To investigate the risk factors for postoperative infection in patients undergoing abdominal wall hernia surgery.

Methods

A retrospective analysis was conducted on the clinical data of 296 patients who underwent abdominal wall hernia surgery at Funan County People's Hospital from January 2020 to January 2023.Based on whether postoperative infection occurred, patients were divided into an infection group (36 cases) and a non-infection group (260 cases).Univariate analysis and logistic regression analysis were used to identify risk factors for postoperative infection.

Results

A total of 296 patients who underwent abdominal wall hernia surgery were included, with 36 patients experiencing postoperative infections, resulting in an infection rate of 12.16% (36/296).There were no statistically significant differences between the infection and non-infection groups in terms of sex, body mass index, hypertension, alcohol consumption, smoking, operation duration, bowel necrosis, history of abdominal wall hernia, history of abdominal surgery, postoperative day 1 albumin levels, procalcitonin(PCT), or the neutrophil-to-lymphocyte ratio (NLR) (P＞0.05).However, significant differences were observed between the groups regarding age, wound infection, diabetes mellitus, bowel necrosis, reoperation,postoperative day 1 C-reactive protein (CRP), and white blood cell count (P＜0.05).Binary logistic regression analysis identified age ≥65 years (OR=3.224), wound infection (OR=3.517), diabetes mellitus(OR=3.187), bowel necrosis (OR=4.046), reoperation (OR=3.543), postoperative day 1 CRP (OR=3.701),and white blood cell count (OR=4.061) as significant risk factors for postoperative infection (P＜0.05).

Conclusion

Age, wound infection, diabetes mellitus, bowel necrosis, reoperation, postoperative day 1 CRP, and white blood cell count are risk factors for postoperative infection in patients undergoing abdominal wall hernia surgery.Targeted interventions based on these risk factors can effectively reduce the incidence of postoperative infections.
