Analysis of risk factors related to periprosthetic infection after breast augmentation / 中国修复重建外科杂志

ABSTRACT

Objective: To explore the risk factors related to periprosthetic infection after breast augmentation, and to provide a basis for reducing the risk of postoperative infection. Methods: A total of 1 056 female patients who underwent breast augmentation between January 2010 and January 2018 were analyzed retrospectively. The patients were 20 to 44 years old (mean, 31.6 years). The body mass index (BMI) was 19.0-31.1 kg/m 2, with an average of 24.47 kg/m 2. According to the periprosthetic infection standard of the United States Centers for Disease Control and Prevention (CDC), the patients were divided into infection group and non-infection group. Age, BMI, diabetes, previous history of immunosuppression, history of smoking, previous history of breast surgery, previous history of mastitis, combined with active dermatitis, surgical approach, the type and shape of breast prosthesis, implant in the different layers, combined with mastopexy, operation time, postoperative antibiotic time, postoperative breast crash, and postoperative potential infection surgery were analyzed by univariate analysis. The influencing factors of prosthetic infection were screened by logistic regression. Results: Periprosthetic infection occurred in 60 cases after operation, and the infection rate was 5.68%. Among them, 11 cases were acute infection, 33 cases were subacute infection, 16 cases were delayed infection, and 20 cases were positive in bacterial culture. Postoperative breast crash occurred in 114 cases. Univariate analysis showed that diabetes, previous history of immunosuppression, history of smoking, previous history of mastitis, postoperative breast crash, postoperative potential infection surgery, and combined with breast suspension were the influencing factors of postoperative periprosthetic infection ( P<0.05). Multivariate analysis showed that diabetes, history of smoking, and postoperative breast crash were the risk factors of periprosthetic infection ( P<0.05). Conclusion: Diabetes, smoking, and postoperative breast crash are the risk factors of periprosthetic infection after breast augmentation.
