Abstract:
OBJECTIVE To explore the clinical characteristics and risk factors for surgical site infections(SSI)in the patients undergoing type Ⅰ incision surgeries of grade Ⅲ and Ⅳ so as to provide theoretical bases for effective prevention and control of SSI.METHODS The clinical data were prospectively collected from 280 patients with SSI who received major type Ⅰ incision surgeries of grade Ⅲ and Ⅳ in the key departments of the Second Affiliated Hospital of Jiaxing University from Jan.2021 to Jun.2024,and randomly from another 280 patients without infec-tions.The enrolled patients were assigned as the infection group and the no infection group,respectively.The clin-ical characteristics of the SSI were analyzed.The baseline data,including sex,age,hypertension,diabetes melli-tus,hyperlipidemia,heart disease,hepatorenal function,nutrition status,preoperative length of hospital stay,operation duration,implantation materials,emergency surgery,intraoperative warm maintenance,microscope,blood loss volume,blood transfusion and postoperative intensive care unit(ICU)stay as well as severe hypopro-teinemia,were collected from the enrolled patients.Univariate analysis and logistic regression analysis were per-formed for the influencing factors for the SSI.RESULTS A total of 16,706 patients underwent neurosurgery,or-thopedics and cardiothoracic surgery,280 of whom had SSI,the incidence of SSI was 1.68％.Totally 264 strains of bacteria were isolated,53.03％of which were gram-positive bacteria,46.97％were gram-negative bacteria;Staphylococcus aureus was the most common species of pathogenic bacteria.The result of multivariate logistic a-nalysis showed that the nutrition status,operation duration,microscope,postoperative ICU and severe hypopro-teinemia were the risk factors for the SSI(P＜0.05).CONCLUSIONS The SSI is common among the patients un-dergoing type Ⅰ incision surgeries of grade Ⅲ and Ⅳ.It is necessary for the hospital to take targeted interven-tion measures in early stage based on the risk factors.
