Abstract
BACKGROUND: Surgical site infections after cesarean section are very common clinically, it is necessary to evaluate the risk factors of surgical site infections after cesarean section, to provide evidences for the treatment and nursing care of cesarean section. METHODS: This study was a retrospective cohort study design. Patients undergone cesarean section in a tertiary hospital of China from May 2017 to May 2020 were identified, we collected the clinical data of the included patients, and we analyzed the infection rate, etiological characteristics and related risk factors of surgical site infection after caesarean section. RESULTS: A total of 206 patients with cesarean section were included, and the incidence of surgical site infection in patients with cesarean section was 23.30%. A total of 62 cases of pathogens were identified, Enterococcus faecalis (33.87%) and Escherichia coli (29.03%) were the most common pathogens. Both Enterococcus faecalis and Escherichia coli were highly sensitive to Cefoperazone, Meropenem, and Levofloxacin. Logistic regression analyses indicated that Age ≥ 30y (OR 4.18, 95%CI: 1.23-7.09), BMI ≥ 24 (OR 2.39, 95%CI: 1.02-4.55), duration of cesarean section ≥ 1.5 h (OR 3.90, 95%CI: 1.28-5.42), estimated blood loss ≥ 400 ml (OR 2.35, 95%CI: 1.10-4.37) and the duration of urinary catheter ≥ 24 h (OR 3.18, 95% CI: 1.21-5.71) were the independent risk factors of surgical site infection after cesarean section (all p < 0.05). CONCLUSIONS: Age, BMI, duration of surgery, blood loss and urinary catheter use were associated with higher risk of the surgical site infection after cesarean section. Clinical preventions and interventions are warranted for those population to reduce the occurrence of surgical site infection.
