RESUMO

Background: Post-partum infection is a major contributor to maternal mortality and is responsible for approximately 10% of maternal fatalities worldwide. The risk of infection is substantially higher in cesarean section procedures. Approximately 8% of women who undergo cesarean sections are susceptible to infection. Although the body of evidence supporting the regular pre-operative utilization of prophylactic antibiotic treatment is steadily expanding, its usefulness in cesarean sections has not yet been standardized, and post-partum infection is still a serious medical challenge. We aimed to retrospectively assess the prophylactic effectiveness of cefazolin in combination with other antibiotic agents in cesarean sections. Materials and Methods: Both uni-variable and multi-variable analyses were conducted to identify factors that may affect cefazolin pre-operative antibiotic prophylaxis in elective cesarean section operations. The uni-variable analysis included timing of administration, operation duration, body mass index (BMI), and wound type. A multi-variable logistic regression model was then created to determine which variables provide independent information in the context of other variables. Results: Time of administration did not affect prophylactic cefazolin efficacy. However, prophylactic cefazolin was 1.43 and 1.77 times more effective when the operation lasted for 45 minutes or more, compared with operations that were shorter than 45 minutes. Patients with a BMI ranging from 18 to 29 kg/m2 showed increased efficacy of prophylactic cefazolin compared with obese patients with a BMI exceeding 30 kg/m2. The effectiveness of prophylactic cefazolin decreased by 95% in patients with clean-contaminated surgical incisions compared with those with clean surgical incisions. Conclusions: Our findings demonstrate that administering pre-operative prophylactic antibiotic agents to women undergoing cesarean section resulted in a reduction in post-partum infections, thereby reducing maternal mortality. Furthermore, optimal timing of administration, re-dosing if necessary, length of prophylactic medication, and dosing adjustments for obese patients are crucial factors in preventing surgical site infections and promoting antimicrobial stewardship.
