Risk factors in cesarean section infection

Area of Science:

• Obstetrics and Gynecology
• Infectious Disease Epidemiology

Background:

• Postoperative infections following cesarean sections are a significant concern.
• Understanding risk factors is crucial for prevention strategies.

Purpose of the Study:

• To identify factors associated with postoperative infection risk in patients undergoing cesarean section without antibiotic prophylaxis.
• To compare infection rates between emergency and elective cesarean sections.

Main Methods:

• A study of 321 patients who did not receive antibiotic prophylaxis.
• Analysis of infection occurrence based on type of cesarean section (emergency vs. elective).
• Identification and evaluation of potential risk factors for infection.

Main Results:

• Infection rates were significantly higher in emergency cesarean sections (25%) compared to elective ones (9%).
• Identified risk factors included: operation duration > 1 hour, blood loss > 800 ml, Staphylococcus aureus nasal carriage, intrauterine infection signs, and labor progression failure.
• Observed infection rates were comparable to those reported in studies with antibiotic use.

Conclusions:

• Emergency cesarean sections carry a substantially higher risk of postoperative infection.
• Specific patient and procedural factors, rather than obstetric interventions themselves, are linked to infection risk.
• Emphasizes the critical importance of rigorous preoperative hygienic practices to mitigate infection risk.
