A single dose of cefazolin is as effective as multiple doses for preventing febrile morbidity after cesarean section in high-risk women. This finding supports single-dose antibiotic prophylaxis in obstetric surgery.

Area of Science:

  • Obstetrics and Gynecology
  • Infectious Disease Prevention
  • Surgical Site Infection Prophylaxis

Background:

  • Postoperative febrile morbidity is a common complication following cesarean section.
  • Antibiotic prophylaxis is standard practice, but optimal dosing regimens require further investigation.
  • Identifying effective, minimally burdensome prophylactic strategies is crucial for patient care.

Purpose of the Study:

  • To compare the efficacy of a single-dose versus a three-dose regimen of cefazolin for preventing febrile morbidity in high-risk cesarean section patients.
  • To evaluate the incidence of endometritis in relation to different cefazolin prophylaxis strategies.
  • To assess the febrile morbidity in an untreated low-risk group for comparison.

Main Methods:

  • Prospective, randomized trial involving 100 high-risk women undergoing cesarean section.

  • Group 1: Single 1 gm intravenous dose of cefazolin.
  • Group 2: Three-dose regimen of cefazolin (1 gm initial dose, followed by two doses 8 hours apart).
  • Group 3: 50 low-risk women receiving no antibiotic prophylaxis.

    • Main Results:

    • Febrile morbidity rates were similar between the single-dose (18%) and three-dose (12%) cefazolin groups.
    • Endometritis rates were also comparable: 6% in the single-dose group and 8% in the three-dose group.
    • The untreated low-risk group showed no endometritis and comparable febrile morbidity (14%) to the treated groups (15%).

    Conclusions:

    • Single-dose cefazolin prophylaxis is as effective as multidose prophylaxis in reducing febrile morbidity after cesarean section.
    • The findings suggest that single-dose prophylaxis may be a viable and efficient option for preventing postoperative febrile morbidity in cesarean deliveries.
    • Further research could explore the cost-effectiveness and broader applicability of single-dose regimens in various surgical settings.
