Single-dose antibiotic prophylaxis in high-risk patients undergoing cesarean section

Area of Science:

• Obstetrics and Gynecology
• Infectious Disease Prevention
• Surgical Prophylaxis

Background:

• Postoperative infectious complications are a significant concern following cesarean sections, particularly in high-risk patients.
• Antibiotic prophylaxis is a standard measure to mitigate these risks, but optimal dosing and timing remain areas of investigation.

Purpose of the Study:

• To evaluate the efficacy of a single-dose antibiotic prophylaxis regimen using ceftizoxime in preventing infectious complications after primary cesarean section.
• To compare the incidence of endometritis and febrile morbidity between patients receiving ceftizoxime and those receiving a placebo.

Main Methods:

• A prospective, double-blind, placebo-controlled study involving 100 high-risk women undergoing primary cesarean section.
• Participants were randomized to receive either a single 2-g dose of ceftizoxime or a placebo administered at the time of cord clamping.

Main Results:

• The incidence of endometritis was significantly lower in the ceftizoxime group (6.0%) compared to the placebo group (24.5%) (P < .05).
• Febrile morbidity also showed a significant reduction in the ceftizoxime group (14.0%) versus the placebo group (32.7%) (P < .05).

Conclusions:

• Single-dose ceftizoxime prophylaxis is effective in significantly decreasing the rates of endometritis and febrile morbidity in high-risk patients undergoing cesarean section.
• This prophylactic strategy represents a valuable approach to reducing infectious complications in this patient population.
