Single- versus three-dose cefoxitin prophylaxis in caesarean section: a randomized clinical trial

Area of Science:

• Obstetrics and Gynecology
• Infectious Diseases
• Pharmacology

Background:

• Caesarean section prophylaxis aims to prevent surgical site infections.
• Optimal antibiotic dosage for prophylaxis remains a subject of research.
• Cefoxitin is a commonly used antibiotic for surgical prophylaxis.

Purpose of the Study:

• To determine the minimal effective antibiotic dosage for caesarean section prophylaxis.
• To compare the efficacy of a single dose versus a three-dose regimen of cefoxitin.
• To evaluate the impact of different cefoxitin dosages on postoperative infection rates and hospital stay.

Main Methods:

• Prospective, double-blind study conducted at Amsterdam Free University Hospital.
• Compared one dose (2 g) of cefoxitin versus three doses (2, 1, 1 g) in 138 patients undergoing caesarean section.
• Assessed outcomes including febrile morbidity, endometritis, wound infection, urinary tract infection, and postoperative antibiotic use.

Main Results:

• The three-dose cefoxitin group demonstrated significantly fewer wound infections (p<0.05) and reduced need for postoperative antibiotic therapy (p<0.025).
• Patients receiving three doses had a shorter average hospital stay (9.8 +/- 1.5 days) compared to the one-dose group (10.6 +/- 2.6 days, p<0.05).
• No significant allergic or adverse reactions were observed in either group.

Conclusions:

• A three-administration regimen of cefoxitin is superior to a single dose for caesarean section prophylaxis.
• This finding contrasts with some existing literature, emphasizing the importance of dosage in antibiotic prophylaxis.
• The three-dose regimen is recommended for improved clinical outcomes and reduced healthcare resource utilization.
