Single-dose cefotetan versus multiple-dose cefoxitin as prophylaxis in colorectal surgery

Area of Science:

• Infectious Diseases
• Surgical Oncology
• Pharmacology

Background:

• Postoperative infectious complications are a significant concern following colorectal surgery.
• Antibiotic prophylaxis is standard to mitigate these risks.
• Comparing different antibiotic regimens is crucial for optimizing patient outcomes.

Purpose of the Study:

• To evaluate the safety and efficacy of a single preoperative dose of cefotetan compared to multiple perioperative doses of cefoxitin.
• To assess the impact on postoperative infectious complications after colorectal surgery.

Main Methods:

• A multicenter trial involving 289 patients undergoing colorectal surgery.
• Comparison of a single 2g preoperative dose of cefotetan versus multiple 2g perioperative doses of cefoxitin.
• Evaluation of clinical response rates, bacteriologic response, temperature changes, infection incidence, and adverse reactions.

Main Results:

• No statistically significant difference in successful clinical response rates between cefotetan (88%) and cefoxitin (92%).
• Similar satisfactory bacteriologic response rates (88% for cefotetan, 93% for cefoxitin).
• Incidence of major wound infection was approximately 8% in both groups, with comparable adverse reaction rates (12%).

Conclusions:

• A single preoperative dose of cefotetan is a safe and effective alternative to multiple doses of cefoxitin for reducing postoperative wound infections in colorectal surgery.
• Factors like non-obesity and shorter surgical duration (<4 hours) correlated with higher success rates for both antibiotics.
