A randomized prospective study of antibiotic prophylaxis during abdominal surgery

Area of Science:

• Infectious Diseases
• Surgical Prophylaxis
• Pharmacology

Background:

• Antibiotic prophylaxis is crucial in preventing surgical site infections (SSIs) after abdominal operations.
• Cefoxitin has been a standard prophylactic agent, but alternatives are continually evaluated for comparable efficacy and safety.
• Intravenous cefmetazole is a potential alternative for perioperative antibiotic prophylaxis.

Purpose of the Study:

• To compare the safety and efficacy of intravenous cefmetazole versus intravenous cefoxitin for antibiotic prophylaxis in patients undergoing abdominal operations.
• To determine if cefmetazole offers a comparable prophylactic profile to cefoxitin in a prospective, randomized clinical trial.

Main Methods:

• A randomized, prospective clinical study was conducted.
• Eighty-nine evaluable patients undergoing abdominal operations, primarily clean/contaminated and contaminated procedures, were enrolled.
• Patients received either intravenous cefmetazole or intravenous cefoxitin for prophylaxis.

Main Results:

• A low overall rate of postoperative wound infections (3%) and non-life-threatening adverse drug reactions (2%) was observed.
• No statistically significant differences were found between the cefmetazole and cefoxitin groups regarding infection rates or adverse events.
• No life-threatening adverse drug reactions were reported in either treatment group.

Conclusions:

• Intravenous cefmetazole demonstrates comparable safety and efficacy to intravenous cefoxitin for prophylactic use in abdominal operations.
• Cefmetazole represents a suitable alternative antibiotic for surgical prophylaxis in this patient population.
• The study supports the use of cefmetazole as an effective option for preventing infections in intra-abdominal surgeries.
