Summary

A single preoperative dose of ceftriaxone (1 g) is effective for short-term antimicrobial prophylaxis in maxillofacial surgery. This approach meets pharmacokinetic needs, showing comparable efficacy to a multi-dose regimen.

Area of Science:

  • Infectious Diseases
  • Pharmacology
  • Surgical Oncology

Background:

  • Antimicrobial prophylaxis is crucial in maxillofacial surgery to prevent surgical site infections.
  • Short-term prophylactic regimens aim to balance efficacy with reduced antibiotic exposure.

Purpose of the Study:

  • To compare the clinical efficacy of single-dose ceftriaxone versus a multi-dose regimen of mezlocillin/oxacillin for perioperative antimicrobial prophylaxis in maxillofacial surgery.
  • To assess the pharmacokinetic profile of these antibiotics in tissue and plasma.

Main Methods:

  • Prospective randomized clinical study involving 100 patients undergoing elective maxillofacial surgery.
  • Antibiotic concentrations (ceftriaxone, mezlocillin, oxacillin) measured in tissue and plasma using high-pressure liquid chromatography.

  • Statistical comparison of demographic data, surgical procedures, and infection rates between groups.

    • Main Results:

    • Both treatment groups were demographically comparable and had similar surgical procedure types and durations.
    • Postoperative wound infection rates were low and comparable, with only one infection in each group.
    • Ceftriaxone achieved adequate tissue and plasma concentrations, meeting pharmacokinetic requirements for prophylaxis.

    Conclusions:

    • Single-dose (1 g) preoperative ceftriaxone is a clinically effective and pharmacokinetically suitable option for perioperative antimicrobial prophylaxis in maxillofacial surgery.
    • This regimen demonstrates comparable efficacy to a multi-dose regimen, potentially simplifying treatment protocols.
