Perioperative antibiotic prophylaxis duration impacts infection risk in cranial base surgery. Short-term prophylaxis (≤24 hours) increases infection risk, while 48-hour prophylaxis is recommended for optimal outcomes.

Area of Science:

  • Neurosurgery
  • Infectious Disease
  • Surgical Oncology

Background:

  • Clean-contaminated cranial base surgeries carry a risk of surgical site infections.
  • The optimal duration of perioperative antibiotic prophylaxis in these procedures is not well-established.

Purpose of the Study:

  • To investigate the role of perioperative antibiotic prophylaxis in preventing infections after clean-contaminated cranial base surgeries.
  • To identify risk factors associated with local infection in this patient population.

Main Methods:

  • Retrospective analysis of 95 patients undergoing 100 clean-contaminated cranial base surgeries.
  • Evaluation of various antibiotic prophylaxis regimens and their correlation with infection development.
  • Analysis of potential risk factors including surgical approach, reconstruction type, surgery duration, and drain use.

Main Results:

  • Seven patients (7%) developed surgical site infections, including meningitis, intracranial abscess, cellulitis/abscess, and osteomyelitis.
  • Antibiotic prophylaxis of 24 hours or less was significantly associated with an increased risk of infection (p < 0.04).
  • Prolonged prophylaxis (>48 hours) showed no additional benefit over 48-hour prophylaxis. Surgical factors were not significantly correlated with infection.

Conclusions:

  • The risk of intracranial infection is low, even with intraoperative bacterial contamination.
  • Perioperative antibiotic prophylaxis covering gram-positive and gram-negative organisms for at least 48 hours is recommended.
  • Meticulous surgical technique remains crucial for preventing infectious complications.
