Summary
Longer neurosurgical procedures increase infection risk. Antibiotic prophylaxis showed no significant benefit in this study, highlighting the need for tailored strategies based on unit-specific microbial environments.
Area of Science:
- Neurosurgery
- Infectious Disease Epidemiology
Background:
- Surgical site infections (SSIs) are a significant concern in neurosurgery.
- Long-duration procedures (>6 hours) may present a higher risk of infectious complications.
Purpose of the Study:
- To determine the frequency of infectious complications after long-duration neurosurgical procedures.
- To evaluate the impact of antibiotic prophylaxis on these complications.
Main Methods:
- Retrospective analysis of 6,702 neurosurgical procedures.
- Comparison of infection rates between procedures >6 hours and the overall cohort.
- Assessment of antibiotic prophylaxis use and its correlation with infection rates.
Main Results:
- Procedures >6 hours had a 13.8% infection rate versus 1.43% for all procedures.
- No significant difference in infection rates was observed with or without antibiotic prophylaxis.
- Klebsiella was a frequent pathogen, linked to intensive care unit contamination.
Conclusions:
- Long duration is a risk factor for neurosurgical infections.
- Current antibiotic prophylaxis strategies may require re-evaluation.
- Tailoring prophylaxis to the specific microbial environment of the care unit is crucial.
