Prevention of neurosurgical infection by intraoperative antibiotics
Abstract:
For the past 5 years at Mount Sinai Hospital, an intraoperative prophylactic antibiotic regime consisting of intramuscular gentamicin or tobramycin, intravenous vancomycin, and streptomycin irrigating solution, with no preoperative or post operative antibiotics, has provided complete protection against operative infections in neurological surgery. There have been 1732 major clean operative cases with no instance of operative infection and no complication due to the antibiotics.
Insights
A novel prophylactic antibiotic regimen, including gentamicin/tobramycin, vancomycin, and streptomycin irrigation, completely prevented surgical site infections in 1732 neurological surgery cases over 5 years. This approach avoided pre- and post-operative antibiotics without complications.
Area of Science:
- Neurosurgery
- Infectious Disease Prevention
- Pharmacology
Background:
- Surgical site infections (SSIs) are a significant concern in neurological surgery.
- Traditional antibiotic prophylaxis often involves pre- and post-operative administration.
- Optimizing antibiotic strategies is crucial for patient safety and outcomes.
Purpose of the Study:
- To evaluate the efficacy of an intraoperative-only prophylactic antibiotic regimen in preventing surgical infections in neurological surgery.
- To assess the safety and complication profile of the described antibiotic protocol.
Main Methods:
- A 5-year retrospective analysis of 1732 major clean neurosurgical cases at Mount Sinai Hospital.
- Implementation of an intraoperative antibiotic regimen: intramuscular gentamicin or tobramycin, intravenous vancomycin, and streptomycin irrigating solution.
- Exclusion of all pre-operative and post-operative antibiotic administration.
Main Results:
- Complete absence of operative infections across all 1732 cases.
- No reported complications or adverse events related to the antibiotic regimen.
- Demonstrated effectiveness of the intraoperative-only approach in a large cohort.
Conclusions:
- An intraoperative-only prophylactic antibiotic regimen is highly effective in preventing surgical site infections in neurological surgery.
- This targeted approach eliminates the need for pre- and post-operative antibiotics, simplifying protocols and potentially reducing antibiotic resistance.
- The described regimen is safe and well-tolerated, offering a viable alternative for infection control in neurosurgical procedures.
