A survey of infections in stereotactic surgery
Abstract:
In 365 consecutive intracranial stereotactic procedures over a 6-year period, there were three postoperative infections; 1 case of increased neurological deficit and 1 of fatality. Staphylococcus aureus was the most common organism involved; however, multiple organisms were seen in 2 cases. Multiplicity of organisms necessitated the use of a broad spectrum of antibiotics in the preoperative and postoperative periods. The method described has permitted an infection rate which compares favorably to other reports in the literature. Perioperative antibiotics, antibiotic-containing irrigation solutions, and careful attention to sterile techniques seem to be instrumental in maintaining a low infection rate in our study. Since the new spheroid design has been used, there have been no infections.
Insights
Minimizing infection risk in stereotactic neurosurgery is crucial. This study highlights perioperative antibiotics and sterile techniques as key to achieving a low infection rate, with no infections reported after adopting a new spheroid design.
Area of Science:
- Neurosurgery
- Infectious Disease
- Medical Device Design
Background:
- Intracranial stereotactic procedures carry a risk of postoperative infection.
- Establishing effective infection control measures is vital for patient safety and procedural success.
Observation:
- Over a 6-year period, 365 intracranial stereotactic procedures resulted in three postoperative infections, one neurological deficit, and one fatality.
- Staphylococcus aureus was the predominant pathogen, with polymicrobial infections occurring in two cases.
- The use of broad-spectrum antibiotics was necessary due to the multiplicity of organisms.
Findings:
- The described methodology, incorporating perioperative antibiotics, antibiotic irrigation, and strict sterile techniques, achieved a favorable infection rate compared to existing literature.
- A significant finding was the complete absence of infections following the implementation of a new spheroid device design.
Implications:
- The study underscores the importance of comprehensive infection control strategies in stereotactic neurosurgery.
- The novel spheroid design shows promise for further reducing infection rates in neurosurgical interventions.
- Adherence to sterile protocols and judicious antibiotic use remain critical for preventing complications.
