An Antibiotic Prophylaxis for Prevention of Ventriculoperitoneal Shunt Infection Using Intraventricular Injection and...

Area of Science:

• Neurosurgery
• Infectious Disease Prevention
• Medical Device Infections

Background:

• Limited evidence exists for intraventricular injection and shunt soaking with vancomycin-gentamicin as shunt infection prophylaxis.
• Ventriculoperitoneal (VP) shunt infections pose significant risks to patients.

Purpose of the Study:

• To evaluate the efficacy of a combined intraventricular injection and shunt soaking technique using vancomycin-gentamicin in preventing VP shunt infections.
• To identify factors associated with VP shunt infection one year postoperatively.

Main Methods:

• Retrospective cohort study including patients who received VP shunt placement.
• Primary outcome: VP shunt infection within one year post-operation.
• Logistic regression analysis to determine associated factors.

Main Results:

• Out of 413 patients, 31 (7.51%) developed VP shunt infections within one year.
• Independent factors associated with infection: younger age, brain tumor etiology, and the intraventricular injection and shunt soaking technique.
• The prophylaxis technique showed an adjusted odds ratio of 0.422 for infection.

Conclusions:

• The combined vancomycin-gentamicin intraventricular injection and shunt soaking technique may decrease VP shunt infection rates.
• Younger patients (under 8 years) may be at increased risk.
• Further prospective randomized controlled trials are recommended to validate these findings.
