Insights
For pediatric neurosurgery, single-dose antimicrobial prophylaxis (AMP) is as effective as multiple-dose AMP. This study found no significant benefit of multiple doses, suggesting single-dose AMP is sufficient and avoids unnecessary antibiotic exposure.
Area of Science:
- Neurosurgery
- Pediatric Medicine
- Infectious Disease Prevention
Background:
- Current guidelines recommend antimicrobial prophylaxis (AMP) for clean neurosurgical procedures.
- The optimal dosing strategy (single vs. multiple doses) for AMP in pediatric neurosurgery remains debated.
- This study addresses the controversy surrounding multiple-dose AMP in pediatric cranial and spinal surgeries.
Purpose of the Study:
- To compare the efficacy of single-dose versus multiple-dose antimicrobial prophylaxis (AMP) in pediatric neurosurgery.
- To evaluate surgical site infection rates between single-dose and multiple-dose AMP cohorts.
- To determine if multiple-dose AMP offers a significant benefit over single-dose AMP in pediatric cranial and spinal surgeries.
Main Methods:
- Retrospective analysis of 300 pediatric neurosurgery patients (28 days to 18 years) at a single tertiary center.
- Propensity score matching created three 50-patient arms for single-dose and multiple-dose AMP in noninstrumented spinal, noninstrumented cranial, and instrumented cranial surgeries.
- Logistic regression analysis adjusted for etiology was used to compare outcomes, with equivalence analysis using a prior meta-analysis.
Main Results:
- No statistically significant difference in surgical site infections was observed between single-dose and multiple-dose AMP groups across all cohorts.
- Equivalence analysis showed non-discriminating results for the total cohort (adjusted OR 0.65) and subcohorts (ORs ranging from 0.52 to 0.68).
- No statistically significant intercohort differences were found based on etiology or surgical procedure type.
Conclusions:
- Single-dose antimicrobial prophylaxis (AMP) is as effective as multiple-dose AMP in pediatric neurosurgery.
- There is no detected significant benefit of using multiple-dose AMP over single-dose AMP for clean cranial and spinal neurosurgical interventions.
- To minimize unnecessary antibiotic exposure, single-dose AMP is indicated for pediatric neurosurgical procedures.
Objective:
Guidelines recommend antimicrobial prophylaxis (AMP) preoperatively for "clean" spinal and cranial surgeries, while dose and timing remain controversial. The use of multiple-dose AMP for such surgeries is under debate in the pediatric context. In this clinical study, the authors aimed to compare single-dose with multiple-dose prophylactic antibiotic usage in cranial and spinal neurosurgical interventions of pediatric patients.
Methods:
All neurosurgical patients aged 28 days to 18 years who underwent surgery at a single tertiary center were assessed. Three cohorts (noninstrumented clean spinal, noninstrumented cranial, and instrumented cranial interventions), each of which comprised two 50-patient arms (i.e., single-dose AMP and multiple-dose AMP), were included after propensity score-matched retrospective sampling and power analysis. Records were examined for surgical site infections. Using a previously published meta-analysis as the prior and 80% acceptance of equivalence (margin of OR 0.88-1.13), logistic regression was carried out for the total cohort and each subcohort and adjusted for etiology by consideration of multiple-dose AMP as reference.
Results:
The overall sample included 300 age- and sex-matched patients who were evenly distributed in 3 bi-arm cohorts. There was no statistical intercohort difference based on etiology or type of operation (p < 0.05). Equivalence analysis revealed nondiscriminating results for the total cohort (adjusted OR 0.65, 95% CI 0.27-1.57) and each of the subcohorts (noninstrumented clean spinal, adjusted OR 0.65, 95% CI 0.12-3.44; noninstrumented cranial, adjusted OR 0.52, 95% CI 0.14-2.73; and instrumented cranial, adjusted OR 0.68, 95% CI 0.13-3.31).
Conclusions:
No significant benefit for multiple-dose compared with single-dose AMPs in any of the pediatric neurosurgery settings could be detected. Since unnecessary antibiotic use should be avoided as much as possible, it seems that usage of single-dose AMP is indicated.
