Evaluating the Benefits of Ventriculostomy Compared to Intracranial Pressure Monitoring for Severe Pediatric Traumatic Brain Injury.

Background: In this study, we compared outcomes between intracranial pressure monitoring (ICP) only versus ventriculostomy (VT) using a nationwide database of pediatric trauma patients.

Methods: Pediatric patients (<18 years) with severe blunt TBI who underwent ICP monitoring with or without VT were identified from the 2017-2021 ACS Trauma Quality Programs. We excluded patients who experienced death or craniotomy/craniectomy within 48 h. The primary outcome was discharge disposition. Secondary outcomes were subsequent intracranial surgery, length of stay (LOS), and infectious complications. Competing risks survival analysis was used to evaluate the multivariable association between ICP vs. VT and outcomes.

Results: Of 1719 eligible patients, 65.9% were male and 54.1% had VT. Between the ICP and VT groups, there were no differences in mean age (11.4 vs. 11.0 years, p = 0.145), injury severity score (30.9 vs. 30.9, p = 0.937), or median GCS (3 vs. 3, p = 0.120). Multivariable analysis showed a robust association between VT and discharge home (compared to rehabilitation center; sHR 0.85, 95% CI 0.74-0.97, p = 0.017). VT use was not associated with increased mortality compared to ICP (p = 0.342). Finally, VT patients had longer median LOS (20.5 vs. 18.0 days, p < 0.001) but there was no difference in subsequent craniotomy/craniectomy (8.6 vs. 6.5%, p = 0.096) or infectious complications (1.2 vs. 0.9%, p = 0.549).

Conclusion: VT was associated with greater discharge to home. Although VT patients had a greater LOS, the risk for other secondary outcomes did not vary, suggesting that VT may have benefits for the treatment of severe TBI with respect to discharge disposition.

Level of evidence: III.
