Insights
Early external ventricular drainage (EVD) in premature infants with posthemorrhagic hydrocephalus is safe and effective. This approach, involving prolonged drainage before shunting, shows favorable outcomes compared to traditional methods.
Area of Science:
- Neonatalogy
- Pediatric Neurosurgery
- Critical Care Medicine
Background:
- Progressive posthemorrhagic hydrocephalus is a serious complication in premature infants.
- Traditional management may involve lumbar punctures or delayed shunting, with associated risks.
- Optimizing treatment for this vulnerable population is crucial.
Purpose of the Study:
- To evaluate the safety and efficacy of early external ventricular drainage (EVD) for progressive posthemorrhagic hydrocephalus in premature infants.
- To compare outcomes of early EVD followed by delayed shunting with historical controls managed by lumbar punctures and late shunting.
Main Methods:
- A cohort of 14 premature infants with progressive posthemorrhagic hydrocephalus underwent early EVD.
- Catheters were inserted in the neonatal intensive care unit for stability.
- External ventricular drainage was maintained for an average of 38.4 days before considering ventriculoperitoneal shunting, ideally after reaching 2000 g body weight.
Main Results:
- No infections or significant drainage-related complications were observed.
- Mean daily EVD volumes and duration were recorded.
- Nine out of 14 infants ultimately required permanent shunting.
- Mortality and morbidity data at 3 months follow-up were favorable compared to an earlier cohort.
Conclusions:
- Early external ventricular drainage in premature infants with posthemorrhagic hydrocephalus is a safe and effective management strategy.
- This approach, with prolonged drainage prior to shunting, demonstrates improved outcomes and reduced complications.
- The findings support a shift towards early EVD as a preferred treatment policy.
Abstract:
To treat progressive posthemorrhagic hydrocephalus we used early external ventricular drainage (EVD) in 14 premature infants. We think it is important that the catheters in these critically ill infants be inserted in the neonatal intensive care unit, allowing us to keep the infants in an extremely stable environment. Only after prolonged external ventricular drainage (on average 38.4 days) is a ventriculoperitoneal shunt considered, preferably when the child has reached a body weight of 2000 g. There were no infections or other severe drainage-related problems. We report mean daily EVD volumes (which are related to body weight) and EVD duration. The 14 patients included 9 who required permanent shunting. Comparing the mortality, morbidity and follow-up data to at least 3 months of age in this group with similar data for an earlier cohort treated with lumbar punctures and late permanent shunting, we demonstrate the safety of the policy we have recently adopted.
