Intrathecal nicardipine for symptomatic, refractory vasospasm treatment in pediatric patients: a case series.
Review in Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeVasospasm is a potentially devastating condition that can develop in pediatric patients secondary to traumatic, inflammatory, infectious, and neoplastic etiologies and carries a high risk of morbidity and mortality (Isola et al. 2022, Krishna et al. 2005). Management is often adapted from adult to pediatric care given its relative rarity in children. There is level 3 evidence for the use of intrathecal (IT) calcium channel blocker (nicardipine) administration to treat refractory vasospasm in the adult subarachnoid hemorrhage (SAH) population. Its use has yet to be investigated in children (Krishna et al. 2005). We aim to review the safety profile and efficacy of IT nicardipine for non-traumatic SAH with refractory vasospasm at our institution.
methodsWe present a single institution retrospective series of pediatric patients treated with IT nicardipine for symptomatic vasospasm refractory to standard therapies including oral nimodipine, hyperdynamic augmentation therapies, and targeted intra-arterial therapy.
resultsPediatric patients (n = 3), ages 16-17 years old, admitted with non-traumatic SAH who developed severe, symptomatic, and refractory vasospasm were included. All patients presented with SAH from ruptured aneurysms. A 5-day course of IT nicardipine was initiated using a protocol adapted from our adult cerebrovascular/neurocritical care service. Decreases in peak middle cerebral artery velocity (range 61-290 cm/s) and Lindegaard ratios (range 0.3-4.2) were observed from initiation to completion of treatment.
conclusionsIT nicardipine for pediatric non-traumatic SAH with vasospasm refractory to standard treatments was used in our small series with no complications and no new ischemic events. Clinical and radiographic effects were encouraging. Further study is warranted.
