Review Meta Analysis Comparative Study
A common reference-based indirect comparison meta-analysis of intravenous valproate versus intravenous phenobarbitone for convulsive status epilepticus.
To compare intravenous valproate (IV-VPA) with intravenous phenobarbitone (IV-PB) in the treatment of established generalised convulsive status epilepticus (GCSE). Efficacy and safety were estimated using a common-reference based indirect comparison meta-analysis (CRBMA) methodology. ⋯ There is insufficient evidence to demonstrate superiority of IV-VPA over IV-PB for the treatment of GCSE in terms of efficacy. Some direct and indirect comparisons suggest that VPA has a better safety profile than PB. However, the limited numbers of underpowered RCTs included in this meta-analysis are not sufficient to justify a change in clinical practice. More rigorous and appropriately powered RCTs are therefore required to definitively determine the efficacy and tolerability of VPA for the treatment of GCSE.
