Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Although generalized convulsive status epilepticus (GCSE) is a life-threatening emergency, evidence-based data to guide initial drug treatment choices are lacking in the Chinese population. The investigators conduct this prospective randomized controlled trial to evaluate the relative efficacy and safety of intravenous (IV) phenobarbital (PB) and valproate (VPA) in patients with GCSE.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After the failure of first-line diazepam treatment, patients with GCSE are randomized to receive either IV PB (standard doses, low rate) or VPA (standard). Successful treatment is considered when clinical and electroencephalographic seizure activity ceases. Adverse events following treatment and the neurological outcomes at discharge and 3 months later are also evaluated.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Phenobarbital

In the PB group, a loading dose of 20 mg/kg (may give an additional 10 mg/kg) begins at a rate of 50 mg/min followed by IV 100 mg q6 h.

Group Type EXPERIMENTAL

Phenobarbital

Intervention Type DRUG

In the PB group, a loading dose of 20 mg/kg (may give an additional 10 mg/kg) begins at a rate of 50 mg/min followed by IV 100 mg q6 h.

Valproate

In the VPA group, a loading dose of 30 mg/kg (may give an additional 15 mg/kg) begins at a rate of 3 mg/kg per min followed by a continuous infusion at a rate of 1-2 mg/kg per hour.

Group Type EXPERIMENTAL

Valproate

Intervention Type DRUG

In the VPA group, a loading dose of 30 mg/kg (may give an additional 15 mg/kg) begins at a rate of 3 mg/kg per min followed by a continuous infusion at a rate of 1-2 mg/kg per hour.
