## First-Line Benzodiazepine Dosing in Pediatric Status Epilepticus **Key Point:** Intravenous lorazepam is the first-line benzodiazepine for acute seizure termination in children, with a dose of **0.1 mg/kg IV (maximum 4 mg per single dose)**. ### Rationale for This Dosing - Lorazepam has a longer duration of action (12–24 hours) compared to diazepam, reducing the need for repeated dosing. - The 0.1 mg/kg dose provides rapid CNS penetration and seizure termination within 2–3 minutes. - The 4 mg cap prevents excessive sedation and respiratory depression in pediatric patients. ### Standard Pediatric Status Epilepticus Algorithm | Phase | Drug | Dose | Route | Repeat | |-------|------|------|-------|--------| | **First-line (0–5 min)** | Lorazepam | 0.1 mg/kg (max 4 mg) | IV | Once | | **Alternative first-line** | Diazepam | 0.2 mg/kg (max 10 mg) | IV | Once | | **Second-line (5–20 min)** | Fosphenytoin or Levetiracetam | 20 PE/kg or 20 mg/kg | IV | — | | **Third-line (20–60 min)** | Propofol or Midazolam infusion | Per protocol | IV infusion | — | **High-Yield:** Lorazepam is preferred over diazepam in most pediatric protocols because of its longer half-life and more predictable seizure control, despite diazepam's faster onset. **Clinical Pearl:** If IV access is unavailable, intranasal midazolam (0.2 mg/kg, max 10 mg) is an effective alternative and increasingly used in prehospital and emergency settings.
