Buccal Midazolam for Pediatric Acute Seizures
For pediatric patients with acute seizures, buccal midazolam should be administered at a dose of 0.3 mg/kg (maximum doses based on age), with seizure cessation typically occurring within 3-4 minutes of administration.
Dosage Protocol
The recommended dosing for buccal midazolam in pediatric patients with acute seizures follows an age-based approach:
| Age | Dose |
|---|---|
| 3 months to <1 year | 2.5 mg |
| 1 year to <5 years | 5 mg |
| 5 years to <10 years | 7.5 mg |
| 10 years to <18 years | 10 mg |
Administration Technique
- Draw up the appropriate dose of midazolam solution
- Place the liquid between the gum and cheek (buccal cavity)
- Administer half the dose on one side of the mouth and half on the other side
- Do not administer during active chewing as this may lead to swallowing and reduced absorption
- Monitor the patient continuously after administration
Efficacy and Timing
Buccal midazolam has demonstrated high efficacy in terminating seizures:
- 84-94% of seizures stop within 10 minutes of administration 1, 2
- Median time to seizure cessation is approximately 3-4 minutes 1
- Most effective when administered for seizures lasting less than 30 minutes (100% efficacy) 1
- Efficacy decreases with longer seizure duration (50% for status epilepticus) 1
Advantages Over Alternative Routes
Buccal midazolam offers several advantages compared to other administration routes:
- More socially acceptable than rectal diazepam 3, 4
- Easier to administer than intravenous medications, especially in community settings
- Similar efficacy to intranasal and intramuscular routes (91% vs 93.3% vs 94.2% in home settings) 2
- High caregiver satisfaction, though intranasal route showed highest satisfaction among caregivers 2
Safety Profile
Buccal midazolam has a favorable safety profile:
- No clinically significant cardiorespiratory events reported in multiple studies 1, 3, 2
- Respiratory depression requiring intervention is rare
- In comparative studies with rectal diazepam, the rate of respiratory depression did not differ between groups 5
Important Considerations
- Monitoring: All patients should be monitored for respiratory depression and oxygen desaturation
- Rescue equipment: Ensure availability of airway management equipment and flumazenil (benzodiazepine antagonist)
- Caution: Be prepared to provide respiratory support regardless of administration route 6
- Contraindications: Use with caution in patients with respiratory compromise or when combined with other sedative agents
Common Pitfalls to Avoid
- Delayed administration: Seizures lasting >5 minutes should be treated promptly
- Improper technique: Ensure the medication is placed between cheek and gum, not swallowed
- Inadequate monitoring: Continue monitoring for at least 30 minutes after administration
- Failure to prepare for complications: Always have airway management equipment readily available
- Not adjusting for prolonged seizures: For seizures lasting >30 minutes, be prepared for potential treatment failure and have backup anticonvulsants ready
Buccal midazolam represents an effective, safe, and socially acceptable first-line treatment for acute seizures in children, with high efficacy rates and minimal adverse effects when administered properly.
