Etomidate Dosing for Pediatric Conscious Sedation
Dosing Recommendations
- The American Academy of Pediatrics recommends an initial dose of 0.1-0.2 mg/kg IV administered over 30-60 seconds for pediatric conscious sedation 1
- The most effective initial dose is 0.2 mg/kg IV, which provides adequate sedation in approximately 60-67% of pediatric patients 1
- The maximum total dose should not exceed 0.3 mg/kg to minimize adverse effects 2, 3
Administration Protocol
- Etomidate should be administered IV over 30-60 seconds to minimize side effects 1
- Pre-treatment with fentanyl or droperidol can reduce myoclonus 2, 4
- Continuous monitoring of vital signs, oxygen saturation, and level of consciousness is necessary 1, 5
Adverse Effects and Management
- Respiratory depression occurs in approximately 16% of patients, usually manageable with supplemental oxygen and airway repositioning 1
- Myoclonus occurs in approximately 4-38% of patients, and can be reduced with pre-treatment with fentanyl 1, 4
- Oxygen desaturation is reported in 5-39% of patients, with higher risk at doses ≥0.23 mg/kg 3
Monitoring Requirements
- Continuous pulse oximetry and cardiac monitoring are necessary 1, 5
- Regular blood pressure measurements and assessment of respiratory rate and effort are also required 1, 5
- Monitoring of level of consciousness is essential 1, 5
