Recommended Protocol for Pediatric Sedation
The recommended pediatric sedation protocol requires practitioners to have the skills to rescue patients from a deeper level of sedation than intended, with immediate availability of age-appropriate resuscitation equipment and personnel trained in airway management. 1
Goals of Pediatric Sedation
The primary goals of pediatric sedation are:
- Guarding patient safety and welfare
- Minimizing physical discomfort and pain
- Controlling anxiety and minimizing psychological trauma
- Providing appropriate cardiopulmonary support if needed 1
Pre-Sedation Assessment
- Evaluate ASA classification: Patients in ASA classes I and II are generally appropriate candidates for minimal, moderate, or deep sedation
- Children in ASA classes III and IV, those with special needs, or anatomic airway abnormalities require additional consideration 1
- Assess for contraindications: history of airway instability, active pulmonary disease, increased intracranial pressure 2
- Document fasting status: 2 hours for clear liquids, 4 hours for breast milk, 6 hours for formula/non-human milk 2
Personnel and Equipment Requirements
Required for All Sedation Levels:
- Pulse oximetry monitoring
- Suction equipment
- Age-appropriate airway management equipment
- Resuscitative medications
- Dedicated monitoring personnel for deep sedation 1, 2
Monitoring Parameters:
- Continuous pulse oximetry
- Heart rate and blood pressure every 5 minutes
- Respiratory status and level of consciousness
- Consider capnography for moderate to deep sedation 2
Medication Selection and Dosing
Ketamine:
- Initial dose: 1-1.5 mg/kg IV or 3-4 mg/kg IM
- Onset: 1-2 minutes (IV), 3-5 minutes (IM)
- Consider atropine premedication (0.02 mg/kg) to reduce secretions 2, 3
- Lower doses (0.5-1.0 mg/kg IV) may be effective for many procedures 3
Midazolam:
- IV: 0.05-0.1 mg/kg titrated slowly (administer over at least 2 minutes)
- Maximum initial dose: 2.5 mg
- Oral: 0.25-0.5 mg/kg (maximum 15 mg) for minimal/moderate sedation 4, 5
- Wait 2-3 minutes between doses to evaluate sedative effect 4
Combination Regimens:
- Ketamine (1 mg/kg IV) with midazolam (0.1 mg/kg IV) provides effective sedation for minor procedures 6
- For needle-free sedation: oral ketamine 6 mg/kg (max 200 mg) with oral midazolam 0.5 mg/kg (max 15 mg) 7
- Note: Combined use increases risk of respiratory depression 2
Procedural Protocol
Preparation Phase:
- Ensure appropriate monitoring equipment is functional
- Confirm availability of resuscitation equipment and reversal agents
- Document pre-sedation vital signs and assessment
Administration Phase:
- Titrate medications slowly to desired effect
- Allow adequate time between doses to assess effect (2-3 minutes)
- Continuously monitor vital signs and sedation level
Procedure Phase:
- Maintain continuous monitoring throughout
- Have a dedicated individual monitor the patient (separate from the person performing the procedure) 1
- Be prepared to rescue from one level deeper than intended sedation
Recovery Phase:
- Continue monitoring until discharge criteria are met
- Document vital signs and recovery parameters
Discharge Criteria
Patients may be discharged when they:
- Return to baseline consciousness
- Have stable vital signs
- Can maintain airway independently
- Are accompanied by a responsible adult 2
Common Pitfalls and Safety Considerations
- Respiratory depression: Most common serious complication involves airway compromise or depressed respirations 1
- Unintended deep sedation: Children commonly pass from intended level to deeper unintended level of sedation 1
- Medication interactions: Enhanced sedative effects when local anesthetics are used with other sedatives 1
- Prolonged sedation: Drugs with long duration (e.g., pentobarbital, phenothiazines) may cause unpredictable responses and prolonged recovery 1
- Age-specific risks: Children younger than 6 years (particularly those under 6 months) may be at greatest risk of adverse events 1
Special Considerations
- Neonates and former preterm infants: Require specific management due to immature hepatic and renal function 1
- Local anesthetic use: Calculate maximum allowable dose before administration; aspirate frequently to minimize intravascular injection 1
- Alternative approaches: Consider non-pharmacological techniques (parental presence, distraction, guided imagery) to reduce sedation requirements 1
Remember that the practitioner must be able to rescue the patient from a deeper level of sedation than intended for the procedure, making the concept of rescue essential to safe sedation practice.
