Objective:

To evaluate the impact of different sedation regimens on long-term cognitive outcomes in pediatric patients.

Approach:

Key Findings:

• Mean estimated IQ was 100.3, comparable to the published test mean of 100.
• Adjusted mean estimated IQ was 98.3 for opioids and benzodiazepines only, 100.6 for multiple sedative classes without dexmedetomidine, and 101.9 for those including dexmedetomidine.
• Patients receiving dexmedetomidine had higher expressive language scores compared to those on opioid and benzodiazepine-only regimens.

Interpretation:

Sedative strategy during pediatric ICU stay was associated with estimated IQ scores.

Limitations:

• No neurocognitive assessments prior to hospitalization to determine baseline function.
• Exclusion of patients with known neurocognitive dysfunction limits generalizability.
• Use of two Wechsler subscales for estimated IQ rather than full-scale testing.
• Potential selection bias due to incomplete long-term follow-up.

Conclusion:

The study indicates that sedation regimens may influence long-term cognitive outcomes in pediatric patients.
