Delirium in a Child in Pediatric Intensive Care Unit

Area of Science:

• Pediatrics
• Intensive Care Medicine
• Neuroscience

Background:

• Delirium is a common yet underdiagnosed syndrome in adults, characterized by acute onset, fluctuating course, and impaired consciousness and cognition.
• Diagnosis and detection of delirium in pediatric populations, particularly in the pediatric intensive care unit (PICU), present significant challenges.
• Sedative medications like benzodiazepines and opioids are frequently used in critically ill children, potentially contributing to delirium.

Observation:

• A 2-year-old girl in the PICU with pneumonia developed agitation, restlessness, and dissociation post-extubation after prolonged sedation.
• Electroencephalography revealed diffuse generalized slow wave activity, indicative of altered brain function.
• The child's symptoms improved following environmental modifications, reduction in benzodiazepine dosage, and administration of risperidone.

Findings:

• The case highlights the presentation of delirium in a pediatric patient requiring intensive care.
• Successful management involved a multimodal approach addressing environmental factors and pharmacological interventions.
• The observed EEG findings support the diagnosis of delirium in this pediatric case.

Implications:

• Delirium should be strongly considered in pediatric patients exhibiting altered cognition, consciousness, or circadian rhythm disturbances, especially in the PICU setting.
• Early recognition and appropriate management strategies are crucial for improving outcomes in pediatric delirium.
• Further research is needed to improve the detection and treatment of delirium in children admitted to intensive care units.
