Coma scale for use in brain-injured children.

Area of Science:

• Pediatric Neurology
• Neurocritical Care
• Clinical Assessment Tools

Background:

• Assessing neurological status in critically ill children is crucial for predicting outcomes.
• Existing coma scales, like the Glasgow Coma Scale, may be limited in preverbal or intubated pediatric patients.
• A need exists for a coma scale adaptable to diverse pediatric central nervous system injuries.

Purpose of the Study:

• To evaluate the association between a novel pediatric coma scale score on admission and the eventual outcome in children with central nervous system injuries.
• To determine the scale's efficacy in predicting outcomes across different pediatric neurological conditions.

Main Methods:

• A coma scale assessing cortical and brainstem function (max score 9) was utilized.
• The scale was applied to 91 children treated for intracranial hypertension.
• Outcome prediction was compared across various etiologies including hypoxic encephalopathy, head trauma, Reye's syndrome, meningitis, and encephalitis.

Main Results:

• A moderately good association was found between admission coma score and eventual outcome.
• The scale demonstrated better predictive accuracy for hypoxic encephalopathy and head trauma compared to Reye's syndrome, meningitis, or encephalitis.
• No child scoring below 3 survived, with most exhibiting flaccidity and absent brainstem reflexes.
• Complete flaccidity on admission was universally associated with non-survival.

Conclusions:

• The developed pediatric coma scale shows potential as a prognostic tool in pediatric neurocritical care.
• The scale's utility is more pronounced in traumatic and hypoxic brain injuries than in infectious or inflammatory conditions.
• Admission neurological status, particularly the absence of motor function and brainstem reflexes, is a critical determinant of survival in pediatric CNS injury.
