RESUMO
Pediatric head injury is the leading cause of death and disability,about 40% to 60% of kids of head injury get a CT,and the majority are those with minor head injury,about 10% of these CT scans are positive.Clinical decision rules for pediatric head injury exist to identify children at risk of traumatic brain injury.Those of the highest quality are children's head injury algorithm for the prediction of important clinical events(CHALICE),Pediatric Emergency Care Applied Research Network(PECARN)and the Canadian as-sessment of tomography for childhood head injury(CATCH)clinical decision rules.This review aimed to systematically introduce primary clinical decision rules for children with minor head injury and compare them for diagnostic accuracy in detecting intracranial injury and injury requiring neurosurgery.
