Multicenter Study
Characteristics of vomiting as a predictor of intracranial injury in pediatric minor head injury.
Vomiting is common in children after minor head injury. In previous research, isolated vomiting was not a significant predictor of intracranial injury after minor head injury; however, the significance of recurrent vomiting is unclear. This study aimed to determine the value of recurrent vomiting in predicting intracranial injury after pediatric minor head injury. ⋯ Recurrent vomiting (≥ four episodes) was a significant risk factor for intracranial injury in children after minor head injury. The probability of intracranial injury increased with the number of vomiting episodes and if accompanied by other high-risk factors, such as signs of a skull fracture or altered level of consciousness.
