Predictive Factors for Delayed Surgical Intervention in Children With Epidural Hematomas

BackgroundOptimal treatment of children with traumatic intracranial epidural hematomas (EDHs) is unknown. We sought to identify clinical and radiographic predictors of delayed surgical intervention among children with EDH admitted for observation.MethodsWe retrospectively identified patients younger than 15 years with acute traumatic EDHs evaluated at our level 1 pediatric trauma center. We excluded patients with penetrating head injuries, recent surgical evacuation of EDH, or depressed skull fracture requiring surgical repair and assigned the remaining subjects to the immediate surgery group if they underwent immediate surgical evacuation, to the supportive-therapy-only group if they underwent observation only, and to the delayed surgery group if they underwent surgery after observation. We abstracted clinical and laboratory findings, surgical interventions, and neurological outcome and measured EDH dimensions and volumes, adjusting for cranial size. We compared clinical and radiographic characteristics among groups and performed receiver-operator characteristic analyses of predictors of delayed surgery.ResultsOf 172 patients with EDH, 103 patients met the inclusion criteria, with 6 (6%) in the immediate surgery group, 87 (84%) in the supportive-therapy-only group, and 10 (10%) in the delayed surgery group. Headache, prothrombin time of >14 seconds, EDH maximal thickness of >= 1.1 cm, volume of >= 14 mL, EDH thickness/cranial width index of >= 0.08 and EDH volume/cranial volume index of >= 0.18, and mass effect were associated with delayed surgical intervention. There was no difference in length of stay or functional impairment between the immediate and delayed surgery groups. However, patients in delayed surgery group were more likely to have subjective symptoms at discharge than those in immediate surgery group.ConclusionsAmong patients with EDH admitted for observation, larger EDH, mass effect, headaches, and prothrombin time of >14 seconds were associated with delayed surgical intervention. A larger-scale study is warranted to identify independent predictors of delayed surgery in children under observation for EDH.

Automated summary

Among children with traumatic intracranial epidural hematomas admitted for observation, larger hematoma size, mass effect, headaches, and prolonged prothrombin time were associated with delayed surgical intervention.
