Predictors of posttraumatic convulsions in head-injured children.

The purpose of this study was to determine predictors of posttraumatic convulsions in children. Study subjects included children under 12 years of age, who were admitted to the Safdarjang Hospital, New Delhi, during the year 1997 (January to December) after suffering head trauma. The occurrence of first convulsion after head injury was taken as the outcome variable in the study. Medical records were reviewed for data about clinical, radiological and epidemiological features of such children. The study revealed that children younger than 2 years of age (odds ratio, OR 2.96; 95% confidence interval, CI 1.42-6.21), those suffering severe head injuries, i.e. with low Glasgow Coma Score (OR 3.07; 95% CI 1.40-6.77), and those with longer period of unconsciousness after head trauma, especially longer than 12 h (OR 1.71; 95% CI 0.69-4.19) have higher likelihood of suffering convulsions after head injury. However, none of the radiological findings were found to be significantly associated with posttraumatic convulsions.
