Objective      To study the necessity of scheduled repeat cranial computed tomography (CT) scans in patients suffering from mild traumatic brain injury with intracranial hemorrhage based on the first CT scan.        Methods      One hundred and seventeen patients were divided into a scheduled repeat cranial CT group (scheduled group) and non-scheduled repeat cranial CT group (non-scheduled group). The scheduled group

even if clinically stable

was still required to have repeat cranial CT scans within 6 and 24 h

and 3

5  and 7 d after the first CT scan. The non-scheduled group was required to have repeat CT scans ba

sed on neurologic deterioration or at the day before discharge if no neurologic deterioration was observed. Age

gender

score of Glasgow Coma Scale (GCS) at admission

the result of the initial CT scan

radiographic progression

proportion of neurologic interventions

length of hospital stay

score of GCS at discharge

and prognosis at six month after injury were compared between the groups.        Results      There was no significant difference in age

gender

score of GCS at admission

the result of the initial CT scans

radiographic progression

proportion of neurologic interventions

length of hospital stay

score of GCS at discharge

and prognosis between the 2 groups (

P

0.05).       Conclusion      Scheduled repeat cranial CT scans are unnecessary in patients suffering from mild traumatic brain injury with identified intracranial hemorrhage based on the first CT scan after injury

if being closely monitored.
