| ABSTRACT |
|
A standardized approch to serious head injury employing immediate CT scanning and aggressive medical and surgical therapy has improved outcomes in cases of intracranial lesions. Unfortunately, there is less agreement on how patients with mild head injury should be handled when first seen in an emergency department setting. The ideal policy in mild head injury would be diagnosis or rule-out intracranial lesions as quickly as possible. We reviewed the records of 126 mild head injury patients admitted during 6-month period to the Chonnam University Hospital to identify a group of mild head injury patients having lesions on brain CT scanning and to investigate the risk factors affecting abnormal lesions on brain CT scanning. All patients had alert mental status without neurological deficit and signs of skull fracture. Routine brain CT scans were obtained on all patients. Fifteen patients(12%) had 17 lesions on brain CT scans. Three patients needed surgery for their intracranial lesions. The initial Glasgow Coma Scale(GCS) was 15 in 107 patients and 14 in 19 patients. The incidence of abnormal brain CT lesions for each GCS was 9% in 15 and 26% in 14. The common symptoms of patients who had abnormal brain CT lesions was headache in 7(47%) cases, loss of consciousness in 7(47%) cases, amnesia in 4(27%) cases, dizziness in 4(27%) cases, vomiting in 3(20%) cases, and lethargy in 3(20%) cases. These data suggest that early brain CT scanning is necessary in alert patients who have GCS in 14, headache loss of consciousness, amnesia, dizziness, vomiting, or lethargy following mild head injury. |
