Objective: Minor Head Injury (MHI) patients should not cause severe sequelae. In fact, many studies
had reported that some MHI patients had abnormal scan, clinical deteoritation, and many of them
have had neurosurgical intervention. This study analyzed correlations between clinical signs with
abnormal scan, clinical deteoritation and surgery intervention on minor head injury patients.
Methods: A series of 364 MHI patients were prospectively enrolled in this study. In all cases clinical
data were collected and a CT Scan was obtained. The relationship between clinical findings (loss of
conciousness, amnesia, seizure, vomiting, headache, cepalhameatome, skull fracture, age more than
60 years),were identified as independent risk factors in corelations to abnormal scan, clinical
deteoritation and surgery intervention using bivariate and logistic regresion multivariate analitycs with
95 % CI.
Results: the incidence of abnormal scan was 13.8% (48 patients), 3.3% (12 patients) with clinical
deteoritation, and incidence of surgery intervention was 3.8% (14 patiens). Lost of conciousness,
amnesia, cepalhematoma, skull fracture, and age more than 60 years old are independent variabels
had statisiticly significant with abnormal scan. Amnesia, cepalhematome, skull fracture are
independent variables which had statisitc significantly with clinical deterioritation and surgical
Conclusions: Clinical variables which had statistic significanly can be used as predictors of abnormal
scan, clinical deteoritation, and surgical intervension. Avoiding systematic CT Scan indication implies
a rate of misdiagnosis, but liberal scan can be increasing the cost of patients.
