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 deterioration, and many of them have had neurosurgical intervention. This study analyzed correlations between clinical signs with abnormal scan, clinical deterioration 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 correlations to abnormal scan, clinical deterioration and surgery intervention using bivariate and logistic regression multivariate analytics with 95 % CI.
Results: the incidence of abnormal scan was 13.8% (48 patients), 3.3% (12 patients) with clinical deterioration, 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 statistically significant with abnormal scan. Amnesia, cepalhematome, skull fracture are independent variables which had statistic significantly with clinical deterioration and surgical intervention.
Conclusions: Clinical variables which had statistic significantly can be used as predictors of abnormal scan, clinical deterioration, and surgical intervention. Avoiding systematic CT Scan indication implies a rate of misdiagnosis, but liberal scan can be increasing the cost of patients
