clinical symptoms of minor head trauma and abnormal computed tomography scan

results loss of consciousness (gcs drop or amnesia) was markedly associated with abnormal brain ct scan (p < 0.05). interestingly, we found 7 patients with normal clinical examination but significant abnormal brain ct scan. conclusions according to the results of our study, we recommend that all patients with minor head trauma underwent brain ct scan in order not to miss any life-threatening head injuries. patients and methods we enrolled 680 patients presented to an academic trauma hospital with minor head trauma in a prospective manner. all participants underwent brain ct scan if they met the inclusion criteria and the results of scans were compared with clinical examination finding. background minor head trauma accounts for 70% to 90% of all head traumas. previous studies stated that minor head traumas were associated with 7% - 20% significant abnormal findings in brain computed tomography (ct)-scans. objectives the aim of this study was to reevaluate clinical criteria of taking brain ct scan in patients who suffered from minor head trauma.
