The study reported here sought to identify a group of adult head injury patients in whom computerized axial tomographic (CT) scans were not necessary. The study was limited to patients 18 years of age and older with a history of minor head injury who remained neurologically stable for 20 minutes after arrival at the trauma center, maintained a Glasgow Coma Scale score of at least 13, and had no clinical evidence of basal skull fracture. These patients had a uniformly good neurologic prognosis. The CT scan did not have any prognostic or therapeutic implications. Of a total of 348 patients studied, 12 had an abnormal CT scan with no neurologic deficits or sequelae, and all of them had an uneventful hospital discharge without readmission. It appears that a routine CT scan for minimal head injury patients is an inefficient use of personnel and equipment which may add to the ever increasing financial burden on trauma centers.
本研究旨在确定一组无需进行计算机断层扫描（CT）的成年头部损伤患者。该研究仅限于18岁及以上有轻度头部损伤史的患者，这些患者在抵达创伤中心后20分钟内神经状态保持稳定，格拉斯哥昏迷量表评分至少为13分，且无颅底骨折的临床证据。这些患者的神经预后均良好。CT扫描对预后或治疗并无影响。在总共348例研究患者中，12例CT扫描异常但无神经功能缺损或后遗症，所有这些患者均顺利出院且未再次入院。对于轻度头部损伤患者进行常规CT扫描似乎是对人员和设备的低效利用，这可能会增加创伤中心日益沉重的经济负担。
