目的:研究闭合性脑损伤患者入院后进行常规头CT复查的必要性。方法:应用分层分析和Logistic回归分析研究医疗干预和常规复查头CT及其他可能危险因素间的统计学联系。结果:GCS≤8组,常规复查头CT与医疗干预相关;GCS>8组,常规复查头CT与医疗干预无关。结论:(1)GCS≤8的患者常规复查头CT可能受益;(2)GCS>8的患者如果伴有入院后低血压和(或)凝血机制障碍者,也可能从常规复查头CT中受益;(3)其余的患者常规复查头CT没有必要。
Objective: To study the necessity of routine head CT review after admission of patients with closed brain injury. Methods: Stratified analysis and Logistic regression analysis were used to study the statistical relationship between medical intervention and routine CT and other possible risk factors. Results: GCS≤8 group, routine review head CT and medical intervention related; GCS> 8 group, conventional review head CT has nothing to do with medical intervention. CONCLUSIONS: (1) Conventional head CT may benefit patients with GCS ≤ 8; (2) Patients with GCS> 8 may benefit from routine review CT if they have post-admission hypotension and / or clotting disorders ; (3) The remaining patients routine review head CT is not necessary.
