摘　　要：目的:床旁超声测量视神经鞘直径(ONSD)判断颅内压(ICP)联合Pcv-aCO_(2)/Ca-cvO_(2)指导重型颅脑外伤(TBI)患者院前甘露醇应用的评估价值。方法:采用前瞻性队列研究选择我院2021年1月-2022年1月院前接诊的重型TBI患者,将其中格拉斯哥昏迷评分(GCS)<8分者作为研究对象。院前接诊后,通过床旁超声测量ONSD评估ICP,置入中心静脉导管,采取颈内静脉血样本,计算Pcv-aCO_(2)/Ca-cvO_(2)值。将患者分为4组:A组,Pcv-aCO_(2)/Ca-cvO_(2)>1.8且ONSD>5 mm;B组,Pcv-aCO_(2)/Ca-cvO_(2)>1.8且ONSD≤5 mm;C组,Pcv-aCO_(2)/Ca-cvO_(2)≤1.8且ONSD>5 mm;D组,Pcv-aCO_(2)/Ca-cvO_(2)≤1.8且ONSD≤5 mm。研究期间,院前共接诊343例TBI患者,根据纳入、排除标准,最终275例患者纳入分析,其中A组77例,B组69例,C组70例,D组59例。以死亡或出院作为观察终点。观察、记录并分析是否使用甘露醇在4组间30 d病死率、神经功能恢复情况[通过格拉斯哥预后评分(GOS)进行评估]、住院天数差异。结果:在未经调整的logistic回归分析中,C组患者接受甘露醇治疗是重型TBI患者30 d病死率增高的保护性因素(OR=0.36,95%CI:0.15~0.86,P<0.001)。在调整混杂因素后,C组患者接受甘露醇治疗仍是重型TBI患者30 d病死率增高的保护性因素(OR=0.31,95%CI:0.11~0.73,P=0.004)。其他3组院前使用甘露醇与30 d病死率之间无相关性。Cox生存曲线显示C组患者使用甘露醇后生存率明显提高。结论:ICP监测联合Pcv-aCO_(2)/Ca-cvO_(2)有助于指导院前重型TBI患者甘露醇的使用。Objective:We aimed to investigate the significance of bedside ultrasonography in measurement of optic nerve sheath diameter(ONSD)combined with central venous-arterial carbon dioxide tension to arterial-central venous oxygen content ratio(Pcv-aCO_(2)/Ca-cvO_(2))as indication of mannitol administration in patients with severe traumatic brain injury(TBI).Methods:A prospective cohort study was conducted.The patients admitted to prehospital of patients with severe traumatic brain injury admitted prehospital from January 2021 to January 2022 and Glasgow coma scale<8 were selected as the research objects.We try to use ultrasonographic to measure optic nerve sheath diameter for intracranial pressure monitoring and insert the central venous catheter taken the venous blood samples,then calculate the Pcv-aCO_(2)/Ca-cvO_(2)values.Patients were classified into 4 groups according to Pcv-aCO_(2)/Ca-cvO_(2)and ONSD:Group A,Pcv-aCO_(2)/Ca-cvO_(2)>1.8,ONSD>5 mm;Group B:Pcv-aCO_(2)/Ca-cvO_(2)>1.8,ONSD≤5 mm;Group C:Pcv-aCO_(2)/Ca-cvO_(2)≤1.8,ONSD>5 mm and Group D:Pcv-aCO_(2)/Ca-cvO_(2)≤1.8,ONSD≤5 mm.Death discharge were regarded as the end of observation.The 30-day mortality,functional neurological recovery at discharge(measured by Glasgow Outcome Scale),and length of hospital stay were compared among groups.Results:During the study,343 patients with severe traumatic brain injury were admitted prehospital.According to the inclusion and exclusion criteria,275 patients were included in the analysis,including 77 patients in group A,69 patients in group B,70 patients in group C and 59 patients in group D.In the unadjusted analysis,lower 30-day mortality was substantially decreased in patients who received prehospital mannitol in group C(OR=0.36,95%CI:0.15-0.86,P<0.001),compared with patients who did not receive prehospital mannitol.After adjustment for confounders,a substantial decrease in the odds of 30-day mortality in patients with severe TBI who received prehospital mannitol(OR=0.31,95%CI:0.11-0.73,P=0.004).No association be
