摘 要:目的评价临床上用于〉35周胎龄新生儿缺氧缺血性脑病远期神经发育预后评价体系的预测价值。方法检索时间区间从1980年1月至2012年12月。用“新生儿缺氧缺血性脑病”“远期预后”“预测”和“neonateswithhypoxic—ischemicencephalopathy”“prognostictest”为检索词分别检索中国知网一中国学术期刊网络出版总库、万方数据库、Pubmed、Embase数据库中的相关文献。纳入研究需同时满足:(1)胎龄〉35周患有围产期窒息或HIE的新生儿的预后研究;(2)神经发育结局至少随访到18月龄及以上;(3)神经发育结局明确预后良好或不良。采用RevMan5.2软件对满足纳入标准的相关研究进行荟萃分析,评价各种检测方法的敏感度和特异度。结果共检索出260篇相关文献,对20篇符合纳入标准的研究进行荟萃分析。符合条件的评价指标包括振幅整合脑电图(aEEG),磁共振成像(MRI)[T1/T2加权、弥散加权像(DWI)、表观弥散系数(ADC)和磁共振波谱(MRS)],颅脑超声和临床分度。结果显示,目前最有前景的是aEEG敏感度0.936(95%CI:0.897~0.964);特异度0.884(95%C/:0.836—0.921)。影像学上,T1/T2加权像灵敏度0.913(95%CI:0.850—0.956),特异度0.630(95%CI:0.544—0.711);DWI灵敏度0.933(95%CI:0.817~0.956),特异度0.694(95%CI:0.546—0.817);ADC灵敏度0.778(95%CI:0.664—0.867),特异度0.971(95%c,:0.898—0.996);MRS灵敏度为0.918(95%CI:0.804~0.977),而特异度0.642(95%CI:0.515~0.755)。颅脑超声灵敏度0.683(95%CI:0.519~0.819),特异度0.459(95%CI:0.295—0.631)。临床分度灵敏度0.967(95%CI:0.924—0.989),特异度0.314(95%CI:0.241~0.394)。结论证据表明,aEEG,MRI(T1/T2、DWI、ADC、MRS),�Objective To explore the prognostic value of currently used clinical tests in neonatal patients over 35-week gestational age with perinatal asphyxia and hypoxic-ischemic eneephalopathy (HIE). Methods " Neonate hypoxic-ischemic encephalopathy " and " prognostic test" were used as key words. Searches were made on the databases of PubMed, EMBASE, CNKI and WanFang for studies published between January 1980 and December 2012. Studies were included if they ( 1 ) evaluated outcome in over 35- week gestational age neonates with perinatal asphyxia or HIE; (2) reported outcomes at minimal follow-up age of 18 months; (3) confirmed neurodevelopment with favorable or adverse outcomes. RevMan 5. 2 software 1.4 was used for meta-analysis. And the evaluation criteria of each study were employed to assess and analyze the results comprehensively. Results Among 260 relevant studies, 20 were included. There are 7 tests contented our inclusion criteria: amplitude-integrated electroencephalography ( aEEG ) , magnetic resonance imaging (MRI :T1/T2 weighted imaging, diffusion weighted imaging (DWI), apparent diffusion coefficient (ADC), magnetic resonance spectroscopy (MRS) ), cerebral ultrasound (CUS) and HIE stage. The most promising tests were aEEG: sensitivity 0. 936 (95% CI: O. 897 -0. 964) ; specificity 0. 884(95% CI: O. 836 - 0. 921 ). In imaging, T1/T2-weighted MRI sensitivity 0. 913 ( 95% CI: O. 850 - O. 956 ), specificity O. 630 (95% CI: O. 544 -O. 711 ) ; diffusion weighted MRI sensitivity 0. 933 (95% CI: O. 817 -0. 956 ), specificity 0. 694(95% CI: O. 546 - 0. 817) ; ADC sensitivity 0. 778 (95% CI: 0. 664 - 0. 867), specificity 0. 971 (95 % CI: 0. 898 - 0. 996) ; MRS sensitivity 0. 918 ( 95 % CI: 0. 804 - 0. 977 ), specificity 0. 642 ( 95 % CI: O. 515 -0. 755). CUS sensitivity 0. 683 (95% CI: O. 519 - 0. 819), specificity 0. 459 (95% (21: O. 295 - 0. 631 ). HIE stage sensitivity 0. 967 ( 95% CI:
