神经元特异性烯醇化酶和S100蛋白评估心脏停搏患者复苏后脑损伤的研究 总被引:8,自引:11,他引:8
目的观察血清神经元特异性烯醇化酶(NSE)和S100蛋白水平对心脏停搏(CA)患者心肺复苏(CPR)后脑损伤预后评估的价值。方法将25例CPR患者根据6个月时是否恢复意识分为两组。检测患者在自主循环恢复(ROSC)后2、12、24、48和72h的血清NSE和S100蛋白水平,分析两组在不同时间点NSE和S100蛋白水平之间的差异,并与健康对照组进行比较。描绘两种诊断方法的受试者工作特征曲线(ROC曲线)并计算曲线下面积进行分析。结果①意识未恢复组血清NSE水平在ROSC后12、48和72h,S100蛋白水平在ROSC后2、12、48和72h均明显高于意识恢复组(P均〈0.01)。②意识恢复组12h和24h的NSE水平与12h的S100蛋白水平均较健康对照组高(P均〈0.05);而意识未恢复组各时间点的NSE水平及12、48和72h的S100蛋白水平均较健康对照组增高显著(P〈0.05或P〈0.01)。③血清NSE和S100蛋白两种诊断方法曲线下面积分别为0.848(P=0.000)和0.896(P=0.000),对判断CA患者CPR后能否恢复意识具有较高的诊断意义。S100蛋白以0.165μg/L为临界值,ROSC后2h其敏感度、特异度、阳性预告率、阴性预告率及准确率最高,分别为94.4%、100.0%、100.0%、80.0%和95.5%,NSE以45.6μg/L为临界值,则以ROSC后48h各指标最满意,均达到100.0%。结论血清NSE和S100蛋白水平对评价CPR后患者的脑损伤程度及能否恢复意识具有诊断意义,两者联合动态观察,对严重而持续的脑损伤更有诊断价值。 相似文献

OBJECTIVE: The aim of this study was to investigate whether serial serum neuron-specific enolase (NSE) can be used to predict neurological prognosis in patients remaining comatose after cardiopulmonary resuscitation (CPR). DESIGN. Observational cohort study. Clinicians were blinded to NSE results. SETTING: Eighteen-bed general ICU. PATIENTS: Comatose patients admitted to the ICU after CPR. INTERVENTIONS: Serum NSE was measured at admission and daily for 5 days. MEASUREMENTS AND RESULTS: Patients received full intensive treatment until recovery or until absence of cortical response to somatosensory evoked potentials more than 48 h after CPR proved irreversible coma. Of the 110 patients included (mean GCS at ICU admission 3, range 3--9), 34 regained consciousness, five of whom died in hospital. Seventy-six patients did not regain consciousness, 72 of whom died in hospital. Serum NSE at 24 h and at 48 h after CPR was significantly higher in patients who did not regain consciousness than in patients who regained consciousness (at 24 h: median NSE 29.9 microg/l, range 1.8-250 vs 9.9 microg/l, range 4.5-21.5, P<0.001; at 48 h: median 37.8 microg/l, range 4.4-411 vs 9.5 microg/l, range 6.2-22.4, P= 0.001). No patient with a serum NSE level >25.0 microg/l at any time regained consciousness. Addition of NSE to GCS and somatosensory evoked potentials increased predictability of poor neurological outcome from 64% to 76%. CONCLUSIONS: High serum NSE levels in comatose patients at 24 h and 48 h after CPR predict a poor neurological outcome. Addition of NSE to GCS and somatosensory evoked potentials increases predictability of neurological outcome. 相似文献

BACKGROUND AND PURPOSE: Patients resuscitated from cardiac arrest are at risk of subsequent death or poor neurological outcome up to a persistent vegetative state. We investigated the prognostic value of several epidemiological and clinical markers and two neuroproteins, neuron-specific enolase (NSE) and S-100 protein (S-100), in 97 patients undergoing cardiopulmonary resuscitation (CPR) after non-traumatic cardiac arrest between 1998 and 2002. RESULTS: 52.6% of the patients died, 28.8% survived with severe, moderate or without neurological disorders, and 18.6% remained in a persistent vegetative state. Unconsciousness>48 h after CPR predicted a 60.6-fold (95% CI 14.3287-257.205, p=0.001) and a Glasgow Coma Scale (GCS)<6 points after 72 h a 11.2-fold (CI 95%, 3.55-36.44, p<0.001) risk of poor neurological outcome. Serum levels>or=65 ng/ml for NSE and >or=1.5 microg/l for S-100 increased the risk of death and persistent vegetative state 16.8 (95% CI 2.146-131.520)- and 12.6 (95% CI 1.1093-99.210)-fold, respectively. By combination of the GCS with elevated serum concentrations of both neuroproteins above the cut off levels on third day after CPR a poor neurological outcome was predicted with a specificity of 100%. CONCLUSION: The combination of GCS with the serum levels of both neuroproteins at 72 h after CPR permit a more reliable prediction of outcome in post arrest coma than the single markers alone, independent of the application of anaesthetic agents. 相似文献

BACKGROUND: Paediatric patients with out-of-hospital cardiac arrest (OHCA) due to trauma pose difficult challenges in resuscitation. Trauma is a major cause of OHCA in children. The aim of this study was to determine which factors were related to predicting a sustained return of spontaneous circulation (ROSC) in paediatric OHCA patients with trauma. METHOD: This retrospective study comprised 115 paediatric patients (56 traumatic and 59 non-traumatic OHCA patients) aged younger than 18 years who had been admitted to the emergency department (ED) from January 2000 to December 2004. We analysed the demographic data and the factors that may have influenced sustained ROSC in the group of OHCA paediatric patients with trauma. The non-trauma group was established as a control group. Survival analysis was used to compare differences in survival rate between trauma and non-trauma OHCA patients. Receiver operating characteristic (ROC) analysis was used to determine the significant in-hospital CPR duration related to sustained ROSC. RESULTS: Initial cardiac rhythm on arrival (P=0.005) and the duration of in-hospital CPR (P<0.001) were significant factors. Patients with PEA or VF had higher rate of sustained ROSC than those with asystole (PEA: P=0.003, VF: P=0.03). In the survival analysis, OHCA children with trauma had a lower chance of survival than non-trauma children as the interval from the scene to the ER increased (P=0.008). Based on the ROC analysis, the cut-off values of in-hospital CPR duration were 25min in OHCA paediatric patients with trauma. CONCLUSION: Several significant factors relating to sustained ROSC were determined in the OHCA paediatric patients with trauma; most importantly, we found that in-hospital CPR may have to be performed for at least 25min to enable a spontaneous circulation to return. 相似文献

OBJECTIVE: To determine the effect of a return of spontaneous circulation (RO SC) on survival to hospital discharge as compared to other established predictors of survival. METHODS: A retrospective case review of all out-of-hospital primary cardiac arrests from 01 January, 1992 to 31 December 1994 was conducted. The relative values of age, race, gender, presenting cardiac rhythm, witnessed event, initiation of CPR by bystanders, response time intervals, and return of spontaneous circulation (ROSC) in an Utstein-template database were tested as predictors of survival of patients who had suffered a cardiac arrest in the out-of-hospital setting. The ROSC was defined as return of spontaneous circulation prior to and present upon arrival at the emergency department. Predictors were evaluated for statistical significance using a logistic regression analysis (p < 0.05). Odds ratios (OR) and 95% confidence intervals (CI) with positive and negative predictive values (PPV, NPV) were calculated. RESULTS: Of 832 patients with primary cardiac arrest, 153 (18.4%) had ROSC and 67 (8.1%) survived to hospital discharge. Comparing survivors to nonsurvivors, the mean values for age were 64 to 67 years, with 59.7% to 36.1% being witnessed, 35.8% to 23.9% having bystander CPR initiated, 88.1% to 48.4% having ventricular fibrillation (V-fib) and 82.1% to 64.0% having ROSC. An initial electrocardiographic rhythm of V-fib (p = 0.009; OR = 2.2; CI = 1.2-3.9), and ROSC (p < 0.0001; OR = 5.2; CI = 3.6-7.5) are statistically significant predictors of survival to hospital discharge. The PPV was 13.8% for V-fib and 35.9% for ROSC, and the NPV was 98.0% for V-fib and 98.2% for ROSC. CONCLUSION: Presenting V-fib and out-of-hospital ROSC are significant predictors of survival from cardiac arrest. Failure to obtain ROSC in the out-of-hospital setting strongly suggests consideration for terminating resuscitation efforts. 相似文献

Purpose of the studyWhile the outcomes of cardiopulmonary resuscitation (CPR) for pediatric in-hospital cardiac arrest (IHCA) are reported for many regions, none is reported for Asian countries. We report the outcomes of CPR for pediatric IHCA in a tertiary medical center in Taiwan and also identify prognostic factors associated with poor outcome.MethodsData were retrieved retrospectively from 2000 to 2003 and prospectively from 2004 to 2006 from our web-based registry system. We evaluated patients younger than 18 years of age who had IHCA and received CPR. The primary outcome was survival to hospital discharge, and the secondary outcomes were sustained return of spontaneous circulation (ROSC), and favorable neurological outcomes as assessed by pediatric cerebral performance categories (PCPC).ResultsWe identified 316 patients and the overall hospital survival was 20.9% and 16.1% had favorable neurological outcomes. Sixty-four patients ever supported with ECMO. We further analyzed 252 patients who underwent conventional CPR only and most had cardiac disease (133/252, 52.8%). The second most common preexisting condition was hematologic or oncologic disease (43/252, 17.1%). Of the 252 patients, 153 (60.7%) achieved sustained ROSC, 50 (19.8%) survived to discharge, and 39 patients (15.5%) had favorable neurological outcomes. CPR during off-work hours resulted in inferior chances of reaching sustained ROSC. Multivariate analysis showed that long CPR duration, hematology/oncology patients, and pre-arrest vasoactive drug infusion were significantly associated with decreased hospital survival (p < 0.05).ConclusionsOutcomes of CPR for pediatric patients with IHCA in Taiwan were comparable to corresponding reports in Western countries, but more hematology/oncology patients were included. Long CPR duration, hematologic or oncologic underlying diseases, and vasoactive agent infusion prior IHCA were associated with poor outcomes. The concept of palliative care should be proposed to families of terminally ill cancer patients in order to avoid unnecessary patient suffering. Also, establishing a balanced duty system in the future might increase chances of sustained ROSC. 相似文献

vs. 55 (48,62.2)],差异有统计学意义(
P<0.05)。NSE及BIS预测神经不良预后的AUC分别为0.768(0.685,0.839)和0.866(0.793,0.920),截断值分别为21.7 ng/mL和47;两者联合预测神经不良预后的AUC为0.927(0.867,0.966),明显高于单一指标(
P<0.05)。

结果预后不良组心脏骤停患者基底节GWR [1.15(1.10,1.22)vs. 1.26 (1.22,1.28),Z = 4.576,P < 0.001]较预后良好组显著降低,而体外膜肺氧合建立后72 h内血清NSE峰值[205.80(105.00,370.00)μg/L vs. 41.25(31.96,52.07)μg/L,Z = 5.910,P < 0.001]显著升高。Spearman相关分析结果显示,基底节GWR与NSE水平呈显著负相关(r = -0.685,P < 0.001)。ROC曲线分析结果显示,基底节GWR [曲线下面积(AUC)= 0.831,95%置信区间(CI)(0.735,0.926),P < 0.001]及NSE 72 h内峰值[AUC = 0.926,95%CI(0.859,0.992),P < 0.001]均对心脏骤停患者神经功能不良预后具有预测价值。基底节GWR < 1.18时,其预测神经功能不良预后的敏感度和特异度分别为62.8%和92.3%。ECMO建立后72 h内NSE峰值> 79.49 μg/L时,其预测不良预后的敏感度为83.7%,特异度为100%。
结论ECPR患者24 h内头颅CT提示GWR降低、72 h内NSE水平升高可作为预测神经功能预后不良的有效手段。 相似文献

目的 观察院内心肺复苏后不同时间点组织因子(TF)和组织因子途径抑制物(TFPI)水平的动态变化特点并探讨其临床意义.方法 选择2005年9月至2007年9月温州医学院附属第一医院急诊科收治的年龄>16岁明确心搏停止时间的心肺复苏患者24例,依据是否达到自主循环恢复标准随机分为ROSC和末ROSC两组,分别记录小同患者心搏停止的病因和临床特点,并用ELISA方法 检测心肺复苏(CPR)后30 min,60 min,6 h,24 h,48 h血清TF和TFPI抗原浓度,10例来自健康体检的健康自愿者为对照组.计量数据用均数±标准差((-x)±s)来表示,两组计量数据的比较采用独立样本t检验,三组及以上计量数据比较采用单因素方差分析法,计数数据的比较采用旧格表精确x2榆验,以P<0.05为差异具有统计学意义.结果 与对照组比较,ROSC组患者在CPR 30 min血TF水平显著升高(P<0.01),在CPR 6 h达高峰,在CPR48 h时已下降;与对照组及ROSC组同时点比较,末ROSC组血TF水平更是显著升高(P<0.01).与对照组比较,在CPR后30 min,ROSC和未ROSC两组血清TFPI水平差异无统计学意义(P>0.05),60 min后ROSC组血清TFPI水平逐渐升高并有显著差别(P<0.01或<0.05).与对照组比较,未ROSC组和ROSC组患者在CPR 30 min时的TF/TFPI水平均显著性升高(P<0.01),且前者显著高于后者(P<0.01),在ROSC组IF/TFPI值在CPR后6 h有显著升高(P<0.01),在48 h下降.结论 血清TF和TFPI水平在院内心肺复苏的患者中明显升高,CPR后半小时的TF和TF/TFPI的水平可用于判断预后. 相似文献
