文摘Cerebral blood perfusion and cerebrovascular lesions are important factors that can affect the therapeutic efficacy of thrombolysis.At present,the majority of studies focus on assessing the accuracy of lesion location using imaging methods before treatment,with less attention to predictions of outcomes after thrombolysis.Thus,in the present study,we assessed the efficacy of combined computed tomography（CT） perfusion and CT angiography in predicting clinical outcomes after thrombolysis in ischemic stroke patients.The study included 52 patients who received both CT perfusion and CT angiography.Patients were grouped based on the following criteria to compare clinical outcomes：（1） thrombolytic and non-thrombolytic patients,（2） thrombolytic patients with CT angiography showing the presence or absence of a vascular stenosis,（3） thrombolytic patients with CT perfusion showing the presence or absence of hemodynamic mismatch,and（4） different CT angiography and CT perfusion results.Short-term outcome was assessed by the 24-hour National Institution of Health Stroke Scale score change.Long-term outcome was assessed by the 3-month modified Rankin Scale score.Of 52 ischemic stroke patients,29 were treated with thrombolysis and exhibited improved short-term outcomes compared with those without thrombolysis treatment（23 patients）.Patients with both vascular stenosis and blood flow mismatch（13 patients） exhibited the best short-term outcome,while there was no correlation of long-term outcome with CT angiography or CT perfusion findings.These data suggest that combined CT perfusion and CT angiography are useful for predicting short-term outcome,but not long-term outcome,after thrombolysis.
文摘目的探讨颅内动脉狭窄、血压变异性与急性缺血性脑卒中(AIS)患者神经功能及预后的关系。方法回顾性分析2018年1月—2021年1月收治的AIS 152例的临床资料。根据是否发生早期神经功能恶化(END)分为END组(n=45)和非END组(n=107)。根据卒中发病后90 d的预后情况分为预后良好组(n=60)和预后不良组(n=92)。评估颅内动脉狭窄程度,监测24 h动态血压,计算收缩压标准差(SSD)、舒张压标准差(DSD)。分析影响患者预后的危险因素。结果END组颅内动脉总狭窄率高于非END组,且END组颅内动脉狭窄程度更严重(P<0.05,P<0.01)。END组24 h SSD、24 h DSD、日间SSD、日间DSD、夜间SSD、夜间DSD均高于非END组(P<0.05,P<0.01)。END组杓型血压节律的比例低于非END组,而非杓型血压节律的比例高于非END组(P<0.05,P<0.01)。颅内动脉中、重度狭窄及入院时美国国立卫生研究院卒中量表评分>12分、24 h SSD>12 mmHg、发生END是导致AIS患者预后不良的危险因素,而杓型血压节律为保护性因素(P<0.05,P<0.01)。结论颅内动脉狭窄程度、血压变异性与AIS患者神经功能有关,且是预后的影响因素。
文摘美国国立卫生院卒中量表(National Institute Health stroke scale,NIHSS)评分是临床上常用的脑卒中神经功能缺损评估量表,正确的NIHSS评分有助于更好地评估卒中严重程度和指导临床治疗决策,但现实中NIHSS评分临床使用中存在异质性。如何建立合格的培训模式、助力医务人员规范进行NIHSS评分具有重要意义。文章总结采取“线上+线下”“理论+实践”“案例+思政”“实时+延伸”的教学思路进行“线上+线下+思政+延伸”混合式教学模式的经验,探讨NIHSS评分教学方法,认为该混合式教学模式通过多渠道、多维度的培训模式,使得教学主导、学生主动相结合,并注重思政教育融入,且有助于提高教师教学效率,顺应了信息化时代的教育改革,符合未来教育课程发展的趋势,是NIHSS评分技能培训和改革的新思路和新方法。
文摘目的探讨术中常压高氧(normobaric hyperoxia,NBO)作为辅助神经保护策略联合血管内再通术治疗缺血性脑血管病(ischemic cerebrovascular disease,ICVD)患者的安全性和有效性。方法本研究为单中心回顾性队列研究,共纳入2016年1月至2021年9月就诊于首都医科大学附属北京天坛医院,全身麻醉(以下简称全麻)下行血管内再通治疗、年龄≥60岁及手术时长≥2 h的ICVD患者351例,依据术中吸氧浓度不同,分为H组(100%O_(2),109例)和L组(50%O_(2),242例),采用美国国立卫生研究院卒中量表(National Institute of Health Stroke Scale,NIHSS)评分评估患者神经功能缺损程度,改良Rankin评分量表(modified Rankin Scale,mRS)评分评估患者神经功能恢复状况。比较术后和出院时两组患者NIHSS评分及mRS评分的差异和相关术后并发症(肺炎、再卒中、脑出血)发生情况,利用Spearman相关分析探讨与术后NIHSS评分相关的因素。结果术后和出院时,两组患者NIHSS评分、mRS评分及术后并发症发生率比较,差异均无统计学意义(P>0.05);与H组比较,L组住院时间明显缩短(P<0.05)。术后与NIHSS评分相关的因素为氧浓度、急/平诊、术前狭窄率、狭窄长度、高血脂、术前NIHSS评分、术前mRS评分。结论虽然常压高氧作为ICVD患者血管再通治疗基础上的辅助神经保护策略作用有限,对患者近期神经功能恢复无显著影响,但也未增加术后并发症的发生率。
文摘目的观察基于王居易经络诊察法的温针灸治疗缺血性卒中后偏身感觉障碍的临床疗效。方法选取80例缺血性卒中偏身感觉障碍患者,随机分为对照组和治疗组,每组40例。对照组采用常规取穴针刺;治疗组在对照组的基础上,基于王居易经络诊察法,选取治疗经脉的手足同名经之原穴及合穴进行温针灸治疗。观察两组治疗前后感觉功能评分、改良Barthel指数(modified Barthel index,MBI)评分、美国国立卫生研究院卒中量表(National Institutes of Health stroke scale,NIHSS)评分和中医证候积分的变化,并比较两组的临床疗效。结果两组治疗后感觉功能评分和MBI评分均升高,治疗组高于对照组,差异有统计学意义(P<0.05);两组治疗后NIHSS评分及中医证候积分均下降,治疗组低于对照组,差异有统计学意义(P<0.05);治疗组总有效率高于对照组(P<0.05)。结论在常规取穴针刺治疗的基础上,基于王居易经络诊察法的温针灸治疗缺血性卒中后偏身感觉障碍明显优于常规针刺治疗,可以提升临床疗效,提高自理能力。
